Substrate tips

General tips

Handle unprinted and printed substrates with care, and preferably with cotton gloves, to avoid fingerprints. For heavy rolls, use a forklift, and two people wearing security shoes.

Before loading a roll:

Check that temperature and humidity in the room are within the recommended ranges for the

●

printer. See

Check that neither the roll nor its core are bent or deformed, which may cause the substrate to jam

●

in the printer.

If the roll has been stored in a place not offering the recommended environmental conditions,

●

allow some time for it to adapt to the temperature and humidity of the printer's environment.

quality due to substrate advance errors.

You may find it easier to load a roll if you first move the carriage beam to its highest position.

●

While loading a roll, make sure the leading edge is parallel and straight across the output core, and attached evenly (start taping the substrate to the core at the center, then move towards the edges).

After you have loaded a roll:

Make sure that the edge holders are set on both sides of the roll. Do not use any other Edge

Tips for specific substrates on page 23).

Use the HP Internal Print Server to check that any required calibrations have been done: color

●

calibration, substrate-advance compensation, printhead alignment. See the Maintenance and troubleshooting guide.

For the best print quality, the substrate should stay flat and unwrinkled in the printing zone, the

●

substrate advance should be constant and the substrate should move straight.

Do not cut off pieces of substrate while the substrate is loaded into the printer. This may cause the

●

remaining substrate to jam.

After printing, try to allow 24 hours before stacking, folding or rolling printed substrates.

NOTE: Printing on porous substrates may result in visible vapor being generated from the water-

based ink.

Substrate configurations

The substrate can be loaded in a variety of different configurations to suit your different needs. Before loading, you must go to the HP Internal Print Server and select Substrate > Load/Unload, then select the configuration you intend to use.

Handle the substrate

The basic configurations are illustrated below. These configurations can be used for single-roll or dualroll printing, and for porous or non-porous substrates. Porous substrates require the use of the ink collector kit: see

The roll-to-roll configuration is suitable when you intend to print a whole roll without cutting

●

it until the input roll is empty. The substrate cannot be cut in mid-roll unless printing double-sided, and then it must be reloaded afterwards.

The roll-to-free-fall configuration (LX850 only) is suitable when you want to cut and

●

remove each print as soon as it comes out of the printer. The substrate is kept under tension between the input roll and the tension roller; but it can be cut after the tension roller because then it is no longer under tension.

The ink collector kit (LX850 only) on page 28.

24 Chapter 3 Handle the substrate ENWW

The roll-to-free-fall with collector configuration (LX850 only) is suitable when you may

●

want to cut the substrate and remove the output roll before the input roll is empty. The substrate is kept under tension between the input roll and the tension roller; but it can be cut after the tension roller because then it is no longer under tension.

Set the carriage beam position

The carriage beam position determines the vertical distance between the printheads and the platen. If it is too great, print quality will be impaired. If it is too small, there is a risk that the printheads will come into contact with the substrate, causing smears or damage.

To set the carriage beam position, go to the front panel and select the Substrate menu

Substrate management, and press OK. Select Carriage beam position. You can choose the highest position, a custom position or the normal position.

The highest position is not used for printing: it may be used for loading substrate or for

●

maintenance tasks.

A custom position is used for thick substrates, or for substrates that wrinkle slightly due to heating.

●

TIP: Try to avoid wrinkling by using substrates that do not wrinkle, or by using a slower print

mode that will allow you to lower the drying temperature.

We recommend setting the custom position to the thickness of the substrate plus two or three millimeters. The current setting is indicated in the front panel by a √ mark.

, then

Handle the substrate

ENWW

The normal position is suitable for unwrinkled substrates up to 0.7 mm (0.03 in) thick.

●

WARNING! Keep away from the printer's moving parts until the carriage beam has reached its new

position.

Set the carriage beam position

NOTE: LX850 only: If you have installed the ink collector kit, the normal position and the lowest

custom position are automatically adjusted to take account of that.

Prepare to print

The following steps that must be followed before the printer can print:

1. Ensure that the ink collector kit is installed for porous substrates, and not installed for non-porous

substrates. See

The ink collector kit (LX850 only) on page 28.

2. Start the printer. See

3. Go to the HP Internal Print Server and select Substrate > Load/Unload to open the Printer

Configuration window.

4. Select the printer configuration that you intend to use, and press Next to see the on-screen help.

Handle the substrate

Turn the printer on and off on page 12.

NOTE: The Skip Substrate load check box should be checked only if the printer has just

previously had the same configuration (i.e. the same substrate, same profile), and because of a severe system error, you had to restart the printer.

5. Load the substrate. Substrate loading instructions are displayed in the HP Internal Print Server

window. For more detailed instructions, see

roll into the printer on page 38.

6. Press the Load button in the HP Internal Print Server to start the substrate check, then enter the

substrate type in the Loaded Substrate window.

TIP: If the printer has been idle overnight with substrate loaded, and exposed to high or low

temperatures, advance the substrate 13 to 25 cm (5 to 10 in) before printing, to avoid printhead crashes or ink smears on the substrate.

The substrate edge holders

The purpose of the substrate edge holders is to prevent the substrate edges from lifting up and jamming while printing.

Standing in front of the printer, you should see the two edge holders on either side of the top surface of the substrate. Slide the edge holders to the edges of the substrate and make sure that they are properly positioned and not bent (which could cause a carriage crash).

TIP: The edge holders are easy to deploy with the carriage beam at its highest position.

The correct position is illustrated below, where (1) indicates the edge of the substrate. The substrate should be free to move, and should not touch the ends of the edge holder.

CAUTION: Wrongly positioned edge holders could severely damage the printheads and carriage.

Removal and replacement

When the printer is delivered, the edge holders are already installed on the print platen, and there is no need to remove them. When they are not being used they can be pushed to the side. However, the central edge holders used for dual-roll printing must be removed for single-roll printing and for the LX 850 when printing on textiles, as the ink collector kit must also be installed.

Handle the substrate

ENWW

To install an edge holder, stand at the front of the printer and attach the rear of the edge holder to the rear of the platen, then pull the front of the edge holder towards you and attach it to the front of the platen.

CAUTION: Do not bend the edge holder. It should remain perfectly straight, otherwise it could

damage the printheads and carriage.

In the roll-to-free-fall configuration, the output diverter is not needed.

●

In the roll-to-roll configuration, you are recommended to use both diverters, but in some cases

●

you may be able to minimize wrinkles by changing the position of a diverter or even by removing one or both of them.

13. Check that the curing plates are in the correct position for the substrate you are loading (see

curing plates on page 32).

14. Load the substrate, which should pass outside the input diverter and inside the output diverter.

15. Deploy the edge holders.

16. If you have not already done so, go to the HP Internal Print Server and select Substrate > Load/

Unload. In the load configuration, ensure that the Ink collector box is checked.

17. Lower the carriage beam to the normal position.

18. You may need to enter the left edge position and the substrate width into the HP Internal Print

Server, if the printer cannot detect them.

Uninstall the kit

The ink collector kit must be uninstalled before printing on non-porous substrates.

1. Raise the carriage beam to its highest position.

2. If any substrate is loaded, unload it. Take care that it does not touch the ink collector foams, which

may be wet with ink.

3. Remove the edge holders, and clean them if necessary.

7. Before lowering the carriage beam to the normal position, go to the HP Internal Print Server and

select Substrate > Load/Unload. In the load configuration, ensure that the Ink collector box is unchecked.

The curing plates

For efficient drying and curing, you are recommended to keep the curing plates up (horizontal) for textile and backlit substrates, and down (inclined downwards) for all other substrates.

Textile and backlit substrates

To raise a curing plate into the horizontal position, just lift it; it clicks into place.

32 Chapter 3 Handle the substrate ENWW

All other substrates

To lower a curing plate into the inclined position, you must pull the black knobs underneath the plate.

TIP: If you find that you cannot get sufficient curing for a particular substrate with the curing plates

down, you could try raising them to the horizontal position.

Load a roll onto the spindle

Single-roll printing and double-sided printing

The spindle has a pneumatic connector at one end and a gear at the other.

1. Rest the roll securely on the Spindle Supports.

2. Check that the gear is on the correct side (which depends on the intended winding direction).

3. Insert the spindle into the roll.

TIP: The spindle is quite heavy in order to ensure stiffness and so avoid skew and wrinkles, so

two people are recommended for this operation. With only one person, you are recommended to put the roll on the Spindle Supports, lift one end of the spindle and insert it into the roll, then lift the other end carefully so that the first end does not fall out, and push the spindle into the roll.

4. Connect the air gun to the pneumatic connector on the spindle, and inflate the spindle so that it

cannot move inside the roll.

ENWW

Load a roll onto the spindle

5. Note the position of the end of the roll on the scale marked at the geared end of the spindle. Its

position should be not less than 3.2 cm (1.25 in) on that scale, otherwise the substrate may go out of the print zone and start touching the printer covers. The input and output rolls should be positioned identically on their respective spindles.

TIP: When loading heavy rolls of inelastic substrates that are approximately half the spindle

length, you may find it useful to load the substrate closer to the center of the spindle, to reduce the risk of skew, wrinkles and telescoping.

Handle the substrate

TIP: If the substrate is telescoped on the input roll, there is a risk of substrate jams and damage to the

printheads. Try to straighten the edges of the substrate to minimize telescoping on the input roll before loading it into the printer.

TIP: Check that the substrate is attached to the input core.

The roll is now ready to be loaded into the printer.

TIP: If you are a regular user of different substrate types, you can change rolls more quickly if you

preload rolls of different substrate types on different spindles. Extra spindles are available for purchase,

Dual-roll printing

You can print on two rolls at the same time by using the dual-roll spindles provided with your LX850 printer or available as accessories for your LX820 printer.

The dual-roll spindle is marked to assist you in positioning the differential hub.

34 Chapter 3 Handle the substrate ENWW

Loading the dual-roll spindles

1. With the spindles inserted into the Spindles Supports, Ensure that the differential hubs on the input

and output spindles are aligned with each other.

2. When both differential hubs are correctly positioned, use an Allen key 4 to tighten the screws and

secure them in place. If a differential hub is loose, the substrate could become skewed during printing.

TIP: You should tighten the screw until the washer touches the bolt. If you can still see the yellow

spring, tighten the screw further.

TIP: It will be easier to load the roll onto the spindle if you lock the differential.

Load a roll onto the spindle

Load a roll into the printer

The objective when loading substrate is to get a uniform tension across its width and along the substrate path to minimize the risk of skew, wrinkles and telescoping. There are three configuration of loading the substrate into the printer:

Roll-to-Roll configuration

●

Dual Roll-to-Roll configuration (LX850 only, an accessory for the LX820)

●

Roll-to-Free-Fall configuration (LX850 only)

●

In each of these types of configuration there is a Substrate Loading Tool available that will help you to load the substrate quicker and easier, refer to

on page 56

Load a roll (roll-to-roll configuration)

Handle the substrate

Load a roll with the 'Substrate Loading Tool'

The substrate roll is mounted on the rear spindle and will be collected on the front spindle. The substrate goes from the rear spindle (1) over the main roller (2), over the platen (3), over the front roller (4) and then to the front spindle (5).

NOTE: The above illustration shows the substrate loaded with the printed face outwards on both input

and output rolls. You can also load substrate with the printed face inwards on either or both rolls, in which case the spindle will turn in the opposite direction. The printer asks you for the winding direction if it cannot detect it automatically.

Each of the spindles has its own motor. The motors maintain tension on the substrate. Some vacuum is applied at the level of the platen to keep the substrate flat. The substrate is moved forwards by the drive roller motor, on which there is a pinch mechanism to stop the substrate from slipping. The pinches must be up when moving the carriage beam, and down when printing or checking the substrate, otherwise a message is displayed. The accuracy of the advance is controlled by the substrate-advance sensor, or, for substrates that the sensor cannot see, by tracking the main roller movement.

Before loading a roll into the printer, you must have a roll loaded onto a spindle (the input roll) and an empty core loaded onto another spindle (the output roll). See

38 Chapter 3 Handle the substrate ENWW

Load a roll onto the spindle on page 33.

NOTE: For the output roll, use a single empty core the same length as the input core. Do not place

two or more shorter cores on the same spindle, which could cause substrate-advance problems.

TIP: The spindle by itself is quite heavy, and a roll of substrate can be much heavier. You are

recommended to use a forklift or some other equipment to move it into position; otherwise, lift one end into the printer, and then the other end.

1. Go to the HP Internal Print Server and select Substrate > Load/Unload, then select the correct

configuration.

2. Remove the substrate edge holders in the print platen, or move them aside, so that they do not get

in the way while loading the substrate.

CAUTION: Loading the substrate on top of the edge holders could severely damage the

printheads and carriage.

3. Lift the substrate pressure handles at the rear of the printer.

4. Go to the front panel and select Carriage beam position > Move to highest position.

The printer raises the carriage beam, making it easy to insert the substrate. This process takes about two minutes to complete. During this period, you can load the input and output rolls.

NOTE: While the carriage beam is rising, you can stop it by pressing the Cancel key.

TIP: If you use the Substrate loading tool, you do not need to raise the Carriage beam.

5. Bring the new roll on its spindle to the rear of the printer, with the geared end of the spindle on the

left.

6. Rest the ends of the spindle on the platforms provided at the rear of the printer; plastic pads are

provided to absorb the impacts.

9. In the same way, load the spindle with the empty core into the front of the printer. In this case, the

geared end of the spindle should be on the right.

10. Check that the printer has finished raising the carriage beam.

11. Check that the curing plates are in the correct position for the substrate you are loading (see

curing plates on page 32).

12. Pass the leading edge of the substrate through the printer to the output roll.

13. Once in front of the printer, if you find that you haven't unrolled enough substrate, select Start

main roller motion from the front panel to unroll some more. The substrate unrolls only when

you pull it.

14. If you are loading a vinyl substrate on an LX850 printer, you are recommended to use the output

diverter from the ink collector kit, to minimize wrinkles.

15. At the rear of the printer, measure the distance between the printer's left side plate and the left

edge of the substrate. This distance should be at least 145 mm (5.7 in), otherwise the edge of the substrate may go out of the print zone and start touching the printer covers.

16. At the front of the printer, the right edge of the substrate on the empty core should be at the same

distance (A) from the right side plate as the distance measured on the input side.

NOTE: When loading non-elastic substrates, a difference of 2-3 mm (0.01 in) between the

measurements from the rear side plate and front side plate may be acceptable without problems of skew or wrinkles.

Rear Front

TIP: It is important that tension is uniform across the width of the substrate. One way of

achieving this is to take the front substrate edge by its center and shake it alternately to right and left several times while at the same time pulling the substrate until it reaches the core on the output spindle.

17. When the substrate is evenly tensioned, attach it to the empty core with adhesive tape. Tape it first

in the center, and then at the left and right sides, making sure not to pull the substrate excessively or leave it wrinkled.

NOTE: The Move to printing (custom) position allows you to set the printhead-to-substrate

distance for thick substrates or substrates that may wrinkle in the print zone, to avoid ink smearing. Be aware that raising the printhead from the substrate may give poorer print quality.

WARNING! Do not insert your hands or anything else into the printer while the carriage beam

is descending.

19. Lower the substrate pressure handles at the rear of the printer. If you forget to do this, an alert will

remind you.

20. If you intend to use full bleed, do not use the substrate edge holders, but use Move to printing

(custom) to raise the carriage. Do not remove the edge holders; just move them aside at each

end of the platen.

21. If you do not intend to use full bleed, use the substrate edge holders to prevent the substrate edges

from lifting up and jamming while printing. See

22. Go to the HP Internal Print Server and press the Load button. The printer rotates both rolls to

check their diameters, and it also checks the width of the roll, the winding direction, the vacuum and the substrate advance calibration (this takes 1–2 min).

NOTE: Some substrates (such as transparent substrates) cannot be measured by the printer in

this way. In such cases, you will be asked to enter the required information manually. Use the scale on the curing module to see the value for the right-hand edge that must be entered manually in the HP Internal Print Server.

42 Chapter 3 Handle the substrate ENWW

23. In the HP Internal Print Server, choose from the list of substrate types the type that you have

loaded.

The contents of the Loaded Substrate window are determined automatically when the substrate is loaded and checked. However, if the printer is unable to detect the edges of the substrate (for instance, in the case of a transparent substrate), you will have to measure the distance of the left edge from the printer's side plate, and complete the Left Edge and Width fields yourself.

TIP: When passing the substrate's leading edge behind the tension roller, it is important to have

no excess substrate between the front roller and the tension roller, although you can leave excess substrate before the front roller at this stage. Once the leading edge has been passed behind the tension roller, you can roll a stiff substrate downwards at the front roller or pull a flexible substrate from under the tension roller through the holes provided in the substrate guide around the roller.

13. At the rear of the printer, measure the distance between the printer's left side plate and the left

edge of the substrate. This distance should be at least 145 mm (5.7 in), otherwise the edge of the substrate may go out of the print zone and start touching the printer covers.

14. At the front of the printer, the right edge of the substrate on the tension roller should be at the

same distance (A) from the right side plate as the distance measured on the input side.

NOTE: There is a square indentation in the right side plate in front of the tension roller. You

should measure the distance between the substrate edge and the inside of this indentation.

NOTE: When loading non-elastic substrates, a difference of 2-3 mm (0.01 in) between the

measurements from the rear side plate and front side plate may be acceptable without problems of skew or wrinkles.

Double-sided printing

Selecting the double-sided printing option will provide you with guidance and help specific to doublesided printing during the load process.

The roll-to-roll configuration is recommended for double-sided printing. You cannot perform doublesided printing if the dual-roll spindle or the ink collector kit is in use.

A double-sided job must be defined as a pair of images.

Side A is the first image to be printed.

●

Side B is the second image to be printed, on the reverse of Side A.

●

On Side A, after each row of images a black continuous line called a “registration line” is automatically printed: (a) and (b) below. These registration lines are used while printing Side B to minimize any registration errors in the direction of substrate movement.

When the whole of Side A has been printed, a space (c) is normally left blank for calibrations (the substrate is already warmed up), and a further space (d) is left blank so that the substrate can be loaded for printing Side B. However, these blank spaces are optional: you can turn them off.

Information about the loaded substrate is displayed at the bottom of the main screen of the HP Internal Print Server.

To see more information, select the Substrate menu and then Settings.

Substrate presets

Each supported substrate type has its own characteristics. For optimum print quality, the printer changes the way it prints on each different substrate type. For example, some may need more ink and some may require higher temperatures for drying and curing. So the printer must be given a description of the requirements of each substrate type. This description is called a substrate preset. The printer is supplied with substrate presets for some specific substrate types, and also with presets for some generic types. Each generic preset comes in three variations: with 100%, 150%, and 250% ink density.

As it is inconvenient to scroll through a list of all substrate types available, your printer contains substrate presets for only the most commonly used substrate types.

For your convenience, substrate settings from many substrate vendors have been collected at

http://www.hp.com/go/LX850/solutions/ and http:// www.hp.com/go/LX820/solutions/. You can

check substrate availability using the Media Finder application that you will find there.

Create a new substrate preset

Whenever you load a new substrate type into your printer, you must choose a substrate preset for it.

1. If possible, select a preset for the specific substrate type that you intend to load.

2. If no specific preset is available, select a generic preset that corresponds to the specific type that

you intend to load. You may be able to get better results by creating a specific preset for your substrate type.

3. If no specific nor generic preset matches your substrate, select whatever preset seems to resemble

it most closely. You will probably get better results by creating a specific preset for your substrate type.

Creating a new preset has several purposes.

quality printing to fast production output.

NOTE: You can change only the presets that you have created yourself. The presets supplied by HP

cannot be changed.

Before creating a new preset, it is useful to understand a little about how the printer works. Here are some of the available settings.

Table 3-1 Substrate preset settings

Setting If too low If too high

Number of passes

The number of passes specifies how many times the printheads will print over the same area of substrate.

Curing temperature

Curing is needed to coalesce the latex, creating a polymeric film which acts as a protective layer, while at the same time removing the remaining co-solvents from the print. Curing is vital to ensure the durability of the printed images.

Drying temperature

The heat applied in the printing zone removes water and fixes the image to the substrate.

The printer cannot deposit enough ink over a given area, so colors are muted. Because larger substrate advances are required and ink has to be placed faster on the substrate, the boundaries between passes are more visible and may be seen as horizontal lines across the image. However, printing speed is relatively high.

The print may emerge not fully dry, so that the ink smears when rubbed with a finger. The print may appear dry immediately after printing and then become wet to touch some seconds later. If the curing temperature is very low, the latex film is not created, in which durability is drastically reduced.

Print quality defects such as bleeding and coalescence may occur. Boundaries between colors are not well defined. Single-color area fills are not uniform: ink is concentrated at the edges or in clusters within the area fill.

Colors are vivid, print quality is high, and printhead health is well maintained. However, printing speed is relatively low.

The substrate may wrinkle on the platen, causing vertical banding or ink smears, with substrate jams in extreme cases. Fragile substrates may be damaged.

Thermal marks may be seen on the substrate; they may appear as vertical bands in some colors. The substrate may wrinkle on the platen, causing vertical banding or ink smears, with substrate jams in extreme cases.

64 Chapter 3 Handle the substrate ENWW

Table 3-1 Substrate preset settings (continued)

Setting If too low If too high

Substrate tension

Tension is applied at the input and the output side. It needs to be evenly distributed along the whole width of the substrate, thus substrate load is a critical operation.

TIP: Input tension should be higher

than output tension.

TIP: Output tension should be

increased whenever vacuum pressure is increased.

Airflow power

The airflow generated by the fans in the curing module is split into two air layers, one reaching the print zone and the other at the end of the curing zone. This is needed to help remove the moisture and co-solvents while the substrate is being heated by the drying and curing modules.

Vacuum pressure

The vacuum applied to the substrate in the printing zone helps to hold the substrate down on the print platen, keeping the distance to the printheads constant.

The substrate may be poorly wound onto the output roll, with sagging and skew, in which case it is likely to become increasingly wrinkled in the printing zone. Also, substrate advance could be irregular, resulting in horizontal bands.

The printer will be less able to dry the ink. In certain printing conditions (fast print modes with fewer than 5 passes and ink densities below 150%), there could be print-quality defects such as bleeding and coalescence and/or incomplete drying of the prints.

The substrate can lift up off the platen and touch the printheads. This can smear the printed image, cause a substrate jam or even damage the printheads.

The substrate may be permanently deformed or damaged.

With certain substrates and printing conditions, an excessive airflow in the print zone could cause print-quality defects such as vertical banding. Also, with some substrates, too high an airflow could prevent the printer from reaching the drying and/or curing target temperatures, causing potential system power errors.

Vertical bands can appear in some colors. Also, for sticky substrates, friction could be too high and substrate advance irregular, resulting in horizontal bands.

Ink restrictions

A way of specifying the maximum amount of each color of ink that can be laid down on the substrate.

Carriage beam position

The distance between the printing heads and the substrate is a critical determinant of print quality. It can be adjusted by modifying the height of the carriage beam above the platen.

Some colors may be too pale. The print may suffer from coalescence,

The substrate may touch the printheads. This can smear the printed image, cause a substrate jam or even damage the printheads.

Prepare the printer for a new substrate

1. Whenever possible, try to ensure that your printer is in an optimum state before you create a new

preset: run any pending maintenance task, in particular printhead checks and alignment.

2. Stop the print queue and wait for the printer to finish the current job. No jobs should be sent to the

printer until the new substrate preset is complete.

3. Load your new substrate. The process of loading a substrate into the printer has been designed to

be completely independent of the substrate type. When loading, follow the correct procedure and ensure that the roll width is specified, either automatically by the printer or by yourself. You may

NOTE: You are recommended to use the roll-to-roll configuration when creating a new preset.

4. Choose a suitable carriage beam printing position: see Set the carriage beam position

Create and name the new preset

To create a new preset, you must copy an existing preset, then rename and modify it.

1. Select Substrate > Create in the HP Internal Print Server.

2. Choose a name for your substrate.

Handle the substrate

TIP: To avoid confusing other users, it is a good idea to use the substrate's commercial name.

TIP: If you plan to use more than one ink density with this substrate, or more than one number of

print passes, include the ink density and/or number of passes in the name.

TIP: Use 100% ink density for substrates such as PVC Scrim Banner Frontlit, Green Banner,

Vinyl-Calendared, Vinyl-Cast, Blue back and Scrim banner.

TIP: Use 150 or 250% ink density for substrates such as PVC Scrim Banner Backlit, Perforated

Vinyl, Polyester Film, Polyester Fabric, Canvas Polyester and Tyvek.

4. You can now press the Create button to create a new entry in the substrates list, in the Custom

substrates category, with all its characteristics inherited from the parent substrate. Press Finish

if you do not plan to modify any substrate setting for now.

Consider how you plan to use your new substrate. If you require high-quality printing, you will need more passes; if you require fast printing, you will need fewer passes. Make a list of the print modes you are most likely to use.

Fine-tune the settings in your new preset

In the Settings pane you can modify various settings used in the printing process.

NOTE: The changes in the Settings pane apply only to the highlighted print mode, so you must

adjust each print mode independently. Any setting you have changed is indicated by an asterisk (*).

1. Select the number of print passes that you want to use. Color calibration uses six passes with

100% ink density, eight passes with 150% ink density, or fourteen passes with 250% ink density. You are recommended to create a preset suitable for color calibration; for normal printing, you may want to create other presets with different numbers of passes.

The recommended print modes for normal printing are as follows.

When you have adjusted the settings for one print mode, you can proceed to other print modes. However, it's not necessary to deal with them all at once: you can edit the substrate preset at any time by selecting Substrate > Edit in the HP Internal Print Server.

TIP: Note the settings that you used with the first print mode. You can probably use the same settings

for other modes.

There is also a possibility to change the different settings while printing (in case the substrate preset selected is a custom one). This can be done while printing, click the Print Adjustment button, and then the different settings can be fine-tuned. Note that some changes might take some time to have an impact (for example: increases or decreases in temperature).

Adjust the printing workflow for optimum color performance

1. Check your substrate's color calibration status and calibrate it if recommended, by selecting

Substrate > Color calibration in the HP Internal Print Server. See the 'Printer calibration'

chapter in the Maintenance and troubleshooting guide for more information.

2. Create ICC profiles for your substrate; see your RIP documentation for instructions. Normally, the

procedure includes setting the total ink limit as well as creating the profiles. When setting the total ink limit in the RIP, bear in mind the basic problems to be avoided: ink bleeding and coalescence, and damp prints caused by incomplete curing.

Export your new preset and profiles

Your substrate has been fully characterized from both the printer and the RIP points of view: a substrate preset is present in the printer, and one or more ICC profiles are present in the computer hosting your RIP. To export the ICC profiles, see your RIP documentation. To export your substrate preset, go to the HP Internal Print Server and follow these steps:

1. Select Substrate preset management.

2. Select the Export tab. A file with the extension oms will be saved, which can be imported by

another printer.

To import your substrate preset into another printer:

1. Select Substrate preset management.

2. Select the Import tab, then select the correct file with the extension oms.

Ink system components

Ink cartridges

Ink cartridges store the ink and are connected to the printheads, which deposit the ink on the substrate. You can purchase ink cartridges for your printer, see

How to order supplies on page 80.

Ink and printheads

CAUTION: Observe precautions when handling ink cartridges because they are ESD-sensitive

devices (see the

Each cartridge contains 3 liters of HP Latex Ink, which requires no special ventilation and creates no hazardous waste. The cartridge consists of a bag contained in a recyclable cardboard box.

Printheads

The printheads take ink from the ink cartridges and deposit it on the substrate. You can purchase printheads for your printer, see

Glossary on page 106). Avoid touching pins, leads and circuitry.

How to order supplies on page 80.

74 Chapter 4 Handle the ink system ENWW

(see the

The printer's six-color writing system uses three dual-color printheads with a total of 31,680 nozzles (5,280 per color).

Glossary on page 106). Avoid touching pins, leads and circuitry.

Printhead cleaner roll

The printhead cleaner roll is a roll of absorbent material used to clean surplus ink from the printheads after each pass over the substrate.

To change the printhead cleaner roll when necessary, see the Maintenance and troubleshooting guide. A new roll is provided in the Maintenance Kit (see

TIP: You should not touch the printhead cleaner roll except when you need to replace it. Any

interference with the roll may prevent the printer from keeping track of roll usage, in which case you may see spurious error messages, and a printing job may be cancelled unnecessarily.

Aerosol filters

The printheads produce many fine droplets of ink, most of which are placed accurately on the substrate. However, a small proportion of these droplets escape sideways; the two aerosol filters are placed on either side of the printhead carriage to intercept them.

How to order supplies on page 80).

To change the filters when necessary, see the Maintenance and troubleshooting guide. New filters are provided in the Maintenance Kit (see

How to order supplies on page 80).

Ink deposits

In order to check the status of the printhead nozzles, the printer expels a few drops of ink from each nozzle of each printhead into the ink deposits. This is done at the start of each print job, whenever a printhead is replaced, and whenever you request a printhead check from the HP Internal Print Server.

To clean the ink deposits when necessary, see the Maintenance and troubleshooting guide.

How to work with ink system components

Remove an ink cartridge

An ink cartridge should be removed and replaced when it is empty or past its expiry date. An empty cartridge is indicated in the HP Internal Print Server and by an orange blinking light beside the cartridge itself. You may also decide to remove a cartridge if it contains little ink and you want to provide for a long period of unattended printing.

The printer can continue printing without any ink cartridges for at least 20 minutes, depending on the print mode and the job being printed. Therefore, cartridges can be replaced while printing continues. A functional ink cartridge is required in order to start a new job.

A low-resolution TIFF file for use in previews

●

At least one high-resolution TIFF file containing the image to be printed

2. Select the Add New Job icon or File > Add New Job. Navigate across the network to the

folder containing the print job files, and click Open to import the job into the HP Internal Print Server.

3. The next dialog box displays information about the job.

You can change the default job name the first time you open its properties window. Once you save the job name, it cannot be changed. Use the Save As button to create a copy of an existing job with a different name.

Although you can change the substrate and print mode from this window by using the Change button, you are recommended not to do so, because it may adversely affect print quality. It is better to make such changes from the RIP.

Printing

The Job Info tab can be used to select annotations and special marks to be printed alongside the image.

The Job Notes field can be used to add some text to be printed in the bottom of each copy with the annotations, if any.

4. Click the Save button to store the job in the HP Internal Print Server for further processing.

Rotate a job

A job can be rotated by 90 degrees in either direction by using the rotation icons at the top right of the Job Properties window.

NOTE: Rotation is available only when the printer is not printing.

The effect of rotation is shown in the preview. After you press the Save or Save As button in the Job Properties window, the actual rotation of the job takes place. This could take a few minutes, depending on the image size and resolution, during which the job can be neither printed nor edited, and the job status is shown as Rotating. When it is done, the job is ready for printing.

For side A you can define the following properties:

●

Copies: One or more copies of a single job are printed on the substrate one after the

◦

other, each copy below the previous one

Repeats: The Repeats field (the number of rows of copies to be printed) is calculated

◦

automatically and cannot be altered directly.

Steps: the number of copies to print horizontally, across the width of the substrate.

◦

Step gap: the horizontal gap between copies.

◦

Repeat gap: the vertical gap between copies.

◦

Center: All layout methods give you the opportunity to define a left margin that will be

◦

left blank, or to center your jobs on the substrate so that there is an equal amount of white space on both sides.

ENWW

NOTE: To compensate for any possible registration errors that may occur, centering

the images is highly recommended.

For side B you can define the following and also review all of the above properties:

●

Rows to Register: This option enables you to choose which Image Registration Lines are

scanned by the printer, if you select 1 (the default), the printer stops printing and checks

every Image Registration Line, if you select a higher number, for example 2, the printer only scans every second Image Registration Line. This increases the speed of the job, but also slightly increases the chances of misregistration.

◦

Rotate: This option enables you to rotate the image 180

2. In the Layout tab are the following options, we recommend using these options when printing

double-sided:

Side B calibration space: When this check box is selected the printer leaves an area of

●

substrate empty after the images have been printed (the substrate is warmed-up), this is to give space to perform certain calibrations on side B that are recommended, such as the Dynamic Color Registration and the Substrate Advance Compensation. At the end of the empty space a dotted line is printed.

Side B loading space: When this check box is selected the printer will advance the

●

substrate so that there is sufficient substrate to load side B.

Preview (Image/Layout/Preview both)

There are three different previews:

1. Click the Image button and preview the selected images.

2. Click the Layout button and preview how the printer will print each side.

3. Click the Preview both button to see a simulation of how both images will print on side A and

on side B. You can use this simulation preview to check that the orientation of the images relative to each other is how you expect the finished result to be.

1. Select Side A from the drop down menu

2. Select Save or Save As.

step

At the end of each row a black registration line will be printed automatically (a). This

●

registration line will be used while printing the side B, to position the side B rows and minimize the registrations errors.

It is recommended to mark with a marker the back side of the last Image Registration Line (b)

●

to position the substrate during the side B loading process.

When the side A has been printed, after the last continuous black registration line, the printer

●

will automatically provide an area to perform the side B calibrations (c) and side B loading (d) area.

Printing

NOTE: The area dedicated to calibrations, between the continuous registration line and the

dotted line (c), must be advanced at the same speed as the printed area, and at the same temperature, to ensure an effective calibration.

4. When Side A has finished printing, unload side A, refer to Side A: Unload on page 60.

5. Check that the optical advance sensor is clean, do not hesitate to clean it, refer to the

Maintenance & Troubleshooting Guide -> Hardware Maintenance -> Clean the substrate-advance sensor.

6. Load Side B refer to

NOTE: For accurate printing we recommend that Substrate Edge Detection is selected.

7. When Side B is loaded perform the following, for more details of these procedures refer to Side B:

a. Align the dotted line with the platen

b. Perform the calibrations (advance calibrations and dynamic color registration, refer to the

Maintenance & Troubleshooting Guide).

Side B: Load and print on page 61

c. Select Side B from the drop menu.

d. Ensure that the Image Registration Line is aligned with the platen and start printing side B.

e. Configure Rows to register, refer to

f. Select save or save as.

g. Select Print Job and print the selected image.

While printing Side B the printer will automatically read each registration line and Side B will be positioned to minimize the registration errors

NOTE: To activate the side you want to print, always select it from the drop down menu first,

make any changes to the image and select save.

NOTE: If you select Print Job and the printer cannot detect the Image Registration Line, refer to

the Maintenance and Troubleshooting Guide.

Define double-sided job on page 90.

TIP: In case a particular substrate is often used for double-sided printing, to avoid having to

redo the calibration between side A and side B, a second specific substrate could be used based on the initial one. Apply the advance and dynamic color registration of the side B: select this new substrate preset each time the side B is loaded (and select the previous one each time the side A is used).

Nesting

Nesting is a layout method that allows you to choose the layout of your printed jobs on the substrate, relative to one another, instead of simply printing them one after another as usual. Jobs can be printed side by side if there is room.

TIP: Printing jobs side by side on the substrate gives you faster throughput and uses less substrate.

You can use nesting in the HP Internal Print Server, from the Choose Image File window or the Job Properties window.

The Choose Image File window

From the HP Internal Print Server's main window, click the Add New Job icon to open the Choose Image File window. You will see the Nesting check box on the bottom left of the window. If you select only one job, nesting is impossible and the box is grayed out. If you select more than one job, you can click the box to enable nesting.

NOTE: To be nested together, jobs must be of the same resolution and printed on the same substrate.

Any incompatible job is added to the queue as a separate, non-nested job, and an explanatory message is displayed.

When you press the Open button with nesting enabled, the Advanced Nesting Arrangement window opens (see

The Advanced Nesting Arrangement window on page 97).

The Job Properties window

From the HP Internal Print Server's main window, right-click the print queue to open the Job Properties window. In this window, you can click the Add New Job icon
