About this document
This document is organized to supply you with key information about managing the color output of your EX Print Server.
This document covers the following topics:
• Installing and configuring ColorWise Pro Tools.
• Using Color Editor, Profile Manager, and Color Setup.
• Overview of calibration and description of how to calibrate the EX Print Server using various ColorWise Pro Tools Calibrator methods.
• Using Spot-On to manage spot colors.

N OTE : The Glossary defines words in bold, for example, output profile , that appear throughout this manual. Color terms and concepts, such as “color space,” “spot color,”
“gamut,” and “source profile,” are used throughout this manual. If you are new to desktop color, or if any terms are unfamiliar, see the Glossary .
Key features of ColorWise
ColorWise is the color management system (CMS) built into the EX Print Server and designed to provide both casual and expert users with the best color output for a variety of purposes. The ColorWise default settings provide high-quality, out-of-box color from many Windows and Mac OS applications. This allows casual users to achieve quality output without knowing about or changing any color settings on the EX Print Server.
For consistent color, calibrate the EX Print Server on a regular basis. ColorWise Pro Tools includes an easy-to-use calibrator, which allows you to calibrate using either the scanning unit that is part of the digital press or an optional spectrophotometer or densitometer
(see
ColorWise features allow you to modify printing results. Depending on your particular needs, you can:
• Set the behavior of CMYK printing to emulate DIC , Euroscale , SWOP , and other offset press standards.
• Match PANTONE and other spot colors for the best match when printing using four-color press conditions or presses with extra, custom plates.
I NTRODUCTION 9
• Select a color rendering dictionary (CRD), also called a rendering style, for RGB printing.
CRDs allow for rich, saturated printing of presentation graphics , smooth, accurate printing of photographs, and relative or absolute colorimetric rendering for specialized needs.
• Define the source of incoming RGB color data for better color conversion of RGB data with no source information.
• Determine whether RGB data is converted into the full gamut of the digital press or is first converted into the gamut of another device, such as a press standard. This feature is useful for making one device behave like another for RGB data. It also allows you to evaluate the appearance of an RGB file under different printing conditions without having to convert the RGB file to CMYK first.
ColorWise color management (ColorWise) offers an open color architecture, allowing users to customize the EX Print Server to meet new printing needs as they arise. ColorWise supports ICC profiles , which are industry standard color profiles that describe the color behavior of a device. Note that ICC specification version 4 profiles (profile version 4.2.0.0) are supported as well as version 2. Downloading ICC profiles to the EX Print Server enables the EX Print Server to simulate a custom press (or another digital press), as well as accurately print colors from a particular monitor or scanner. In addition, you can create customized ICC profiles for the digital press.
ColorWise also allows you to use any Status T densitometer by importing data in a standard
file format (see “Importing Density Measurements” on page 104). In this case, it is important
to note that the quality of the instrument used determines the quality of the calibration .

Adjusting gray balance
The AutoGray feature allows you to use the digital press’s built-in scanner as a measurement device for adjusting the gray balance of output profiles. Gray balance refers to the quality of neutral gray tones in a profile. In many cases, gray tones may contain a bluish or reddish color cast. AutoGray helps shift these tones back toward neutral grays. If you are satisfied with the gray balance of the digital press, you do not need to use AutoGray.
T O CORRECT THE GRAY BALANCE OF AN OUTPUT PROFILE
1 Start ColorWise Pro Tools and click Color Editor.
2 Choose Output from the View list.
3 Select a profile to edit and click Select.
Or, you can open the Profile Manager, select a profile, and then click Edit, which starts Color
Editor.
4 Choose Custom from the Edit Mode menu.
5 Click AutoGray.
C OLOR W ISE P RO T OOLS
6 If the output profile contains no edit points, continue to
. If the output profile contains edit points from a previous AutoGray session, choose Refine or New.
24
Refine reuses edits points from a previous session in an attempt to make them more accurate.
Refine is optional; use it only if the gray balance in your test document still needs improvements after the first AutoGray session. If two Refine applications cannot fix the situation, it is probably because your test document is not correctly addressing the output profile, or because the output profile that you are editing does not adequately describe the actual digital press and printing conditions. Applying Refine more than twice is not recommended.
New starts a new AutoGray session by first removing all edit points from a previous session.
New is recommended when you have performed more than two Refine applications.
7 If the output profile contains edit points that were entered by a user, choose Proceed to remove the points and continue with the AutoGray adjustment.
Proceed starts a fresh AutoGray session by first removing all user edit points. This is because
AutoGray cannot modify user-entered points.
8 In the Print Options dialog box that appears, choose the Input Tray to use for the measurement page.

For more information about Profile Manager, see the Profile Manager section of ColorWise
Pro Tools Help.
For more information about using Device Link Profiles, see
C OLOR W ISE P RO T OOLS 27
Setting the default profiles
Use Profile Manager to set a default RGB source profile, simulation profile, or output profile.
The default RGB source and simulation profiles that you set are applied to all print jobs sent to the EX Print Server, unless you override them using print options. The same is true of the default output profile that you set, unless you select the Use Media Defined Profile option.
The Use Media Defined Profile option indicates whether or not to automatically apply the output profile associated with the media type used in a print job. For more information, see the following section.
Using media-defined output profiles
Instead of having Profile Manager apply a default output profile to all your print jobs, you can keep the Use Media Defined Profile option selected. This option automatically applies the output profile predefined for the media type in your print job. If your job contains mixed media, this option can apply different output profiles predefined for the different media.
T O USE MEDIA DEFINED OUTPUT PROFILES
1 Start ColorWise Pro Tools and click Profile Manager.
2 Select Use Media Defined Profile in the Output bar of Profile Manager.
Changing the setting for the Use Media Defined Profile option in Profile Manager automatically changes the same setting in Color Setup. For more information, see
“Using Color Setup” on page 32.
About Device Link Profiles
The EX Print Server supports the use of Device Link Profiles. A Device Link Profile describes the conversion from one color space to another. Device Link Profiles are restrictive because they define the complete conversion from a source device to a destination device. When you print using a Device Link Profile, you do not choose a source profile or an output profile because the Device Link Profile specifies both. ColorWise supports two kinds of Device Link
Profiles: RGB source to CMYK destination and CMYK source to CMYK destination.
A Device Link Profile bypasses most ColorWise color management because the information needed to convert from the source to destination is fully contained in a Device Link Profile.
To create a Device Link Profile, use profile-generating software such as EFI Color Profiler
Suite.
N OTE : Depending on your job’s workflow, you may not need to use Device Link Profiles.
C OLOR W ISE P RO T OOLS 28
Installing Device Link Profiles
If you are an administrator, you can download Device Link Profiles to the EX Print Server using Profile Manager. You must associate a Device Link Profile with the following settings:
• An RGB Source Profile or a CMYK Simulation Profile setting and
• An Output Profile setting
The Device Link Profile is enabled when these two settings are selected.
You can enable a Device Link Profile in three locations:
• In ColorWise Pro Tools Color Setup, select the default settings for RGB Source Profile,
CMYK Simulation Profile, and Output Profile. These settings apply to all jobs unless overridden for a particular job.
• Use Expert Color Settings in the EX Print Server printer drivers to select the settings for
RGB Source Profile, CMYK Simulation Profile, and Output Profile when you print a job.
• Use Command WorkStation Job Properties to override the settings for RGB Source
Profile, CMYK Simulation Profile, and Output Profile for a specific job.

Calibrating with ColorWise Pro Tools Calibrator
ColorWise Pro Tools Calibrator allows you to calibrate the EX Print Server using the measurement method of your choice.
Changing calibration has the potential to affect all jobs for all users, so consider limiting the number of people authorized to perform calibration. Set an Administrator password to control access to calibration (see Configuration and Setup ).
N OTE : Multiple users can be connected to one EX Print Server with ColorWise Pro Tools, but only one user at a time can use Calibrator. If you try to calibrate when another user is using ColorWise Pro Tools to calibrate, an error message appears.

With the Print Pages option, print Comparison Pages showing the results of the new measurements with any profile associated with the currently selected calibration set. You can create a custom Comparison Page and save it as a PostScript or Encapsulated PostScript (EPS) file called CALIB.PS. Next, print the file to the Hold queue of the EX Print Server from your application. You can also create a CALIB.PS file by renaming any job in the Hold queue using Command WorkStation.
With the View Measurements option, you can view the current set of measurements as a table or graph that shows both the measurements and the target curves.

When more than one profile uses the same target, an additional menu called Plot Against appears in the upper-right corner of the dialog box. It lists all output profiles that use that same calibration set. Selecting an output profile from this menu displays the target curves associated with that profile. If each output profile contains a unique calibration target, the curves displayed also change when you switch profiles.
C ALIBRATION 38
Applying measurements to multiple calibration sets
Calibrator provides an option (Apply to All Calibration Sets) that allows you to copy the measurements from the calibration you are currently performing to all calibrations sets on the server. This option is only available if the EX Print Server has more than one calibration set.
If you deselect Apply to All Calibration Sets, you can choose to apply the current calibration to a selected subset of the calibration sets on the server. You specify which sets by clicking
Customize next to the Apply to All Calibration Sets option, which displays the Apply To window. Click to select or deselect individual calibration sets and then click OK.
If any of the selected calibration sets are not associated with an output profile, you receive a warning but can choose to apply the calibration measurements to that set anyway.
The calibration measurements are copied to the specified calibration sets at the end of the calibration process when you click Apply.
Restoring default calibration measurements
Use the following procedure to return to factory default calibration measurements.
T O RESTORE DEFAULT CALIBRATION MEASUREMENTS
1 In the Calibrator dialog box, click Restore Device.
2 Click OK to restore the preset default calibration set.

C ALIBRATION 39
Calibrating with ColorCal
ColorCal allows you to calibrate the EX Print Server without the use of an additional spectrophotometer or densitometer. Instead, ColorCal uses the digital press’s built-in scanner to measure toner density values.
ColorCal has the following features:
• Scanner calibration: ColorCal lets you calibrate the scanner (digital press feeder) using the
Kodak Color and Gray Scale strips.
• Measurement page: For ColorCal, square black-and-white and color patches are randomly printed on the ColorCal Measurement Page. This allows ColorCal to be less influenced by digital press conditions, providing greater accuracy in color reproduction and calibration.
N OTE : To calibrate using ColorCal, you will need the Kodak Gray Scale strip included in the customer media pack that came with your EX Print Server. You also need the Kodak Gray
Scale strip and Kodak Color Control Patches strip to calibrate the scanner of the digital press for ColorCal.
When you run ColorCal from ColorWise Pro Tools, you have the option to calibrate the digital press’s scanner before calibrating the EX Print Server itself. It is recommended to calibrate the scanner for ColorCal after maintenance or service, or whenever the digital press output has been altered.

Understanding calibration
The following sections describe important concepts and suggestions for understanding calibration.
An overview of calibration
Calibration generates curves that adjust for the difference between the actual toner densities
(measurements) and the response expected by the output profile.
• Measurements represent the actual color behavior of the digital press.
• Calibration sets are sets of measurements that combine media options provided for
Calibrator.
• Each output profile contains a calibration target that describes the expected behavior of the digital press.
After you calibrate the EX Print Server, a calibration set is stored. This calibration set is used when it is associated with an output profile. Every output profile has an associated calibration set. If you have not specified one, the calibration set associated with the default output profile is used.
If you change the calibration after a saved job has been processed (RIPped), you do not have to reprocess (reRIP) the job. The new calibration affects the job without reprocessing.
N OTE : Changing calibration has the potential to affect all jobs for all users, so consider limiting the number of people authorized to perform calibration. Set an Administrator password in EX Print Server Setup to control access to calibration (see Configuration and
Setup ).
How calibration works
Although the needs of most users are met by the default calibration set, the EX Print Server allows you to choose a calibration set to customize calibration for specialized jobs.
Calibration allows you to:
• Maximize the color reproduction capabilities of the EX Print Server.
• Ensure consistent color quality over time.
• Produce consistent output across EX Print Server servers.
• Achieve better color matches when reproducing spot colors , such as PANTONE colors or other named color systems.
• Optimize the EX Print Server for using ColorWise rendering styles (CRDs), CMYK simulations, and ICC profiles.
C ALIBRATION 55
Success in obtaining satisfactory print quality from the EX Print Server depends on many factors. Among the most important are establishing and maintaining optimal toner densities.
The density is the measure of the light absorbed by a surface. By carefully regulating toner densities, you obtain consistent printed color.
Even with a calibrated system, toner density is affected by the settings of digital press, humidity, and temperature. Density also tends to drift over time. Uneven toner density on paper affects calibration results. Regular measurement detects day-to-day variations in density, gradation, and color reproduction, and calibration corrects them.
Calibration works by creating calibration curves on the EX Print Server that compensate for the difference between actual (measured) and desired (target) density values. These calibration curves are the graphic equivalent of transfer functions, which are mathematical descriptions of changes that are made to the initial data. Transfer functions are often graphed as input or output curves.
The EX Print Server generates calibration curves after comparing measured values to the final target values for each of the four toner colors. The target values are based on the output profile specified.
Measurements
Measurement files contain numerical values that correspond to the toner density produced by the digital press when it prints solid cyan, magenta, yellow, and black, and graduated tints of those colors.
To create a measurement file, print a page of color patches. Measure the patches using a color measurement instrument connected to a computer on the network, or if it is available, the print device’s scanner. The new measurements are automatically downloaded to the
EX Print Server.
Output profiles and calibration sets
Output profiles and calibration sets define desired calibration results. One or more output profiles and calibration sets are provided with the EX Print Server. When you calibrate the
EX Print Server, select the calibration set that corresponds to the typical printing jobs at your site. This same calibration set can be associated with one or more output profiles. For more information about output profiles, see
C ALIBRATION 56
Scheduling calibration
Calibrate the EX Print Server at least once a day, depending on the volume of print jobs.
If it is very important to maintain consistent color, or your digital press is subject to wide fluctuations in temperature or humidity, calibrate every few hours. For optimal performance, calibrate whenever there is a noticeable change in print quality or printing results are not as expected.
If you must split a print job into two or more batches to print at different times, it is important to calibrate before you print each batch. You should also calibrate the
EX Print Server after digital press maintenance. However, because the digital press may be less stable immediately after maintenance, wait until you have printed approximately 50 pages before you calibrate.
N OTE : Because printed output from the digital press is very sensitive to changes in temperature and humidity, do not install the digital press near a window, in direct sunlight, or near a heater or air conditioner. Paper is also sensitive to climate changes. Store it in a cool, dry, stable environment, and keep reams sealed until they are used.
To monitor print quality, print the following color pages:
• Color Charts (from Command WorkStation or the digital press control panel)
• Color reference pages included in the User Software DVD (see pages
These pages include fully saturated color patches and pale tints of cyan, magenta, yellow, and black. Images with skin tones offer a good basis for comparison. Save and periodically compare the pages you print. If a noticeable change in appearance occurs, calibrate the
EX Print Server.
When you examine the Test Page, all color patches should be visible, even though they may be very faint in the five to two percent range. Each patch set should show uniform gradation from patch to patch as the color lightens from 100% to zero.
If the solid density patches (100% cyan, magenta, yellow, or black) look less saturated over time, show the pages to your digital press service technician to determine whether adjusting the digital press can improve output.
Checking calibration status
To verify whether the EX Print Server is calibrated, which calibration set and output profile were used, and when the digital press was last calibrated, perform the following:
• Print a Configuration page or Test Page from the digital press control panel or Command
WorkStation.
For instructions on printing the Configuration page, see Configuration and Setup .
• Select a calibration set in Calibrator. The last calibration and the user who performed it are displayed.

The Spot Color Matching print option automatically matches spot colors with their best
CMYK equivalents so that spot colors can be simulated using the CMYK toner of the digital press. However, you may want to adjust the default CMYK equivalents to achieve a better match for your specific printing conditions. You can modify spot colors using Spot-On.
In addition to managing “named” colors, Spot-On allows you to create a list of “substitute” colors. These are colors that, when called for in a document by their RGB or CMYK values, are substituted with a different color having the CMYK values from the Spot-On color dictionary. This permits exact color control and overrides individual RGB and CMYK colors.
Using Spot-On
Spot-On allows you to adjust and manage lists of spot colors and their CMYK equivalents.
The matching lists of spot colors and CMYK values are known as Spot Color Dictionaries.
Spot-On allows you to maintain multiple Spot Color Dictionaries for each output profile on the EX Print Server.
N OTE : To use the Spot-On features with named colors, you must enable the Spot Color
Matching print option. For more information about this option, see
N OTE : Spot colors identified by names are printed with their defined CMYK values. The edits to the output profile made with Color Editor do not affect how spot colors print.
Some Spot-On features require that a job be displayed with correct colors on your monitor.
To display the colors correctly on your monitor, you must set up the monitor display according to the manufacturer’s recommendations, and specify the correct monitor profile for your monitor.
Specify the following settings for the monitor display:
• At the monitor: Brightness, Contrast, and Color Temperature
• From the control panel of the operating system: Resolution, Refresh rate, and Number of colors
For more information about setting up your monitor and the monitor profile, see the documentation that accompanies the monitor.
N OTE : The edits to a job made with the color adjustment features in ImageViewer affect all colors in the job, including spot colors. For more information about ImageViewer, see
Graphic Arts Package .
S POT -O N 58
Starting Spot-On
To use Spot-On, you must specify the output profile associated with the Spot Color
Dictionary that you want to edit.
If you select Output profile X and redefine PANTONE 123 from 30%M to 50%M using
Spot-On, you will get 50%M when you print a job with Output profile X. If you print a job with Output profile Y, you will get the original value. If you select Output profile X and create a custom color named “My Purple” and define it as 80C 40M, ColorWise automatically calculates the Lab values using Output profile X and creates new CMYK values for use with
Output profile Y.
N OTE : The EX Print Server allows only one user to connect to Spot-On at a time.

Working with existing colors
Spot-On allows you to view and manage existing groups of colors on the EX Print Server and search for a particular color in the Spot-On list.
Color groups in the Spot-On window appear in order of their priority. Highest priority is assigned to color groups at the top of the list. For instance, if two colors from two different color groups have the same name, the EX Print Server uses the color from the higher group and disregards the other color. By managing the priority of colors in this way, you can maintain several CMYK variants for the same spot color.

3 To update the center patch to a neighboring color that more closely matches the target, click the corresponding neighbor patch.
Neighboring patches represent variations from the center patch and can be selected if they offer a closer match to the desired color. Clicking one of these patches updates the center patch to the new color and provides a new selection of neighboring colors. These patches are either lightness or saturation neighbors, depending on the option you choose in the following step.
N OTE : When you select certain colors, an exclamation point icon may appear in the upper-right corner of the dialog box. This icon indicates that one or more colorants have reached their maximum values.
4 Use the following techniques to control how neighboring color patches are generated:
Select Lightness or Saturation in the Color Directions Legend.
Lightness generates neighbor patches based on darker to lighter shades of the original color.
This variation is displayed from left to right, with the original color remaining in the center of the middle group.
Saturation generates neighbor patches based on less saturated to more saturated variations of the original color. This variation is displayed from left to right, with the original color remaining in the center of the middle group.
Choose a setting from the Color Spacing menu to control the closeness of the neighbor patches.
A higher setting generates neighbor patches that differ more noticeably from the center color.
As you get closer to your target color, reduce the color spacing to a smaller value.
Select Monitor Compensation to simulate how all the on-screen color patches will appear when printed on paper.
This simulation depends on the monitor profile that has been configured for your monitor.
To specify the monitor profile, choose Preferences from the Edit menu in the Spot-On main window.

Principles for Substitute Colors
In setting the values for Substitute Colors, keep in mind the following principles.
Tolerance range
The accuracy of the substitute color is affected by various elements, such as applications, operating systems, printer drivers, and distilling processes. To accommodate the “errors” that occur because of the rounding rules between the numbers entered by users and the numbers received by the EX Print Server, the options of the small and large tolerance ranges are provided for color substitution.
The following table provides Small and Large substitution tolerance ranges for each color mode.

N OTE : Values for tolerance ranges are approximate.
• CMYK (0-100%)
– Small: A substitute color replaces any color that falls within the nearest +/- 0.25% of the color value entered.
– Large: A substitute color replaces any color that falls within the nearest +/- 0.5% of the color value entered.
• RGB (Device Code 0-255)
– Small: A substitute color replaces any color that falls within the nearest +/- 0.25 of the color value entered.
– Large: A substitute color replaces any color that falls within the nearest +/- 1 of the color value entered.
• RGB (0-100%)

Color substitution
A color substitution takes place when a substitute color is defined with a different set of
CMYK values for the same value-name as the original color.
The following color examples show how a substitution works.
• Original color: <100, 0, 0, 0> for the CMYK values (cyan)
• Substitute 1: <0, 100, 100, 0> (red)
• Substitute 2: <100, 0, 100, 0> (green)
N OTE : In the examples, the extreme values and terms “red” and “green” are used for illustrative purposes only. In practice, color substitution is not used for extreme color shifts.
The following table shows color substitution with different sets of CMYK values assigned to the same original color.
Substitution value-name

CMYK values
<100, 0, 0, 0>
<100.0c, 0.0m, 0.0y, 0.0k> <0, 100, 100, 0>
<100.0c, 0.0m, 0.0y, 0.0k> <100, 0, 100, 0>
Before substitution
— cyan cyan
After substitution
— red green
Priority scheme
If two substitute colors are defined with the same value-names, but with different sets of
CMYK values and different tolerance ranges, Spot-On resolves the priority of substitution according to the order of color in the group.
Spot-On process color substitution is based on the order of color in the group. The color entries at the top of the list have priority over the colors at the bottom of the list. Spot-On scans the list from top to bottom and processes substitution in linear order. When a color is remapped, it is not overridden by any subsequent substitution call.
The following color examples show how the priority scheme works.
• Original color: <100, 0, 0, 0> for the CMYK values (cyan)
• Substitute 3: <0, 100, 100, 0> (red) with a small tolerance
• Substitute 4: <100, 0, 100, 0> (green) with a large tolerance
N OTE : In the examples, the extreme values and terms “red” and “green” are used for illustrative purposes only.
Order of the colors
• Case 1: Substitute 3 (red) is higher than Substitute 4 (green) in the list.
• Case 2: Substitute 4 (green) is higher than Substitute 3 (red) in the list.

<100, 0, 100, 0>
<0, 100, 100, 0> cyan cyan red
(see the following) green
(see the following)
Substitute 3 and Substitute 4 have the same value-names, but depending on their order in the list, Spot-On produces different results.
• In Case 1, Substitute 3, red, is given higher priority because it is higher in the list. All occurrences of the original color, cyan, within the Small tolerance range are substituted with red. Occurrences of cyan within the Large tolerance range but not within the Small tolerance range are substituted with Substitute 4, green.
• In Case 2, Substitute 4, green, is given higher priority because it is higher in the list.
Substitute 3, red, can only substitute for occurrences of the original color, cyan, within the
Small tolerance range, and those occurrences have already been substituted with green.
Therefore, no substitution with red takes place.
Uploading and downloading a substitute color group
Like named color groups, you can upload or download a substitute color group as an ICC profile. The substitute color definitions are saved with private tags as part of an ICC profile, allowing you to export the Substitution Group definitions between multiple print servers.
However, Substitution Group definitions are recognized only by the EX Print Server with
Fiery Graphic Arts Package, Premium Edition enabled.

Managing color on the EX Print Server
To modify EX Print Server printing behavior, do any of the following:
• Specify ColorWise options for an individual print job using the menus that appear in the printer driver.
• Specify most ColorWise options as server defaults from Color Setup in ColorWise Pro
Tools (see
page 32 ). You can also set default values from EX Print Server Setup, as
described in Configuration and Setup . The defaults apply to all subsequent print jobs unless you override them.
• Specify ColorWise options, particularly default ICC profile settings and calibration options, from ColorWise Pro Tools. These options include default Simulation Profile (see
), Simulation Method (see
), default Source Profile (see page 93
), RGB
Separation (see
), and associated calibration set (see page 35
).
Applications allow you to generate color data for the EX Print Server in many different color spaces . The most common type of color data produced from office applications is RGB , while prepress applications generally produce CMYK data. Desktop applications also generate spot colors , such as PANTONE colors. To complicate matters, a single page may contain a mix of RGB, CMYK, and spot colors. The EX Print Server allows you to control the printing of mixed-color documents with features that apply specifically to RGB, CMYK, or spot color data.
The following diagram illustrates the print options in the EX Print Server color management process that affect color data conversions. You can access these print options when you send a print job to the EX Print Server. Most of these options and settings are described in subsequent sections of this chapter.

RGB Source Profile is the only color option that applies strictly to RGB color data. The other options that affect RGB color also affect the more rarely used Lab, XYZ, and other calibrated color spaces.
C OLOR W ISE P RINT O PTIONS 83
N OTE : With PostScript 3, a PostScript job can include calibrated CMYK (or
CIEBasedDEFG) data. The Rendering Style print option, which normally affects only RGB data, affects calibrated CMYK data as well. The RGB Source Profile setting does not affect calibrated CMYK data.
ColorWise print options
The following sections provide detailed explanations of the ColorWise print options and how these options affect print jobs.
N OTE : For information about the following print options, see Graphic Arts Package .
• Halftone Simulation
• Paper Simulation
• 2-Color Print Mapping
Auto Trapping
Trapping is a technique where the size of objects is modified so that colors printed next to each other overlap slightly, to prevent white spaces between two colors. These white spaces, or
“halos,” can be caused by factors such as misregistration, the physical properties of the toners, and the stiffness of the media. This illustration shows the same image with and without trapping.
If you enable the Auto Trapping option, trapping is applied to all the objects in a job.
The EX Print Server is shipped with trapping values that are optimized for a Fiery-driven print device using regular paper. If these values do not provide the results necessary for the media that you use, and if Fiery Graphic Arts Package, Premium Edition is configured on the
EX Print Server, you can modify the values to meet your requirements. For more information, see Graphic Arts Package .
C OLOR W ISE P RINT O PTIONS 84
Black Detection
The Black Detection option allows you to specify whether or not to detect black-and-white pages before printing your job. To use this option, set Color Mode to Standard Color or
Expert Color.
• Off : Select Off if your job consists of black-only text pages combined with a significant number of color pages.
• On : Select On if you are printing a predominantly black-and-white job. Black-and-white only pages will print with the proper billing information.
N OTE : This feature is not available with the PCL driver.
Black Overprint
The Black Overprint option allows you to specify whether or not black text or black text and graphics, defined as RGB=0, 0, 0, or as CMYK=0%, 0%, 0%, 100%, overprints colored backgrounds.
• Text: Black text overprints colored backgrounds, eliminating white gaps and reducing the halo effect or misregistration of colors. You can choose this setting only if the Black Text/
Graphics option is set to Pure Black On.
• Text & Graphics: Black text and graphics overprint colored backgrounds, eliminating white gaps and reducing halo effects or misregistration of colors. You can choose this setting only if the Black Text/Graphics option is set to Pure Black On.
• Off: Black text or text/graphics knocks out colored backgrounds.
N OTE : Before sending the print job to the digital press, PostScript applications may perform their own black overprint conversions.
One example of how you might use this setting is a page that contains black text on a light blue background. The background blue is CMYK=40%, 30%, 0%, 0%. The black text is
CMYK=0%, 0%, 0%, 100%.
• With Black Overprint set to Text or Text & Graphics, the final text or text/graphic portions of the page are overprinted, or combined with the underlying color. Black colors generated by applications (for example, RGB=0, 0, 0 or CMYK=0%, 0%, 0%, 100%) are printed using the black toner. This means that black text and line art does not exhibit halftone artifacts (as long as the digital press is calibrated correctly). No transition in cyan and magenta toners occurs. The quality of the output is improved, because it does not show artifacts near the edges of the text defined in the RGB color space (RGB=0, 0, 0).
• With Black Overprint Off, the border of the text or text/graphics is on an edge that has cyan and magenta toners on one side (outside the text) and black toner on the other side
(inside the text). This transition may cause visible artifacts due to the practical limitations of the digital press.
C OLOR W ISE P RINT O PTIONS 85
N OTE : Setting Black Overprint to Text/Graphics allows black text or graphics to overprint
color backgrounds (see “CMYK Simulation Method” on page 88).
N OTE : The reproduction of CMYK components is affected by the CMYK Simulation setting and calibration curve when CMYK is not 0%, 0%, 0%, 0%.
N OTE : This feature is not available with the PCL driver.
Color
RGB=0,0,0
(all other RGB values are unaffected by the Black Text/
Graphics setting)
Black Text/Graphics
The Black Text/Graphics option affects black text and vector graphics . Under most circumstances, set this option to Pure Black On. When Black Text/Graphics is set to Pure
Black On, black colors generated by applications (for example, RGB=0, 0, 0 or CMYK=0%,
0%, 0%, 100%) are printed using black toner only. The black text and line art do not exhibit halftone artifacts (as long as the digital press is calibrated correctly) and are not misregistered, since one toner is used. In addition, this setting eliminates blasting . This option must be set to Pure Black On if you want to set the Black Overprint option to Text or Text/Graphics.
For some jobs, it is preferable to set this option to Normal, for example, if the page includes gradient fills that use black. The following table describes the behavior of the Black Text/
Graphics option with black data defined in different color spaces.
N OTE : Use the Black Text/Graphics option only when printing composites, not when printing separations.
Black Text/Graphics = Normal
RGB=0,0,0 is printed according to the definition for RGB=0,0,0 in the output profile. This may be a rich black using all toners if the output profile specifies a rich black, or may be K-only if the output profile specifies K-only for
RGB=0,0,0. The output is affected by the calibration curve.
Black Text/Graphics = Pure Black On or
Rich Black On
RGB=0,0,0 is printed as K-only, using the black toner (Pure Black On) or 100% K plus 50%
Cyan (Rich Black On) using black and cyan toners. All other RGB values are unaffected by the Black Text/Graphics setting.

If CMYK Simulation Profile is set to a specific profile, CMYK=0%,0%,0%,100% prints as
K-only and the amount of black toner is limited by the simulation profile and the calibration curve.
Setting CMYK Simulation to ColorWise Off disables the simulation profile and the calibration curve. In this case, the black toner is not limited by the calibration curve.

Method settings. All other CMYK values are unaffected by the Black Text/Graphics setting.
Setting CMYK Simulation to ColorWise Off disables the simulation profile and the calibration curve. In this case, the black toner is not limited by the calibration curve.
Standard spot color processing
N OTE : PostScript applications, such as QuarkXPress, may convert elements defined as
RGB=0, 0, 0 to four-color CMYK black before sending the job to the EX Print Server. These elements are not affected by the Black Text/Graphics option. For more information, see Fiery
Color Reference . Also, black text and line art defined as RGB=0, 0, 0 in office applications, such as Microsoft Word, are converted to single-color black (CMYK=0%, 0%, 0%, 100%) by the Microsoft PostScript 3 printer driver for Windows 2000/XP/Server 2003. To print this single-color black at the maximum toner density of the digital press, set Black Text/Graphics to Pure Black On.
C OLOR W ISE P RINT O PTIONS 87
CMYK Simulation Profile
The CMYK Simulation Profile print option allows you to print press proofs or simulations.
This setting specifies the offset press standard or other color printing device that you want to simulate. This option affects CMYK data only.
N OTE : If a document contains an embedded CMYK profile, the embedded profile is applied to CMYK data and the CMYK Simulation Profile option is ignored.
With Windows printer drivers, you can also view an unlimited number of custom Full simulations created using ColorWise Pro Tools. On Mac OS computers, you can view up to
10 Full custom simulations. The number of custom simulations is limited by the available disk space on the EX Print Server.
If you are printing with the PostScript driver and have Two-Way Communication enabled, the name of each downloaded or custom profile appears in the CMYK Simulation Profile menu. If Two-Way Communication is not enabled, downloaded or custom profiles appear as
Simulation-1 through Simulation-10. For more information about Two-Way
Communication, see Printing from Windows or Printing from Mac OS.
The None setting sends your original CMYK data to the digital press in its calibrated state, without conversions to simulate another printer. The ColorWise Off setting sends your original CMYK data to the digital press in an uncalibrated state, without conversions to simulate another printer. This setting is not generally recommended, unless you want to bypass the ColorWise conversion and use another color management system.
The CMYK Simulation Profile setting you specify depends on the press standard for which the CMYK data was separated.
• For images that were separated using a custom separation (such as a separation produced with an ICC profile), choose the corresponding profile on the EX Print Server with the
CMYK Simulation Profile setting.
• For images that were separated for SWOP , choose SWOP as the CMYK Simulation Profile setting.
To properly simulate a printed image that was separated using an ICC profile, the same profile must be present on the EX Print Server. For more information about downloading ICC profiles to the EX Print Server, see
N OTE : This feature is not available with the PCL driver.
C OLOR W ISE P RINT O PTIONS 88
CMYK Simulation Method
The CMYK Simulation Method allows you to define your preferred CMYK-to-CMYK conversion technique.
• Quick applies one-dimensional transfer curves to adjust output densities in the cyan, magenta, yellow, and black channels. This technique leads to eye-pleasing color output from your digital press because pure primary colors are not “contaminated” by other colorants . While it is the fastest simulation method and perfect for drafts, avoid using it for final documents that are used as press proofs. Other techniques offer the color simulation accuracy required by proofing applications.
• Full (Source GCR) provides a complete and accurate simulation based on colorimetric transformations. Hues are preserved, even for primary colors. The Gray Component
Replacement (GCR) level that was specified in the original (source) document is also preserved for K-only text and graphics. Processed black expressed in CMY is reproduced using CMY toner. Full (Source GCR) is recommended for the highest quality press proofing applications.
• Full (Output GCR) is a complete and accurate simulation method based on colorimetric transformations. Hues are preserved, even for primary colors. With this method, the Gray
Component Replacement (GCR) level that was specified in the original document is not preserved. Instead, all CMYK data is reseparated using the GCR level specified by the output profile. This simulation technique is similar to traditional ICC color matching methods and is more appropriate than Full (Source GCR) for full color printing designed for the press, but reproduced on your digital press.
N OTE : When you specify Pure Black On for Black Text/Graphics and Full (Output GCR) for
CMYK Simulation Method, the black text and graphics in your document are printed with
100% black-only toner.
N OTE : This feature is not available with the PCL driver.
C OLOR W ISE P RINT O PTIONS 89
Combine Separations
The Combine Separations setting specifies how to print separated CMYK data. It supports:
Cyan, Magenta, Yellow, Black, and one or more spot colors.
With the Fiery Graphic Arts Package, Premium Edition, you can combine an unlimited number of spot color separations along with the CMYK separations. For more information, see Graphic Arts Package .
• Off prints each separation individually.
• On combines separations as a single, composite-color document, and automatically makes the settings for the following print options: Color Mode (CMYK), Black Text/Graphics
(Normal), Black Overprint (Off ), and Spot Color Matching (Off ).
The results of combining the multiple plates are predictable and accurate, regardless of the original application used. This feature also fully supports DCS 2.0 file formats when included in a PostScript print job from a page layout application.
The following applications have been tested with Mac OS and Windows for compatibility with the Combine Separations option:
• Adobe Illustrator
• Adobe InDesign
• Adobe PageMaker
• Adobe FreeHand
• QuarkXPress
For information about using the Combine Separations option with applications such as
Photoshop, see Fiery Color Reference.
N OTE : This feature is not available with the PCL driver.
C OLOR W ISE P RINT O PTIONS 90
Composite Overprint
When overlapping objects are printed, the foreground object can either overprint or knock out the background object. With overprinting, the color of the background object shows through the foreground object where they overlap, and the resulting color is a combination of the colors of the two objects. With a knock-out, the foreground object hides the background object where they overlap.
The Composite Overprint print option allows you to print overprinted objects as specified in the source file. By default, the Composite Overprint print option is off and overlapping objects print as knockouts.
N OTE : The Composite Overprint option does not overprint the foreground object if it is an
RGB object.
The Composite Overprint print option is supported for PostScript and PDF jobs produced by the following applications:
• Adobe Acrobat
• Adobe Illustrator
• Adobe InDesign
• Adobe FreeHand
• QuarkXPress
• CorelDRAW
The 2-Color Print Mapping option is ignored when Composite Overprint is enabled.
A job with more than 32 spot colors may not print as expected.
C OLOR W ISE P RINT O PTIONS 91
Output Profile
Because the output profile is applied to all data in the print job, make sure the profile you select is the right one for your job. The default output profile consists of a profile for your digital press that describes its color characteristics and a calibration target that describes the expected behavior of the digital press.
Use the ColorWise Pro Tools Profile Manager to download your own output profile to the
EX Print Server (see “Using Profile Manager” on page 26). Downloaded output profiles are at
first associated with the calibration target that is tied to the default output profile. You can edit calibration target D-Max values separately.
If you are printing with the PostScript driver and have enabled Two-Way Communication, the name of each downloaded or custom profile appears in the Output Profile menu. If Two-
Way Communication is not enabled, downloaded or custom profiles appear as Output-1 through Output-10 and the Use Server’s Default setting appears as a selection. Select the Use
Server’s Default setting to use the default Output Profile set in Color Setup. For more information about Color Setup, see
“Using Color Setup” on page 32. For more information
about Two-Way Communication, see Printing from Windows or Printing from Mac OS .
Select the Use Media Defined Profile setting to automatically apply the output profile associated with the media type used in a print job rather than setting a specific output profile.
For more information, see “Using media-defined output profiles” on page 27.
N OTE : This feature is not available with the PCL driver.
Print Gray using Black Only
When Print Gray using Black Only is enabled, any gray (any color where R=G=B or C=Y=M, or any K-only color) in a job is printed using only black toner instead of processed black.
You can choose to apply the Print Gray using Black Only option to either Text and Graphics or to Text, Graphics, and Images.
The following limitations apply:
• The Print Gray using Black Only option has no effect on a job that is pre-separated, except that if Print Gray using Black Only (CMYK) is off, each separation, which is a grayscale image, is printed in a 4-color gray.
• If CMYK Simulation Method is set to Full (Source GCR) or Quick, the Print Gray using
Black Only (CMYK) setting does not affect the output.
• If RGB Separation is set to Simulation, the Print Gray using Black Only (RGB) option is disabled. Likewise, if the Print Gray using Black Only (RGB) option is enabled, you cannot set RGB Separation to Simulation.
• If Black Text/Graphics is set to Pure Black On or Rich Black On, it takes precedence over
Print Gray using Black Only for 100% black text and graphics.
• If a gray is specified as a spot color, the Print Gray using Black Only option does not affect that gray.
C OLOR W ISE P RINT O PTIONS 92
Rendering Styles
The Rendering Style option specifies a CRD for color conversions. To control the appearance of images, such as prints from office applications or RGB photographs from Photoshop, select the appropriate rendering style. The EX Print Server allows you to choose from the four rendering styles currently found in industry standard ICC profiles.
EX Print Server rendering style
Photographic: Typically results in less saturated output than presentation rendering when printing out-of-gamut colors. This style preserves tonal relationships in images.
Presentation: Creates saturated colors but does not match printed colors precisely to displayed colors.
In-gamut colors, such as flesh tones, are rendered well. This style is similar to the Photographic rendering style.
Relative Colorimetric: Provides white-point transformation between the source and destination white points. For example, the bluish white color (gray) of a monitor is replaced by paper white. This style avoids visible borders between blank spaces and white objects.
Absolute Colorimetric: Provides
no white point transformation between the source and destination white points. For example, the bluish white color (gray) is not replaced by paper white.
Best used for
Photographs, including scans and images from stock photography
CDs and digital camera images.
Artwork and graphs in presentations. In many cases, this style can be used for mixed pages that contain presentation graphics and photographs.
Equivalent ICC rendering style
Image , Contrast , and Perceptual
Saturation ,
Graphics
Advanced use when color matching is important, but you prefer white colors in the document to print as paper white. This style may also be used with PostScript color management to affect CMYK data for simulation purposes.

C OLOR W ISE P RINT O PTIONS 93
RGB Separation
The RGB Separation option determines how RGB colors (as well as Lab and XYZ colors) are converted to CMYK. The name of this option is meant to be descriptive, because the option defines the color spaces that are used by the EX Print Server to “separate” the RGB data into
CMYK values.
The two choices available for this option determine whether RGB data is converted into the full gamut of the digital press ( output ) or is first converted into the gamut of another digital printer or press standard ( simulation ). This feature helps make one device behave like another for RGB data. For example, if a high-quality ICC profile is available for another print device, the digital press can simulate the behavior of that device.
RGB Separation is also useful for prepress applications. For example, it allows you to experiment with the appearance of an RGB scan under different press printing conditions, without having to convert the RGB data to CMYK data for each condition. When the desired printing condition is found, convert the file to CMYK, using the same CMYK simulation profile that you used during the experimentation.
N OTE : Use the RGB Separation print option in conjunction with the Output Profile or
CMYK Simulation Profile print options.
• Output converts all RGB colors into the CMYK color space of your digital press (when set to the printer’s default), or a customized CMYK color space for your digital press
(when set to Output 1-10).
• Simulation converts all RGB colors into the CMYK color space for a specified simulation
(select the desired simulation with the CMYK Simulation Profile print option).
RGB Source Profile
The RGB source profile setting allows you to define the characteristics of the RGB data in your document so that the appropriate color conversion occurs on the EX Print Server.
Commonly used monitor color spaces are available from the printer driver and the
EX Print Server. For others, use ColorWise Pro Tools Profile Manager to download custom monitor or scanner profiles.
When you specify a setting other than None for the RGB Source Profile, the EX Print Server overrides source color space definitions or profiles that other color management systems may have specified. For example, if your document contains an embedded RGB profile, the RGB
Source Profile setting overrides it. In cases where you do not want this setting to override another specified source color space, choose None.
When you specify a setting other than None, because the color space definitions are overridden, the output from the EX Print Server is consistent across platforms. The
EX Print Server RGB Source Profile options are as follows:
• EFIRGB specifies an EFI-defined color space recommended for users who have no detailed information about their RGB data.
C OLOR W ISE P RINT O PTIONS 94
• sRGB (PC) specifies the definition of a Windows computer monitor profile used as the default.
• Apple Standard specifies the definition of a Mac OS computer monitor profile used as the default.
• Adobe RGB (1998) is an Adobe-defined color space, used in pre-press as the default working space in Photoshop 5.
• ECI-RGB is the European Color Initiative (ECI) recommended space for use as an RGB working color space and color data exchange format for ad agencies, publishers, reproduction and printing houses.
• Fiery RGB is an EFI-defined color space recommended for users of office applications. This color space is similar to EFIRGB but is larger and can provide a more desirable blue output.
• Sources 1-10 specify the definitions you download as RGB source profiles.
If you are printing with the PostScript driver and have enabled Two-Way Communication, the name of each downloaded profile appears in the RGB Source Profile setting menu. If
Two-Way Communication is not enabled, downloaded profiles appear as Source-1 through Source-10. For more information about Two-Way Communication, see Printing from Windows or Printing from Mac OS .
• None instructs the EX Print Server to allow the RGB sources you defined elsewhere, such as in the application, to be used. When you set RGB Source to None, the appearance of colors is not independent of the file type. For example, RGB EPS files looks different from
RGB TIFF files.
With RGB Source set to None, PostScript RGB data that contains a source color space definition is converted using the CRD specified by the Rendering Style option (see
“Rendering Styles” on page 92). Non-PostScript RGB data and PostScript RGB data that
does not contain a source color space definition are converted using a general undercolor removal (UCR) conversion method.
N OTE : This feature is not available with the PCL driver.
C OLOR W ISE P RINT O PTIONS 95
Spot Color Matching
The Spot Color Matching option provides automatic matching of spot colors with their best
CMYK equivalents.
• On: The EX Print Server uses a built-in table to generate the closest CMYK matches of spot colors your digital press can produce. (New tables are generated when you add new output profiles.)
With Spot-On, the EX Print Server uses the CMYK matches determined through Spot-
).
• Off: The EX Print Server processes the spot color as CMYK data and uses CMYK equivalents defined by the spot color manufacturer, such as PANTONE. These are the same CMYK equivalents used by applications that include spot color libraries.
N OTE : Spot colors that are not included in the built-in table are treated as CMYK.
For jobs that include spot colors, set Spot Color Matching to On unless you are printing press simulations. In that case, set Spot Color Matching to Off and choose the appropriate CMYK
Simulation setting (see
For a PDF job that includes spot colors that are not included in the built-in table, setting Spot
Color Matching to On retains the original spot colors. The EX Print Server references the built-in table to generate the closest CMYK matches of the original spot color.
N OTE : Use Spot Color Matching only when printing composites, not when printing separations.
Spot Color Matching and the PANTONE Coated Color Reference
The PANTONE Coated Color Reference prints differently depending on the Spot Color
Matching setting (see Fiery Color Reference ).
• On: The EX Print Server uses a built-in table or, with Spot-On, the Spot-On color dictionaries to generate the best matches for the PANTONE colors that your digital press can produce. The PANTONE number is displayed below each swatch.
For more information about Spot-On, see
• Off: The EX Print Server prints swatches using the CMYK values recommended by
Pantone, Inc. (and used by applications that provide PANTONE color libraries). The
CMYK values used to generate the color, as well as the PANTONE number of the color, are printed below each swatch. These CMYK values are printed through the selected
CMYK Simulation and Output Profile settings.
N OTE : This feature is not available with the PCL driver.
C OLOR W ISE P RINT O PTIONS 96
Substitute Colors
Spot-On allows you to create a list of substitute colors. These are colors that, when called for in a document by their RGB or CMYK values, are substituted with a different color having the CMYK values from the Spot-On color dictionary. This permits exact color control and overrides individual RGB and CMYK colors.
To enable substitute colors for a job, select the Substitute Colors option.
For more information about creating and using substitute colors, see
Substitute Colors” on page 71.
N OTE : This feature is not available with the PCL driver.
Use PDF/X Output Intent
PDF/X is a subset of the PDF specification. PDF files can contain a variety of elements (text, graphics, even animations) and it is not always obvious how these elements should be displayed or printed. PDF/X was designed with focus on high quality printing. It excludes the use of PDF features that are not appropriate for graphic arts and adds features that prevent ambiguities related to printing. A PDF/X compliant document contains embedded information about the intended printing conditions for the document.
The Use PDF/X Output Intent option, when enabled for a PDF/X job, specifies that the
EX Print Server use the PDF/X output intent embedded in the PDF/X document. Typically, whether you use this option depends on whether you are using the EX Print Server for proofing or for production (final) printing.
Prints for proofing are expected to look exactly like the output of the final production device, no matter the capabilities of the EX Print Server or the digital press. For instance, when proofing Newsprint, you want the color gamut of the digital press to be very limited compared to its capabilities. In production, you usually want to maximize the use of the digital press gamut by applying specific color features of the EX Print Server or the digital press. Even in production, however, you might choose to limit the color gamut in order to achieve consistency in the color produced by different devices.
The Use PDF/X Output Intent option only affects PDF/X files (conforming to the PDF/X-3 or PDF/X-1a standard). It has no effect on non-PDF files or PDF files that are not PDF/X compliant. Profiles specified by PDF/X files must be embedded in the files, not referenced from an external locations.
N OTE : With the Fiery Graphic Arts Package, Premium Edition option, you can use a Hot
Folders filter to determine if a PDF file is PDF/X compliant. For information about this Hot
Folders filter, see Graphic Arts Package .
C OLOR W ISE P RINT O PTIONS 97
When Use PDF/X Output Intent is enabled and no other setting conflicts, the
EX Print Server processes a PDF/X compliant file in a way that produces results defined by the intents and source color spaces embedded in the file. The EX Print Server ignores the
CMYK Simulation Method and CMYK Simulation Profile options. The rendering intents in the PDF/X file are used and the printed output is limited to the color gamut specified by the output profile embedded in the file.
When Use PDF/X Output Intent is disabled, the EX Print Server ignores the PDF/X output intent.
You can specify the Use PDF/X Output Intent print option for a job in Job Properties in
Command WorkStation but not when you print from the print driver. PDF/X files can be imported directly to the EX Print Server using Command WorkStation or Hot Folders, but printer drivers always convert PDF before sending a job to the EX Print Server. The Use
PDF/X Output Intent option does not appear in the printer driver.
When you enable Use PDF/X Output Intent, you must set the RGB Source Profile option to
None so that the rendering intent embedded in the PDF/X file will be used. The Use PDF/X
Output Intent and RGB Source Profile options are both in the Expert Color Settings window accessed from the Color icon in Job Properties.
Printer drivers and print options
The printer driver writes a PostScript file containing the instructions generated by your application and the settings for the ColorWise print options you selected. The printer driver then sends the PostScript file to the EX Print Server. The EX Print Server performs PostScript processing and color conversions and sends raster color data to the digital press.
Setting print options for Windows
This section explains how to set color management print options with the Adobe and
Microsoft PostScript printer drivers for Windows, PostScript 3 printer drivers that take full advantage of the color features of the EX Print Server.
Before you proceed, do the following:
• Install the printer driver and the EX Print Server PPD (see Printing from Windows ).
• Set up the EX Print Server for printing (see Printing from Windows ).
N OTE : The following illustrations and instructions do not apply to all applications. Many applications, such as Adobe PageMaker, Photoshop, Adobe Illustrator, QuarkXPress, and
CorelDRAW, have other color management options in addition to those presented in the printer driver. For information about specific applications, see Fiery Color Reference .
Use the following procedure to set the color options for Windows computers.

Using Expert Color Settings to enable Device Link Profiles
When you print a job, you can enable Device Link Profiles by using the EX Print Server printer driver if you have Two-Way Communication enabled. When you enable a Device
Link Profile, you will be able to see the Device Link Profile in use in Expert Color.
N OTE : If you do not have Two-Way Communication enabled, and you select an RGB Source
Profile and Output Profile that corresponds to a Device Link Profile, the Device Link Profile will be activated, although you will not see the Device Link Profile in use in Expert Color.
For information about installing and assigning Device Link Profiles, see

This chapter describes Simple ASCII File Format (SAIFF), which you can use to import density measurements from measurement devices into ColorWise Pro Tools Calibrator. To use your own measurement data from an alternate measurement instrument, rather than make measurements directly in Calibrator, record your individual readings in a text file, structured as described in this chapter. You can then import the data into Calibrator by clicking From File under Get Measurements in the Calibrator main window.
Simple ASCII Import File Format
This format describes Status T measurement data for import into the ColorWise Pro Tools
Calibrator. The three possible file formats are:
• 1D Status T density for EFI 21 patch page
• 1D Status T density for EFI 34 patch page
• 1D Status T density for other pages (maximum of 256 patches per ink)
The file format is ASCII and has no tabs. A single space or multiple spaces are used as delimiters. Blank lines are not allowed. Each line in the file represents four patches
(C, M, Y, K) of a specific ink value. Comments may be on any line in the file. Comment lines must start with a pound sign (#) followed by a space. (A line with a pound sign followed by any character other than a space has been reserved.) Comments must be on a line by themselves.
Each line of data contains five values. The first number is the sequential patch number (for
EFI 21 and EFI 34 pages) or the ink value percentage (for other pages). The four values that follow are the density values of C, M, Y, and K of the corresponding patch. Lines are ordered either by increasing sequential patch numbers, or by increasing the ink percentage.
For Windows computers, the file extension must be .cm0 or cm1. For Mac OS computers, the file type must be ‘TEXT’.
Measurement data in EFI 21 and EFI 34 are paper-relative. For other pages, if the first line corresponds to zero ink value, the Calibrator assumes that the measurement data is absolute and adjusts it to become paper-relative by subtracting the density values of the first line from the remaining patches.
