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.
You can set up color conversion with or without ColorFlow.
- When you are setting up a refine to PDF process template without ColorFlow, the Match Colors 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. Note also that the tagged profile can be ignored if Strip Embededded Profile is enabled. - 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:
For this option | Do this |
|---|
To use ColorFlow device conditions for color conversion | - In the Match Colors section of the refine to PDF process template, select the Enable ColorFlow check box.
- From the Snapshot list, select the desired snapshot from ColorFlow.
- From the Color Setup list, select the ColorFlow color setup from those available in the selected snapshot.
- 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.
- From the lists next to the image type check boxes, select a ColorFlow device condition.
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.

To use ICC profiles or DeviceLink profiles for color conversion | - In the Match Colors section of the refine to PDF process template, clear the Enable ColorFlow check box.
- 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.
- 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.
