Printer states

The printer may be in any one of the following states; some of them require waiting.

●

Ready (cold): The printer is powered on but has not printed yet, and the heaters are not turned on.

●

Preparing to print: The printer is warming up the heaters and preparing the printheads to print. This takes 1 to 6 min.

●

Ready for substrate

●

Ready for side A/B

●

Printing

●

Printing side A/B

●

Drying: This takes 1.5 to 5 min.

●

Finishing: The printer is cooling down and preparing for stand-by. This takes 0.5 to 5 min.

If jobs of the same print mode as the already-printed file are sent while the printer is Drying or Finishing, the printer goes to Preparing to print.

To save time between prints, you are recommended to use nesting to print several jobs in the same workflow.

Change margins

The printer margins determine the area between the edges of your image and the edges of the substrate.

The side margins for a particular print job are selected in the RIP software; if the job exceeds the substrate width, it will be clipped.

The front panel offers additional settings for the top and bottom margins: see Table 11-4 Margins

on page 144. These settings apply only to single prints.

To set the top margin at the front panel, press , then Substrate > Substrate handling options > Extra

top margin

To set the bottom margin at the front panel, press , then Substrate > Substrate handling options >

Join the Customer Involvement Program

You can activate or deactivate the Customer Involvement Program from the Embedded Web Server or from the printer's front panel.

NOTE: From the front panel, press , then Setup > Customer Involvement Program.

The Customer Involvement Program is a statistical printer-usage tracking system. It may also be used to determine eligibility for certain usage-based reward programs, or to monitor the device in connection with optional services such as proactive cartridge replacement, pay-per-use contracts, or support agreements (availability varies by product, region, and country). See the Customer Involvement Program tab of the Embedded Web Server for details on the data collected and HP’s use of the data. Once the Customer Involvement Program is enabled, your printer will automatically send 'usage snapshots' to HP through the Internet approximately once a week, for as long as the Customer Involvement Program remains enabled. The snapshot files are collected on a repository server, then automatically processed to extract the relevant data, which are stored in a usage database. Sending the data does not interfere with the normal operation of your printer, and does not require attention of any kind. You can stop participating at any time, in which case data transmissions stop immediately.

The CIP configuration page of the Customer Involvement Program tab is where you can start, stop, or change your participation in the Customer Involvement Program. By default, only anonymous usage data are sent to HP, but you have the option to include the printer’s serial number. This may be necessary for certain programs or services, and may allow us to provide you with better product service and support. Once you have made any changes to the settings, click the Apply button to apply them.

If the Customer Involvement Program was enabled before clicking the Apply button, a connectivity test is automatically made to determine whether Customer Involvement Program data can be successfully delivered to HP.

20 Chapter 1 Introduction ENWW

If the test completes successfully, configuration is complete and you can proceed to any other Embedded Web Server page, or close the browser window. If the test fails, follow the instructions to try to identify and fix the problem.

The CIP status and test page of the Customer Involvement Program tab can be used to check the current status (enabled or not, anonymous data or not), and to run a connectivity test to check that Customer Involvement Program data can be successfully delivered to HP.

Check printer status

The front panel and the Embedded Web Server both display the status of the printer, the loaded substrate, and the ink system.

Check the status of the ink system

1. Access the Embedded Web Server (see Access the Embedded Web Server on page 19).

2. Go to the Supplies page on the Main tab.

The Supplies page shows you the status of the loaded substrate, the ink cartridges, the printheads, the heater, and the maintenance cartridge.

The traffic light shows whether maintenance is required.

Request email notification of specific error conditions

1. In the Embedded Web Server (see Access the Embedded Web Server on page 19), go to the Email Server

page on the Setup tab and ensure that the following fields are correctly filled in:

●

SMTP server. This is the IP address of the outgoing mail server (Simple Mail Transfer Protocol [SMTP]) that processes all email messages from the printer. If the mail server requires authentication, email notifications will not work.

●

Printer email address. Each email message that the printer sends must include a return address. This address does not need to be a real, functional email address, but it should be unique, so that recipients of the message can identify the printer that sent it

2. Go to the Notification page, which is also on the Setup tab.

3. Click the New icon to request new notifications, or click the Edit icon to edit notifications that have

already been set up. Then specify the email addresses to which notifications are sent, and select the incidents that result in notification messages.

Get accounting information

There are various different ways of getting accounting information from your printer.

●

View printer usage statistics for a particular job, see Check usage statistics for a job on page 22.

●

View printer usage statistics for the whole lifetime of the printer, see Check lifetime usage statistics

on page 22.

●

Request accounting data by email. The printer sends data in XML at regular intervals to a specified email address; the data may be interpreted and summarized by a third-party application, or displayed as an Excel spreadsheet. See Request accounting data by email on page 23.

●

Use a third-party application to request printer status, printer usage or job accounting data from the printer through the Internet. The printer provides data in XML to the application whenever requested. HP provides a Software Development Kit to facilitate the development of such applications.

By default, user names are not included in accounting information. If you would like to include them, check the box Show user name in job accounting in the Security menu.

Check usage statistics for a job

You can use the Embedded Web Server to check usage statistics for a particular job: go to the Main tab and select History > Accounting.

22 Chapter 1 Introduction ENWW

Request accounting data by email

1. Obtain the IP address of the outgoing mail server (SMTP) from your IT department; this is required in

order to send email messages.

2. Ensure that the outgoing email server is configured to enable relaying of email messages that the

printer will send.

3. Open your Web browser and connect to the printer’s Embedded Web Server.

4. Select the Setup tab.

5. From the Configuration menu in the left-hand column, select Date & Time.

6. Ensure that the printer's date and time have been set correctly.

7. From the Configuration menu, select Email server.

8. Enter the IP address of the outgoing mail server (SMTP).

9. Specify an email address for the printer. The latter does not need to be a valid email address, because

the printer will not receive messages; but it should have the form of an email address. It serves to identify the printer when it sends email messages.

10. From the Configuration menu, select Printer settings.

11. Set Send accounting files to Enabled.

12. Set Send accounting files to to the email address (or addresses) to which you want the accounting

information sent. This may be an address that you have created specifically to receive automatically generated messages from the printer.

13. Set Send accounting files every to the frequency with which you want the information sent, choosing a

specific number of days or prints.

14. You may want to set Exclude personal information from accounting email to On, so that the

accounting messages will not contain personal information. If this option is Off, information such as user name, job name, and account ID will be included.

When you have completed the above steps, the printer will send accounting data by email with the frequency that you specified. The data are provided in XML and can easily be interpreted by a third-party program. The data provided on each print job include when the job was submitted, when the job was printed, the printing time, the type of image, the number of pages, the number of copies, the paper type and size, the amount of each color of ink used and various other attributes of the job. Accounting data are also provided on scan and copy jobs.

You can download an Excel template from HP's Web site (http://www.hp.com/go/designjet/accounting/) that will enable you to display the XML data more readably in the form of a spreadsheet.

Analysis of the accounting data will enable you to bill customers precisely and flexibly for the use of your printer. You can, for instance:

●

Bill each customer for the total amount of ink and paper used by that customer over a particular period.

●

Bill each customer separately per job.

●

Bill each customer separately for each project, broken down by job.

Connectivity and software instructions

Connection method

Your printer can be connected in the following way.

Connection type Speed Maximum cable length Other factors

Gigabit Ethernet Fast; varies according to

network traffic

NOTE: The speed of any network connection depends on all the components that are used in the network,

which can include network interface cards, hubs, routers, switches, and cables. If any one of these components cannot operate at high speed, you will have a low-speed connection. To get the expected performance from your printer, you should use equipment that supports 1000TX Full Gigabit. The speed of your network connection can also be affected by the total amount of traffic from other devices on the network.

Connect the printer to your network

The printer is able to configure itself automatically for most networks, in a similar way to any computer in the same network. The first time you connect it to a network, this process may take a few minutes. If necessary, see Advanced network configuration on page 25.

Once the printer has a working network configuration, you can check its network address from the front

panel: press .

Network configuration

For more details about the current network configuration, go to the front panel and press , then

Using IPv6

Connectivity > Network connectivity > Gigabit Ethernet > Modify configuration. From here it is possible,

though not normally necessary, to change the settings manually; this can also be done remotely using the Embedded Web Server.

TIP: You may find it helpful to print out the full printer network configuration on paper. This can be done

from the front panel: press , then Internal prints > Service information prints > Print connectivity

configuration

IP address and network name.

If you accidentally misconfigure the printer’s network settings, you can restore the network settings to their

factory values from the front panel: press , then Connectivity > Network connectivity > Advanced >

Restore factory settings. Then you must restart the printer. This automatically provides a working network configuration for most networks. The printer’s other settings remain unchanged.

Your printer supports almost all network connectivity features using IPv6, just as it does using IPv4. To make full use of IPv6, you may need to connect your printer to an IPv6 network in which there are IPv6 routers and servers.

In most IPv6 networks, the printer will configure itself automatically as follows, and no user configuration is necessary:

. If you do not print out the full network configuration, consider making a note of the printer's

24 Chapter 1 Introduction ENWW

1. The printer assigns itself a link-local IPv6 address (which starts with “fe80::”).

2. The printer assigns itself stateless IPv6 addresses as indicated to it by any IPv6 routers on the network.

3. If no stateless IPv6 addresses can be assigned, the printer will try to obtain IPv6 addresses using

DHCPv6. It will also do so if the routers instruct it to do so.

The stateless and DHCPv6 IPv6 addresses can be used to access the printer, and in most IPv6 networks this will be appropriate.

The link-local IPv6 address works only in the local subnet. Although it is possible to access the printer using this address, it is not recommended.

It is possible to assign a manual IPv6 address to the printer, using the front panel or the Embedded Web Server. It is also possible to disable IPv6 completely in the printer. However, it is not possible to disable IPv4 in the printer, and therefore it is not possible to configure the printer as IPv6-only.

NOTE: In typical IPv6 use, your printer will have multiple IPv6 addresses, although it has only one IPv4

address.

TIP: You are recommended to give a name to the printer. You can do this from the front panel or (more

easily) from the Embedded Web Server.

TIP: You will generally find it easier to use IPv4 unless you have a specific need to use IPv6.

Microsoft Windows Vista, Microsoft Windows Server 2008, later versions of Windows, and the new HP Printing and Imaging devices have IPv6 enabled by default. For further information on IPv6, see

http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00840100/c00840100.pdf. This document

discusses how name resolution plays a fundamental role in Dual-Stack transition methods. Using the name resolution algorithm in Windows, the document goes through various network environments and studies how the introduction of routable IPv6 addresses will affect network applications. It also discusses DHCPv6, SLAAC and the impact to DNS, and makes some recommendations.

Connect the printer to the Internet

To connect to the Internet, go to the front panel and press , then Connectivity > Connectivity wizard.

The connectivity wizard also checks that the printer’s firmware is up to date. Normally you need to run the wizard only once, when first setting up the printer.

An Internet connection is needed for various printer functions described in this guide, such as the Embedded Web Server.

RIP software installation

Install the RIP software by following the instructions provided with the software.

Advanced network configuration

You will probably not need to read this section, but the information is provided as it may be useful in some cases.

The printer provides a single RJ-45 connector port for a network connection. In order to meet Class B limits, the use of shielded I/O cables is required.

The embedded Jetdirect print server supports connection to IEEE 802.3 10Base-T Ethernet, IEEE 802.3u 100Base-TX Fast Ethernet and 802.3ab 1000Base-T Gigabit Ethernet compliant networks. When connected and powered on, the printer auto-negotiates with your network to operate with a link speed of 10, 100, or 1000 Mbps, and to communicate using full- or half-duplex mode. However, you can manually configure the

ENWW Advanced network configuration 25

link using the printer's front panel, or through other configuration tools once network communication is established.

The printer can support multiple network protocols simultaneously, including TCP/IPv4 and TCP/IPv6. For security, it includes features to control IP traffic to and from the printer.

Verify correct operation

1. Print an IO Configuration page to check for status messages.

2. In the upper section of the IO Configuration page, look for the status message I/O Card Ready.

3. If I/O Card Ready appears, the print server is operating properly. Proceed to the next section.

If a message other than I/O Card Ready appears, try the following:

a. Turn the printer off and then on again to re-initialize the print server.

b. Check that the status indicator lights (LEDs) are providing proper status.

NOTE: See Troubleshooting on page 26 for link configuration and troubleshooting information.

See the HP Jetdirect Print Servers Administrator’s Guide for your print server model to interpret and troubleshoot other messages.

Preconfigure network settings if required

If your network requires that you configure network settings before you add the printer to your network systems, you can do so now.

However, in most cases, you can skip this section. Instead, you can proceed directly to the next section to install the printer on your network computer systems. The network installation software will allow you to configure basic network settings and add the printer to your system configuration.

Tools for preconfiguration

The following tools can be used to preconfigure your network settings.

●

The front panel

●

The Embedded Web Server

●

You can use an advanced configuration method, such as BootP, DHCP, Telnet, or the arp and ping commands. For instructions, see the HP Jetdirect Print Servers Administrator’s Guide for your print server model.

After the printer is configured with network settings, the configuration values are saved and maintained even after it is turned off and on again.

Troubleshooting

IO Configuration page

The IO Configuration page provides comprehensive print server status. It is an important diagnostic tool, especially if network communications are not available. For a description of messages that may appear on the IO Configuration page, see the HP Jetdirect Print Servers Administrator’s Guide for your print server model.

LEDs

The printer has status lights (LEDs) that indicate the link status and network activity.

26 Chapter 1 Introduction ENWW

Turn the printer on and off

To turn on the printer, ensure that the power switch at the rear of the printer is turned on, then press the power button beside the front panel.

You can leave the printer on without wasting energy. Leaving it on improves response time. When the printer has not been used for a certain period of time, it saves power by going into sleep mode. Pressing the power button returns it to active mode, and it can resume printing immediately.

To tun off the printer, the normal and recommended method is to press the power button.

When you turn off the printer this way, the printheads are automatically stored with the maintenance cartridge, which prevents them from drying out.

However, if you plan to leave the printer turned off for a long period of time, you are recommended to turn it off using the power button, and then also turn off the power switch at the rear.

To turn it back on later, use the power switch at the rear. If the printer does not start automatically, press the power button.

32 Chapter 1 Introduction ENWW

When the printer is turned on, it takes 2–3 minutes to initialize itself.

Restart the printer

In some circumstances you may be advised to restart the printer.

1. Turn off the printer by pressing the power button and then turning off the power switch at the rear of

the printer.

2. Wait for at least 10 seconds.

3. Turn on the power switch at the rear of the printer.

4. If the front panel does not activate, press the power button.

Overview

You can print on a wide variety of printing materials, all of which are referred to in this guide as substrates.

Substrate tips

Choosing the correct substrate for your needs is an essential step in ensuring good print quality.

Here are some tips about substrate usage.

●

Using the take-up reel with some substrates may give the printer better control of the substrate and is likely to improve print quality. See

●

Allow all substrates to adapt to room conditions, out of the packaging, for 24 hours before using them for printing.

●

Handle film and photo substrates by the edges, or wear cotton gloves. Skin oils can be transferred to the substrate, leaving fingerprint marks.

●

Keep the substrate tightly wound on the roll throughout the loading and unloading procedures. To make sure that the roll stays tightly wound, consider using tape to stick the leading edge of the roll to the core just before removing the roll from the printer. You can keep the roll taped during storage. If the roll starts to unwind, it can become difficult to handle.

NOTE: The use of tape to stick the leading edge of the roll to the core is especially important for heavy

substrates, because the inherent stiffness of the substrate can cause it to loosen and unwind from the core.

The take-up reel (accessory) on page 55.

●

Print quality could be impaired if you use a substrate that is unsuitable for your image.

●

Make sure that the appropriate print-quality setting is selected in the RIP.

●

Whenever you load a roll, the front panel prompts you to specify the substrate type that you are loading. For good print quality, it is essential to specify this correctly. Check that the substrate name is the same in the front panel and in the RIP.

If the names are not the same, press on the front panel, then Substrate > Change loaded

substrate

●

Do not pull the printed substrate while the printer is printing: this can cause severe print-quality defects.

; or change the substrate in the RIP.

ENWW Overview 37

●

When printing a series of jobs, do not let the printed substrate obstruct the output path: this can cause severe print-quality defects.

●

For more substrate tips, see Load a roll into the printer on page 46 and Assisted manual load

on page 49.

CAUTION: Removing the substrate from the printer manually without using the front panel could damage

the printer. Do this only when necessary to clear a substrate jam.

Porous substrates

The printer is not designed to be used with porous substrates, and could be damaged by them, requiring a service repair not covered by your warranty.

To check the porosity of your substrate, proceed as follows.

1. If the printer has any substrate loaded, unload it.

2. Cut a piece of self-adhesive vinyl white gloss 15 × 50 mm (0.6 × 2 in) in size.

ENWW Porous substrates 41

3. Stick it to the platen as shown.

4. Load the substrate that you want to check.

5. Open your RIP software.

6. Download the test file from inside the printer: http://printerIP/hp/device/webAccess/images/

Ink_trespassing_check.pdf, where printerIP is the IP address of your printer.

7. Print the test file using the number of passes and substrate preset that you intend to use in future with

this substrate (or a similar profile in terms of ink limit).

8. Unload the substrate.

9. Remove the strip of self-adhesive vinyl from the platen.

10. Look at the self-adhesive vinyl you have taken from the platen.

●

If the strip is completely white (has no ink on it), the tested substrate is non-porous and can be used for printing as described in this guide.

●

If there some ink on the strip, the tested substrate is porous and should not be used.

11. Clean the platen: see Clean the platen on page 125.

Load a roll onto the spindle

TIP: As an alternative to the description here, you can see an animation of this procedure in the front panel:

press , then Substrate > Substrate load > Learn how to load spindle.

1. Make sure that the printer wheels are locked (the brake lever is pressed down) to prevent the printer

from moving.

42 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

2. Lift the spindle lock lever to disengage the spindle.

3. Remove the spindle from the printer.

CAUTION: Do not insert your fingers into the spindle supports.

The spindle has a stop at each end to keep the roll in position. Remove the blue stop at the left end to mount a new roll (the stop at the other end of a 3 in (76 mm) diameter spindle can also be removed, if you wish). The stop slides along the spindle to hold rolls of different widths.

NOTE: If you have a 2 in (51 mm) spindle, you can use the 3-in adaptor.

4. Unlock the blue stop.

ENWW Load a roll onto the spindle 43

5. Remove the stop from the left end of the spindle.

6. Place the roll onto the loading table.

7. Slide the spindle into the roll.

44 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

8. The 51 mm (2 in) diameter spindle has only one position for the right stop. There are blue lines on the

loading table corresponding to two positions, but when using this spindle you can use only the outer position.

9. Put the blue stop on to the upper end of the spindle, and push it towards the end of the roll.

10. Lock the blue stop when it is in contact with the substrate.

11. Insert the spindle carefully into the printer.

WARNING! Avoid trapping your fingers between the spindle and the spindle supports.

Risk of trapped fingers

For more safety information, please see Safety precautions on page 3

ENWW Load a roll onto the spindle 45

CAUTION: Ensure that the sliders in the loading table are under the left hub, otherwise the spindle will

not enter correctly into the left spindle support, and could fall on the floor.

If you regularly use different substrates, you can change rolls more quickly if you pre-load rolls of different substrates on different spindles. Extra spindles are available for purchase.

Load a roll into the printer

To start this procedure, you need to have a roll loaded on the spindle. See Load a roll onto the spindle

on page 42.

The normal minimum substrate width is 23 inches (584 mm). To load substrates down to a minimum width of

10 inches (254 mm), go to the front panel and press , then Substrate > Substrate handling options >

Enable narrow substrate. With this option, print quality is not guaranteed.

TIP: When loading very thin or very thick substrates, or substrates with a tendency to curl, you should

follow the manual loading procedure to reduce the risk of substrate jams and printhead crashes; see Assisted

manual load on page 49.

At the printer's front panel, press , then Load.

Alternatively, press , then Substrate load > Load roll.

46 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

2. The load configuration screen appears.

●

Skew acceptance: The available values are between 1 and 5, default 3. The printer warns you if the skew is over the limit you have set, but you can still choose to continue loading.

●

Length tracking: If you check the box and give the length of your roll, the printer reduces the spare paper when printing and tells you the remaining length. See Substrate length tracking

on page 62.

●

Assisted manual load. See Assisted manual load on page 49.

●

Use edge holders. See The edge holders on page 51.

When you have made your choices, instructions are displayed.

3. Carefully insert the leading edge of the substrate above the smooth black roller, making sure the

substrate remains taut during the process. Avoid rewinding the substrate manually, unless the printer asks you to do so.

WARNING! Take care not to insert your fingers inside the printer's substrate path.

The printer beeps when it detects and accepts the leading edge of the substrate.

ENWW Load a roll into the printer 47

4. Select the category and name of the substrate you are loading.

You can also search by favorites, or you can select None of these, I will choose it later: by accessing the substrate library after completing the loading procedure. See Substrate presets on page 71.

NOTE: You should select the same substrate name that you are using in your RIP software.

5. The printer checks the substrate in various ways and may ask you to correct problems with skew or

tension.

6. Wait until the substrate emerges from the printer, as shown below.

WARNING! Take care not to touch the curing zone or the platen, which may be hot.

Risk of burns

For more safety information, please see Safety precautions on page 3

NOTE: If you have an unexpected problem at any stage of the substrate loading procedure, see The

substrate cannot be loaded successfully on page 63.

7. If you are loading transparent substrate without opaque borders, you are asked to enter the width of

the substrate and the distance of the right edge from the printer's side plate (as indicated by the ruler on the front of the curing module).

48 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

8. The printer indicates that it is ready for printing.

Take care not to cover the top fans.

For instructions on how to use the take-up reel, see The take-up reel (accessory) on page 55.

Assisted manual load

The assisted manual load procedure should be used in the following cases:

●

The substrate is unusually thin or unusually thick.

●

The substrate has ragged edges.

●

The substrate tends to curl at the edges.

●

The printing side of the substrate faces outwards.

In other cases, you are recommended to use the normal loading procedure. See Load a roll into the printer

on page 46.

To start the assisted manual load procedure, you need to have a roll loaded on the spindle. See Load a roll

onto the spindle on page 42.

The normal minimum substrate width is 23 inches (584 mm). To load substrates down to a minimum width of

10 inches (254 mm), go to the front panel and press , then Substrate > Substrate handling options >

Enable narrow substrate. With this option, print quality is not guaranteed.

1. Start the substrate loading procedure as usual (see Load a roll into the printer on page 46), and make

sure to check the Assisted manual load box in the load configuration screen.

ENWW Assisted manual load 49

You can alternatively begin at step 2, in which case the load configuration screen will appear with this checkbox checked after you lift the pinch lever. Press Continue before taking the next step.

2. Lift the substrate pinch lever as far up as it will go.

3. Carefully insert the leading edge of the substrate above the smooth black roller, making sure the

substrate remains taut during the process. Avoid rewinding the substrate manually, unless the printer asks you to do so.

4. Continue to feed the substrate until it reaches the printing platen. Open the window to help pull the

substrate through, and keep feeding the substrate at least until the leading edge is at the same height as the substrate roll. Align the right edge of the substrate with the right edge of the roll.

WARNING! Do not touch the printer's curing enclosure. Even after you have opened the window latch,

which disconnects the power to the curing modules, the internal surfaces could be hot. Also beware of getting your fingers trapped in the substrate path.

Risk of burns Risk of trapped fingers

For more safety information, please see Safety precautions on page 3

TIP: If the substrate you are using tends to curl, keep feeding the substrate until the edge is out of the

printer. You are also recommended to use the take-up reel, if you have purchased it as an accessory.

50 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

5. Once the substrate is correctly fed into the printer, pull down the substrate pinch lever as far as it will

go.

6. Select the category and name of the substrate you are loading.

The rest of the assisted load procedure is the same as in the normal load procedure. See Load a roll into the

printer on page 46.

The edge holders

The edge holders are designed to prevent the edges of the substrate from rising while printing is in progress. They are not normally necessary. When not in use, they should be stored inside the printer, to the left and right respectively, to avoid substrate jams. It is also a good idea to store the edge holders when no substrate is loaded, in case you later forget and leave them installed by mistake.

NOTE: The edge holders extend 7 mm over the edge of the substrate. You should set a minimum left and

right margin of 7 mm (0.3 in) in the RIP when using edge holders, otherwise the printer could try to print on the edge holders.

If you choose to use them, you should move them into position when prompted by the front panel (this prompt appears when the Use edge holders checkbox has been checked). Open the window, place the edge holders, then close the window.

The edge holders should be placed on the platen so that they slightly overlap the left and right edges of the substrate. There are marks on the printer to show where to place them.

The edge holders for each printer model are the same, but they are installed in different ways.

WARNING! Avoid moving parts. Handle fragile parts with care. You are recommended to wear gloves.

ENWW The edge holders 51

Place edge holders

1. There is a hole on the left for the edge holders. Insert an edge holder vertically into the hole.

2. Slide the edge holder into its correct position.

Moving part Fragile Wear gloves

For more safety information, please see Safety precautions on page 3

3. Repeat with the other edge holder.

Align the substrate

When the substrate has been loaded, align it with the white line on the edge holder. Misalignment could result in a substrate jam, or damage to the substrate or to the printheads.

52 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

Load a cut sheet into the printer

The printer is designed to be used with rolls of substrate. It is possible to load cut sheets into the printer, but print quality cannot be guaranteed, and you may have some difficulty in avoiding skew.

●

The sheet should be at least 1067 mm (42 in) long.

●

Load the sheet by following the normal roll loading procedure (automatic or manual, depending on the substrate).

●

During the loading procedure, the printer tries to detect the winding direction of the roll by turning the spindle in both directions. When the substrate is not attached to the spindle, the following message appears.

●

A cut sheet is likely to be loaded with excessive skew, and the printer may not be able to correct it automatically. If the skew as measured by the printer exceeds 3 mm/m, you are recommended to reload the sheet. However, if the skew is tolerable, you can consider skipping the automatic skew correction. To do so, when prompted, choose Continue with current skew.

How to cut substrate

To cut the substrate, open the window and cut the substrate using the slot indicated below. Ensure that the substrate is under tension while cutting.

CAUTION: Use a safety cutter.

ENWW Load a cut sheet into the printer 53

CAUTION: Do not place your hand below the cutter. Be very careful not to cut yourself.

Unload a roll from the printer

1. If you used the take-up reel during printing, unload the printed roll from the take-up reel. See Unload

the take-up reel on page 61.

On the printer's front panel, press , then Unload.

Alternatively, you can press , then Substrate > Unload substrate.

3. If the printer has been tracking the length of the substrate, the front panel displays the remaining

length so that you can note it for future reference. See Substrate length tracking on page 62.

Press OK to continue.

4. When the printer has rewound the roll, lift the spindle lock lever.

5. Remove the spindle from the printer, pulling out the right end on the right side of the printer first.

WARNING! Do not insert your fingers into the spindle supports while removing the spindle.

Risk of trapped fingers

For more safety information, please see Safety precautions on page 3

54 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

The take-up reel (accessory)

The tension bar

When in use, the take-up reel requires a dangling loop of substrate weighed down by a tension bar. The tension bar can be moved with the take-up reel buttons or by using the Move paper or Rewind paper options in the front panel.

Load a roll onto the take-up reel

NOTE: Take-up reels with 51 mm (2 in) or 76 mm (3 in) diameter can be used.

On the printer's front panel, press , then Take-up reel.

Instructions are displayed on the screen; slide your finger laterally across the front panel to follow the instructions to the end.

2. If you decide to load the take-up reel during printing, familiarize yourself with the procedural steps

before pressing the Enable button. Loading the take-up reel during printing requires you to complete the procedure while the printer is feeding and printing substrate. Loading the take-up reel during printing saves approximately 1.5 m (4.9 ft) of substrate.

TIP: You are recommended to keep the take-up reel winding-direction switch in the off position (see

Unload the take-up reel on page 61) to avoid unwanted movements when loading the take-up reel

while printing. Once you have the leading edge of the substrate attached to the core, and the substrate is straight, switch the winding-direction switch to position 1 or 2, as you prefer. Setting 1 winds the substrate so that the printed image faces in, setting 2 winds the substrate so that the printed image faces out.

The following steps assume that you have decided to load immediately. If you decide to load later, during printing, you must complete the same operations without guidance from the front panel.

ENWW The take-up reel (accessory) 55

3. For easier access to the take-up reel, lift the loading table into its upright position.

4. Unlock the take-up reel by pushing its lever to the uppermost position.

5. Remove the take-up reel.

6. Load the core onto the take-up reel. The core should be at least as wide as the substrate.

7. Load the take-up reel into the printer by pushing firmly on both ends.

56 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

WARNING! Take care not to get your fingers trapped.

Risk of trapped fingers

For more safety information, please see Safety precautions on page 3

8. Advance the substrate by pressing the Move substrate button on the front panel. Make sure that the

substrate passes in front of the loading table.

9. Pull down the center of the substrate's leading edge to straighten the substrate. Do not attempt to pull

more substrate out of the printer.

NOTE: If you are loading the take-up reel during printing, you do not need to pull the substrate taut.

Tape the substrate to the core when an adequate length of substrate has fed from the printer after printing begins.

WARNING! Do not touch the printer's curing enclosure, which could be hot.

10. Adjust the position of the core on the take-up reel so that it is aligned with the substrate.

11. Tape the leading edge of the substrate to the core in the center, then at each side. Make sure that the

substrate is straight.

NOTE: Depending on whether you want to print the images facing in or out, place the tape

accordingly. See below.

12. Press the button on the front panel to advance the substrate, creating a loop.

58 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

13. Press the blue arrow on the take-up reel motor to rotate the reel one full turn. This will help to support

the weight of the tension bar.

14. Press the button on the front panel to advance the substrate again.

15. Gently lower the loading table, to avoid wrinkles and improve winding.

ENWW The take-up reel (accessory) 59

16. Carefully insert the tension bar. This is essential: the take-up reel will not function correctly without it.

17. Fit the tension bar into the supports at either side.

19. Press the Enable button on the front panel.

20. The following image shows how the printer looks when it is operating. As substrate is fed from the

printer, it drops down to the tension bar, over the diverter, then down again to the take-up reel.

NOTE: When the take-up reel is in use, the substrate is not automatically cut after each print.

The printer allows you to move the substrate to facilitate cutting.

2. Switch the winding-direction switch to the off position. The switch is in the off position when it is

centered (in other words, when the switch is neither in position 1 nor position 2).

3. To remove the tension bar, first lift the support, then press the lever.

4. Use the winding button on the take-up reel motor to wind the excess substrate around the take-up reel.

5. Cut the substrate with scissors.

6. While holding the substrate, use the winding button on the take-up reel motor to wind the remainder of

the substrate around the take-up reel.

7. Unlock the take-up reel by pushing its lever to the uppermost position.

8. Remove the take-up reel from the printer, pulling out the end on the right side of the printer first.

9. To remove the roll from the printer after you have unloaded the take-up reel, see Unload a roll from the

printer on page 54.

ENWW The take-up reel (accessory) 61

View information about the substrate

On the front panel's home screen, press .

The following information appears on the front panel, if any substrate is loaded:

●

The substrate type

●

The substrate name

●

The substrate width in millimeters (estimated by the printer)

●

The remaining length of the substrate, if known

●

The printing zone

●

The take-up reel status

●

The color calibration status

If no substrate is loaded, the message Out of substrate appears.

The same information appears on the Embedded Web Server's Supplies page.

Change substrate width and right edge position

If the substrate edges are not correctly found by the printer, they can be changed from the front panel by

pressing , then Substrate > Substrate handling options > Substrate width or Right edge position.

TIP: Bear in mind that automatic edge detection will not be attempted again until the next substrate load.

Substrate length tracking

The substrate length tracking feature enables you to keep track of how much substrate remains on the roll.

1. When the roll is first loaded onto the printer, you have the option (in the Load Configuration screen) to

enter the length of substrate on the roll. The amount of substrate that is subsequently used is then tracked.

2. When the substrate is unloaded, the front panel displays the amount remaining so that you can note it

for future reference.

The remaining length of substrate is always displayed in the Substrate area of the front panel. This information may also be displayed in your RIP.

Bypass job start safety

The job start safety mode is activated by default so that the leading edge of the substrate does not crash under the curing system.

62 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

If you print with the substrate hanging from the front of the printer, or using the take-up reel, you may want

to deactivate this option to improve throughput. To do that, press , then Substrate > Substrate

handling options

> Bypass job start safety.

Store the substrate

The following are tips for storing substrate:

●

Always keep unused rolls wrapped in the plastic wrap to prevent discoloration and dust accumulation. Rewrap partially used rolls if they are not being used.

●

Do not stack rolls.

●

Allow all substrates to adapt to room conditions out of the packaging for 24 hours before printing.

●

Handle film and glossy substrates by the edges or wear cotton gloves. Skin oils can be transferred to the substrate, leaving fingerprint marks.

●

Keep the substrate tightly wound on the roll throughout the loading and unloading procedures. If the roll starts to unwind, it can become difficult to handle.

The substrate cannot be loaded successfully

Here are some suggestions to try if you cannot load the substrate successfully.

●

Reread the loading instructions, and make sure that you are following them. See Handle the substrate

and troubleshoot substrate issues on page 36.

●

If automatic loading is unsuccessful, try assisted manual loading instead.

●

The substrate might be loaded at an angle (skewed or mislocated). Make sure that the right edge of the substrate is aligned with the roll on the input spindle.

●

The substrate might be crumpled or warped, or have irregular edges. See The substrate is deformed or

wrinkled on page 67.

●

If the substrate jams in the substrate path to the platen, the leading edge of the substrate might not be straight or clean. Remove the initial 2 cm (1 in) of substrate from the roll and try again. This might be necessary even with a new roll of substrate.

●

Make sure that the spindle is correctly inserted.

●

Make sure that the substrate is correctly loaded on the spindle.

●

Make sure that the substrate is wound tightly.

ENWW Store the substrate 63

The substrate is mispositioned

If you see the above display on the front panel, proceed as follows.

1. Lift the substrate lever.

2. Manually reposition the substrate on the platen.

3. Lower the substrate lever.

4. Repeat the above steps until the front panel displays the Ready message.

The substrate has jammed

When a jam occurs, the Possible substrate jam message usually appears in the front panel, with one of several error codes (see Front-panel error codes on page 137).

If you are trying to load a very thin or very thick substrate, or a textile, remember to follow the special procedure for loading such substrates..

Check the substrate path

This problem can occur when a roll has finished and the end of the roll is stuck to the cardboard core. If this has happened, cut the end of the roll away from the core. Then feed the substrate through the printer, and load a new roll.

Otherwise:

1. Turn off the printer at the front panel, then also switch off the power switch at the rear.

64 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

2. Open the printer window.

3. Cut the substrate where it enters the printer, and rewind the input roll.

4. Try to move the printhead carriage out of the way.

5. Lift the substrate pinch lever as far up as it will go.

6. Carefully remove as much as possible of the jammed substrate from the top of the printer. Cut the

substrate if necessary.

ENWW The substrate has jammed 65

CAUTION: Try to avoid pulling the substrate out through the input path, because this reverses the

normal direction of movement, and could damage printer parts.

WARNING! Do not touch the printer's curing enclosure, which could be hot.

Risk of burns

For more safety information, please see Safety precautions on page 3

7. Lower the substrate pinch lever.

8. Make sure that there are no pieces of substrate left in the printer. In particular, check in and under the

curing module, and in the substrate path.

9. Close the window.

10. Turn on the printer.

11. Reload the roll.

12. If some substrate continues to cause an obstruction within the printer, it can often be cleared by loading

a rigid substrate type into the printer.

13. If you find that you have print-quality problems after a jam, try realigning the printheads. See Align the

printheads on page 106.

Avoiding substrate jams while printing

Substrate jams may be caused by loading the substrate with too much skew: do not ignore the warning message that appears during the loading procedure in this case.

They may also be caused by not enough vacuum suction in the printing zone. If you decide to increase the suction, do not exceed the following limits: 20 mmH2O for banners, 35 mmH2O for vinyl, and 50 mmH2O for

other substrate families.

If you experience jams only at the beginning of a print, try the following suggestions.

66 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

●

Go to the front panel and press , then Substrate handling options > Extra bottom margin and

Extra top margin. Set both margins to 100 mm. If that is not enough, try higher values.

●

Increase the vacuum level in steps of 10 mmH2O. Do not exceed the following limits: 20 mmH2O for banners, 45 mmH

Consider reducing the vacuum percentage at the front of the print zone for thin substrates.

●

Increase the number of passes.

●

Make sure that the substrate is stored in the same room in which the printer is located.

●

Try using the substrate edge holders.

O for vinyl, and 60 mmH2O for other substrate families.

The substrate is deformed or wrinkled

If your substrate is deformed or wrinkled by the curing process, change the temperature settings before printing the next job, and advance the substrate, using the Move substrate option in the front panel's Substrate menu, so that the next job will be printed on undamaged substrate.

If the problem appears only at the beginning of the print, try the following suggestions.

●

Go to the front panel and press , then Substrate handling options > Extra bottom margin and

Extra top margin. Set both margins to 100 mm. If that is not enough, try higher values.

●

Increase the vacuum level in steps of 10 mmH2O. Do not exceed the following limits: 20 mmH2O for banners, 45 mmH2O for vinyl, and 60 mmH2O for other substrate families.

●

Increase the number of passes.

●

Make sure that the substrate is stored in the same room in which the printer is located.

The substrate has shrunk or expanded

During the printing process, some substrates may shrink, while others may expand. If this happens, the dimensions of the print will not be correct.

As a general rule, you can expect the following percentages of shrinkage:

●

Banner: less than 2%

●

Self-adhesive vinyl: less than 0.5%

●

Backlit: less than 0.5%

●

Paper: less than 0.5%

●

PP & PE synthetics: less than 1%

The framing problem may be solved by printing a sample and adjusting the size of the image in the RIP. You may reuse this value for all your future prints with the same substrate, although special care must be taken when using banners, as the shrinkage may vary up to 1% depending on the amount of ink used in the print.

You can expect the following variations from one print to another:

●

Banner: less than 0.3%

●

Self-adhesive vinyl: less than 0.1%

●

Backlit: less than 0.05%

ENWW The substrate is deformed or wrinkled 67

●

Paper: less than 0.1%

●

PP & PE synthetics: less than 0.4%

You are recommended to tile together areas with similar amounts of ink. If this is not possible, print the areas with different amounts of ink as different jobs and modify the length of the job with less ink in the RIP to match its size with the job with high ink content.

Some RIPs may provide a scaling option that allows you to compensate easily for substrate shrinkage or expansion; see your RIP documentation.

The substrate has bow deformation

The following substrates may suffer from bow deformation during printing, as a result of which the print will appear curved.

●

Self-adhesive vinyl substrates (some specific calendared vinyls only)

●

Cellulose-based poster papers with no backing nor coating

This deformation may be particularly noticeable in the following applications.

●

Printing images that will later be cut automatically or manually. When there is bow deformation, cutters that are aligned on the sides may lose alignment in the center.

●

Poster printing, if the poster is framed or mounted on a straight surface.

The example below shows an original image, the substrate suffering from bow deformation, and the resulting print, also suffering from bow deformation.

You can compensate for this effect and restore the original shape of your image: select a correction value from −6 to +6 in your RIP or in the substrate library. To apply the correction in your RIP, please refer to your RIP documentation.

The chosen value should represent the vertical distance that the centre of the substrate has moved with respect to the left and right edges. If the deformation moves the center of the substrate in the direction of substrate advance, the correction value should be negative; if in the reverse direction, the correction value should be positive. In practice, the required correction value is normally negative.

TIP: You can use the diagnostic image provided in http://IPaddress/hp/device/webAccess/diagnostic/

StraightnessOptimizationPlot.pdf (where IPaddress is the IP address of your printer) to help you to

determine the correct value to apply.

Take-up reel substrate jam

Cut the substrate as close as possible to the printer window, then remove the roll.

If the problem remains after removing the substrate jam, unload the take-up reel from the front panel and load it again.

68 Chapter 3 Handle the substrate and troubleshoot substrate issues ENWW

Take-up reel does not wind

Predictably, if the take-up reel is not winding as anticipated, the printed output is likely to end up on the floor. If the printer recognizes a problem with the take-up reel, it interrupts the print job until the issue is corrected. If the printer does not recognize a problem, the job continues to print. The following table highlights possible issues and solutions.

Substrate presets

Each substrate type has its own characteristics. To obtain the best print quality, the printer has to adapt its printing parameters to each different substrate type. For example, some may need more ink and some may require higher temperatures for curing. A specification of the correct printing parameters for a particular substrate type is called a substrate preset.

The substrate preset contains a color profile in International Color Consortium (ICC) format, which describes the color characteristics of the combination of printer, inks, and substrate. It also contains information about other parameters (such as curing temperature, vacuum pressure, and substrate-advance compensation) that are not directly related to color. Substrate presets (also known as Open Media System or OMES packages) are installed in the printer, and automatically copied to supported RIP software whenever it is connected to the printer.

The printer comes with substrate presets for the most commonly used generic and specific substrates. If you load a substrate for which no specific preset is available in the printer, you have various options:

●

Use the Online search function on the front panel or the HP Media Locator on the Web to browse, search, and download a specific preset for your substrate.

●

Download a preset from the RIP vendor's website, or from the substrate vendor’s website.

●

Use a generic preset designed for your substrate category, even though it is not fine-tuned for the specific substrate type. Bear in mind that generic substrate settings cannot be modified; instead, the preset can be cloned and then modified.

●

Clone (copy) a preset for a similar substrate, and edit it as necessary.

●

Create a new preset, starting from scratch, using the Add new button.

If you can find a ready-made preset for your specific substrate, you are recommended to use it.

Online search

You can search online for a substrate preset by using the Online search function within the Substrate Library front-panel menu. The printer connects to the HP Media Locator database on the Internet and allows you to search all available substrate presets for your particular printer model, including HP and third-party substrate brands. Hundreds of different substrate presets may be available, and the database of substrate presets is continuously updated and expanded. You will always get the most up-to-date content in this way.

ENWW Substrate presets 71

When the printer is connected to the database (this may take a few seconds), a list of all available substrate presets for your printer model is displayed. You can browse the list by scrolling it, and get details on any preset by pressing its name. Besides browsing, there are two additional ways to look for presets: free-text search and filters.

●

Free-text search allows you to type in any text using an on-screen virtual keyboard; all substrate presets containing that text in any part of their name or description will be displayed. For example, if you search for "vinyl" then substrate descriptions such as "self-adhesive vinyl" or "vinyl banner" will match and be displayed. The search is case-insensitive; that is, "vinyl" will match both "vinyl" and "Vinyl".

●

Filters are available for brand, type, sub-type, and application. When a value is selected for a given filter, only the matching substrate presets will be displayed. For example, if you select "HP" from the brand filter, only HP substrate presets will be displayed. The effect of using more than one filter is to narrow the search to the combination of the filter settings. For example, if you choose "HP" from the brand filter and "Self-Adhesive Vinyl" from the Type filter, only substrate presets for HP Self-Adhesive Vinyl substrates are displayed.

Once you have located the substrate preset of your choice, pressing its download icon will queue it for automatic download and installation in the background. You can select as many substrate presets as you want for download and installation (they will be processed in the order that they were selected). You can return to another part of the Media Manager or another front panel screen at any time after queuing presets for download, and this will not interrupt the download and installation process.

Once a substrate preset has been downloaded in the background, it is checked and installed on the printer's hard disk. During checking and installation, a full-screen message is shown on the front panel. This message disappears when checking and installation is complete.

The new substrate preset now appears in the Substrate Library together with all previously installed and factory-provided presets, and is ready for use.

Some supported RIPs may implement a similar online substrate-preset search function accessing the same HP Media Locator database. Whether you use the printer's front panel search or RIP-based search does not matter: the end result is the same. Supported RIP software synchronizes its substrate preset list with the printer, so that printer and RIP will always have the same list.

72 Chapter 4 Substrate settings ENWW

HP Media Locator

The HP Media Locator database of substrate presets can also be accessed from a Web browser by visiting

http://www.hp.com/go/mediasolutionslocator. This provides access to the database for different regions,

printer models, applications, suppliers, substrate types, and so on.

When you have located the substrate preset of your choice, you can download it to your computer. To install the preset into the printer with which you want to use it, use the printer's Embedded Web Server. Navigate to the Setup > Substrate presets management > Import screen.

Click Browse to browse to the substrate preset file that you have previously downloaded to your computer, then click Update to install the preset in your printer.

The Embedded Web Server also allows you to export substrate presets from your printer for use with another printer of the same model. When importing a previously exported substrate preset, you may see a message warning you that the package is not signed (only packages downloaded from the HP Media Locator internet database are digitally signed, as a form of authentication); you can then ignore the warning and continue with the installation, or abort the installation.

Generic presets

Generic presets are each designed for a whole substrate category, rather than for a particular substrate type. They cannot be edited, erased, saved, color-calibrated or ICC profiled; but they can be cloned. Therefore, if you would like to modify a generic preset in any way, you should first clone it and then work on the clone, which is fully editable.

The printer provides generic presets for the supported substrate categories: see Supported substrate

categories on page 38.

ENWW HP Media Locator 73

Clone a substrate preset

You may wish to clone and edit a preset for various reasons:

●

To assign a name of your own choice to the preset

●

To adjust the preset to the precise characteristics of your substrate

●

To adjust the preset to your intended use of the substrate, which may range from highest-quality printing to fast production output.

To clone a substrate preset, follow these steps:

1. Select a preset in the Substrate Library.

2. Click Clone to clone the preset, and enter a name for the new preset.

Modify a substrate preset

You can modify a preset by pressing Modify.

Then press beside the print mode that you want to modify; or click Add new print mode. You can delete or change the name of any print mode; although you should keep at least one print mode.

NOTE: You can define up to six print modes.

74 Chapter 4 Substrate settings ENWW

NOTE: The number of passes in an existing print mode cannot be changed. If you want to change the

number of passes, create a new print mode.

NOTE: You are not allowed to create two print modes with the same number of passes and the same color

saturation.

To change the values, you must print a test plot. Check it and choose the number in the pull-down colorsaturation menu that matches your preferences in terms of curing and drying. If none of the options are good enough, try changing the temperature and reprint. You can also change the substrate advance settings.

Add a new substrate

If you cannot find a ready-made preset for your substrate, and prefer not to use a generic preset or edit an existing preset, you can make your own preset from scratch.

The Add New Substrate wizard guides you to work out the best settings for your substrate. It first requests some information about the substrate and your intended use of it, then prints some test prints and asks you to evaluate them. From this information, it creates the new preset.

1. Ensure that the printer is in the Ready state.

2. Stop the job queue.

3. Load your new substrate, selecting the most similar substrate when asked to do so; or select None of

these.

4. When the substrate has been loaded, go to the Substrate Library on the front panel, and choose the

substrate category in the left column of the Substrate Library screen (PVC BANNER in this example), then click + New PVC banner at the top of the right column. Your new preset will be based on a generic preset; If there are multiple generic presets in that category, the front panel asks you to choose one of them.

ENWW Add a new substrate 75

5. The following screen is displayed:

6. Press the blue button to produce the ink drying and color saturation test print; then continue adjusting

the settings and printing again until you are satisfied with the result.

NOTE: You can omit this step if you already know the settings that you want to use.

7. If you cannot reach a satisfactory result, you may want to press Advanced settings and try adjusting

those settings, which are intended for people who understand their implications.

To go back to the previous screen, press .

●

Straightness or bow compensation: Allows you to compensate for barrel-shaped substrate deformation. The value represents the distance that the centre of the substrate has moved with respect to the left and right edges. See The substrate has bow deformation on page 68.

●

Latex optimizer level: If you have bleed or coalescence, you can increase the optimizer level until you see a significant impact on gloss or color saturation.

●

Vacuum printing: Sets the vacuum value in the print zone to hold the substrate flat. Increase if the substratre suffers from crashes or smears, decrease if you see banding or graininess.

●

Advance factor: Allows you to increase or decrease the substrate advance in each carriage pass.

●

Inter-pass delay offset: The time delay between passes to allow for smoother drying. Increase the delay if you have seen banding on your prints.

●

Input tension: Substrate rewinder tension, increase in case of wrinkled substrate in the print .zone

8. When you have finished, press Continue to perform color calibration.

9. Enter your substrate name and click Start color calibration. See Color calibration on page 80.

10. After the automatic color calibration process has completed, we recommend using the generic ICC

profile; alternatively, you can choose to create a new profile or to copy a profile already assigned to a different print mode for this substrate (if there are any such profiles). The Create ICC profile button is disabled until color calibration is complete. See ICC profiles on page 82.

Change settings while printing

You can use the front panel to adjust the following settings while printing.

●

To change temperature, vacuum, inter-pass delay offset, and substrate-advance settings while printing, press Adjustments in the front panel’s print job screen, and choose the setting that you want to adjust. The changes that you make take effect immediately, but they are not saved: the next job will use the settings in the substrate preset as usual.

You can use the Save button to save settings, and the Reset button to restore the last saved settings.

NOTE: The Save button is not available for a generic or non-editable preset.

●

To change substrate advance calibration while printing (in case of banding): press Adjustments > Adjust substrate advance. The changes that you make take effect immediately, but they are not saved

for the next job. See also Substrate advance adjustment while printing on page 90.

ENWW Add a new substrate 77

To make permanent substrate-advance changes, use the RIP or front panel to modify the substrate preset.

Temperature profile

Many of the main and advanced substrate settings are related to temperature control, since this is a critical area for correct printing results with latex inks on a wide variety of substrates.

NOTE: There is a delay between making a change and seeing the results. See the front panel for actual

temperature checking.

NOTE: If you selected English units of measurement, you may notice some discrepancies, as the printer

works in Celsius and makes the conversion.

Select the number of passes

Increasing the number of passes will tend to improve the print quality but reduce the speed of printing.

Tips

●

2 to 4 passes provide lower print quality. Also, the color gamut will be slightly reduced, as total ink is limited to allow for curing.

●

1200 dpi print resolution is available in the 18-pass print mode only. If you intend to use it, ensure that you have a specific substrate preset for this print mode, because reusing others may not deliver the expected print quality.

●

For fast layout proofing on low-cost substrates, a low-ink 2-pass print mode has been enabled. It is recommended for paper-based substrates only, as curing may not work correctly for other substrate types in this mode.

Delete a substrate preset

You can delete substrate presets that you have added yourself, but not those that were supplied with the printer.

To do so, just press on the Substrate Library screen.

If you delete a preset, you will lose the reference to that substrate in the usage and accounting information. Instead of the name of the substrate, from that moment on you will see “Deleted substrate” in the usage and accounting information.

Faster printing

The obvious way to increase speed is to reduce the number of print passes, although this will tend to reduce print quality. Bear in mind the following considerations:

●

With fewer than 8 passes, you may see an increase in grain.

●

With fewer than 6 passes, the printer is more sensitive to substrate-advance problems, and you may need to reduce the ink quantity to improve print quality.

●

As you reduce the number of passes, the best curing temperature may be more difficult to find, and may be more sensitive to the ambient temperature and humidity.

Here is another suggestion for increasing the speed of printing:

●

Concatenating prints saves time, because one can be printed while another is being cured.

NOTE: Printing a single job for more than 2 hours can reduce the life of the printheads.

See also The printer seems slow on page 135.

ENWW Delete a substrate preset 79

Color calibration

The purpose of color calibration is to produce consistent colors with the specific printheads, inks, and substrate that you are using, and in your particular environmental conditions. After color calibration, you can expect to get very similar prints from your printer on different occasions.

Each substrate must be calibrated independently.

NOTE: Color calibration may not work correctly with non-HP ink.

There are cases in which a substrate may not be calibrated, in which cases the Calibrate and Reset options are not available:

●

The loaded substrate has a generic preset.

●

The loaded substrate has a preset that is not editable.

●

The loaded substrate is not suitable for color calibration.

Color calibration can be launched from the front panel, after pressing Modify preset, or when adding a new substrate.

In outline, the process consists of the following steps.

1. A calibration target is printed.

2. The colors on the calibration target are measured automatically.

3. The calibration target measurements are compared with an internal reference to calculate the

necessary calibration tables for consistent color printing on the substrate in use.

Factory default calibration tables are used whenever color calibration has never been run. The first time color calibration is run, the current printing color is taken as a reference, and factory default calibration tables continue to be used. This means that, after the first color calibration, the printed colors do not change, but are recorded as the reference for future calibrations. Subsequent color calibrations compare calibration target colors with the recorded reference, in order to calculate new calibration tables for consistent color printing on that particular substrate type.

From the front panel, you can delete the current calibration table, leaving the factory default calibration

table active, as if that particular substrate had never been calibrated. Press , then Image quality

maintenance

Color calibration as described above is not recommended for the following substrate types. It may be possible to calibrate some of these substrates by using an external color measurement device, driven by an external RIP.

●

Non-opaque substrates such as clear film and backlit substrates.

●

Substrates with an uneven surface, such as perforated vinyl and punched-window substrates.

Substrates suitable for color calibration include even-surfaced adhesive vinyls (neither punched nor perforated), PVC banners, and papers.

> Color calibration > Reset to factory.

Some substrates require the take-up reel for successful printing. However, the take-up reel may fail to cope with the backward movement of the substrate between the printing and scanning phases of color calibration. To perform color calibration when the take-up reel is in use, proceed as follows:

Ensure that the take-up reel is enabled. At the front panel, press , then Enable take-up reel.

2. Set the take-up reel's winding direction to the off position. See Unload the take-up reel on page 61.

80 Chapter 4 Substrate settings ENWW

3. Manually rewind the take-up reel, using the buttons on the take-up reel motor, to collect the substrate

and raise the tension bar until it almost touches the take-up reel.

4. Launch color calibration from the front panel.

5. When the color calibration has finished, you can reset the take-up reel’s winding direction.

Performing color calibration

The color calibration test chart is printed using a fixed print mode with a high number of passes and fixed curing and drying settings to ensure printing consistency. However, parameters affecting substrate advance should be fine-tuned, and printheads should be aligned, before starting color calibration for the first time.

To start color calibration of the loaded substrate from the front panel, select , then Image quality

maintenance > Color calibration > Calibrate. Color calibration can also be run while adding a new substrate (see Add a new substrate on page 75).

NOTE: Only substrates at least 61 cm (24 in) wide can be calibrated.

The calibration process is fully automatic and can be performed unattended after you have loaded substrate of the type you wish to calibrate. The process takes about 15 minutes and consists of the following steps:

1. The color calibration test chart is printed, which contains patches of different densities of each ink used

in your printer.

2. The test chart is scanned by the line sensor. If the scan cannot be completed successfully, a message is

displayed on the front panel; see Front-panel error codes on page 137.

3. From the measurements made by the line sensor, the printer calculates the necessary correction tables

to apply to your print jobs, for consistent color printing on that substrate type.

Calibration should be done in any of the following circumstances:

ENWW Color calibration 81

●

Whenever a new substrate type is introduced that has not yet been calibrated.

●

Whenever you notice excessive color differences between prints. Such color differences are mainly caused by aging and wear of the printheads, installing new printheads, and changes in substrate characteristics between one roll and another.

You can check the color calibration status of your substrate by pressing on the front panel.

●

Recommended status indicates that this substrate has never been calibrated. In this case, the factorydefault color tables will be applied to print jobs, as there is no reference state defined. After one or more color calibrations have been performed, pressing the Reset button returns the status to Recommended.

●

Done status indicates that a color calibration has been performed successfully at least once on this substrate, and therefore a color reference state is defined.

●

Obsolete status indicates that the last color calibration may be out of date. For instance, color calibration status is set to Obsolete whenever a printhead is replaced. The color reference state remains defined.

●

N/A indicates that this substrate cannot be color-calibrated.

NOTE: Generic substrates cannot be color-calibrated, although such substrates may be suitable for

color calibration. You can color-calibrate clones of most generic substrates.

TIP: If color calibration fails, it is worth trying again.

TIP: If the first color calibration of a new substrate fails, press the Reset button before trying again.

ICC profiles

Color calibration provides consistent colors, but consistent colors are not necessarily accurate. For instance, if your printer prints all colors as black, its colors may be consistent but they are not accurate.

In order to print accurate colors, it is necessary to convert the color values in your files to the color values that will produce the correct colors from your printer, your inks, your print mode, and your substrate. An ICC profile is a description of a printer, ink, print mode, and substrate combination that contains all the information needed for these color conversions.

These color conversions may be performed by your Raster Image Processor (RIP), if it offers that possibility; they are not performed by the printer. For further information on the use of ICC profiles, see the documentation for your application software and for your RIP.

In addition to the ICC profiles used for printing, you may wish to calibrate and profile your monitor (display device), so that the colors you see on the screen relate more closely to those that you see on your prints.

Most-common print-quality problems

ENWW 83

General printing advice

Use the following approach when you have any print-quality problem:

●

Make sure that the substrate type that you select on the front panel, and in your RIP software, is the same as the substrate type that is loaded in the printer. Make sure that the substrate type has been calibrated (including substrate-advance, printhead, and color calibration).

CAUTION: If you have the wrong substrate type selected, you could experience poor print quality and

incorrect colors, and perhaps even damage to the printheads.

●

Make sure that you are using the correct substrate preset for your substrate, with the correct ICC profile, or that you have followed the correct procedure to generate a new substrate preset (see Add a

new substrate on page 75).

●

Make sure that you are using appropriate print-quality settings in your RIP software.

●

Make sure that your environmental conditions (temperature, humidity) are in the recommended range. See Environmental specifications on page 145.

●

Make sure that your ink cartridges have not passed their expiration dates. See Maintain the ink

cartridges on page 101.

●

Avoid touching the substrate while printing is in progress.

●

Trying to print jobs with a lot of ink in fast modes (commonly 6 passes or below) may result in notcompletely-dry output and/or other print-quality problems. Consider using modes with higher passes when printing with a lot of ink, or increase the curing temperature. Note that increasing the curing temperature may deform your substrate (see The substrate is deformed or wrinkled on page 67).

Improve print quality

As a first step, you may be able to improve print quality with a single command. At the front panel, press

, then Image-quality maintenance > Optimize print quality.

This performs printhead recovery, alignment, and color calibration routines, in order to optimize your print quality automatically in a single step. Allow up to 30 minutes for the printer to perform the whole process.

If you still experience print-quality problems, you can follow a more hands-on print-quality troubleshooting procedure, by printing, interpreting, and performing corrective actions.

You can print all the test plots at once for complete debugging of your print-quality problem. At the front

panel, press , then Image-quality maintenance > Print all test plots.

Alternatively, you can print the test plots individually for specific debugging of nozzle health, alignment, optimizer, or substrate-advance print-quality issues as described below.

84 Chapter 5 Troubleshoot print-quality issues ENWW

1. The printhead status plot

The printhead status plot consists of patterns that are designed to highlight printhead reliability problems. It helps to determine whether any printhead is experiencing clogging or other problems.

To print this plot, go to the front panel and press , then Image-quality maintenance > Clean

printheads > Print test plot. Vinyl, preferably gloss at least 36 inches wide, is recommended for maximum visibility. Other substrate types may not show enough detail to see the optimizer dashes clearly.

The plot consists of small dashes, one for each nozzle on each printhead.

For each individual colored pattern, make sure that most of the dashes are present.

Corrective action

1. Clean any faulty printheads. See Clean (recover) the printheads on page 105. Then reprint the

printhead status plot to see whether the problem has been solved.

2. If the problem persists, clean the printheads again, and reprint the printhead status plot to see whether

the problem has been solved.

3. If the problem continues to persist, replace any persistently faulty printheads. See Replace a printhead

on page 108.

2. The optimizer check plot

To print the optimizer check plot:

1. Use the same substrate type that you were using when you detected a problem.

2. Check that the selected substrate type is the same as the substrate type that is loaded into the printer.

Go to the front panel and press , then Image-quality maintenance > Print latex optimizer test

plot.

The latex optimizer is a transparent fluid that may not be visible on all substrates; vinyl is recommended for maximum visibility. This print consists of several area fills, text, lines and color bars. It is intended to identify print-quality problems that may be caused by optimizer nozzle defects.

ENWW Improve print quality 85

Compare the three rows.

●

The row with the symbol shows a simulated image with an above-normal amount of optimizer.

●

The row with the symbol shows a simulated image with a below-normal amount of optimizer, equivalent to more than 200 blocked nozzles.

●

The row with the rectangle around it and the symbol shows the current performance of the printer, printing 10 passes.

Look for differences in performance between the images, such as bleeding in the color bars, graininess in the area fills, blurred text, and overall print quality.

If there is little difference in quality between the rows, there are at least two possible explanations:

●

The substrate is not sensitive to the amount of optimizer. There is probably no problem with the optimizer printhead. Consider other explanations for whatever problem you have.

●

There may be a problem with the optimizer printhead if you see high levels of coalescence and bleed as in the bad examples below. In this case, try to clean the optimizer printhead; see Clean (recover) the

printheads on page 105.

NOTE: The front panel shows an advisory message if abnormal optimizer performance has been

detected.

86 Chapter 5 Troubleshoot print-quality issues ENWW

If there is a clear difference in quality between the rows, there are at least two possible explanations:

●

If the quality of the row with the symbol is higher, the substrate is very sensitive to the amount of optimizer. Go to your substrate library on the front panel or in your RIP, select your print mode, and

increase the amount of optimizer in the the advanced settings. See Add a new substrate on page 75.

●

If you see no difference in quality between the rows with the and symbols, but the row with the symbol looks worse, the substrate is sensitive to the amount of optimizer, but there seems to be no

problem with the optimizer printhead or the amount of optimizer used. Consider other explanations for whatever problem you have.

3. The printhead alignment status plot

To print the printhead alignment status plot:

ENWW Improve print quality 87

1. Use the same substrate type that you were using when you detected a problem. Or consider using vinyl

gloss substrate for better visibility of the optimizer in particular.

Go to the front panel and press , then Image-quality maintenance > Align printheads > Print test

plot.

Check the continuity of the thin diagnostic lines on the alignment status plot. In one section, colored lines are printed in line with black lines to test the alignment from one color to another. In a another section, colored lines are printed such that one half is made with a forward pass and one half is made with a reverse pass to test the alignment between the two directions. In both sets of patterns, printhead misalignment will be visible as a step in the line at its center (marked with a short black line).

Bear in mind that small misalignments may not cause any print-quality defects. The printing process is designed to hide the effects of small amounts of misalignment. The reference scale can be used to quantify the amount of misalignment; errors below 4/600 inch are unlikely to cause print-quality defects.

The optimizer fluid is transparent and cannot usually be seen directly. The fluid can be seen on some substrates (such as self-adhesive vinyl) when printed in conjunction with the colored inks. The cross pattern that is printed above the reference scale is printed in this way and can be used to evaluate the alignment of the optimizer on some substrates. In a well-aligned system, the light-colored cross at the center of the pattern will be aligned with the four black lines at the sides of the pattern. The following figure shows how this pattern will appear on the substrates on which it is visible. This sample is slightly misaligned.

88 Chapter 5 Troubleshoot print-quality issues ENWW

If the printheads are misaligned or you feel unsure about them—for example, because a substrate crash occurred—then align the printheads. See Align the printheads on page 106.

4. The substrate-advance check plot

To fine-tune the quality of your print, you may need to adjust the rate at which the substrate advances. The substrate advance determines the placement of dots on the substrate. If the substrate is not advanced correctly, light or dark bands appear in the printed image and the grain in the print may increase.

Substrate-advance adjustment is highly recommended, as the substrate advance is not automatically monitored.

You can modify the substrate advance from the RIP or front panel with the Substrate Advance parameter in the substrate preset.

To print the substrate-advance check plot:

1. Use the same substrate type that you were using when you detected a problem.

2. Check that the selected substrate type is the same as the substrate type that is loaded into the printer.

Go to the front panel and press , then Image-quality maintenance > Substrate advance calib >

Print adjustment plot.

The substrate-advance check plot consists of several columns with a number at the bottom of each one. Locate the lightest of the columns and enter its number into the Substrate Advance parameter for the current substrate preset. The value chosen in this example should be “−6”.

NOTE: Minor substrate-advance problems (±2 around the 0 value) are unlikely to result in any print-quality

problem, especially with print modes of more than 8 passes.

ENWW Improve print quality 89

Substrate advance adjustment while printing

If you are using no more than six passes, you can fine-tune the substrate advance while printing: press ,

Adjustments > Adjust substrate advance. Select a value of change from −10 mm/m to +10 mm/m (or

then mils/inch). To correct light banding, decrease the value. To correct dark banding, increase the value.

If you are using eight passes or more, a wrong advance adjustment will not produce banding but graininess, which is harder to assess visually. Therefore, in this case you are recommended to use only the adjustment plot.

When you have chosen a value and pressed OK, the rest of your job will be printed with that value, but it will be reset to zero at the end of the job. Add the value found to the Substrate Advance value in the preset to print all future jobs with the new setting.

What to do if problems persist

If you still experience print-quality problems after applying the advice in this chapter, here are some additional tips to consider:

●

Try selecting a higher print-quality option in your RIP software, by increasing the number of passes.

●

Check that your printer firmware is up to date. See Firmware update on page 129.

●

Check that you have the correct settings in your software program.

●

Call your service representative. See When you need help on page 34.

Most-common print-quality problems

Graininess

If you see this kind of problem:

●

Ensure that the vertical correction option is disabled in the RIP and in the front panel. At the front panel,

press , then Image-quality maintenance > Vertical correction (if this option is available).

●

The printheads may be misaligned. This is likely if you have not aligned the printheads for a long time, or if there has been a substrate jam. Align the printheads if necessary (see Align the printheads

on page 106). You can check whether it is necessary by using the printhead alignment status plot (see

3. The printhead alignment status plot on page 87).

●

If you are printing with eight or more passes, the substrate advance may need proper calibration. See 4.

The substrate-advance check plot on page 89.

90 Chapter 5 Troubleshoot print-quality issues ENWW

●

Use a higher number of passes: you will probably see less grain with ten or more passes.

●

If graininess is more visible in light area fills, with the appearance of coalescence graininess (see 2. The

optimizer check plot on page 85), try the following solutions:

◦

Go to your substrate library on the front panel or in your RIP. Select your print mode and increase the amount of optimizer in the the advanced settings. See Add a new substrate on page 75.

◦

Clean the optimizer printhead.

◦

Print in Economode (four colours).

NOTE: A small change in overall graininess (but not coalescence) may be perceived in some

areas because the light-colored inks, which are not used in Economode, help to provide smooth transitions.

Horizontal banding

Try the following remedies if your printed image suffers from added horizontal lines as shown (the color may vary).

●

If you are using a print mode with six or fewer passes, try increasing the number of passes. Some degree of banding can be expected with few passes.

●

If bands affect all colors across the width of the printed image, the cause is probably a substrate advance problem. Use the front panel to adjust the substrate advance on the fly (see Substrate advance

adjustment while printing on page 90). If you have dark bands, increase the substrate advance; if you

have light bands, decrease it. When you find the right adjustment, store the value in the front panel for future prints on the same substrate.

Another cause could be a fiber attached to one of the printheads. Turn off the printer, then remove the printheads one at a time and remove any fibers that you see attached to them.

●

If bands affect only some colors, the cause could be a defective printhead.

◦

Print the printhead status plot (see 1. The printhead status plot on page 85). If necessary, clean the printheads (see Clean (recover) the printheads on page 105).

◦

Sometimes a single cleaning action may not completely clean every nozzle. Print the status plot and consider cleaning again.

◦

Align the printheads (see Align the printheads on page 106). If necessary, align them manually.

◦

Print the printhead status plot again. Identify the printhead with the greatest number of blocked nozzles, and replace it.

NOTE: The optimizer printhead is unlikely to cause this kind of problem.

ENWW Most-common print-quality problems 91

●

If bands affect most of the colors, the printheads could be misaligned. This is likely if you have not aligned the printheads for a long time, or if there has been a substrate jam. Align the printheads if necessary (see Align the printheads on page 106). You can check whether it is necessary by printing the printhead alignment status plot (see 3. The printhead alignment status plot on page 87).

●

If banding occurs mostly in black areas, create a new color profile using pure black and not a mixture of other colors. See your RIP documentation.

●

Due to the printhead servicing routines while printing, some fibers or small amounts of ink may be deposited on a nozzle, causing it to fail temporarily. This is very unlikely and may just cause a couple of isolated bands. It is also very unlikely for this to be repeated within the same or subsequent print jobs. However, if you notice it, try cleaning the printheads (see

If the problem persists, call your service representative (see When you need help on page 34).

Vertical banding

Different kinds of vertical bands may appear, for different reasons.

●

Regular vertical bands matching the shape of the platen may be seen on paper-based substrates and in general on thin substrates in medium-density area fills such as grays or violets. Try the following suggestions to mitigate this problem:

◦

Align the printheads. See Align the printheads on page 106.

◦

Try the automatic correction for vertical banding. At the front panel, press , then Image-

Clean (recover) the printheads on page 105).

quality maintenance

NOTE: Remember to disable the vertical banding correction when you no longer need it, because

it may increase grain.

◦

Reduce the vacuum level in steps of 5 mmH2O when printing on vinyl. Do not exceed the lower limit of 10 mmH2O for vinyls or 25 mmH2O for papers to avoid crashes and/or smears. Consider using the substrate edge holders to avoid lateral crashes. See The edge holders on page 51.

◦

Consider using the take-up reel, for better control of the substrate.

◦

This kind of banding is less visible when the printer is stable at high temperature (after more than half an hour of continuous printing). You can help to avoid visible banding by modifying the printing queue so that vulnerable or important prints are printed later; or by pre-warming the printer by using the option available in your RIP.

●

Thin vertical dark bands, typically seen in the first 150–200 mm of the print in high-density area fills or in backlit applications

◦

Reduce the ink quantity if possible.

◦

When using backlit and synthetic substrates, decrease the vacuum level to values around 5–15, depending on the substrate thickness. More vacuum is normally applied to thick substrates and less to thin substrates.

◦

Increase the number of passes.

> Vertical correction. This option should also be available in your RIP.

◦

If applicable, use the RIP to group jobs together, so that printer temperatures remain more stable between jobs.

●

Irregular or isolated vertical bands with abnormal levels of graininess

92 Chapter 5 Troubleshoot print-quality issues ENWW

◦

Increase the vacuum level in steps of 5 mmH2O. Do not exceed the following limits: 20 mmH2O for banners, 45 mmH2O for vinyl, and 50 mmH2O for other substrate families.

◦

In backlit applications, increase the number of passes to 20, maintaining the vacuum level below 20 mmH2O.

◦

If the banding appears only at the beginning of the print, advance the substrate manually about 100–150 mm before the first print.

The print is deformed into a curved shape

This may occur as a result of substrate bow deformation. See The substrate has bow deformation

on page 68.

Misaligned colors

If the colors are misaligned in any direction, the printheads may be misaligned. This is likely if you have not aligned the printheads for a long time, or if there has been a substrate jam. Align the printheads if necessary (see Align the printheads on page 106). You can check whether it is necessary by printing the printhead alignment status plot (see 3. The printhead alignment status plot on page 87).

Color variation and text-line correction

If some printhead nozzles are in use while others in the same printhead are not, water evaporates slowly from the ink in the unused nozzles, making the color more intense. Thus, in such cases you may notice variations in color intensity in areas where the color of the image should be constant.

If you notice such a problem, there are various possible solutions.

1. If you notice the variation in intensity near one side of the print, try rotating the image by 180 degrees

before printing. This may solve the problem in some cases, as all the nozzles are refreshed whenever they enter the service station between passes.

ENWW Most-common print-quality problems 93

2. Use your RIP to add lateral color bars on the side of the plot that is close to the ink supplies. The color

bars are designed to exercise all the printhead nozzles, to prevent the problem from occurring.

NOTE: Not all RIPs provide this option.

3. Add lateral color bars to the image, manually, before printing. In this case, you can either use the

standard colors, or decide to include a particular color in which you have noticed the problem. The recommended width of each color bar is 3 mm.

At the front panel, press , then Image-quality maintenance > Color variation and text-line

correction > On.

If text, lines, or light solid areas are rough or blurred, try the following suggestions:

●

The printheads may be misaligned.This is likely if you have not aligned the printheads for a long time, or if there has been a substrate jam. Print the printhead alignment status plot (see 3. The printhead

alignment status plot on page 87), and align the printheads if necessary (see Align the printheads on page 106).

●

The optimizer printhead may have blocked nozzles. You can check this by printing the optimizer check plot (see 2. The optimizer check plot on page 85).

●

Water evaporates slowly from the ink in the unused nozzles, so the first drops of ink are ejected with lower velocity. This may happen, for example, in nozzles not used during a whole printed swath, causing the text or lines to be rough or blurred. You are recommended to go through steps 1 to 4 as described above.

●

If a light area is close to the edge while printing on a thin substrate, ensure that the substrate is loaded with the substrate edge on a rib of the platen to avoid local blurring. Alternatively, try rotating the image so that the affected area is not at the edge of the substrate.

Black areas look hazy

If black areas look hazy or not sufficiently black, try these suggestions.

●

Increase the number of passes.

●

Laminate the print.

●

Substrate presets are designed to achieve consistent and reliable print quality on a broad range of substrates. However, you may want to consider investing in the color management process, using external tools and/or experts, to get specific results. The best dark colors on gloss vinyls and other substrates are normally obtained when using as much black and as little composite as possible when creating the ICC profile.
