xi About this manual

Preface

This manual is intended for DocuColor 40 CP Color Server™ operators or administrators, or users with the necessary access privileges, who monitor and manage job ﬂow, perform color calibration, and troubleshoot problems that may arise. It describes the functions and features of DocuColor 40 CP utilities and DocuColor 40 CP WebTools for the purposes of print job management and color quality control.

About this manual

This manual is organized as follows:

• Chapter 1 describes the DocuColor 40 CP Control Panel. It explains the various messages and icons that you might see on the Control Panel and describes how to print system information pages from the Control Panel. It also explains how to properly start up and shut down the DocuColor 40 CP.

• Chapters 2 introduces DocuColor 40 CP WebTools, explains how to access them, and directs you to sources of more information (in this manual or in other manuals in the documentation set).

• Chapter 3 describes WebSpooler, which can be used to view and manage DocuColor 40 CP job activity. In addition to providing a graphic display of the job ﬂow, WebSpooler allows you to reprint or hold jobs, view and override print option settings, preview print jobs, and merge rasterized jobs.

• Chapter 4 tells you how to monitor and maintain color quality of your print output by calibrating the DocuColor 40 CP with Print Calibrator or AutoCal (with a desktop scanner).

• Chapter 5 describes advanced applications of Print Calibrator, such as creating custom calibration and simulation targets to customize the color responses of the DocuColor 40 CP.

• Appendix A lists error messages that you might see at the DocuColor 40 CP Control Panel, WebSpooler, or the DocuColor 40, and contains some troubleshooting information.

xii Preface

Terminology

Speciﬁc terms are explained as they are introduced. However, the following general terms are used throughout:

•

PostScript (PS)

DocuColor 40 CP uses this language for imaging the page and for communication with applications and with the print engine.

•

—A ﬁle consisting of PostScript commands and comments that describe the

Job

graphics, sampled images, and text that should appear on each page of a document, and the printer options that should be used in printing, such as media or color rendering style.

Spool

•

—Write to a disk. Usually used here to refer to a PostScript print job being

saved to the DocuColor 40 CP hard disk in preparation for processing and printing.

RIP

—Acronym for raster image processing, which changes text and graphics commands into descriptions of each mark on a page. In common use as a noun, a “raster image processor ” (RIP) is the computer processor that performs this function.

—The process of rendering, or imaging, a page or a job on a printer.

These concepts can explain how the DocuColor 40 CP Color Server and the DocuColor 40 work together as a powerful printing system. The D ocuColor 40 CP PostScript RIP changes text and graphics commands in PostScript into color speciﬁcations for each dot of toner deposited on a page by the DocuColor 40.

—A computer language designed as a page description language. The

DocuColor 40 CP job environments

The DocuColor 40 CP supports several levels of control of printing, job management, and setup, and offers you the ﬂexibility to choose the conﬁguration that corresponds to the requirements of your site. Your situation may correspond to one of the descriptions outlined below, or you may prefer an intermediate level of control.

At one extreme, an administrator or operator in a high-volume printing environment controls the entire job ﬂow and all printing using WebSpooler. Print jobs arriving from remote users are spooled to the server disk and stored until the operator decides it is time to print them. Additional functions (calibration, job overrides, prioritizing, font management) are reserved for the administrator or operator.

At the other extreme, anyone on the local network can control all printing and server functions; operator intervention is not necessary. Users can print from their workstations to any of the published print connections. Anyone can use WebSpooler to control any print job.

The spectrum of control that an administrator can implement is described fully in the

Conﬁguration Guide

xiv Preface

Permissions

Support for these job environments is achieved by a combination of DocuColor 40 CP Setup options. By default, anyone can access Setup (both from the Control Panel and WebSetup), but the administrator can limit access to Setup by specifying an Administrator password for the DocuColor 40 CP (see the

Also by default, anyone can log in to WebSpooler and control job ﬂow, but an administrator can restrict access to these functions by specifying an Operator password.

The three security levels from greatest to least control are:

Conﬁguration Guide

•

Administrator

—confers control of Setup and is the highest level of control. The person who has access to Setup can control the printing and job management environment by choosing which queues are enabled, and by electing to set passwords. The Administrator can also set a common web link for all users who log in to the DocuColor 40 CP using their web browser.

Operator

•

—includes control of print jobs that arrive at the server and the ability to

perform calibration.

Guest

•

—allows users to view the status of active jobs and the list of stored jobs. They cannot make changes to jobs or change their printing instructions. A password is not needed to log in as Guest and view jobs from WebSpooler.

This manual describes the features of the DocuColor 40 CP client utilities and WebTools, and all operator privileges, whether those privileges are available to everyone or are exclusive to only certain people. It also includes descriptions of administrator functions, sometimes referring you to other manuals for more information.

2. Power off the DocuColor 40 CP by moving the power switch on the back to the Off position.

OTE: After powering off the DocuColor 40 CP, make sure to also power off the

copier. Leaving the copier po w ered on while the DocuColor 40 CP is powered off can lead to excessive drain on the DocuColor 40 CP motherboard battery.

2-1 About WebTools

Chapter 2: Overview o f DocuColor 40 CP W ebTools

This chapter introduces the DocuColor 40 CP WebTools: Status, WebSpooler, WebLink, Installer, and WebSetup. It explains how to access these tools and describes their functions. For more information on WebSetup and Installer WebTools, you are referred to other manuals in the documentation set.

About WebTools

WebTools reside on the DocuColor 40 CP but can be accessed over the network from Windows 95, Windows NT 4.0, and Mac OS client computers. The DocuColor 40 CP has a home page that lets remote users view server functions and manipulate jobs. For speciﬁc information on the browsers supported with WebTools, see Getting Started.

The following DocuColor 40 CP WebTools can be accessed from the DocuColor 40 CP WebTools home page.

WebTool: Summary: For more information:

Status Shows you the jobs currently processing

and printing.

W ebSpooler Allows you to view , manipulate, reorder ,

reprint, and delete jobs currently spooling, processing, or printing on the DocuColor 40 CP. Also allows you to view, print, export, and delete the Job Log. Most of these functions require an Administrator or Operator password, if one has been set.

See page 2-4

See “WebSpooler” on page 3-1

WebLink Provides a link to another web page,

provided you have a valid Internet connection. The WebLink destination can be changed; this function requires the Administrator password, if one has been set.

See page 2-5 and the

Conﬁguration Guide

2-2 Overview of DocuColor 40 CP WebTools

WebTool: Summary: For more information:

Installer Allows you to download

DocuColor 40 CP printer ﬁle installers directly from the server.

WebSetup Allows you to modify the

DocuColor 40 CP conﬁguration (Setup) remotely . This function r equires the Administrator password, if one has been set.

Access privileges

The DocuColor 40 CP system allows the site administrator to choose and implement a level of access and control appropriate for your particular site. The levels of access allowed to remote users depend on whether the administrator has enabled use of the W ebTools, and whether a password is required to use certain features of the W ebTools.

The three possible levels of access to WebTools are Administrator, Operator, and Guest. To enable maximum password protection, Administrator and Operator passwords must be speciﬁed in Setup (see the Conﬁguration Guide).

NOTE: An Operator password can be set only by using WebSetup.

When both an Administrator password and an Operator password have been speciﬁed, the access levels are as follows:

See Getting Started

See the Conﬁguration Guide

Access level: Privileges and password requirements:

Administrator Has full access to all WebTools and DocuColor 40 CP Control

Panel functions; Administrator password required.

Operator Has access to all functions of WebTools except WebSetup and

clearing the Job Log from WebSpooler; Operator password required.

Guest Can view job status, but cannot make changes to jobs or Setup,

and cannot view the Job Log; no password required.

2-3 About WebTools

If you have been given the Operator password, you can manage job ﬂow and override print settings of your jobs with WebSpooler. If not, you can still log in as Guest and use these tools, and the Status WebTool, to track the status of your jobs. Check with your site administrator for information on your access privileges.

TO ACCESS WEBTOOLS:

1. Start up your Internet browser application.

See Getting Started for information about supported platforms and browsers.

2. Enter the IP address or the DNS name of the DocuColor 40 CP.

Check with the operator or administrator for this information.

3. If the Log In dialog box appears, select a login lev el, enter the passw or d, and click OK.

The Log In dialog box appears only if the administrator has set an Administrator or Operator password (or both).

4. When the DocuColor 40 CP WebTools home page appears, click to select one of the WebTools.

Move the cursor over the buttons to display information about the selections.

NOTE: The Conﬁgure button appears only if you logged in as Administrator. With

Administrator privileges, you can click this button and specify which of the WebTools are available to other users.

Checking DocuColor 40 CP status with the Status WebTool

You can use the Status WebTool to see what jobs are currently processing and printing. The Status WebTool does not require any special access privileges. If the administrator has enabled Web Services in Setup and has provided you with the IP address of the DocuColor 40 CP, you can use the Status W ebTool to monitor the status of print jobs as they are rasterized and printed.

To access the Status WebTool, point y our bro wser to the D ocuColor 40 CP WebTools home page and click Status. The current RIP Status and Printer Status appear in the window.

To open a new browser window for the Status display, click Float. You can then close other browser windows and leave the Status window open to continue checking the status of the DocuColor 40 CP. As long as you keep the Status window open, it is dynamically updated.

To obtain more information about the status of jobs, use WebSpooler.

2-5 About WebTools

Accessing information with the WebLink WebTool

The WebLink button on the DocuColor 40 CP WebTools home page provides a link to another web page or to multiple web pages, provided you have a valid Internet connection. The WebLink destination is initially set to www.xerox.com. The administrator at your site can set the WebLink destination. Check the WebLink sites for any information available there.

3-1 WebTools for job tracking and management

Chapter 3: Tracking and Managing Print Jobs

TO LAUNCH WEBSPOOLER:

This chapter describes the functions of the DocuColor 40 CP WebTools that let you track and manage jobs sent to the DocuColor 40 CP.

WebTools for job tracking and management

If your site administrator has enabled Web Services on the DocuColor 40 CP, you can access WebTools from Windows 95, Windows NT 4.0, and Mac OS computers with an Internet browser. The WebTools that provide job tracking capabilities are WebSpooler and the Status WebTool. WebSpooler also provides job management capabilities, provided you have the necessary access privileges (see page 2-2). For speciﬁc information on the browsers supported with WebTools, see Getting Started.

WebSpooler

WebSpooler provides a window on DocuColor 40 CP and copier functions, and an interface from which you can control those functions.

1. Launch your internet browser and enter the IP address or DNS name of the server you want to connect to.

2. If a password has been set, the Log In window appears.

To log in as Administrator, enter the Administrator password and click OK. To log in as Operator, enter the Operator password and click OK. To log in as Guest, click OK, without entering any password.

3. From the DocuColor 40 CP WebTools home page window, click WebSpooler.

For instructions on how to access the DocuColor 40 CP WebTools home page window, see page 2-3.

3-2 Tracking and Managing Print Jobs

The WebSpooler window appears in a new browser window.

Job management features

Unless passwords have been deﬁned in D ocuColor 40 CP Setup, you can log in to the WebTools home page without entering a password, and you are given full privileges to WebSpooler which include:

• A view of current printing jobs and jobs stored on the DocuColor 40 CP

• Control of printing jobs and a view of the Job Log

• Ability to clear the Job Log

3-3 Tracking and Managing Print Jobs

After the Administrator has performed Setup and speciﬁed passwords, user options depend on your login level. If you log in to the WebTools home page as Guest, you have the ﬁrst option only. If you log in as Operator, you have the ﬁrst two options. If you log in as Administrator, you have all three options. For information about Setup and specifying passwords, see the Conﬁguration Guide.

You can use WebSpooler to perform the following functions from your workstation:

• Override current job option settings

• Delete jobs

• Duplicate or rename jobs

• RIP a job and hold the raster data

• Hold jobs in the spooled area or the RIPped area

• Remove raster data from RIPped ﬁles

• Change the priority of jobs

• Edit and merge raster data jobs (DocBuilder)

• Display, print, export, or delete the Job Log

Most of these functions require Administrator or Operator privileges. However, even without a password, you can log in to the WebTools home page as Guest with viewonly privileges in WebSpooler.

Job List window

Your ﬁrst view of WebSpooler is the Job List window, which is divided into three areas by Spool, RIP, and Print status bars. The Job List window is surrounded by a frame that includes slider buttons and menus. System information indicators at the bottom of the window show the current availability of hard disk space and RAM on the currently selected DocuColor 40 CP server.

When the DocuColor 40 CP is receiving and processing print jobs, the Job List window is a dynamic display, ﬁlled with the names of jobs and their characteristics. Status bars animate in real time as new jobs are processed and printed, and jobs move to different display areas.

System information indicators

The Spool, RIP, and Print areas of the Job List window represent the stages of printing a job. Jobs come in at the top level (Spool) and drop down to the Print level, unless they are held along the way.

• Spooled jobs—Jobs listed in the area below the Spool status bar area are PostScript

ﬁles stored on the DocuColor 40 CP disk. These jobs were sent to either the Print queue (white icons) or the Hold queue (yellow icons). These PostScript ﬁles are saved on the server’s hard disk. PostScript files can come in packets from the network, or from another place on the server hard disk. Jobs are added to a queue in the order in which they arrive, and they generally move to another queue in the same order unless an operator has intervened to change the order.

• RIPped jobs—Jobs listed in the area below the RIP status bar are ready to print.

They have already been rasterized (RIPped, or processed for printing) and are waiting, in order , for access to the printer. Rasterized jobs can also be held; held jobs are shown with a yellow icon. During RIPping, PostScript commands are

3-5 Tracking and Managing Print Jobs

interpreted in the DocuColor 40 CP to allow the DocuColor 40 to print the ﬁle the way its originator intended. The result of this interpretation is a raster ﬁle associated with the original PostScript ﬁle. In this raster ﬁle (raster image), color data is associated with each dot that can be rendered by the print engine. The color data tells the print engine whether or not to apply cyan, magenta, yellow, or black toner to each position on the page.

• Printed jobs—Jobs listed in the area below the Print status bar have already been

printed. Printed jobs can be stored on the DocuColor 40 CP disk. The number of jobs that can be stored (from 1 to 99) is deﬁned in Setup. While the PostScript ﬁle is usually saved to disk, raster images are held in RAM during and after each print job. However, you can request that the DocuColor 40 CP save the raster image to disk along with the PostScript ﬁle. Saving the raster image to disk offers some advantages—raster ﬁles are already processed so they print quickly, and each part of the raster ﬁle is still identiﬁed with a page in the original document, which means that individual pages of a saved raster ﬁle can be accessed.

Errors—Jobs with an error are shown in red. To display the error, double-click the

•

job line.

If you are logged in with Administrator or Operator privileges, you can interact with a job in the window by selecting it and choosing a command from the Job menu, or by double clicking it and setting print option overrides. (However, if passwords have been set and you are logged in with Guest privileges, you can only view jobs; you cannot interact with them.)

The job icons displayed in the WebSpooler window are explained on page 3-9.

NOTE: If your job does not appear anywhere in the WebSpooler window, it may have

already been printed; if so, it will appear in the Job Log. To view the Job Log, choose Show Job Log from the Window menu. (For more information on the Job Log, see page 3-25.)

Status bars

Jobs actively involved in the three processes (spooling, rasterizing, and printing) are listed in the status bars that span the Job List window.

Status bars show the ﬁlename and user name for the active process, and an indication of its progress. Each status bar heads the list of jobs that have completed the process. Thus, beneath the Spool status bar, you see a list of spooled ﬁles; beneath the RIP status bar, you see a list of rasterized (RIPped) ﬁles. Beneath the Print status bar, you see a list of jobs that have already been printed.

NOTE: In the Spool status bar, the ﬁlename and user information always appear as

“Unknown” (as shown below). This information is not available until the job has ﬁnished spooling to the DocuColor 40 CP disk.

Active jobs and Held jobs

You can hold a job at any stage of the process we have described, as illustrated below. I n the ﬁgure, boxes indicate types of job icons you would see in the Job List window.

3-10 Tracking and Managing Print Jobs

The Spool area is both the receiving area for jobs from users on the network (Hold queue) and the waiting area for jobs that will be RIPped (jobs in the Spool queue).

Hold queue jobs When printing requires an operator (because the Print queue and

Direct connection are disabled), the operator must assign a destination to all jobs received from users on the network (icon 1 in the table above). Once assigned, jobs (icons 2, 3, and 4) move down the Spool queue for processing. All jobs printed to the Hold queue require routing by an operator.

Print queue jobs When printing does not require an operator, network jobs sent to

the Print queue appear in the Spool area where they are shown with a white printer icon (icon 2). When they reach the head of the queue, they are RIPped and printed without operator intervention.

Direct connection jobs Jobs printed to the D irect connection are not displayed in the

job lists. They are displayed brieﬂy in the status bars (where they cannot be selected) and are included in the Job Log.

RIP area

The job icons in the RIP area are described below:

RIP area icon: What it indicates: How long you see the job:

Yellow raster icon

Yellow job row

White printer icon

White job row

After a job is rasterized, it goes into the RIP area. The RIP area holds only raster data (i.e., jobs that have been rasterized). Jobs in the RIP area are either waiting for the copier to be free (Print queue jobs, icon 2 in the above table), or they are being held.

3-11 Tracking and Managing Print Jobs

Held jobs in the RIP area have already been rasterized (RIP and Hold) or they have been printed and their raster data has been routed back to the RIP area (Print and Hold), where they are shown in yellow rows (icon 1).

NOTE: Raster jobs in the RIP area that are waiting to print (icon 2 in the table above)

cannot be manipulated by job commands.

Jobs held in the RIP area remain there until the operator deletes them. Printing these jobs does not remove them from the RIP area. Instead, a copy of the job is cr eated and printed.

NOTE: For all rasterized jobs, the print option settings, in addition to the current

calibration state of the DocuColor 40 CP, remain with the saved raster data each time the job is reprinted. To print the job with new print option settings and with new calibration data, you must remove the raster data and reRIP the job.

Print area

The job icons in the Print area are described below:

Print area icon: What it indicates: How long you see the job:

White printer icon

White job row

White raster icon

White job row

The Print area, also referred to as the Printed queue, contains jobs that have already been printed. These jobs were assigned the Print destination (white printer icon in the Spool or RIP areas) without any Hold instructions; therefore, they all hav e white icons and rows.

NOTE: A job row that appears in light red indicates that a PostScript error occurred

while printing the job. To see the error, double-click anywhere in the row.

PostScript data only—raster data has been deleted

active job, the raster data is deleted and the job gets the PS icon (icon 1, above)

Until the job limit is reached

Until the job is reprinted or the job limit is reached

3-12 Tracking and Managing Print Jobs

Newly printed jobs are added to the Printed queue, and ar e shown at the top of the list. Jobs are saved in the Printed queue until the job limit is reached. When the ﬁrst job over the limit is printed, the oldest job is deleted from the disk. The default job limit is 10 jobs. The value for Jobs Saved in Printed Queue can be changed in Setup by the administrator.

NOTE: If you reprint a job in the Printed queue, the job returns to its original position

in the Printed queue after it is printed.

While it is printing, a job consists of PostScript and raster data. The raster data in RAM is not cleared until memory is needed to rasterize the next job. As long as the raster data is intact, the job can be reprinted from the Printed queue. Printed jobs that still have their raster data are represented by a white raster icon in the Printed queue (icon 2 in the previous table); jobs with only PostScript data r emaining are r epresented by a white PS icon (icon 1). If the job was printed from a held raster job (in the RIP area), the raster data in the RIP area remains and can be used to reprint the job after the raster data has been cleared from the Printed queue.

Job commands

Using the commands in the Job menu, you can alter the destinations, priorities and other characteristics of jobs that appear in the WebSpooler window.

Job commands are used to assign a selected job to a new destination or process. These commands are available from the Job menu (see page 3-5). The job commands available at a given time depend on the context; unavailable commands are dimmed.

3-13 Tracking and Managing Print Jobs

The job commands available for selected jobs in the Job List window are listed in the following table. The table also describes the effect of each command on raster data associated with the affected job(s).

The options you set here are the same ones you set from the P rint dialog box when you print from an application. For information about print options, see the P rinting G uide.

For some options, changing the setting requires that the job be reRIPped; these options show an icon to the left of the option name.

For PDF ﬁles, you can override only the number of copies and page range from the Properties dialog box.

If you want to retain a copy of the job with its original settings, duplicate the job and rename the duplicate before you change any settings (see “Job commands” on page 3-12).

The Override Print Settings dialog box displays all the job settings encoded by the PostScript printer driver that can be decoded by the DocuColor 40 CP. If you (as operator) have not changed anything, these are the settings a user entered before sending the job.

The WebSpooler includes a powerful DocBuilder tool that allows you to preview and edit raster data. (For information on how to identify a raster data job, see page 3-9.) DocBuilder consists of two thumbnail windows and several page-manipulation commands (listed in the Page menu).

The DocBuilder tool can be used in the following ways:

• In the Thumbnail A window, you can see thumbnails of the currently RIPping job, as it is processed, or of any raster data job.

• From the Thumbnail A window you can open a full-screen preview of a raster ﬁle.

• Using the Thumbnail A and Thumbnail B windows together, you can merge raster data from more than one ﬁle, even if the ﬁles were printed from different applications on different computer platforms.

DocBuilder’s merge features eliminate the limitations of particular software applications. You can merge raster pages of documents of different types, and even different computer operating systems. You can merge color pages from graphics programs with text pages from a word processor.

Previewing print jobs

You can use the Thumbnail A window to preview pages of the currently RIPping job. You can also use Thumbnail A, as well as Thumbnail B, to preview any raster data job in the RIP or Print areas.

The thumbnail windows also allow you to open an editable thumbnail view of a held raster job in the RIP area and perform electronic collation or document merging. This feature, called DocBuilder, is described on page 3-18.

To see the progress of jobs as they are RIPped, you can leave the Thumbnail A window open in RIP preview mode.

Editing and merging ﬁles with DocBuilder

When you select a raster data job and choose the Thumbnail A or Thumbnail B command from the Job menu, the corresponding Thumbnail slider opens automatically , displaying thumbnails of the editable ﬁle. To close the Thumbnail slider, click anywhere in the tab along the right edge of the Thumbnail window. When the Thumbnail window is open, the arrows in the tab point to the right, indicating that clicking the tab retracts the slider.

With the Thumbnail A window you can see thumbnail views of any raster data job— that is, any ﬁle that is currently RIPping, or any ﬁle that has been RIPped and held to disk. You can also use the Thumbnail A window to edit a raster ﬁle—you can change the sequence of pages, delete pages, duplicate pages, and copy pages from other raster ﬁles into the Thumbnail A window. You can save the edited raster ﬁle as a new printable document.

The Thumbnail B window can also display thumbnails of a raster job, and the document displayed in Thumbnail B can be used as a source for editing the document shown in Thumbnail A.

NOTE: Be careful not to delete a Thumbnail job entirely without ﬁrst saving a copy.

You can merge documents by dragging (copying) one or more entire pages from Thumbnail B to Thumbnail A. This creates a new document in the Thumbnail A window. If you select one or more pages in the Thumbnail A window, the commands in the Page menu give you additional editing possibilities. Multiple undos of Page menu commands are possible.

You can merge pages from multiple documents into the Thumbnail A document by opening documents one after another in the Thumbnail B window. Documents in the Thumbnail B window are view-only, and while you can copy pages from Thumbnail B to Thumbnail A, you cannot edit the Thumbnail B document. A merged document that you create in Thumbnail A can be saved (with a different name) as a new raster data ﬁle.

The ability to work with raster ﬁles gives you new opportunities to combine documents from different sources into a single printer ﬁle. For example, you can combine full color covers and chapter head pages created in a page layout application with two-color text pages created in a document processing application. Or, you can customize a slide presentation by inserting slides from a different presentation.

3-20 Tracking and Managing Print Jobs

You can display two raster ﬁles at once: a source ﬁle and a target ﬁle. The target ﬁle is displayed in the Thumbnail A window, the source in Thumbnail B. Both ﬁles must be held raster jobs in the RIP area.

NOTE: You cannot create a new PostScript ﬁle in this process; you must print the

merged raster ﬁle, which has references to the original P ostScript ﬁles. Before editing or merging ﬁles with DocBuilder, make sure the source ﬁles were RIPped using the print option settings and the resident calibration you want for the ﬁnal output. Raster ﬁles edited with DocBuilder cannot be reRIPped.

TO VIEW AND EDIT RASTER DATA JOBS:

1. Select a raster data job and choose Thumbnail A from the Job menu.

The ﬁle must be a held raster job in the RIP area.

Multiple undos are available; use the Undo command (from the Page menu) to undo all the way back to your ﬁrst edit. There is no Redo function.

NOTE: Make sure to save the merged job before deleting any of the source jobs you used

to create the merged job. Thumbnail B pages moved into Thumbnail A adopt some speciﬁc attributes of the

Thumbnail A job, such as the document and user name. However, many color-related print options that are set in the Thumbnail B page, such as CMYK Simulation and Rendering Style, remain with the speciﬁc page. This could r esult in a merged job being made up of pages with different attributes.

Generally, the print option settings speciﬁed for the Thumbnail A job that are adopted by the pages copied from Thumbnail B do not require reRIPping to take effect. The one exception is the setting speciﬁed for the Save Fast Reprint option, which requires reRIPping if you want to change it.

4-1 Introduction to color calibration

Chapter 4: Color Calibration

Calibrating the DocuColor 40 CP ensures consistent, reliable color output. You can calibrate the DocuColor 40 CP in the following ways:

• Using AutoCal from the DocuColor 40 CP Control Panel—AutoCal allows you to

obtain measurements from the DocuColor 40 and apply a calibration using a desktop scanner.

• Using Print Calibrator and a scanner or densitometer from a remote computer—By

connecting an X-Rite DTP32 automatic scanning densitometer to the serial port on your computer, y ou can quickly measure color patches and do wnload measurements to the DocuColor 40 CP using Print Calibrator.

This chapter describes the purpose of calibration and provides instructions for all calibration procedures. Calibrating with AutoCal from the DocuColor 40 CP Control Panel is described ﬁrst; calibrating with Print Calibrator is described on page 4-6.

For information on advanced calibration and simulation features available with DocuColor Print Calibrator, such as editing targets and creating custom targets, see Chapter 5.

Print Calibrator procedures described in these chapters are fundamentally the same for Windows and Mac OS computers. The main differences are the interface cable and the port used to connect to the densitometer. The term “computer” is used to refer to any computer running Print Calibrator.

Introduction to color calibration

A calibration is generated from two components that originate separately: measurements and a target.

• Measurements represent the actual color behavior of the DocuColor 40; they are

computed from readings taken by a scanner or a densitometer.

• Targets represent the goal of printing, such as obtaining pleasing color from the

DocuColor 40 or simulating another print device. A DocuColor 40-speciﬁc target is provided with the DocuColor 40 CP.

4-2 Color Calibration

Calibration generates curves describing various color densities based on a speciﬁed target and a set of measurements that you provide.

Once you have calibrated the DocuColor 40 CP with AutoCal or Print Calibrator, a calibration is stored on the DocuColor 40 CP; this calibration is referred to as the “resident calibration.” The resident calibration is applied to all print jobs unless bypassing of calibration is speciﬁed by setting the CMYK Simulation print option to Match Copy (see the Printing Guide).

NOTE: Changing the resident calibration has the potential to affect all jobs for all users,

so you may want to limit the number of people authorized to perform calibration. An Administrator password can be set to control access to calibration from the DocuColor 40 CP Control Panel. Administrator and Operator passwords can be set from WebSetup to control access to calibration with Print Calibrator.

Understanding calibration

The DocuColor 40 CP allows you the ﬂexibility to choose a standard calibration or a custom calibration. A standard calibration uses the target provided with the DocuColor 40 CP with a new set of measurements.

Calibration allows you to:

• Maximize the color reproduction capabilities of the DocuColor 40 CP

• Ensure consistent color quality across time

• Produce consistent output across DocuColor 40 CP servers of the same engine

• Achieve better color matches when reproducing spot colors, such as PANTONE

colors or other named color systems

• Optimize the DocuColor 40 CP for using ColorWise Color Rendering Dictionaries

(CRDs) and CMYK simulations, and for using ICC-compatible proﬁles when printing RGB color data

Chapter 5 discusses advanced calibration techniques, including how to:

• Use the DocuColor 40 CP as a prooﬁng system by printing press simulations

• Create custom calibration and simulation targets

4-3 Understanding calibration

How calibration works

Success in obtaining satisfactory print quality from a digital color printer depends on many factors. Among the most important are establishing and maintaining optimal toner densities. Density is a measure of the light absorbed by a surface. By carefully regulating toner densities, you can obtain consistent printed color.

Even with a calibrated system, toner density is affected by such variables as room humidity and service settings; it also tends to drift over time. Regular measurement detects day-to-day variations in densities, and calibration corrects for them.

Calibration works by creating calibration curves on the DocuColor 40 CP that compensate for the difference between actual and desired density values.

Calibration curves and target curves are the graphic equivalent of transfer functions, which are mathematical descriptions of changes that will be made to the data you start with. Transfer functions are often graphed as Input/Output curves.

Target curves (targets, for short) result from applying one or more transfer functions in sequence. The server generates calibration curves after comparing measured values to the ﬁnal target values for each of the four toner colors.

Measurements

Measurements ﬁles contain numerical values that correspond to the toner density produced by the DocuColor 40 when it prints solid cyan, magenta, yellow, and black, and graduated tints of those colors.

To create a measurements ﬁle, you ﬁrst print a page of color patches from the Control Panel or from Print Calibrator to the DocuColor 40. Then you measure the patches, using either a desktop scanner or an X-Rite DTP32 densitometer. The new measurements are automatically downloaded to the DocuColor 40 CP.

You can print a calibration Comparison Page showing the result of using the new measurements with any of the current targets. When you are satisﬁed with a particular combination of measurements and target, you apply the calibration to the DocuColor 40 CP; this becomes the new resident calibration.

4-4 Color Calibration

NOTE: You might also be able to create measurements with a different brand Status T

densitometer if the densitometer manufacturer provides utility software to create a measurements ﬁle.

Targets

Target ﬁles deﬁne desired calibration results. A copier-speciﬁc target ﬁle is provided with the DocuColor 40 CP. You can create additional custom targets by modifying an existing target with Print Calibrator. When you calibrate the DocuColor 40 CP, you can select the target ﬁle that corresponds to the typical printing goals at your site. This becomes the resident calibration target that is used by default.

You can store targets on the computer where you use Print Calibrator, on another connected disk, or on the DocuColor 40 CP disk (or all three).

Scheduling calibration

In general, you should calibrate the DocuColor 40 CP at least once a day, depending on the volume of print jobs. If it is very important to maintain consistent colors, or if the DocuColor 40 is subject to wide ﬂuctuations in temperature or humidity , calibrate every few hours. Calibrate when you change paper stock. In general, to get the best performance from the DocuColor 40, calibrate whenever there is a noticeable change in print quality.

If you need to split a print job into two or more batches, it is especially important to calibrate before printing each batch.

You should also calibrate the DocuColor 40 CP system after DocuColor 40 maintenance. However, because the DocuColor 40 may be less stable immediately after maintenance, wait until you have printed approximately 50 pages before you calibrate.

NOTE: Output from the DocuColor 40 is very sensitive to changes in temperature and

humidity. To minimize these effects, the DocuColor 40 should not be installed near a window or in direct sunlight, or near a heater or air conditioner. Paper is sensitive to climate changes as well, and should be stored in a cool, stable environment.

4-5 Understanding calibration

The DocuColor 40 has a self-calibration feature (Automatic Gradation Adjustment, or AGA) that optimizes toner densities after scanning two test prints on the DocuColor 40 glass. The DocuColor 40 has a self-calibration feature that optimizes toner densities. If you never calibrate the DocuColor 40 CP from Print Calibrator or from the Control Panel, the self-calibration feature can improve the color output of print jobs. Using the DocuColor 40’s self-calibration feature alone will not necessarily bring output densities from the DocuColor 40 to the optimal values for DocuColor 40 CP printing. However , if y ou regularly calibrate the DocuColor 40 CP, your print jobs can sometimes be improved by asking a service technician to disable the DocuColor 40’s self-calibration feature.

The DocuColor 40 allows you to adjust printed color from its touch panel display . You can typically increase or decrease toner density for one or all toner colors. These control panel settings affect copies made from the DocuColor 40 glass, and may affect DocuColor 40 CP output as well. If they do, make sure these settings remain the same (preferably at a neutral position) prior to calibration, and from one print job to the next. If you change these settings, calibrate the DocuColor 40 CP when you have ﬁnished changing settings.

Print some standard color pages such as the Color Charts from the Control Panel and the Color Reference pages included with the user software (see Getting Started). All of these pages include fully saturated color patches and pale tints of cyan, magenta, yellow, and black. Images with skin tones offer a very good basis for comparison. You can save and compare pages you printed at different times. If there is a noticeable change in appearance, you should calibrate the DocuColor 40 CP system.

If the solid density patches (100% cyan, magenta, yellow or black) look less saturated with time, show the pages to the DocuColor 40 technician to ﬁnd out whether adjusting the DocuColor 40 can improve the output.

Checking calibration status

You can check whether the DocuColor 40 CP is calibrated, what target was used, and when the printer was last calibrated. You can view information about the last calibration:

• By printing a Conﬁguration page or Test Page from the Control Panel.

4-6 Color Calibration

• With Print Calibrator, by choosing Server Status from the Server menu (see

page 4-15).

Calibrating with AutoCal from the Control Panel

You can calibrate the DocuColor 40 CP from the Control Panel using AutoCal, which calibrates the DocuColor 40 CP using a desktop scanner as a densitometer. If an Administrator password has been set, you will need it for calibration.

For instructions on using the DocuColor 40 CP Control Panel, and for more details on the AutoCal options, see the Conﬁguration Guide.

Connecting the scanner to the DocuColor 40 CP

Print Calibrator is designed to work with a desktop scanner. Before you calibrate the DocuColor 40 CP, you need to connect the scanner to prepare for measuring the printed patches. For additional information on setting up and using the scanner, see the documentation included with it.

TO CONNECT THE SCANNER TO THE DOCUCOLOR 40 CP:

Calibrating with Print Calibrator

Print Calibrator allows you to calibrate from a computer networked to the DocuColor 40 CP. You can calibrate to the target provided with the DocuColor 40 CP as described in this chapter, or you can customize targets and calibration curves to suit the speciﬁc needs of your printing environment as described in Chapter 5. Print Calibrator is designed to work with the X-Rite DTP32 reﬂection densitometer so that color measurements are entered automatically. You can also use color measurements from a desktop scanner.

4-10 Color Calibration

Using a scanner

If you are using the scanner, you must perform calibration from the Control Panel before using Print Calibrator. Because the scanner is connected to the DocuColor 40 CP instead of your computer, the color measurements ﬁle from the scanner must be stored on the server before you can use Print Calibrator.

Using a densitometer

Before you calibrate the DocuColor 40 CP, you need to connect, conﬁgure, and calibrate the densitometer to prepare for measuring the printed patches (see “Calibrating the densitometer” on page 4-23). For additional information about setting up and using the densitometer, see the documentation included with it.

TO CONNECT THE X-RITE DTP32 TO THE COMPUTER:

To view current calibration information, choose Server Status from the Server menu.

If the DocuColor 40 CP is calibrated, the Server Status dialog displays the user name or login name of the person who last calibrated the DocuColor 40 CP, the name of the current DocuColor 40 CP, the date and time of the current measurement ﬁle, the name of the resident calibration target, and the date and time of the most recent calibration.

Measurements

Measurements ﬁles provide toner values that correspond to standard color patches. Typically, you measure a page of patches with a densitometer and the measurements are loaded on the DocuColor 40 CP.

The creation date and time of the current measurements ﬁle appears below the Measurements button in the Calibration Mode window.

NOTE: For demonstration purposes only, if you do not have a measurements ﬁle,

you can use the to calibrate the DocuColor 40 CP.

Measuring values with a DTP32 densitometer

To create a measurements ﬁle you print a patch page and feed it into the densitometer. The densitometer scans the density of the patches on the page and automatically transmits the measured values to DocuColor Print Calibrator.

After each column of patches is scanned, you move the page to scan another column. The DTP32 densitometer has an adjustable strip guide to the right of the strip entrance. The density measurements are used to cr eate a M easurements ﬁle. In general, valid measurements for all patches fall within the range of 0 to 3.05. Values between

-0.01 and +0.005 are shown in DocuColor Print Calibrator as 0. Values that appear in the Measurements window as negative numbers might indicate a problem with the densitometer.

TO PRINT PATCHES FOR MEASUREMENT:

1. From the Calibration Mode window, choose Print Patch Page from the Measurements menu.

2. Select a page size and paper tray.

Letter/A4 prints 21 patches per color; 11x17/A3 prints 34 patches per color. The DocuColor 40 CP downloads the patch page to the DocuColor 40. The patch

page has four columns of progressively less saturated tints of each process color.

TO PRINT SPECIAL PATCHES FOR CALIBRATING:

• With Downloader for Windows, download one of the following from the Clrﬁles\Calibrat folder on the User Software CD: Custom21.ps or Standard21.ps (21 patches) Custom34.ps or Standard34.ps (34 patches)

TO VIEW STORED MEASUREMENT VALUES:

• Click the View Measurements button to view values in the current measurements ﬁle.

Print Calibrator displays the current measurements on the DocuColor 40 CP. They are the measurements that were stored on the DocuColor 40 CP when you last clicked Accept.

Testing and applying calibration

You can view a sample calibration before applying it to the DocuColor 40 CP as the resident calibration. Since the measurements have already been updated, you are actually checking the combination of your measurements with one or more targets.

You can use the Comparison Page provided with the DocuColor 40 CP to test a calibration before applying it. This page shows a comparison of uncalibrated and calibrated data.

The Comparison Page provides the following calibration information:

Calibration checklist

Once you have calibrated the DocuColor 40 CP and, if necessary, adjusted your target to get satisfactory output, calibrating again is just a matter of taking new color measurements and applying them to the current target. A summary of the steps follows.

Prepare the densitometer

Connect and conﬁgure the densitometer. If color is critical, calibrate the densitometer. Otherwise, wait until you are prompted

to do so.

Use Print Calibrator

Start Print Calibrator. Check the target indicated in the main window. This is your current target. Choose Print Patch Page from the Measurements menu. Choose Densitometer from the Measurements menu. Choose the densitometer port and click Start. Pick up the patch page from the DocuColor 40 and feed it into the densitometer,

following the prompts in the Densitometer dialog box on the Print Calibrator screen. When you have measured all four colors, click Accept in the Densitometer dialog box.

4-23 Calibrating with Print Calibrator

Check the results

Click Test in the main window to print a calibration Test Page. Compare the calibrated and uncalibrated color. If the result of using the new

measurements is satisfactory, click Apply Calibration. If not, either measure again or edit the target, and test once more before clicking Apply Calibration.

Click OK in the conﬁrmation dialog boxes and close Print Calibrator.

Calibrating the densitometer

You will need the black-and-white Auto-Cal strip included with the densitometer. Calibrating the densitometer does not require DocuColor Print Calibrator.

5-1 Using advanced calibration features

Chapter 5: Advanced Print Calibrator Topics

This chapter describes advanced features of Print Calibrator, including customizing calibration and simulation targets. For introductory information about Print Calibrator and for instructions on performing calibration, see Chapter 4. For information on the simulation capabilities of the DocuColor 40 CP, see the Printing Guide.

The Print Calibrator procedures described in these chapters are fundamentally the same for Mac OS and Windows computers. The main differences are the interface cable and the port used to connect to the densitometer. The term computer is used to refer to any computer running Print Calibrator.

The following section describes the advanced calibration features of Print Calibrator. For information on working with simulations, see “Using advanced simulation features” on page 5-11.

Using advanced calibration features

Print Calibrator offers additional ﬂexibility for advanced users. You can:

• Use a different measurements ﬁle stored on your computer

• Select a different target when your printing goals change

• Edit an existing target to suit your needs, test it, save it as a custom target, and save it

on the DocuColor 40 CP

• Save measurements as a target

• Back up the targets that are stored on the server

• Remove targets from the server

Choosing a measurements ﬁle

Although you can import a saved measurements ﬁle, the measurement ﬁle you use should reﬂect the current color behavior of the copier. Therefore, import saved measurements only if you have reason to doubt your current measurements, or if you don’t have access to a scanner or densitometer. You cannot edit measurement values with Print Calibrator.

5-2 Advanced Print Calibrator Topics

NOTE: The measurements ﬁle is copied to the server as soon as you load a new one. It is

also copied as soon as you accept new measurements in the Densitometer dialog box (see Chapter 4).

Any measurement accepted or imported into DocuColor Print Calibrator automatically becomes the measurements ﬁle for the connected DocuColor 40 CP. This measurements ﬁle is used to create the resident calibration as well as all the other calibrations stored on the DocuColor 40 CP.

NOTE: You should view or back up the current measurements before changing them.

TO USE A MEASUREMENTS FILE:

1. To view the density values in the current measurements ﬁle, click the Measurements button.

2. To back up the measurements, choose Export from the Measurements menu and enter a descriptive name.

3. To use a different stored measurements ﬁle, choose Import from the Measurements menu and select a saved measurements ﬁle from your computer.

Working with targets

The target ﬁle provided with the DocuColor 40 CP contains desired calibration goals. You can view your current measurements and compare them with the current target. You can also edit the target ﬁle and save the changes as a new target ﬁle. This allows you to ﬁne-tune the calibration on the DocuColor 40 CP to meet your exact speciﬁcations.

Custom targets are always based on an existing target. Select the target to use as a base for the custom target on a target. In most cases, you’ll use the copier target.

The target for the resident calibration can be the provided target, or a custom target with any name. (Instructions for creating custom targets are provided later in this chapter.) S elect a target to use for the resident calibration, and click A pply Calibration.

5-3 Using advanced calibration features

You can test calibrations by comparing calibrated and uncalibrated image data on the Comparison Page, which uses both CMYK and RGB images. You can also create a custom comparison page as described on page 4-21.

Comparing the measured and target curves

Before editing a target curve, compare it to the current measured curve. By doing so, you can determine how close the measured color densities are to the target densities. The closer the measured densities are to the target densities, the better the results you get from calibration.

NOTE: Large differences between the standard copier target and measured curves may

mean that the copier needs servicing.

TO COMPARE THE MEASURED CURVE AND THE CURRENT TARGET CURVE:

1. Start Print Calibrator and select a target from the list of available target ﬁles.

The targets in this list are stored on the DocuColor 40 CP. Alternatively, click Local to use a target stored on your computer.

2. Click OK.

3. Click the Edit Calibration button in the Calibration Mode window.

4. Select Target/Measured and turn on the Measured option in the View Curves region.

These curves represent the values in the measurements ﬁle and cannot be changed.

5-5 Using advanced calibration features

Customizing calibration targets

The copier’s calibration target provided with the DocuColor 40 CP should be used for general printing purposes. You may, howev er, have special printing needs that require a custom calibration. In this case, you can use Print Calibrator to edit an existing calibration target and save it as a custom target.

The Edit Calibration window provides information about your current target and measurements in graphic form and lets you edit curves and values to create a new target.

NOTE: All changes are stored as you make them. To discard changes, reload the target

from the server or your computer.

The graph on the left side of the window allows you to view and manipulate color output values. The View Channels check boxes (beneath the graph) and the View Curves areas (to the right of the graph) specify the curves displayed on the graph.

You can change several components of a target. The changes are accumulated in the custom target that you eventually save. You can:

• Change the maximum density (Dmax).

An adjusted target is created with the new maximum density.

5-6 Advanced Print Calibrator Topics

Independently, you can:

• Adjust brightness

• Adjust dot gain for more saturated output without affecting the overall color balance

• Load a custom curve and edit points in the curve

The current custom curve is applied to the original target curve or, if you adjusted the Dmax, it is applied to the target with the new maximum density.

• By clicking Save, save a copy of the edited target to your computer

• Choose Apply Calibration when you are ready to update the resident calibration on

the DocuColor 40 CP

NOTE: The values in the following illustrations do not represent standard values. They

are intentionally exaggerated for example purposes.

TO ADJUST MAXIMUM DENSITY (DMAX):

1. Select the target to edit (see page 4-13).

2. Click the Edit Calibration button.

3. In the View Curves area, click Target/Measured and Target.

4. For each color, enter a value in the Maximum Density areas, and press Tab or Enter to adjust the endpoint of the target curve as needed.

You can enter a value from 0.1 to 3.0. The rest of the curve adjusts to make a smooth transition to the new endpoint. The

adjusted target is stored. To discard changes, reload the target from the server or from the local disk.

TO CUSTOMIZE A TARGET:

1. Select the target to edit (see page 4-13).

2. Click the Edit Calibration button.

5-7 Using advanced calibration features

3. In the View Curves area, click Custom to edit the input/output curve.

The graph maps input ink percentage to output ink percentage by analogy to ink on a press. Initially, the graph is a 45° straight line; that is, input values equal output values. This is the starting place for your editing.

As you make changes, you either increase or decrease the amount of toner that will be used to render a certain percentage tone. An ink density of 100% is a fully saturated color; 0 to 5% is a highlight color.

4. In the View Channels area, select the channels to edit.

You can view information for all four colors at the same time (cyan, magenta, yellow, and black), or any combination of these. Working with only one or two colors at a time helps you to distinguish the curves and to ﬁne-tune your adjustments, especially when using a monochrome monitor.

5. In the “Apply setting to” menu, choose the channel to adjust in the Lightness/ Darkness area of the window.

6. Use the Brightness menu to adjust brightness as needed.

5-8 Advanced Print Calibrator Topics

7. Adjust the dot gain as needed.

8. In the graph, drag points to adjust the curve as needed.

These values are used independently of the Brightness curve. Changing the values for dot gain can give more saturated color output without affecting the overall color balance. The dot gain values simulate dot gain, not compensate for dot gain.

You can choose either the North American or European standard and then enter the desired Dot Gain. The valid values for North American gain at 50% input are 0% to 50% output. The valid values for European gain at 40% input must be less than the 80% input setting plus 40%; the valid values for European at 80% input are 0% to 20% gain on output.

If you use Dot Gain values, the curve will be smoothed so that there are no spikes or jumps in output value.

NOTE: You should measure this value from actual press output, using a densitometer.

The graph maps input percentage to output percentage in 10% increments. Points along the curve are marked so that you can adjust them.

NOTE: You should adjust points in this way after you have applied a brightness or dot

gain curve. If you attempt to change a brightness or dot gain setting after you have adjusted the points on the graph, your earlier changes are not registered.

Mode window, or customize the target further.

If you edit a local target ﬁle, you are prompted to save it on the DocuColor 40 CP before calibration can be changed.

NOTE: You cannot use the name of an existing target.

11. To save the target on your computer, click Save (in the Edit Calibration window) and enter a name for the new target.

You can use a saved target again or continue editing it later.

Backing up DocuColor 40 CP targets

If you think you may need a target later, you can back up the target to your computer before you delete it from the DocuColor 40 CP. You should always back up targets before updating DocuColor 40 CP system software to ensure that no custom targets are lost.

TO BACK UP TARGETS:

• Choose Back Up Targets from the Server menu.

This copies the target ﬁles from the DocuColor 40 CP to your computer.

5-10 Advanced Print Calibrator Topics

Deleting custom targets

If desired, you can delete custom targets permanently from the DocuColor 40 CP. Y ou may want to do this to make sure no one applies a calibration using the wrong target ﬁle. You cannot delete the original target.

TO DELETE CUSTOM TARGETS FROM THE DOCUCOLOR 40 CP HARD DISK:

1. Start Print Calibrator.

2. Choose Delete Target from the Server menu.

3. Select the target and click OK. N

OTE: Deleting the target used for the resident calibration does not affect the resident

calibration. To delete a calibration based on a deleted target, you must apply another calibration that uses a different target, or remove calibration as described in the next section.

Removing calibration

If desired, you can remove calibration from the D ocuColor 40 CP. When y ou remove calibration, the resident calibration curves are removed, and a default calibration is restored. This default calibration is not optimized for the copier and is not recommended for general use.

TO REMOVE CALIBRATION:

1. Choose Remove Calibration from the Server menu.

2. When prompted, conﬁrm that you want to remove calibration.

5-11 Using advanced simulation features

Using advanced simulation features

Print Calibrator offers simulation features for advanced users. You can:

• Change the default simulation on the DocuColor 40 CP

• Edit an existing simulation to suit your needs, test it, save it as a custom simulation,

and save it on the DocuColor 40 CP

• Back up the simulations that are stored on the server

• Remove simulations from the server

Working with simulations

Simulations, or press simulations, allow you to use the DocuColor 40 as a prooﬁng device for jobs that will print on an offset press. Because the range of colors available on the DocuColor 40 is different from that of a press, the DocuColor 40 CP automatically adjusts the color so that the output falls within the range of colors a press can produce.

Several simulations are provided with the DocuColor 40 CP, and you can create additional ones by editing existing simulations with Print Calibrator. A default simulation target is speciﬁed by the administrator in Setup. You can change the default simulation using Print Calibrator.

The simulations provided with the DocuColor 40 CP are:

DIC—Japanese press standard

•

• Euroscale—European press standard

• SWOP-Coated—US press standard

• Match Copy—Bypasses calibration and produces output that matches a copy made

from the copier glass

Each of the press simulations has both a Quick and Full version. These versions correspond to the method of mapping colors from your copier’s color gamut to that of the desired press standard as follows:

• Quick—Compensates for only density (one-dimensional mapping)

• Full—Corrects for hue as well as density (four-dimensional mapping)

5-12 Advanced Print Calibrator Topics

The PPD for the DocuColor 40 CP provides placeholders for ﬁve custom simulations named Custom-1, Custom-2, and so on. These can be made available for users to select from the CMYK Simulation print option when printing a job.

You can store targets on the computer where you use Print Calibrator, on another connected disk, or on the DocuColor 40 CP disk (or all three). However, only the original simulations and ﬁve custom simulations are available to users who choose a simulation on a job-by-job basis (with the CMYK Simulation print option).

For a custom simulation intended to be available only as a CMYK Simulation setting in Setup, any name can be used. For a custom simulation intended to be available for users to choose on a job-by-job basis, the name must be “Custom-1”, “Custom-2”, and so on.

NOTE: The custom simulation names “Custom-1” and “Custom-2” appear in the users ’

CMYK Simulation settings, and users can choose them, whether or not the corresponding custom options have been created and loaded on the DocuColor 40 CP. Jobs printed with a nonexistent custom simulation fail printing and show an error.

For more information on the CMYK Simulation and CMYK Simulation Method print options, see the Printing Guide.

5-13 Using advanced simulation features

Using the Simulation Mode window

After starting Print Calibrator, choose Simulation Mode from the File menu. The Simulation Mode window has buttons for the most frequently used Print Calibrator functions. There is also a menu bar with File, Edit, Measurements, Server, and Window menus, and a status message at the bottom of the window. Functions unavailable at any particular time are dimmed and cannot be selected.

The buttons and their functions are:

•

Select Simulation—Allows you to select a simulation to work with. You must select a

simulation before editing or applying it to the DocuColor 40 CP. Below the button are the name and creation date of the currently selected simulation, which is not necessarily the default simulation on the DocuColor 40 CP.

• Edit Simulation—Allows you to view and customize the current simulation.

• Test Simulation—P rints a test page so that you can view the results of the simulation

you are currently working with.

• Set Default Simulation—Updates the default simulation on the DocuColor 40 CP.

5-14 Advanced Print Calibrator Topics

Checking the current simulation

You can use Print Calibrator to see the simulation currently selected as the default on the DocuColor 40 CP.

TO VIEW INFORMATION ABOUT THE CURRENT SIMULATION:

1. Start Print Calibrator and connect to the DocuColor 40 CP.

2. Choose Server Status from the Server menu.

The bottom section of the Server Status window displays the default simulation.

5-15 Using advanced simulation features

Editing simulations

You can edit a press simulation to meet your exact speciﬁcations. Y ou can also sav e the changes as a new simulation.

NOTE: The values in the following illustrations do not represent standard values. They

are intentionally exaggerated for example purposes.

TO EDIT A SIMULATION:

1. Start Print Calibrator and connect to the DocuColor 40 CP.

2. Choose Simulation Mode from the File menu.

3. Click the Select Simulation button.

A dialog box displays the simulations available on the DocuColor 40 CP.

4. Select a simulation and click OK.

You can use this dialog box to view or to edit simulations.

6. In the View Channels area, select the channels to edit.

7. For each color , enter a value in the Maximum Density ar eas and then pr ess T ab or Enter to adjust the endpoint of the target curve as needed.

You can enter a value from 0.1 to 3.0. The rest of the curve adjusts to make a smooth transition to the new endpoint. The

adjusted target is stored. To discard changes, reload the target from the server or from the local disk.

8. From the “Apply setting to” menu, choose the channel to adjust in the Lightness/ Darkness area of the window.

5-17 Using advanced simulation features

9. Use the Brightness menu to adjust brightness as needed.

10. Adjust the Dot Gain value as needed.

11. In the graph, click and drag points to adjust the curve as needed.

OTE: If you change a value for a color with the Brightness menu, it overrides values

set elsewhere in the dialog box.

If you use Dot Gain values, the curve is smoothed so that there are no spikes or jumps in output value.

The graph maps input percentage to output percentage in 10% increments. The points along the curve are marked so that you can adjust them.

NOTE: Y ou should adjust points on the curves after you have enter ed values in the other

areas of the window. If you change values after you have adjusted the curve on the graph, values might not be valid.

12. When you are ﬁnished, click Save and enter a name for the new simulation.

This saves the simulation to DocuColor 40 CP. Use Local to save the simulation to your computer hard disk so that you can use it again or continue editing it later.

• Give the simulation a new name. You cannot overwrite the name of an original press

target.

• Include part of the original name in the new name, for example, “SWOP-New.”

This helps you remember what the new simulation is based on.

• To allow users to print with the simulation on a job-by-job basis, you must use the

exact names “Custom-1”, “Custom-2”, and so on. Give users a description of the custom simulations because they see only the “Custom” names from the printer driver interface.

NOTE: If custom simulations are later deleted from the server, users might still select

them when they print. However, jobs printed with non-existent custom simulations will fail printing and report an error.

5-18 Advanced Print Calibrator Topics

Managing simulations

With Print Calibrator, you can back up and delete simulations. You can also set the default simulation to None.

TO BACK UP SIMULATIONS:

• Choose Backup Simulations from the Server menu to copy the simulations from the DocuColor 40 CP to your computer.

Simulations are saved in a folder called Backup in the folder where Print Calibrator is located. You can save simulations for safekeeping. You should always save simulations before updating DocuColor 40 CP system software to ensure that no custom simulations are lost.

TO DELETE CUSTOM SIMULATIONS FROM THE DOCUCOLOR 40 CP HARD DISK:

1. Choose Delete Simulation from the Server menu.

2. Select the custom simulation and click OK.

You can delete simulations to make sure no one uses the wrong simulation ﬁle. You should always use the Backup Targets command to save simulations before you delete them.
