About color spaces
●
●
●
Each color library must be associated with a color space. Each color space must be associated with an ICC profile, which is used to populate the colorants list. We recommend that you name color libraries and color spaces according to the associated ICC profile.
With the Color Space Editor, you can create new color spaces or change a color space by editing the component (colorant) names. Changes to the colorant names are written to the associated ICC profile.
The following color spaces are provided with Prinergy, and are not editable or removable:
CMYK—Adobe SWOP sheetfed
RGB—Adobe RGB 1998
L*a*b*—CIELAB 1976 (the Prinergy default)
You are responsible for creating color recipes for the colors in your color space.
About converting color spaces
Using the Color Matcher with ICC profiles (Prinergy-provided or custom), you can convert:
●
●
●
RGB to CMYK: RGB graphics and images can be automatically converted to CMYK.
CMYK to CMYK: The Color Matcher can convert the color space of a PDF file to a color space appropriate for a specific output device.
Device-independent color spaces to a device color space: The Color
Matcher can convert a device-independent color space such as
L*a*b* to a final color space according to the ICC profile used.
●
●
●
The Color Matcher also enables you to:
Map spot colors
Perform overprint conversions
Match colors
776 Chapter 14—Color

Color libraries and definitions
About color libraries and definitions
Use the Color Editor to manage color libraries and color definitions in
Prinergy.
Color definitions can improve job color accuracy and consistency by replacing color definitions that are defined in the input file with color
781
782 Chapter 14—Color recipes that are specific to the final printing condition (device, media, inks, and so on).
For example, in composite PostScript or PDF files, override inconsistent color recipes in a job with a standard recipe so a spot color can be converted to process or simulated on a proof in the same way throughout a job.
You can also use the Color Editor to store ink parameters necessary for trapping. When trapping, the trapper looks to the color definition
(found according to the library search order specified in the refine process template) for a color's opacity and neutral density values. If the color is not found, the Trapper assumes an opacity value of Normal and determines the neutral density value from the CMYK values in the input file.
Color libraries and alternate color spaces
Color definitions are grouped into libraries. Each color library is associated with an alternate color space. Each alternate color space
(ACS) is associated with an ICC profile, which is used to populate the list of colorants. We recommend that you name color libraries according to the associated ICC profile.
The Color Editor uses the following types of color libraries:
●
●
Factory libraries—are populated from named spot color systems— for example, PANTONE. Factory libraries are preloaded into
Prinergy, and are available to all jobs.
User libraries—are libraries that you populate
○
○
Global tab—contains color definitions that are available to all jobs in the system.
Job tab—contains color definitions that are available only to the job for which they are defined. Job-specific color definitions override global color definitions of the same name.
Important: When you remove a user library, all color definitions in its global and job-specific libraries will be deleted. You will be prompted to confirm.
Within a user library, you can copy colors between the Global tab and the Job tab. By copying a color to the Global tab, you make the color available to all jobs. By copying a color to the Job tab, you can customize the color definition for the job without affecting the color definition for other jobs.
You cannot copy colors between user libraries. But you can import and export user libraries between Prinergy systems.
About how Prinergy searches for color definitions 783
When you export an entire job in Prinergy, the export includes jobspecific color definitions and their ACS and ICC profiles but does not include global color definitions.

About the PANTONE library on page 784
About how Prinergy searches for color definitions
When Prinergy looks for a color definition, it uses the color library search order as specified in the Spot Color Handling section of the job's refine process template.
PANTONE colors and related suffixes
Because a PANTONE color may have different suffixes, yet still have the same recipe, Prinergy will search for the different permutations of a
PANTONE color name if it cannot find an exact match. For the list of related suffixes, see the Auto-Resolve Spot Color Naming Conflicts check box description in Spot Color Handling Section of the Refine
Process Template.
Color search order
Prinergy performs the search by:
1. First searching (for the exact color name) in the Job tabs of the libraries in the listed order
2. Then searching (for the exact color name) in the Global tabs of the user libraries and factory libraries in the listed order
3. Then, if a PANTONE color, searching for permutations of the
PANTONE color name in the Job tabs of the libraries in the listed order
4. Then, if a PANTONE color, searching for permutations of the
PANTONE color name in the Global tabs of the user libraries and factory libraries in the listed order
For example, if the libraries are listed in the following order:
784 Chapter 14—Color
Listed Order userlib1 factorylib1 userlib2
Search Order
Job tab of userlib1 (exact match)
Job tab of userlib2 (exact match)
Global tab of userlib1 (exact match) factorylib1 (exact match)
Global tab of userlib2 (exact match)
Job tab of userlib1 (loose match)
Job tab of userlib2 (loose match)
Global tab of userlib1 (loose match) factorylib1 (loose match)
Global tab of userlib2 (loose match)
About the PANTONE library
The PANTONE library of color definitions is a standard feature of
Prinergy. It is loaded into the global color database. You access the global color database when you're using the Color Editor.
The PANTONE library consists of color definitions for 15,751 different
PANTONE color names. Most of the colors are defined in the L*a*b* color space; some are defined in the CMYK color space. Each
PANTONE color name has only one color definition, also known as a color recipe.
Note: When you install the PANTONE library using Prinergy Administrator, you can choose whether to load the CMYK or L*a*b* color systems. See the Prinergy
System Administration guide for more information.
Because Prinergy uses the PANTONE library, it lets you create proofs that are even closer to the color produced by presses.
PANTONE library with QuarkXPress, Illustrator, and
Photoshop
The PANTONE library is intended for use with files produced by
QuarkXPress, Adobe Illustrator, and/or Adobe Photoshop, which all contain the PANTONE library. In these desktop applications, when you use a color from the PANTONE library, the color name is captured in the file. QuarkXPress, Illustrator, and Photoshop all add characters to the end of PANTONE color names. Prinergy knows the rules by which each of these desktop applications change PANTONE color names.
When you add the file to Prinergy and refine it, Prinergy recognizes the
PANTONE color name, matches it to the PANTONE color in the
PANTONE library, and uses the color recipe from the PANTONE library.
Adding or changing colors in separations 785
You have the option of changing the color recipe for the PANTONE color for the job. The modified color recipe is stored with the job and does not override the color recipe in the PANTONE library.
PANTONE library with other desktop applications
Prinergy recognizes PANTONE color names in files generated by
QuarkXPress, Illustrator, and Photoshop, because Prinergy knows the rules these applications use to specify PANTONE color names. If you are processing a file in Prinergy that is produced by any other desktop application, such as CorelDRAW, you will need to know the rules the applications use to name the PANTONE colors in their files to successfully use the PANTONE library in Prinergy.
PANTONE library presence in Prinergy
The PANTONE library is invisible to you until you've refined files that contain PANTONE spot colors or you have manually added separations with PANTONE color names to a job. When a PANTONE color exists in a job, you can see its color recipe when you display the Color
Separations dialog box or the Color Mapping dialog box.
The refining process and Color Combiner both use the PANTONE library.

Select one of the following opacity options:
Not Specified: Opacity is not specified.
Normal: The color is treated as translucent. Normal colors, or objects covered by or placed on top of Normal colors, may be trapped.
Transparent: Transparent colors are not trapped.
Opaque: Opaque colors, or objects covered by Opaque colors, are not spread. Other colors may trap to Opaque colors, and objects covered by Opaque colors may be choked back.
Opaque Ignored: Opaque Ignored colors are not spread. Other colors do not trap to Opaque Ignored colors.
die line-The color is not trapped. For composite proofs, the color knocks out. When outputting separations, the system treats the color as an overprint ink.
Neutral Density
(Also see
About neutral density on page 256
)
Specifies the neutral density for the color.
Note: Unless you need to specify a special neutral density for trapping purposes, we recommend that you leave this blank. The neutral density values are determined from the process color recipe.
Treat Color As Black
This check box is available only for the PDF Trap Editor.
You can specify that a colorant (usually only a spot color) be treated as though it was black. The settings in the Black area of the Trap section of the refine process template determine how
Prinergy handles black objects.
●
●
Notes:
●
Normal inks can be trapped as black if set to Treat as Black.
Other colors trap to Opaque inks because Opaque inks are always treated as black.
Transparent or Opaque Ignored inks are never treated as black.
Alternate Color Space Name
Specifies an alternate color space for the color, for example,
RGB, CMYK, or L*a*b*.
The components below the Name box specify the percentage
(or quantity) of each component forming the color recipe. For

Separations
About color separations
●
●
●
You can work with color separations in the Color Separations dialog box to:
View the pages that a color is on
Specify whether or not a color is output
Specify how to handle spot colors
●
●
Spot color mapping set through the Color Separations dialog box applies to:
Imposition proofs and final output only
Raster output and separated vector output (composite vector output is not supported)
Note: In general, the Color Matcher has better control of spot color mapping/ conversion than the RIP does. Therefore, to ensure proofs match plates with respect to spot color handling, it is advisable to do as much processing of spot colors (mapping one spot color to another, conversion of spot color to process) in the refine stage, not during final output.
Identifying common separations 799
Resetting initial separations
You can reset the separations in theSeparations view to the page colors defined in the pages assigned to the page sets. This is useful:
●
●
After you add an imposition plan to a job that contains an existing page set causing the Separations view not to display any separations.
To reset the separations in a job after you've created color mappings.
Common separations
When you have used a versioning imposition with layering you can identify separations as base, common, or unique. The labels appears in
the Common column in the Separations view on page 46
of Job
Manager.
Color print order
Color print order is the order in which the system handles color separations. It is useful in two situations:
●
●
Imposition proofs and final output-Color print order controls the order in which Prinergy outputs color separations from a signature for a job. The order you specify displays in the Separations view.
Color mapping-Color print order controls the order in which
Prinergy traps the colors from a signature for a job. Since the firstdown ink on the substrate must pull the second-down ink from the plate or cylinder, knowing which colors these are can help you avoid unsightly trap colors.
Identifying common separations
This procedure applies only when you have used a versioning imposition with layering.
In the Separations view of Job Manager, perform one of the following actions:

802 Chapter 14—Color
Note: Impositions usually have marks with colors: CMYK colors, as well as generic spots. The generic spots usually follow a specific naming convention (example, "Spot1", "Spot2", and so on). When you import an imposition, all the imposition colors are set to Do not output to avoid unnecessary and wasted plates. When you assign a page to an imposition, Prinergy automatically turns on the necessary colors in the imposition as well. This enables the imposition marks to reflect the colors on the pages. Prinergy also automatically maps the imposition mark spot colors to the page spot colors. For example, it will automatically map imposition mark "Spot1" to page color "PANTONE Reflex Blue C". If necessary, you can override this the automatic mapping by using the
Separations view of Workshop.
Add Separation

Spot colors
About reducing and preserving spot colors (overview)
●
●
●
When job files contain spot colors, you need to figure out whether to reduce them.
You can handle a spot color in several ways:
●
Preserve it so that it remains in the job files, appears in a proof, or appears in final output.
Convert it to process color.
Map it to another spot color.
Omit it from proofs or final output.
●
●
You can handle spot colors at several stages in the workflow:
●
Refine: See About Reducing and Preserving Spot Colors During
Refine.
Proof: See About Reducing and Preserving Spot Colors in Proofs.
Final output: See About Reducing and Preserving Spot Colors in
Final Output.
If the Answer to This Question
Will the colors in your final output be the same as the colors in your input files?

About Color Combiner
Color Combiner is a Prinergy feature that lets you simulate the hue of spot colors in output-including traps, knockouts, and overprints, using only the standard four process colors: cyan, magenta, yellow, and black. Color Combiner works equally well on all types of jobs— composite, separated, vector, or copydot.
When used with the Kodak Trendsetter Spectrum digital halftone proofer, Color Combiner lets you simulate the hue and halftone dot structure of spot colors— for example to help you predict moiré in duotones. The Trendsetter Spectrum proofer provides a proof using the same number of donors as a regular four-color job.
Because Color Combiner works with copydot data as well as CT/ vector data, you may proof spot color copydot work using standard process colors and be assured the proof accurately reflects the printed piece.
How does Color Combiner work?
Color Combiner uses combinations of CMYK to simulate spot colors in a job. Each spot color (for example, Bright Red #10), must have a single combination of CMYK associated with it —for example, C = 2, M = 85,
Y = 96, and K = 0. You can specify the color association using the
Color Editor.
When you enable Color Combiner, it uses the CMYK combinations associated with spot color names. If Color Combiner cannot find a
CMYK entry in the color database for a spot color, it outputs the spot color in an easily identifiable bright green color. The bright green color warns you that the CMYK combination for the spot color is not in the color database. A yellow warning triangle also appears beside the spot color in the Color Editor dialog box.
806 Chapter 14—Color
Enabling Color Combiner
●
●
●
You can enable Color Combiner in any one of the following process templates:
Loose page output
Imposition output
Final output
To enable Color Combiner in these process templates, in the Render section, select the Do Separations check box and select the Always
Use Color Combiner to Convert Spots check box.
Finding the right color combination
Each CMYK proofing device requires a slightly different combination of
CMYK to simulate a particular spot color because the individual colorants used for CMYK differ for each proofer. To get a quicker match to spot colors within the gamut of the proofer, use an ICC profile for the proofer. To do this, measure the L*a*b* absolute color value of the spot color that you want to match. Then, use stand-alone software such as Kodak Profile Wizard, X-Rite ColorShop or Praxisoft VectorPro to achieve the closest CMYK combination for the L*a*b* color space.
Limitations of Color Combiner
Color Combiner has the following limitations:
●
●
●
●
●
It can exactly simulate only spot colors that are within the color gamut of the proofer. For example, it cannot arbitrarily produce a brighter red spot color.
It can produce only a best approximation of colors that are outside the color gamut of the proofer.
For best quality, use Color Combiner for AM spot color screens up to and including 175 lpi on the Trendsetter Spectrum proofer.
If there are many overprints in the same area, the donor pigment may run out. For example, if a solid CMYK 10-60-80-10 spot color simulation overprints a solid CMYK 10-80-10-5 spot, there will be an area where magenta is maximized at 100, instead of 140. This is the tradeoff for using only one set of media.
For best results, use Color Combiner only with Staccato-qualified halftone proofing media.
When not to use Color Combiner
There are a few instances where you should not use Color Combiner. In that case, clear the Always Use Color Combiner to Convert Spots check box.
About reducing and preserving spot colors during refine 807
●
●
For example, do not use Color Combiner if all of the following conditions are true:
●
You are outputting to a 1-bit screened format and sending it to a device that is incapable of imaging the Staccato dots that Color
Combiner uses in this situation.
Input files are composite.
All spot colors are set to Opaque in the color database, or a spot color is not in the color database and the default value is Opaque.
In this case, the Adobe renderer can extract color recipes from the refined PDF file.
Note: If input files are separated, or if spot colors are not set to Opaque, the Color
Combiner is used even if the Always Use Color Combiner to Convert Spots check box is cleared.
About reducing and preserving spot colors during refine
When you refine input files or pages you can reduce spot colors by converting them to process color or mapping them to other spot colors.
If you preserve or reduce spot colors during refine, it permanently affects the resulting PDF, which is often called the digital master. If you reduce spot colors, they are no longer present when you generate proofs or final output. The original input files remain unchanged.
Preserving spot colors during refine
Reducing spot colors during refine
When to preserve or reduce spot colors during refine
Preserve a spot color during refine in these situations:
●
●
The spot color will be used in the final output. For example, if a customer expects the logo on marketing materials to be displayed in a specific PANTONE color.
You use a late-binding workflow. Some printers prefer to preserve color information as long as possible. This means that they delay color conversion and color reduction until the proofing or final
808 Chapter 14—Color output stages. This is called a late-binding workflow, because the job files are not tied to a specific output device until necessary.
CAUTION: It is better to reduce spot colors during refine—not during proofing and final output—because it ensures consistency between proofs and final output and because color conversion is better in the refine process than in the proofing and final output processes.
Reduce a spot color during refine if the spot color will not be used in final output—for example if a customer mistakenly added a spot color to the files.
How to preserve spot colors during refine
To preserve all spot colors during refine, change a setting in the Spot
Color Handling section of the refine process template.
If you preserve spot colors, you also need to manage the definitions of the spot colors:
●
Make sure the spot colors in the files are defined in the Prinergy color database. You can do this while refining or separately. For instructions on adding colors independent of any process, see
Managing Color Definitions.
●
Make sure the spot colors in the files have the same name that the color has in Prinergy. If a customer uses a different spelling or name for a color, you can point the customer's color to the Prinergy color during the refine process.
How to reduce spot colors during refine
You can reduce spot colors during two types of refine processes:
●
●
By refining the input files. If you know in advance that the input files have unnecessary spot colors, you can eliminate them immediately when you refine the input files.
By refining the pages. If you do not know what the files contain, you run two refine processes. This is the most common situation. You refine the input files without handling color in any way. After looking at the resulting pages, you then refine the pages and handle any color issues in them. Typically, you create a refine process template specifically for this purpose with a name such as 2ndRefine-
MapColors.
You can reduce spot colors during refine in two ways:

If you convert spot colors to process color, the Color Combiner can simulate the hue of spot colors in a proof-including traps, knockouts, and overprints-using the standard four process colors.
When to preserve or reduce spot colors in a proof
Preserve spot colors in proofs if you want to see the spot colors in the proof and the printer supports the spot colors.
Reduce spot colors in proofs in these situations:
●
●
The proofer supports only process color. Most proofers handle only process color. When generating a proof on these proofers, convert all spot colors to process color.
The spot color requires special handling. Certain spot colors can be challenging to proof. Here are a few special spot colors and how to handle them:
With This Spot Color Handle It This Way
Metallic and other colors that are hard to convert to process color
Varnish
Die line
White background on clear plastic
Omit the spot color or output it separately.
For example, if the proofer uses donor sheets, omit the spot color when you generate donors for the process colors and then generate the metallic spot color as a separate donor sheet.
Output the spot color separately as an overlay.
This is useful because varnish spot colors usually have an arbitrary color value, such as 2 percent magenta, that makes the varnish visible in the job files. If you leave the spot color in the proof, it may cover objects that you want to check. If you convert the spot color to process color, its color value changes the value of the process color.
Omit the die spot color from the proof.
Omit the white spot color or output it separately.
For example, with a proofer that uses donor sheets, use a white or yellow donor to make a separate separation that is not laminated together with the process colors.
This is useful because the white spot color usually has an arbitrary color value, such as 10 percent magenta, that makes the spot color visible in the job files. If you leave the spot color in the proof, it may cover objects that you want to check. If you convert the spot color to process color, its color value changes the value of the process color.
●

Spot colors were introduced in marks. If the marks (for example, the color bar) from the imposition plan contain spot colors that you do not want in the proof, do not output the spot colors.
You use a late-binding workflow. Some printers prefer to preserve color information as long as possible. This means that they delay color conversion and color reduction until the proofing or final output stages. This is called a late-binding workflow because the job files are not tied to a specific output device until necessary.
Caution: It is better to reduce spot colors during refine—not during proofing and final output—because it ensures consistency between

Reducing spot colors (workflow)
Requirements: Start with a job that already has input files.
This procedure summarizes how and when you can reduce spot colors in a job.
1. (Optional) If you know the definitions of the spot colors, add the colors to the color database, including color names that you want to alias other colors to.
Alternatively, you can add colors later, when you refine.
2. Refine the input files, preserving the spot colors.
3. Review the spot colors in the pages.
4. Refine the pages to handle spot colors: a. If the pages contain spot colors that will not be plated, reduce all spot colors during a refine of the pages, or reduce specific spot colors during a refine of the pages.
b. If a spot color is in the Prinergy color database under a different name, add an alias for the color.
5. Generate loose page output:
●
●
If the proofer supports all of the spot colors, preserve the spot colors in the final output.
If the proofer does not support all of the spot colors, reduce all spot colors in the proof, or reduce specific spot colors in the proof.
6. Impose the job as required.
Aliasing spot colors to different names 815
7. Generate imposition output:

If the proofer supports all of the spot colors, preserve the spot colors in the proof.
If the proofer does not support all of the spot colors, reduce all spot colors in the proof, or reduce specific spot colors in the proof.
8. General final output.
a. If the proofer supports all of the spot colors, preserve the spot colors in the final output.
b. If you want to reduce spot colors, such as spot colors that were introduced when you imported marks, reduce all spot colors in the final output, or reduce specific spot colors in the final output.
Aliasing spot colors to different names
Use this procedure when a spot color in a file is spelled or named differently from a spot color in Prinergy.
1. Select the input files or pages with the spot colors that you want to affect.
2. Start a refine process on the selected files by dragging the files to the refine process template.
3. In the Start Process dialog box, click Color Mapping.
This opens the Color Mapping dialog box.
4. Click Add Alias.
5. Type a name for the alias color in the Enter a new color alias box, and then click OK.
Prinergy searches for the name in the color libraries selected in the refine process template.

You can modify and save the process template before you start. Start the process using the modified process template, and do not click Edit Process
Template in the Start Process dialog box.
Changes made in the Color Separations dialog box affect all future imposition output and final output.
Note: Impositions usually have marks with colors: CMYK colors, as well as generic spots. The generic spots usually follow a specific naming convention (example,
"Spot1", "Spot2", and so on). When you import an imposition, all the imposition colors are set to Do not output to avoid unnecessary and wasted plates. When you assign a page to an imposition, Prinergy automatically turns on the necessary colors in the imposition as well. This enables the imposition marks to reflect the colors on the pages. Prinergy also automatically maps the imposition mark spot colors to the page spot colors. For example, it will automatically map imposition mark "Spot1" to page color "PANTONE Reflex Blue C". If necessary, you can override this the automatic mapping by using the Separations view of Workshop.
Color Mappings dialog box
Note: The Color Mappings dialog box is a color mapping/color renaming tool. It is not a color removal or extractor tool. This tool is only available for the first refine; the Process Template Editor does not have any knowledge of what colors are in the file. Use this tool to display the available colors to be mapped. You can add more colors from the color database in order to map them on the first refine.
When you remove a specified color, this color is not actually removed. Instead, removal means that you don't wish to map the specified color to anything. Objects with this color are still painted.
Page Color
Lists all the colors found in the selected pages.
When a spot color is found in the selected color libraries, a sample color swatch appears to the left of the color name. If the spot color is an exception, it is named Otherwise and a warning icon ( ) appears to the left of the color name.
After your first refine, you can redefine the Otherwise entries as spot colors in your color database, or redefine them as Convert to Process. After you perform the second refine, all the previous exceptions noted as Otherwise should be eliminated.

About Spotless Extended Color Management
Spotless Extended Color Management expands the functionality of
Prinergy beyond CMYK to allow extended process color sets to enhance quality and increase the number of spot colors that can be replaced with process colors.
In Prinergy, spot color recipes are replaced with process color recipes
(also known as color builds) for a specific ink set. On press, spot color inks are replaced with process color inks, giving spot color performance on a process color budget.
For example, an extended process color set could consist of six process colors: cyan, magenta, yellow, black, orange, and green (CMYKOG).
For this process color set, the recipes for all the colors are comprised of combinations of CMYKOG. You store the color recipes in the Color
Editor in Prinergy Workshop and use them to convert spot colors to process color.
For more information, see the Spotless Extended Color Management documentation.
Die line and varnishes
About die line and varnish colors
A die is a series of knives used to cut shapes from a press sheet, and a die line is a line that represents the position of the various knives and is used to guide the die in cutting a press sheet. Die lines are usually created using a Computer Assisted Design (CAD) program and included in the original input files added to Prinergy.
A varnish or overprint coating is created to protect or improve the visual appeal of a printed page, and is used to protect the print, for decoration, adhesion, or for resistance to oil or moisture.
Die lines and varnishes need specific opacity attributes to ensure the file prints correctly. For example, die lines cannot be trapped; they need to be set to knockout on composite proofs and as an overprint ink when outputting separations. Varnishes shouldn't display on composite proofs.
Note: The die line or varnish color must have exactly the same name in Prinergy as it has in the input file. For example, if the native application file includes the colors
Die and Varn, the color database in Prinergy must include a color Die or Varn.
If a die line or varnish color is not defined in the color database,
Prinergy treats it as a separate spot color and the color may print with incorrect attributes.
Setting die line and varnish colors 831
Setting die line and varnish colors
1. (Optional) Add a color for the die line or varnish to the Global tab of the Color Editor with a name such as Die or Varn.
a. Set the Opacity of a die line color to die line.
b. Set the Opacity of a varnish color to Transparent.
This step is optional because you can also add the color while you refine in Step 4.
2. Refine the pages where you want to use the die line or varnish by starting a refine process template on the pages.
3. In the Start Process dialog box, click Color Mapping.
4. In the Color Mappings dialog box, perform one of the following actions:
If the Die or Varn

Using ColorFlow software
The ColorFlow 1.2 software is integrated with Prinergy.
The ColorFlow software delivers color relationship management that unifies color control elements—such as ICC profiles, DeviceLink profiles, and calibration curves—and manages the relationships between color control elements and device print conditions.
Specifically, ColorFlow simplifies the process of setting up color and ensuring that Prinergy jobs are processed using the correct color settings.
832 Chapter 14—Color
Complete these steps, in this order
Install the ColorFlow software on client computers.
Getting started with ColorFlow
Notes
Consider whether you will import
Harmony tonal calibration curves.
Configure ColorFlow.
As part of Prinergy, the ColorFlow Workflow Edition software and colorstore database are automatically installed on the Prinergy primary server. The ColorFlow server runs as a process on the Prinergy primary server.
You must install the ColorFlow software on one or more client computers that connect to a Prinergy server.
Note: Only one user can modify the colorstore database at one time.
Therefore, only one ColorFlow client computer can be running at a time.
For instructions on installing the ColorFlow software on client computers, see the ColorFlow User Guide.
Decide whether you'll use the ColorFlow software to create and manage color control elements, or import existing Harmony tonal calibration software curves. If you use Harmony, you can delay using some capabilities of ColorFlow until you have time to print and measure charts with your device conditions.
Note: When using ColorFlow with Prinergy, we recommend building new curves rather than importing existing Harmony tonal calibration curves.
For more information about importing Harmony curves, see the ColorFlow
User Guide.
a. Create a color setup. A color setup is the virtual structure that you build to define the color relationships among the devices in your printing task. It includes devices, device conditions, a simulation target, and color control elements, such as DeviceLink profiles and curves.
A color setup manages how its device conditions simulate the primary color output (PCO). If you edit the color response of a device condition, ColorFlow ensures that related color control elements in the color setup are updated to reflect the edit.
b. Add device conditions. A device condition is the combination of a device and the operating conditions in which the device captures or produces an image. It has a measurable color response.
A device condition can include more than one device. If it does, all devices must have the same device type and must use the same consumables and operational settings. The devices must be able to be calibrated to yield a similar color response. Note that this applies to curve-controlled devices only.
For more information about configuring ColorFlow, see the ColorFlow User
Guide.
Using ColorFlow software 833
Complete these steps, in this order
Measure or import the color response of your device.
Define simulation and conversion settings.
Notes
●
●
Perform either of the following actions:
Create and measure a ColorFlow characterization chart.
Import an existing measurement set.
The attributes of the chart must be suited to the inks you are using on the output device, your measuring device, and the size of your press.
For more information about measuring color response, see the ColorFlow
User Guide.
Use the Simulation Definition dialog box in ColorFlow to control how a primary color output (PCO) simulates the color target. ColorFlow can perform the simulation using tonal curves or DeviceLinks or a combination.
a. In the Target list, select the color response whose colors the PCO will attempt to simulate. Often this will be an industry reference.
b. Using the Curves slider (for offset presses and halftone proofers only), select how you want to use tonal curves. For an explanation of each option, see the ColorFlow User Guide.
c. Using the DeviceLinks slider, select how you want to use DeviceLinks.
For some types of devices, not all values are available. Because the
DeviceLink is used in the context of a simulation, the DeviceLink source is the color space selected in the Target list; the destination is the device condition inside the PCO. For an explanation of each option, see the ColorFlow User Guide.
For more information about simulation and conversion, and the options in the Simulation Definition dialog box, see the ColorFlow User Guide.
Using ColorFlow in Prinergy
After you have configured the ColorFlow software, you can use the
ColorFlow settings in the refine, loose page output, imposition output, and final output process templates to apply color control elements during processing.
In the refine process template, you select a color setup. The available color setups are in the ColorFlow colorstore database on the primary server. When a page is refined using the refine process template, the color setup specified in the process template is assigned to the page.
In each output process template, you select the Color Setup, Device,
Device Condition, Plate Setup, and Plate Line color control elements.
During output processing, the color setup assigned to each page during refining defines the specific color control elements that are applied on output, unless you choose override the color setup tagged to the file during refine.
In addition, when you create a new job, you must enable ColorFlow in the job and select a default color setup for the job. You do this in the job's attributes. To successfully process job files with ColorFlow
834 Chapter 14—Color enabled, you must configure the process templates to use ColorFlow
and enable ColorFlow in the job.
When a job's pages are refined using a refine process template in which you have enabled ColorFlow, the color setup that is assigned depends on the ColorFlow settings in the refine process template:
●
●
●
If the refine process template indicates to use the default color setup selected for the job, the job's color setup is assigned during refining.
If a color setup is specified in the refine process template, the settings in the template override the default color setup selected for the job, and the color setup specified in the refine process template is assigned.
If a color setup is specified in the refine process template but
ColorFlow is not enabled for the job, refining will fail. For a job to be processed using ColorFlow, the job must be ColorFlow-enabled and a default color setup must be selected for the job, even if the default color setup is not assigned during refining.
In Job Manager, the Color Setup column in the Pages pane indicates the color setup assigned to each page.
Note: If the refine process template is not ColorFlow-enabled but the job has a default color setup selected, what happens during refining depends on whether the Match Colors option is selected in the process template. If Match Colors is not selected, the job's default color setup is registered with the refined files, but no color conversion is applied. If Match Colors is selected, refining will fail.
It is also possible to change a refine process template's ColorFlow settings when you refine specific pages, to change the selected color setup. This is useful when you plan to print parts of a job differently, such as on different presses or with different ink sets. For example, for a book that consists of a cover and body pages, you might want to print the cover CMYK but print the body pages in black only.
Note: After you run a job with ColorFlow enabled, you cannot rerun the job without ColorFlow enabled, unless you re-create the job.
Setting the halftone output modes
You can select one of four modes for output to halftone devices or files, in the output process template. These modes control the curves that are applied upon output, corresponding to your output goals.
Print Production
Reflects the standard operation of Prinergy and ColorFlow for production. When this option is selected, a print calibration curve and a plate calibration curve are applied to each output separation.
Using ColorFlow software 835
Print Characterization
Is used to print and measure the response of a print device.
When this option is selected, a device curve and plate calibration
curve are applied to each output separation.
Plate Verification
Is used to verify the linear response of plates produced by a particular plate line (consisting of the computer-to-plate device, plate processor setup, and chemistry), with a selected screening system. When this option is selected, only the plate
calibration curve is applied to input tints of all separations.
Plate Characterization
Supports imaging and measuring the uncalibrated (or intrinsic) response of a plating line, such that a plate linearization curve can be computed. When this option is selected, no calibration curves are applied to input tints of any separations.
Applying ColorFlow curves and making tonal adjustments
If a printing plate has imaged and run on press, but the press is not printing with the desired response, you may need to recreate the plate using a different ColorFlow curve channel for one or more separations.
You can also make tonal adjustments to the assigned ColorFlow curve channel. These adjustments, made on-the-fly from the Start Process dialog box, are appended to the ColorFlow calibration curves and have no effect on ColorFlow colorstores.
ColorFlow and archiving
If you retrieve an archived job for which ColorFlow is enabled, the
ColorFlow server will request the name of the color setup and the number of the Snapshot that was used to initially process files within that job. If you have modified any of the elements within the color setup from the initial time of output, these modified elements will be used to output the archived job.
In addition, if the initial color setup was deleted or renamed, the job will fail processing. If you want to change a color setup, duplicate the original one and make changes to the duplicated and newly named color setup. You can use the Allow undefined color setup or color
setup mismatch check box to output the archived job when the selected color setup differs from the color setup assigned by the refine process.
ColorStore database and backups
If you are running the Windows 2003 Server operating system on your
Prinergy primary server, the Windows NT Backup utility automatically
836 Chapter 14—Color backs up your colorstore database. If you are running the Windows
2008 Server operating system on your Prinergy primary server, the
System Configuration Backup Utility performs the backup process of the colorstore database. If you are using Prinergy with Hot Standby
(Hot Standby combines the basic functionality of failover, allowing a
Prinergy secondary server or render station to take over primary server functions if the primary server fails), the colorstore database is also automatically backed up.

Issues to consider when using ColorFlow
Sharing ColorFlow-enabled work between plants or servers is not possible unless the Prinergy Job Color Setup defaults are changed to an available color setup and the Allow undefined color setup or
color setup mismatch check box is selected in the ColorFlow section in the output process template. Note that output could be significantly different.
If you refine a file with ColorFlow selected, ensure that you select
ColorConvert and Enable ColorFlow if you refine the file again.
Otherwise, an error message appears.
If you want to change the tagged color setup of a PDF file that has been refined, you must refine the PDF file again with a new color setup specified in the process template.
You may encounter a situation in which you have two objects with the same CMYK input in a single PDF file. One object is tagged with an ICC-based CMYK profile; the other object is untagged using
Device CMYK. Conversion of the ICC-based CMYK content will happen via embedded profiles for one object. In contrast, the untagged content will be converted via a DeviceLink from
ColorFlow, if a DeviceLink is present in the selected color setup. To avoid complication, override the embedded profile in the refine process template, which will ensure that all content is managed via
DeviceLink.
If you refine a file with the Prinergy Bypass Refine feature, ensure you refine the file again to tag a color setup in the PDF file.
When using ColorFlow, you can assign one color setup per page in the refine process template. When using the imposition output process template with ColorFlow, you can output an imposition file that has different color setups for each page. When outputting in this situation, ensure that you select a device condition that is contained in all of the color setups assigned to all pages.

ColorFlow 1.2 is integrated with Prinergy . ColorFlow 1.2 supports RGB devices and RGB color inputs, as well as CMYK devices and CMYK color inputs. You can select default CMYK or RGB source color spaces, and ColorFlow can provide CMYK and RGB device profiles in the
Process Template Editor.

Background
An ICC profile is a color space description that acts as a standard for accurate reproduction of colors across different platforms, devices, and applications, according to the standards of the
International Color Consortium (ICC). For example—an ICC profile that describes a specific RGB device, such as a Kodak EasyShare camera, provides a mapping of the camera's red, green, and blue color space to device-independent L*a*b* coordinates (or CIE
L*a*b* color space).
A PDF file is composed of many objects, and each object may have come from a different source—for example, an RGB image captured from a digital scanner or digital camera, CMYK graphics from
Illustrator, and so on. Each of these objects may be tagged with an
ICC profile.
●
Prinergy refine process template setup
You can set up color conversion either with or without ColorFlow.
●
When you are setting up a refine process template without
ColorFlow, the ColorConvert section allows you to select ICC profiles for color converting RGB and CMYK images and graphics.
These ICC profiles are only used by the Color Matcher JTP when an object in the PDF file is not tagged with an ICC profile. In the case of tagged PDF content, the ICC profile settings in the process template are ignored by the Color Matcher JTP, and the tagged profile is used.
Note: You can also use a DeviceLink profile that includes both the source and the destination ICC profiles.
In a ColorFlow-integrated environment, the color conversion that takes place is to the primary color output (PCO) profile. In Prinergy, a ColorFlow device condition is a named instance of a CMYK device color response with an ICC device profile. For example, FOGRA 39 is a built-in device condition for which ColorFlow can provide a
CMYK device profile to Prinergy.
The following table summarizes how to configure the two options:
838 Chapter 14—Color
For this option
To use ColorFlow device conditions for color conversion
Do this a. In the ColorConvert section of the refine process template, in the
Match Colors section, select the Enable ColorFlow check box.
b. From the Snapshot list, select the desired snapshot from ColorFlow.
c. From the Color Setup list, select the ColorFlow color setup from those available in the selected snapshot.
d. Select each image type for which you want to enable ColorFlow color conversion, by selecting the relevant check boxes—CMYK Images,
CMYK Graphics, RGB Images and RGB Graphics.
e. From the lists next to the image type check boxes, select a ColorFlow device condition.
To use ICC profiles or DeviceLink profiles for color conversion
The device conditions are the conditions that have been configured in
ColorFlow, which then supplies the DeviceLinks or profiles for the
CMYK-to-CMYK or RGB-to-CMYK conversion.
a. In the ColorConvert section of the refine process template, clear the
Enable ColorFlow check box.
b. Select each image type for which you want to enable color conversion, by selecting the relevant check boxes—CMYK Images, CMYK
Graphics, RGB Images and RGB Graphics.
c. From the lists next to the image type check boxes, select the relevant
ICC profile or DeviceLink profile.
If an object in the input file does not have an embedded profile, the ICC profile selected for that object type is applied.
