New in ColorServer 5.8

Version 5.8 - November, 2026

SmartProfiler: Create G7-compliant conversions and verify G7 conformance

With GMG SmartProfiler, you can now create G7 Grayscale-compliant conversions with just one click and verify G7 conformance at any time using measurement data.

A comprehensive pass/fail report provides detailed information on the G7 criteria. See here for more information.

Rasterize: PDF/X Processing

The Rasterize option in the PDF Processing Template now supports PDF/X Processing. When enabled, PDF/X compliant files will be color converted from the attached ICC profiles to the specified Output Intent automatically.

There are two options:

• Use PDF/X Processing if possible, else cancel processing
  Files are only converted if an Output Intent ICC profile is attached to it. Otherwise, the job runs into an error.
• Use PDF/X Processing if possible, else the following settings
  If possible, the attached Output Intent ICC profile and source profiles are used to convert the file, otherwise the fallback profiles specified as Target ICC Profile and Input Color Space are used.

Rasterize: RGB Output

The Rasterize option in the PDF Processing Template now supports RGB Target Color Spaces. To convert a file to RGB, select an RGB ICC profile in the Target Color Space dropdown.

Improved manual spot color database sync with OpenColor

The automatic synchronization of spot color databases with OpenColor has been enhanced with a dialog for manually reviewing and applying pending updates, including a display of the synchronization progress. In addition, it is now possible to select and synchronize multiple spot color databases at the same time. See here for more information.

PDF Processing: Preserve object structure when processing files without flattening

Even when processing PDF files without flattening, ColorServer may make changes to the object structure that are necessary to ensure correct color rendering. However, this can limit the ability to edit the converted file later in PDF editors. To avoid this, a new Preserve Structure (No Flattening Only) option is now available in the PDF Processing Template. See here for more information about this option and the possible limitations it may introduce.

Colorful Gamut Mapping for RGB-to-Print Conversion

In SmartProfiler and dynamic RGB conversion, it is now possible to use colorful gamut mapping when converting from RGB to CMYK/Multicolor. This makes better use of the output color space gamut and converts RGB images with higher saturation.

New and Updated RGB-to-CMYK Separation Profiles for Standard Color Spaces

ColorServer 5.8 includes improved and new profiles for converting RGB to common CMYK color spaces. A total of 152 new V7 profiles are available for converting sRGB, Adobe RGB, eciRGB v2, and Display P3 to the following color spaces:

These profiles are used automatically in the All GMG Conversion Profiles ICC replacement rule.

New Profiles for Conversion to eciCMYK v2

New profiles have been added for converting the following color spaces to eciCMYK v2 (FOGRA59):
