1.1 What is ColorPro ?
™
®
™
Welcome to ColorPro —a full feature color solution for the Harlequin MultiRIP .
ColorPro together with SetGoldPro™ profile making software is Global Graphics’ color science solu‐
tion for ensuring color quality and accuracy for proofing and emulation. ColorPro provides the larg‐
est realizable color gamuts for the final print market and allows greater accuracy than would be possible using standard profiles.
Harlequin ColorPro embraces open systems, industry standards and device‐independent color sci‐
ence, and is able to make full use of them. If you have ICC profiles with which you already achieve good results, you can use these profiles with ColorPro. You should however be aware that ColorPro contains color science that is optimized for the Harlequin MultiRIP and is easily utilized with the introduction of SetGoldPro.
Note: The ICC profile format is specified by the International Color Consortium (http://www.color.org/), established in 1993, has the charter for creating and promoting the standard‐
ization of open, vendor‐neutral, cross‐platform color management systems. One of the unique features of ColorPro is that you can mix and match SetGoldPro profiles and ICC compliant profiles within ColorPro setups, if that is what produces the best results for you.
ColorPro solves real‐world color reproduction problems for the graphic arts market and is available as a password protected option in the Harlequin MultiRIP. Global Graphics Software (GGS) supplies a range of device profiles for commonly used color standards. These profiles are available for immediate use and incorporate linearization data for out‐
put devices.
Some graphics applications include color management information in images or jobs that they pro‐
duce; Adobe Photoshop is one such application. When processing jobs from these applications, you can choose to use either the color management information contained in the jobs or the more detailed controls provided by a ColorPro option. Jobs can contain color management information in several forms: as an embedded ICC profile; a color space array (CSA); or as specified by UseCIEColor. See Appendix C, “Jobs Containing Color Management Data”, for details.

1.3 Harlequin ColorPro features
Harlequin ColorPro is a complete and accurate color reproduction solution. It is a device‐indepen‐
dent, cross‐platform color management system developed to control color in today’s digital printing and publishing environments. ColorPro manages all aspects of color print reproduction and is fully compatible with accepted industry standards.
ColorPro offers a technology‐independent solution. Unlike most systems, which force you to compen‐
sate for color before you know how a job will be printed, ColorPro works without regard to the input and output devices used. In other words, you do not need to specify which devices will be used at the time the PostScript job is created. At run‐time, ColorPro applies the proper transformations.
ColorPro allows you to specify different gamut‐mapping algorithms in the reproduction of a page. For example, you can simultaneously specify Absolute colorimetric to reproduce some elements of the page and yet specify Perceptual to reproduce the photographs. The end result is that, on a single page, the color for photographs is calculated without affecting other elements on the page.
Harlequin ColorPro allows processing of colors in page data using SetGoldPro profiles or ICC profiles produced by OEMs, third parties, or end‐users using third party characterization and profiling tools. Profiles specify a translation between two color spaces. Each profile is prepared for a specific set of imaging conditions. One device may have more than one profile. The profiles may correspond to run‐
ning the device with different combinations of resolutions, inks, and paper.
New profiles can be easily added to ColorPro, and previously installed profiles can be selected with‐
out the need to reinstall each time a profile is used. An option to install and uninstall ICC profiles is provided.
In addition, ColorPro allows the use of profiles prepared in the Harlequin MultiRIP format. Global Graphics supplies a number of profiles for commonly used systems. See Appendix E, “Supplied Profiles”, for details.
1.4 What’s new in Harlequin ColorPro?
The following have changes have been made to ColorPro:
•
The Use late color management option is changed to Overprint preview.
•
The Image only black option is deprecated and should not be used.
1.5 Color and calibration
To ensure high color accuracy, make sure you calibrate your output device. See the chapter on “Cali‐
bration” in the Harlequin MultiRIP OEM Manual.
1.6 Color mapping styles used in ColorPro
Various color mapping strategies are available with ColorPro. The standard strategies are:
•
Default Absolute Colorimetric
•
Default Relative Colorimetric
•
Default Perceptual
•
Default Saturation


These rendering intents use the values from an installed ICC profile together with settings from the Color Setup dialog box to generate a CRD at run time.
The information in this section also applies to the rendering intents that appear when ICC profiles are selected and when using the ->Default option. For example:
•
‐>ICC colorimetric
•
‐>ICC perceptual
•
‐>ICC saturation
The ->ICC rendering intents use CRD’s installed in the RIP, and appear when an ICC profile has been installed and selected as either an Output Profile, (when emulation is not selected), or as an Emulation
Profile.
Harlequin ColorPro can use these strategies from both ICC and Harlequin profiles. You are also able to modify these strategies and save them as new, named, strategies for later use.
The difference between the Harlequin derived and ICC rendering intents is that you are able to cus‐
tomize the Harlequin rendering intents using the Rendering Intent Manager see “Custom rendering intents” on page 26 for more information.
The names, Absolute colorimetric, Relative colorimetric, Perceptual and Saturation are the conven‐
tional terms for these color mapping strategies (rendering intents), and the Harlequin MultiRIP uses these names for rendering intents derived from Harlequin profiles. The names that appear for rendering intents derived from ICC profiles are slightly different—there is only one colorimetric intent—but all the same styles are available to the Harlequin MultiRIP, provided that an ICC profile contains them. ICC and Harlequin rendering intents are not same but they do pro‐
duce similar results.
The different naming scheme makes it easier for the best rendering intent to be selected by ColorPro so that it best suits the other choices you have made when creating a color setup.
Section 1.6.1 through Section 1.6.4 fully describe these options.
Appendix G, “Printing Color”, has further details on absolute colorimetric mapping and perceptual mapping. 1.6.1 Absolute colorimetric
Any color the device can reproduce (with the intended setup and viewing conditions) is reproduced exactly. Colors outside the device gamut are mapped onto a “nearby” point in the gamut. There are various ways in which a color might be out of gamut. For example, it could be too saturated, lighter than the paper color, or darker than the darkest imageable patch.
Colorimetric reproduction is appropriate where an exact color match is required. For example, you may choose a colorimetric strategy when you are reproducing a logo in corporate colors.
Note: Absolute and relative colorimetric styles are closely related. For simplicity, ColorPro displays just the single name ICC colorimetric but internally it is able to use either style where it is appropriate.
1.6.2 Relative colorimetric
This style aims to reproduce colors exactly, except that the luminance (how light or dark a color is) is scaled so that the darkest possible color is mapped to the darkest imageable color, and the lightest possible color to the paper white. This style may change the hue (degree of redness, blueness, and so on) of any color, and is almost certain to affect the luminance of most colors.


Some scanners and applications produce data that has been adjusted so that the lightest and darkest point are encoded as maximum and minimum lightness. For interpreting this kind of image, the rela‐
tive colorimetric style is appropriate.
1.6.3 Perceptual
This style maps the entire device‐independent color space onto the gamut of the printer by compress‐
ing the range of in‐gamut colors to make room for out‐of‐gamut colors. It is appropriate for rendering photographs and similar reproductions of natural scenes.
Note: This strategy was named Photorealistic in early Harlequin MultiRIP color management systems.
1.6.4 Saturation
This style specifies that the saturation of the colors in the image is preserved, perhaps at the expense of accuracy in hue and lightness.
Note: This strategy was named Business Graphics in early Harlequin MultiRIP color management sys‐
tems.
1.6.5 Paper simulation
ColorPro allows you to reproduce the paper color of the input job in the output from the Harlequin MultiRIP. This option is an important feature because, for example, some proofing stocks are very blue and contain optical brighteners which are not typical of papers that are run through presses (at least presses running inks). Thus paper simulation can help in proofing.
Paper simulation is controlled by the Simulate paper color of job check box in the Input Document
Controls section of the New Color Setup dialog box. ColorPro processes other colors on the page to match the chosen background, so this setting implies “absolute” and “relative” modes. This could be a problem if the chosen rendering intent made a conflicting choice of absolute or relative rendering.
If the Simulate paper color of job check box is selected when using the ->ICC colorimetric intent option, the color is absolute. When the check box is not selected the color is relative. This means that there cannot be a conflict, but allows full access to the rendering intents.
To clarify, if the Simulate paper color of job check box is selected when using the ICC colorimetric intent option, it changes the ->ICC colorimetric option to absolute and the background color of the paper would appear on the proof. That is, if the background color of the paper is yellow, the proof would appear more yellow.
If the Simulate paper color of job check box is not checked, the ->ICC colorimetric option becomes relative and the background color of the paper would not appear on the proof.
If the selected ICC intent is perceptual, saturation or one of the Harlequin derived intents, the RIP attempts to simulate the background.
Note: It is possible for a conflict to arise for the Harlequin derived rendering intents, because the Simulate paper color of job option only sorts things out for ICC rendering intents.
1.6.6 Rendering intent selection for emulation
In the ColorPro dialog there is no option for selecting a proofer rendering intent when an emulation profile is selected. When a profile is selected from the Output Emulation menu, the rendering intents selected in the Output Rendering Intents section apply to this profile. (It is not possible to select a ren‐
dering intent for the profile selected in the Output profile option.)
INDEX


The Harlequin MultiRIP automatically selects a rendering intent for the output profile in the follow‐
ing way:
1.
If the Output Profile has any ICC output profiles associated with it, the RIP uses a Colorimetric profile if one exists.
2.
If there is not a colorimetric profile, the RIP attempts to use a Relative colorimetric profile.
3.
If a Relative colorimetric profile does not exist, the RIP uses the first profile it finds in the list of output profiles associated with the ICC profile.
4.
If the Output profile has no associated ICC output profiles, the RIP generates a CRD with the CRD generator plugin. In this case the rendering intent used is Absolute colorimetric.
For information on how to choose these options see Table 3.8, page 37.
1.6.7 ICC auto-switching
Generally, rendering intents are manually assigned using the various options available within Color‐
Pro. However, if you select an ICC output profile, ICC auto‐switching becomes an available option in the Output Rendering Intents.
ICC auto‐switching intelligently assigns different rendering intents based on the image types within a file. •
CMYK images are set to ICC colorimetric.
•
RGB images are set to ICC perceptual.

Chapter 2–ColorPro workflows
2.1 Introduction
This section describes some useful workflows and how to configure them using the Harlequin MultiRIP and ColorPro. These workflows are intended as examples to demonstrate practical solutions to common workflow configurations. The workflows are shown first with the most straightforward and becoming increasingly more complex. It is hoped that you find a workflow that closely matches your system requirements and, with a few minor adjustments, quickly get your system up and run‐
ning.
There are several dialog boxes shown in this section with various options selected. Explanations are given where useful but full descriptions of every option are not given. For full descriptions of all the available options in the dialogs, see “Using ColorPro” on page 18.
In this section the following workflows are described:
•
CMYK analog matching, see “CMYK—analog matching” on page 9.
•
CMYK press proofing, see “CMYK—press proofing” on page 10.
•
RGB Profiling—ICC model, see “RGB Proofing—ICC model” on page 12.
•
RGB Proofing—SetGoldPro and Harlequin Pro models, see “RGB Proofing—SetGoldPro and Harlequin ColorPro models” on page 14.
•
Multiple color space proofing, see “Multiple color space proofing” on page 15.
•
For a discussion on emulation workflows, see “Emulation workflow details” on page 17.
2.2 CMYK—analog matching
It is often required that your proofs are matched against an analog proofing system. In this scenario you would need ColorPro activated to create a custom color setup.
Harlequin ColorPro is supplied with a representative group of input profiles, pre‐configured and ready for use, which are based on many of the traditional analog proofing systems.

Because of this extra functionality you must also make additional selections from within ColorPro to obtain the intended results. An example is shown below:
Figure 2.1 CMYK analog matching
This setup shows an input profile based on DuPont Cromalin with selection of a device using glossy photo paper.
When you create your Color Setup, remember to select the device for which you have a plugin from the Device menu in the Color Manager. See “Define color setups using ColorPro” on page 29 for more information.
2.3 CMYK—press proofing
In a CMYK workflow it is sometimes useful to make a press proof based on a standard such as SWOP or Fogra. Again, Harlequin ColorPro provides some standard profiles to make this possible. How‐
ever, if you have access to an ICC profile that describes the actual behavior of the press on which the job is going to run (typically provided by a print shop), that profile should be installed into the RIP before creating a ColorPro setup. In this way the color transforms are able to achieve the most color INDEX

accurate proof for your job. For more information on installing ICC profiles, see “Install ICC profiles” on page 20.

2.4 RGB Proofing—ICC model
If a customer has several editorial pages from a magazine that need to be proofed to SWOP, a maga‐
zine industry standard, a single transform will not produce a color accurate proof. This is because when you send an RGB image to the RIP and select a proofing device, the proof contains the images transformed only from the RGB color space to the color space of the proofing device. The proof will appear very colorful and pleasing to look at, due to the large color gamut of the inkjet device, how‐
ever, in no way will this print be representative of what the images will look like on a printing press. Therefore, before proofing RGB images an understanding of profiles and rendering intents is required to achieve the desired results.
In the first instance, the profiles must be installed correctly and then the rendering intents should be selected. Considering an ICC workflow first. Depending on where the RGB images are coming from you may want to install an RGB profile in the RIP to control the color transforms for all RGB images. The installation of the RGB input profile is shown below:

The new ColorPro emulation feature allows you to accurately proof RGB images. By selecting Perceptual Rendering for the first transform from RGB to SWOP, you are assured that the image is rendered to the full gamut of the press while the second transform, from SWOP to the device profile, provides the color accurate proof. Currently, the second color transform is Absolute Colorimetric.

2.5 RGB Proofing—SetGoldPro and Harlequin ColorPro models
The discussion on RGB proofing using the ICC model applies here. However, in this application you use the ColorPro technology within the RIP to build the color transforms as needed. This requires some additional work to build the input, emulation and output profiles using SetGoldPro, whereas in the ICC model the profiles were built using a third party application. The goal of both approaches is to obtain color accurate proofs. One approach uses third party applications to build the necessary pro‐
files (ICC) and one uses the Global Graphics’ Color utility SetGoldPro to build the profiles.
For more information on SetGoldPro, see the documentation accompanying that product.
In this model, the color accuracy is determined by the color science in the Harlequin MultiRIP because the CRDs are generated “on the fly” as needed within the RIP and then saved for future use. A unique feature of ColorPro is that it allows you to use some ICC profiles and some Harlequin profiles, if that is your preferred solution.
One possible scenario is that you could use SetGoldPro to make an optimized output profile for a given device, ink and paper combination but use a press profile in an ICC format supplied by your INDEX

print shop. In this ColorPro setup, you use the ICC profile supplied by your print shop in the emula‐
tion slot and the Harlequin profile for the output.
Figure 2.9 Use the emulation ICC profile supplied by print shop
2.6 Multiple color space proofing
Magazine publishers may receive editorial images from digital cameras which are RGB images, and ads from their vendors as CMYK images. The problem is that both editorial (RGB) and ad images (CMYK) can appear on the same page and the publisher will want to create digital proofs which are representative of what the page is going to look like on press.
With ColorPro, assuming the correct profiles and rendering intents have been selected, this type of proofing is possible. Thus a mixed color space page layout requirement can still be proofed accurately for color, allowing for the editorial group to stay in the RGB world and the ad agencies in CMYK.
Two sample setups are shown below. This first setup uses SetGoldPro generated profiles with the exception of the RGB profile, which is an ICC profile in this example. Note that there are individual input profiles and rendering intents for INDEX

both CMYK and RGB images. (Other CMYK objects will use the Main intent.) The output emulation could be one supplied by your print shop and the output profile is for an inkjet printer.

2.7 Emulation workflow details
When an ICC profile is installed as an emulation profile, the RIP also installs it as an input profile, because the RIP needs to use it later in the color chain.
The chain is:
Input Profile
Emulation
that job was
designed for
device
profile
Emulation
input profile
Output
Profile
for proofer
Figure 2.12 Full color chain
You only select the emulation profile once in the ColorPro setup, but it is used twice. The CRDs are used first, and then the color space is used to effectively start the second stage of the color chain.
It could be that the profile that the job was designed for is the same as the device profile that you want to emulate. That is, the job will ultimately be printed on the press that it was designed for. However, you may want to proof it on another device first. In this case, it is reasonable to select the same input profile as the emulation profile, for example, for the CMYK input. This would still give a better route for RGB than just using an RGB input profile and the output profile of the proofer, because that does not take any account of the press it is ultimately going to be printed on.
In the case of the CMYK data, this would give a very similar result to just going from the input profile the job was designed for to the proofer profile.
The point is, selecting the same input profile as emulation profile, is mainly useful for RGB or mixed RGB/CMYK inputs. For pure CMYK inputs, you may not gain any improvement over using the color chain:
Input Profile
that job was
designed for
Output
Profile
for proofer
Figure 2.13 CMYK color chain
In a case where the emulation profile is not the same as the profile the job was designed for, you should expect the full (4 stage) color chain to give some benefits in that it takes account of all three profiles involved, namely, the one the job was designed for, the one it is ultimately intended to be printed on, and the proofer profile. The amount of improvement over using the color chain shown in Figure 2.13 depends on the exact profiles involved.

Chapter 3–Using ColorPro
Harlequin ColorPro offers fully customizable color management capabilities based on the device, image components, and the color reproduction process used. When you enable Harlequin ColorPro you can use SetGoldPro profiles, ICC profiles and supplied profiles delivered with each device plugin or a combination of these if needed.
Figure 3.14 shows the whole process from installing a profile through defining custom color render‐
ing intents to printing a job.
Note: SetGold profiles cannot be imported into ColorPro because they are not ICC profiles.
ICC profiles may be produced by OEMs or by end users with third party characterization and profil‐
ing tools. Once you have installed the ICC profiles in your system, you can use any combination of them to create customized setups. The Harlequin MultiRIP can also use an ICC profile embedded in an image. In addition, Harlequin ColorPro provides features that allow control over parameters used in creating color setups. These unique features include:
•
Customizable color rendering intents. You can control exactly the way you want to reproduce different objects on a page by defining custom rendering intents and specifying which types of objects the intents should affect. For example, on the same page, you can simultaneously repro‐
duce images using a perceptual rendering intent (photorealistically) and the other elements of the page using absolute colorimetry. See “Custom rendering intents” on page 26 for more infor‐
mation.
•
Color reproduction that is adjustable based on viewing conditions. Viewing conditions available include Graphic Arts D50, Monitor D65, Daylight, and Home and Office. See Table 3.10 for more information.
•
Calibrated and configurable reproduction of named PANTONE colors from the PANTONE MATCHING SYSTEM.
•
Manual override capability.

3.1 Get ready to use Harlequin ColorPro
Before creating color setups using ColorPro, you must set up access to the application: •
If you are using Sentinel LDK security you will need a new product key. For more information see the Sentinel LDK security document.
•
If you are using the Harlequin License Server (HLS) you must have a password that enables Harlequin ColorPro. See below.
The Harlequin MultiRIP can read the password from a file if the installation process for a plugin or other option supplied one. If the Harlequin MultiRIP reads a password file, which it does when next starting up, it displays a dialog box with a message like this:
Imported password file Passwords/1234-56-7654321.pwd
This message only appears the first time the RIP is started.
Click OK to dismiss this dialog box. You can still use the manual procedures as described below as a way of enabling or checking options.

3.2 Enabling ColorPro
If you are using Sentinel LDK security you should order a new product key to enable ColorPro. For details on how to perform an upgrade see the Sentinel LDK security document.
If you are using the Harlequin License Server (HLS) you will have been provided with a ColorPro password. Use the following procedure o enable ColorPro when using HLS: 1.
Start the RIP and select Harlequin RIP > Configure RIP, to open the Configure RIP dialog. 2.
Click the Extras button to open the Configure RIP Extras window. 3.
From the list of RIP extras, select ColorPro and click Add. 4.
In the Enable Feature dialog that appears enter your ColorPro password and click OK. 5.
Click OK to close the Configure RIP Extras dialog, and OK to close the Configure RIP dialog.
You can now begin to setup the features available with ColorPro. If you have access to device profiles and various output devices, you can start using ColorPro.
For more information on HLS see the Harlequin License Server document.
3.3 ColorPro overview
ColorPro is designed so that you can quickly create a color setup that suits your needs. There are sev‐
eral steps to creating a setup; some you may or may not need. The various stages are shown below:
•
Install any ICC profiles you may need. See “Install ICC profiles” on page 20. If you do not have any ICC profiles to install, this step can be skipped.
•
Define any color or custom rendering intents you wish to use. See “Define color rendering intents” on page 25. If you intend to use the default rendering intents you can skip this section.
•
Configure your ColorPro setup. See “Define color setups using ColorPro” on page 29. The ColorPro setup dialog is divided into several areas. The left side of the dialog handles the input and the right side handles the output. For help in deciding how to configure you workflow, see Chapter 2, “ColorPro workflows” for more information.
3.4 Install ICC profiles
Before you create color setups, you may install any ICC profiles that you expect to use. Identify the types of profiles you need and then install them.
3.4.1 Types of profiles
ICC profiles vary in how much information they contain. From a suitable ICC profile, you can install an input profile, a device (or output) profile, an emulation profile, or all three. The profile installation dialog box shows you the options and you must explicitly choose how you want to install an ICC pro‐
file (as an input profile, output profile, and so on), in order to use the profile to define a color setup. For example, if you want to use the same ICC profile as an emulating profile in one color setup and as a device profile in another color setup, you must install the ICC profile as both an emulating profile and a device profile, by selecting both check boxes. You can, at any time, make additions to how you want to use an ICC profile. If you want to use an ICC profile (that is currently defined as an input pro‐
file only), as a device profile in a color setup, you can reinstall the ICC profile as a device profile.
Note: When a profile is installed as an emulation profile, it is automatically installed as an input pro‐
file for the appropriate color space.

 21

You can get started using one input profile. However, Harlequin ColorPro can use various types of profiles. GGS supplies some commonly used profiles. For more information see Appendix E, “Supplied Profiles”.
Input profiles for CMYK and RGB are pre‐installed. If you do not have suitable profiles for your sys‐
tem, you must make available at least one from each of these types: •
Input CMYK profile. Install at least one ICC profile as a CMYK input profile or a device link pro‐
file. An input profile colorimetrically transforms color data from a device‐dependent color space to a device‐independent color space, where ColorPro options can process the data and supply it to an output profile, which you can choose separately to suit your output device. A device link profile maps colors between two device‐dependent color spaces. In this case, the color data bypasses ColorPro color management to pass with a predefined transformation directly between the input device and the output device.
•
Input RGB profile. Install at least one ICC profile as an RGB input profile or a device link profile. The RGB input profile translates the input to a device‐independent color space so that the result‐
ing colors match the colors that can be produced on a monitor. The device link RGB profile bypasses ColorPro color management to map the RGB colors directly to the output device.
Note: Most ICC profiles are suitable for installation as either input or output profiles. The same profile, however, cannot be used as both a CMYK and an RGB input profile. Before you create any color setups in ColorPro make sure you have available at least one CMYK and one RGB input profile.
•
Device (or output) profile. Install at least one ICC profile as a device (or output) profile. This pro‐
file must be an ICC output profile that is appropriate for the printer to be used. This profile does the opposite of what an input profile does. Based on information about the output device and imaging conditions, the output profile transforms the device‐independent color space back into a device‐dependent color space.
Note: Before you import an ICC profile into the Harlequin MultiRIP, you should make sure that you have set up the profile correctly for the given device type in the ICC profiling package. Understand‐
ing the correct use of ICC profiles for a given device type is essential to successful color proofing.
Note: You are not able to install an ICC profile which is created for a device that has a different num‐
ber of colorants to your device. For example, a six color ICC profile cannot be installed if you device only supports four colors. In addition, the colorant names must match. That is, at least one of the alter‐
native colorant names for each device colorant must match one of the colorant names in the profile.
3.4.1.1 Calibration and output profiles
It is possible to construct color profiles starting from the different states of the output device being profiled. Two of the most common starting states are:
•
The uncalibrated or “raw” state of the device.
•
The device after adjustment of the individual channels for linearity, and usually with some bal‐
ancing of the channels to produce a gray‐balanced or neutral state; this is known as the “refer‐
ence” or “golden” state. In fact, there are as many reference states as there are combinations of device, resolution, media and ink. Note to OEM:
In the production of device color characterization profiles we have found that it is good practice to make profiles relative to the reference state. We supply Harlequin MultiRIP plugins with profiles for several combinations of resolution, media and ink. When you install an ICC profile as a device profile, it is important to know what calibration profile was used to print the color characterization target used in the output profile making process.

import to the RIP of the ICC profile, this calibration (SetGold profile) profile must be the same as described above and selected in the Linear Calibration From option pull down menu to make the link between the Golden State of the device, contained in the SetGold profile, and the devices ICC color profile.
3.4.2 Install ICC profiles
When you have configured access to Harlequin ColorPro, you can begin installing ICC profiles. 1.

Device Link Profile Select this option to install the ICC profile as a device link profile. Note: A device link profile maps colors between two device‐dependent color spaces. In this case, the device link profile bypasses colorimetry to map colors directly between the input device and the output device.
An emulation profile is a profile that enables an output device, such as a proofing printer, to reproduce the color characteristics of another device, such as a print‐
ing press. Because a typical proofing device has a larger gamut than a printing press, the emulation profile limits the color gamut on the proofer device to that of the device the emulation profile is for. Emulation Select this option to install the ICC profile as an emula‐
tion profile. This option is disabled if the profile being installed is a device link profile.
Note: When you install a profile as an emulation profile, it is automatically installed as an input profile for the appropriate color space.
Device Profile Select this option to install the ICC profile as a device (or output) profile. If you select this option, you must also choose a device from the For Device menu. Once installed with this option, the profile becomes available as an output profile in the New Color Setup dialog box.
For Device If you selected the Device Profile option, choose the out‐
put device for the device profile. If you wish to use the same profile for more than one device, you must install it for each device.
When creating CMYK Separations you should select Printing Press.
Color space
This is the color space of the profile. Generally profiles are provided for a single color space. However, some profiles are supplied for more than one color space. In this case you should select the color space which you would like to use.

You may need to alter the second bullet point in the description of Linear

files shown in the Linear Calibration From menu indicates the device, media and resolution. If you supply additional ICC profiles, one simple option is to create each ICC profile by printing an ICC target using the appropriate Harlequin profile and following a similar naming policy for the resulting ICC profile. To resume the process, follow these steps:

Note: Input profiles are not device specific so appear whatever the Device selector is set to.
The related profiles appear in the main Profile window. 3.
The Uninstall for uses check boxes allow uninstallation for All uses of the selected profiles, or just some. The check boxes are only enabled when there are profiles selected. If All is selected, the five individual use check‐boxes are all disabled, otherwise they are enabled if at least one of the selected profiles is installed for that use. For example, if none of the selected profiles were installed for emulation, the Emulation check box is disabled.

Click on the Uninstall button to uninstall the selected profiles. The Uninstall button is only enabled when there are profiles selected. 5.
To close the dialog click the Done button. The dialog is not automatically closed after clicking Uninstall.
Note: You are unable to uninstall ICC profiles that are being used by color setups. If an attempt is made to uninstall such a profile a message is displayed:
Unable to uninstall the profile ‘<profile name>’ because it is used by the color
setup ‘<color setup name>’
For example;
Unable to uninstall the profile ‘Bvd-fogr’because it is used by the color setup ‘bvd’
Note: If the same profile is used by several setups, the error message shows only one setup at a time, and not all the setups the profile is used for.
To identify a profile which you have created, you should add, (for example), "%%Creator: <OEM
name>".
3.5 Define color rendering intents
If you are building a color setup for a new device, custom rendering intents are useful for optimizing the color and quality of the proof based on the ink, paper, resolution and screening combination. Cus‐

tom rendering intents are used to optimize the CRDs when making color setups for a new device. They are then used a second time to globally adjust the color to satisfy customer requirements.
When ColorPro is enabled you can define custom color rendering intents, but this is not essential at first use of Harlequin ColorPro because you can get good results using the default rendering intents.
ColorPro is supplied with default rendering intents that you can use immediately. Each default ren‐
dering intent has a name that closely matches the style on which it is based, and the styles correspond to, but are independent of, the names of intents supplied in ICC profiles. For example, the Default Perceptual rendering intent uses the Perceptual style.
If you want to use only default rendering intents or rendering intents derived from ICC profiles, see “Install ICC profiles” on page 20 or “Define color setups using ColorPro” on page 29. You can return to the remainder of this section if you want to go ahead and create a custom rendering intent.
Note: The ->Default rendering intent cannot be edited using the Rendering Intent Manager. This is because it is already a CRD created with specific settings.
3.5.1 Custom rendering intents
You define a custom color rendering intent by specifying combinations of settings to be used with a style. Some settings allow you to achieve the intention of the style in a way that best suits the technology of a particular output device without having a significant visual effect. For example, you can alter the black generation strategy. Other settings allow you to modify the visual appearance of the result, but move away from being strictly colorimetric.
Custom rendering intents are used in combination with SetGoldPro output profiles when building profiles for a new device and to adjust color to meet customer requirements.
Follow these steps to create customized intents.
1.
Choose Color > Color Rendering Intent Manager. The Color Rendering Intent Manager dialog box appears.

Appendix E.2, “RGB Input Profiles” describes all supplied RGB input profiles.
Color manage gray as
CMYK
By selecting this option, monochrome (gray) data uses the input profile selected in the CMYK data field and is color managed as CMYK. When this option is selected the Gray data menu becomes unavailable.
If this option is unchecked, the selection in the Gray data field is used.
Gray data
From the menu, select either None or any gray profile you have installed. Incoming gray data uses the selected profile unless you choose None, in which case gray data does not have any color management. Gray ICC profiles can be created from Photoshop v6.5, exported and then installed into the RIP.
Treat spot colors as
CMYK
When an input profile has been selected in the CMYK data field, this option becomes available. Checking this option makes any spot color in the job use the input profile speci‐
fied in the CMYK data field.
When this checkbox is disabled, spot colors will always be treated as CMYK.
If this option is not selected, the Pantone color is chosen using the XYZ Pantone lookup table (within the RIP), which in turn gives the proof a best match for the Pantone color but is not indicative of what the color will look like on press.

Note: A PDF/X‐3 file containing an OutputIntents diction‐
ary will normally be color managed using the OutputInt‐
ents profile. If instead, it is desired to color manage using some other profile, it is necessary to set the Override color

Override overprint
mode in job
There is a new PostScript operator called setoverprintmode which is the PostScript equivalent of the PDF gstate OPM flag.
If an object is set to overprint and OPM or setoverprintmode is on, the Harlequin MultiRIP drops any colorants which have a zero value. This is called “implicit overprinting”.
This is what the Override overprint mode in job option con‐
trols.
If the Override overprint mode in job option is selected, the Overprint process colors option (described below) is always honored and any overprintmode and OPM parameter in the job is ignored. If it is not selected, any overprintmode and OPM parameter in the job is used and the Overprint process
colors setting is used as the default value.
For more information see Appendix D, “Overprinting options”.
Overprint process
colors
If this option is selected and overprinting is switched on for an object, the RIP overprints any process color component defined as 0 in the CMYK color space, or as 1 in the RGB color space. That is, the component is treated as transparent.
When this option is not selected, a process color compo‐
nent produces a knockout on the separation. However, if overprinting is switched on for an object, the RIP over‐
prints colorants that are explicitly set to overprint using the Harlequin extension setcmykcolor. For more information see Appendix D, “Overprinting options”.

When Overprint process colors is selected, Drop white objects
determines how the RIP handles white objects: objects defined as 0 0 0 0 setcmykcolor, 1 setgray, or 1 1 1 setrgbcolor.
If this option is selected and overprinting is switched on for that object, the white object simply disappears from the separations.
If this option is not selected, the white object knocks out underlying objects, even when overprinting is switched on.
By default, this option is not selected.
For more information see Appendix D, “Overprinting options”.

Description
Overprint grays
Select this option to enable the cyan, magenta, and yellow colorants to be overprinted rather than knocked out when a color is specified as gray (with the PostScript language setgray operator or spot color converted to a gray level), and the job requests overprinting. This behavior is not defined by the PostScript language, and though it is unusual for a job to rely on it, sometimes a job assumes this, especially when the gray tint arises from a named black spot color which is converted to process.

For more information see Appendix D, “Overprinting options”.
Overprint gray images
Overprint behavior changed from Harlequin RIP version 4.1 to 5.x and beyond. While the old behavior is deemed incorrect, there is a desire to selectively use the old behav‐
ior because of the un‐predictability of some graphic appli‐
cations and to provide for end‐users the ability to handle legacy work.
The user parameter is called OverprintGrayImages, with a default of true which when set overprints gray images. If it is set to false, gray images will knock out of CMY back‐
grounds.
Overprint 100% black
When this option is selected, the RIP overprints 100% black rather then generating knockouts in the other separations. The black channel or separation is generated as normal but, depending upon the characteristics of the other inks, may need to be applied last in the combination process so that it overprints all colors necessary. If this option is selected, overprinting occurs regardless of whether overprinting is switched on for that graphics object.
There is no performance penalty incurred by using this fea‐
ture—in fact, it may be slightly faster to overprint, given that knockouts do not have to be calculated. This feature only applies to black objects, not to individual pixels of a continuous tone image that happen to be 100% black.
Image only black
This option is deprecated and should not be used.
Overprint preview
Applying Overprint preview gives better quality results with blended colors.
See below for more information.
Table 3.4 Input Document Controls (Continued)
Notes on Overprint preview
The Overprint preview option overcomes problems with color managing blended colors. In this con‐
text, blended colors means both the compositing of transparency in PDF jobs, and also the overprint‐
ing of opaque objects in PostScript language and PDF files.
In order to color manage blending correctly, the blending must be performed in the same color space that the designer worked in when creating the job. For example, SWOP with a range of Pantone col‐
INDEX
CONTENTS
 35

ors. In theory, if this type of job is printed on a SWOP press that supports all the Pantone colors pres‐
ent in the job, the rendering of the blends will be correct.
Problems arise when the job is printed to a device with different characteristics to the color space the designer worked in. A typical usage is the need to color manage the job when printing to a proofing device. In this case, to reproduce the blending the designer intended, the blending should be per‐
formed in SWOP with the result then color managed to the proofing device. Historically, this has been difficult to do accurately without using a form of “double pass” RIP processing. That is, the job is RIP processed once to (for example) TIFF, in which the blending is in SWOP. The second RIP pass then color converts the TIFF and outputs the result to the proofing device.
When the Overprint preview option is off, the Harlequin MultiRIP will perform color management of colors in the job before overprints. The RIP performs blending by using the available information to make a “best guess” at the blended colors, but at a late stage in the RIP process and without full knowledge of the color values and other graphics state attributes. This method usually makes the blended regions visible, although they are not correctly color managed. And if spot colorants are con‐
verted to process colors, overprinting of these objects is disabled by default.
When the Overprint preview option is selected, color managed blending is performed in a single pass of RIP processing with its obvious efficiency benefits. The Overprint preview option is available on both ColorPro and No color management color setups. The option is available in No color management setups to achieve better rendering of overprinted spot colors. For accurate proofing of jobs containing transparency and/or overprints, it is recommended that the Overprint preview option is used.
Please note the following points when using Overprint preview:
•
The definitions of tint transforms of spot colors in the job (which are used to derive the CMYK equivalents) will only be used to derive the CMYK equivalent of the 100% color value. Tints will be rendered with CMYK values derived from the 100% spot. Note: If the Treat spot colors as CMYK option in a ColorPro setup is off (the default), the RIP attempts to find the equivalent from the spot color databases in preference to using the tint trans‐
form. That is long‐standing ColorPro behavior. See Table 3.3 for more information.
•
If a job contains multiple color spaces of the same spot color, and where there are multiple defi‐
nitions of the tint transform, only the first tint transform encountered will be used; as above.
•
Overprint preview is forced on when used with recombine.
•
Overprint preview may affect performance either positively or negatively since it is difficult to predict how individual jobs will be affected.

The following table describes the Output Emulation option of the New Color Setup dialog box Fields
Description
Output Emulation
Emulation is used when you proof on a different device to that used for final output, because a typical proofing device has a larger color gamut than a printing press. Using an emulation profile, the proofer limits the range of colors so that it prints to the gamut of the device being emulated.
For example, if you are proofing on an inkjet printer, you can use a profile of your printing press to emulate, on the proofer, the characteristics of the press.
If you specify an emulation profile, the chosen rendering intents are applied to the emulation profile, and not the proofer profile.
When you have selected an emulation profile, you can click the Info button to display the characteristics of the profile. Verify that you have chosen the appropriate profile.

Main intent
You should select a rendering intent from the menu. This is the rendering intent which is used for all objects, unless you have specifically chosen a rendering intent for CMYK or RGB images (described below).
The list depends on the choice of emulation profile, but does not include it.
The ICC rendering intents are those appropriate to the out‐
put profile selected, (or if you have selected an emulation profile, they are appropriate to the emulation profile selected). The list includes (None), the default intents and any cus‐
tom intents you created (as described in “Define color rendering intents” on page 25), and usually:
(->ICC perceptual),
(->ICC saturation),
(->ICC colorimetric).
You can select the button to the right of the option to dis‐
play the Color Rendering Intent Manager from which you can create new rendering intents, see “Define color rendering intents” on page 25 for more information.
See “Color mapping styles used in ColorPro” on page 5 for detailed descriptions of all intents (styles).
Main intent (cont)
If you select an ICC output profile, ICC auto-switching becomes an available option. ICC auto‐switching intelli‐
gently assigns different rendering intents based on the image types within a file. CMYK images are set to ICC colorimetric.
RGB images are set to ICC perceptual.
CMYK Images
This option overrides any selection you made in the Main intent field but for images only. It applies to all images including Gray and RGB images. If required however, you can select an option specifically for RGB images from the RGB Images intent menu (below) which overrides this intent with its own option (described below).

Use black point
compensation
From v8.0r0 Black point compensation has been added to ColorPro and is compatible with the Adobe implementation.
Black point compensation is used when converting images from the color space of one device to the color space of another device. It accounts for the differences in the dark‐
est level of black which can be printed on those devices.
The implementation in the RIP will only work with color transforms composed entirely of ICC profiles, that is, the method will have no effect on device independent color spaces such as CalGray, CalRGB, CIEBasedxxx, but will work for ICCBased and embedded ICC profiles. Also, the ICC profiles supplied in setreproduction must be installed in a v8.0r0 RIP, that is, the method will have no effect on output profiles migrated from earlier versions of the RIP.

Lighting
ColorPro provides compensation control over the local viewing conditions which include Graphic Arts D50, Monitor D65, Daylight, Home and Office.
Much graphic arts work uses D50 illumination throughout the process to minimize transforms when converting data through the color chain. Thus, targets are measured with D50, colors are transformed from input to output through the ICC (profile connection space), PCS in D50, and the proofs are viewed under D50 illumination. However, some systems have alternative methods which include D65 view‐
ing boxes and sometimes no lighting system for viewing prints at all. The lighting options are provided to help someone who knows that the proofs are going to be viewed in a non‐tra‐
ditional D50 lighting situation and has some idea how they are going to be viewed.

Color adjustments
From v8.0r0 the Faster and Accurate image color adjust‐
ment methods have been replaced to use a different algo‐
rithm that is much more predictable than the previous versions. The Faster algorithm no longer uses the error scattering method which avoids problems with the com‐
pressibility of the final output.
 40

The Faster algorithm will improve performance of 3+ com‐
ponent images, but will particularly improve CMYK images. All three options use the same interpolation algo‐
rithm, the only difference is the number of grid points per colorant. There is always a difference between the three methods, with Accurate being the most accurate and slower, while Faster is always faster and less accurate. The Better option sits somewhere between Accurate and Faster with regard to quality and speed.
However, Faster may well be accurate enough for most purposes. The only method of finding out which is most suitable for a particular purpose is to experiment.

If this is the first time you are using newly defined color rendering intents to print a job, the Harlequin MultiRIP requires a few extra minutes to produce the output. This is because the Harlequin MultiRIP must generate the color rendering dictionaries before printing. If you submit another print job that uses the same intents, the Harlequin MultiRIP does not regenerate these dictionaries and printing proceeds more quickly.

Appendix A – UCR and Black Generation
It is always desirable to use the full capabilities of an output device. This often means processing a supplied 3‐color definition so that it uses all colors of a 4‐color output device. There are various tech‐
niques for achieving this. Undercolor removal (UCR), gray component replacement (GCR), and black generation are some of these techniques.
Whether ColorPro color management is in use or not, you can see controls that apply these techniques in the Output Controls for RGB section of the Color Setup dialog box. This appendix describes the cir‐
cumstance where each control has an effect.
A.1 The Harlequin MultiRIP without ColorPro
In the Harlequin MultiRIP without ColorPro enabled, UCR and black generation follow the settings in the Output Controls for RGB section of the Color Setup dialog box. You can select this from Color >
Color Setup Manager > New ‘No Color Management’ Setup, or by clicking the Color Setup Manger icon from the tool bar or the Separations, Screening & Color section of the Edit Page Setup dialog.
It is worth stressing that this black generation affects only RGB color inputs, and only when RGB is expressed in a device‐dependent way. CMYK and device‐independent RGB are not affected by these settings. See “Color Separation” in the Harlequin MultiRIP OEM Manual for details.
A.2 The Harlequin MultiRIP with ColorPro enabled
In the Harlequin MultiRIP with ColorPro enabled and suitable profiles installed there are several possibilities:
•
ColorPro and an ICC profile
The black generation is defined in the output profile and cannot be altered.
•
ColorPro and a device link profile
The color transformation is specified in the device link profile and cannot be altered. •
ColorPro with the RGB input profile set to (None)
In this case, UCR and black generation follow the settings in the Output controls for RGB section of the Color Setup dialog box. See the “Output Controls for RGB” on page 38 for details.
•
ColorPro and a Harlequin profile
The black generation is defined in the rendering intent. If you are using ColorPro, you can influ‐
ence this by choosing values for Black generation and Maximum ink in the Color Rendering Intent Details dialog box. See page 28 for details.
When the ColorPro option is enabled, that option processes all device‐independent color inputs. The information in the job is overridden by ColorPro if you select the Override color management in job check box in the Color Setup dialog box. If you leave this box unselected, Appendix C, “Jobs Containing Color Management Data” describes the rules used to decide how the data in the job takes effect. INDEX

Appendix B – Creating a Logo
ColorPro cannot guess when a graphic is a logo; it must be explicitly told.
To identify a logo, use the setcolorrenderingintent operator (a Harlequin extension to the Post‐

/Logo setcolorrenderingintent
should appear at the start of the file. The only way to insert this line is to edit the file by hand.

Appendix C – Jobs Containing Color
Management Data
Settings within the Harlequin MultiRIP, in the PostScript‐language or PDF job, and in the images themselves can all control the processing of images in a job. This appendix describes the settings that influence this processing and explains which setting takes precedence in each particular case. “Summary of options” on page 47 shows a summary in tabular form. Note: Some options apply only to EPS files produced by Adobe Photoshop. In addition, “Embedding ICC profiles in Photoshop images” on page 48 describes how to select the correct ICC profile for embedding in Photoshop 5.0 images and higher.
“PDF color management” on page 48 describes the cases specific to PDF jobs.
C.1 PostScript-language jobs and image files
The Harlequin MultiRIP checks the following when processing jobs containing Photoshop EPS images or TIFF/JPEG images containing embedded ICC profiles:
•
Does the current page setup use a color management option? •
Is the Override color management in job check box selected in the Color Setup dialog box?
•
Does the image contain a PostScript color space array? (Photoshop EPS files only.)
•
Does the image contain an embedded ICC profile?
•
Is the UseCIEColor parameter set to true in the job?
C.2 Page setup uses a color management option
If the current page setup uses a ColorPro setup or No Color Management setup or both and the Override color management in job check box is selected in the Color Setup dialog box, the Harlequin MultiRIP uses the settings in the Color setup. It treats the job as CMYK or RGB.
If the current page setup uses a Color Setup but the Override color management in job check box is not selected in the Color Setup dialog box, the Harlequin MultiRIP checks for color management informa‐
tion in the image and the job. It uses the color management information in the following strict order:
•
If the image contains a PostScript color space array (Photoshop EPS files only):
The Harlequin MultiRIP uses the color space array (CSA) to transform the image. It treats the image as a device‐independent color image.
•
Otherwise, if the image contains an embedded ICC profile:
The Harlequin MultiRIP uses the ICC profile to transform the image. It treats the image as a device‐independent color image.
•
Otherwise, if the UseCIEColor parameter set to true in the job:
The Harlequin MultiRIP uses the DefaultGray, DefaultRGB or DefaultCMYK color space resources to transform the image colors. It treats the image as a device‐independent color image.

C.4 Embedding ICC profiles in Photoshop images
This section describes how to select the correct ICC profile for embedding in Photoshop 5.0 images and higher. There are number of dialog boxes that relate to ICC profiles in Photoshop. Here we explain how to set the options in these Photoshop dialog boxes.
•
File > Color Settings > Profile Setup In this dialog box you indicate which types of images should have profiles embedded (RGB, CMYK, Grayscale, and Lab). Also in this dialog box, you can select Assumed Profiles. Note that these assumed profiles are not the profiles that are embedded.
•
File > Color Settings > RGB Setup
File > Color Settings > Grayscale Setup These dialog boxes do not contain an explicit ICC Profile option. However, for RGB and Gray images, Photoshop converts the set of parameters selected in this dialog box to ICC profiles, and it is these profiles that are embedded. You can create ICC profiles directly using the Save... option in this dialog box.
Note that “standard” ICC profiles are not supported in Photoshop 5.0 for RGB or grayscale images.
•
File > Color Settings > CMYK Setup You select ICC profiles and also the Color Management Module using this dialog box. It is these profiles that are embedded.
C.5 PDF color management
PDF jobs can use a variety of color spaces, including device‐dependent spaces such as DeviceCMYK. Typically, when using device‐independent color spaces, PDF version 1.2 files use the CalGray and CalRGB color spaces and PDF version 1.3 files use the ICCBased color space but these usages are under the control of the creating applications—see the Job Options dialog box: for the Advanced tab in Distiller 3.0; for the Color tab in Distiller 4.0. Full use of device‐independent color requires ColorPro to be enabled.

Appendix F – Seeing Color
This appendix gives a brief description of the perception and measurement of color. It forms an intro‐
duction to understanding the issues in color printing, listed in Appendix G, “Printing Color”.
F.1 Perception of color
The perception of color is both biological and psychological. The biological aspect is the eye’s detec‐
tion of certain wavelengths of light. The psychological aspect is the way the sensation of color is pro‐
cessed by the mind. For hundreds of years, researchers have tried to express the human perception of color in objective and quantifiable terms. But since all people vary in how they process color, this has been a formidable task.
From a purely physical point of view, seeing color requires the presence of three elements: a light source, an object that interacts with the light, and a receiver (the eye). An object has a “color” because it absorbs some wavelengths and reflects or transmits others. For example, a tomato appears red because it absorbs green and blue light and reflects red light.
Light, a form of electromagnetic energy, can be described as waves. The length of a wave is its wave‐
length. Wavelengths are measured in nanometers (nm), that is, one millionth of a millimeter. Wave‐
lengths between 400 and 700 nm are visible to the human eye. “Red,” “Green,” and other colors are names assigned to a certain range of wavelength.

Appendix G – Printing Color
This appendix describes the issues in achieving faithful color reproduction and how the treatment of these issues has changed with the availability of digital technology and device‐independent color.
G.1 Issues in color printing
Color printing is a difficult art. At the core is the following problem: how does one person (or scanner, application, and so on) specify a color sufficiently for another person (or printer, monitor, and so on) to reproduce the color as the first person intended.
The color printing process begins with the designer’s ideas and the customer’s specifications. These specifications must be communicated to many people who will render and reproduce these colors on different devices. At each stage of production, output from one process becomes input for the next process. Each of these processes involves color in a different color space; from photographic film to monitor RGB to CMYK printing on different output devices. At each step, judgement on color is made by different viewers under different viewing conditions.
With the proliferation of affordable and quality input/output devices and software packages, users are no longer buying solutions from a single vendor. Rather, they purchase different system compo‐
nents from different vendors and combine the elements to create an integrated process. This creates an increasing need for effective color management.
G.2 Color management
The task of color management is to ensure that color jobs from many different sources and printed on many different devices appear consistent. Color management allows a printer to manipulate any type of color image using any type of device to reliably render the output on any type of media in a seam‐
less manner.
In a traditional setup, a printer who was asked to reproduce a colored picture would scan the picture and use the resulting data to make films and plates for use on a particular press. Since the press was run in a controlled, consistent way, and the scanner was set up to produce good output on a particular press, this method would reliably produce color output. This method, however, has its limitations. A very important limitation is that it does not provide an easy way to ensure consistent color reproduction across different printing environments. In the tradi‐
tional setup, the printing job is not portable to another device or another printing environment. In addition, since prints are manually defined and manipulated with density readings, formal training and education is required for proper handling of print jobs. The biggest advantage in many of today’s color management solution systems is their ability to trans‐
form color into device‐independent color and thereby make the job available for print on any device. For instance, a file that has been proofed on a inkjet printer can be separated, accurately output on a film imagesetter, and passed to a color printing press for printing with good agreement between the initial proof and the final production print run.

G.3 Color gamuts
The color gamut is the entire range of colors possible in a color system such as a photograph, a color monitor, or a printing process. The larger the color gamut, the larger the number of distinct colors (shades) the eye perceives. The human eye is capable of perceiving billions of different colors. In con‐
trast, a color monitor has an upper limit of sixteen million colors that it can reproduce, and a printing press might typically manage five thousand. In the CIE x‐y chromaticity diagram, shown in Figure G.23, the pure spectral colors are distributed around the curved edge of a horseshoe‐shaped chart, with a straight line connecting the blue and red ends of that curve. The strongest (purest) colors are at the edge of the diagram, while mixtures of those colors fill the interior. (All the color names are informal indications of which color appears where; a label like Red is too imprecise for scientific or technical use, unless it is given an accompany‐
ing specification.) The interior colors vary smoothly with position, with the influence of the colors on the edge diminishing as the distance from the edge increases. The small black square near the center of the horseshoe shape indicates white or the absence of a color bias. For example, a straight line passing from the edge at the point labeled Red to the square representing White would pass from a saturated red, through areas with lightening shades of pink, before arriving at white. Similarly, a line staying near the edge and passing from Red to Yellow would pass through areas of red, orange, and yellow.

Figure G.23 also shows the typical gamut of a color monitor. The difficulties of using informal color names become obvious when you know that the corners of this triangular gamut, RGB, are often called Red, Green, and Blue.
Figure G.24 shows that different devices have different color gamuts; colors that can be created on one device can be beyond the capabilities of other devices. Gamuts are influenced by calibration, envi‐
ronment, age of the device, model of the device, and so on.

For a given process, many colors simply cannot be reproduced. Furthermore, different processes can reproduce different colors: given two offset printers, for example, each can probably image some col‐
ors that the other is not capable of imaging. G.4 Device-independent and device-dependent color
A device‐dependent color scheme specifies how to reproduce a color on a particular device, by saying how much of each colorant to use. The limitation of using this scheme is that the appearance of the final output may vary depending on the kinds of CMYK inks used, the color the paper is printed on, the viewing conditions, and so on. (There are similar variations for RGB systems, depending on the display phosphors, monitor settings and so on.) The result is that it is not possible to predict the exact appearance of device‐dependent color jobs until they are printed.
One workaround to using the device‐dependent color scheme is to adapt the job for a particular printer. The original CMYK data is adjusted according to the known characteristics of the output device, and then printed. This scheme works quite well where a job is always printed on the same printer and setup, but if printed on a different printer with a different setup, the job will almost cer‐
tainly look different. A CMYK job will only use the colors in the gamut of a “typical” CMYK printer. If the final medium has a bigger color range, colors are needlessly restricted. A device‐independent color scheme is specified in a general way, independent of the final output device. The work of the International Committee of Illumination (CIE) over the past 50 years has established a number of standards for doing this. One important issue when using the device‐inde‐
pendent scheme is that a job may specify colors that are not within the gamut of the printer. Mapping unprintable colors to printable colors becomes an important science when using device‐independent color schemes. Device profiles — software that translates color data for one device between its native color space and a standard color space (the ICC profile connection space) — assist in this mapping. A device profile is a table or mathematical expression that characterizes the color behavior of a color imaging device. Pro‐
files can be used for scanners or input devices, for monitors, and for printers and other output devices. The ICC (International Color Consortium) has standardized templates for these profiles. These profiles are supplied by the device manufacturer, generated by the user, or sold as part of a color management system. By obtaining a compatible color‐management system and one device pro‐
file for each piece of equipment, you can make that equipment part of the system.
Note: ICC‐compatible profiles that characterize the same device do not necessarily provide and guar‐
antee the same quality.

Device link profiles, despite the similar name, have a different and more limited function. A device link profile translates color data for the native color space of one device to and from the native color space of one other device. Each pair of devices requires a separate device link profile. For three devices, there are three pairs; for four devices, there are six pairs; and the number of pairs rises rapidly. Device link profiles can provide high quality translations, but do not allow for intermediate color manage‐
ment. G.5 Mapping between gamuts
When the input and output gamuts of a system differ, only the colors within both gamuts can be reproduced exactly. Figure G.25 shows the gamut of a monitor (input) and printer (output) in an area where there are other colors, some possible only on the monitor and some possible only on the printer. Some mapping is necessary to reproduce colors possible only on the monitor on the output printer.
Monitor colors out of printer gamut
Printed colors out of monitor gamut
Figure G.25 Detail of out of gamut areas
There are several possible mappings. To show how some of these mappings work, we can consider example colors possible on the monitor but not possible on the printer.
In Figure F.4, colors out of the printer gamut are mapped to a ‘nearby’ point on the edge of the gamut. In this example, A1 is already at a point on the printer gamut limit, and points A2 and A3 are outside the gamut limit. A1 (and all colors within the printer gamut) are reproduced exactly. Points A2 and A3 are mapped to the ‘nearby’ points on the printer gamut, B2 and B3 respectively. This is absolute colorimetric mapping.
Note: In the following diagrams, the direction of the arrows for mapped colors points towards a white point. INDEX

Figure G.27 shows perceptual mapping, a scheme in which there are no abrupt changes in mapping. Colors at the edge of the input gamut (A2) map to the edge of the output gamut (C2). Other out of gamut colors map to colors just inside the output gamut map. Even colors within the printer gamut are mapped, to a degree that depends on their distance from the edge of the printer gamut.
