Color Conversion

GMG ColorServer comes with color profiles and spot color databases (db3) to match all major print standards world-wide. To suit different requirements, the following profile types have already been included. They are available in the Resources section and can be selected for normalizing and converting your files.

Conversion Options

Product Variant	Description
ColorServer (CS)	GMG ColorServer performs fully automatic color space conversions from one color standard to another. CMYK-to-CMYK: For color conversions of CMYK objects from one standard to another, including a gamut mapping, for example, from ISO coated to ISO uncoated. CMYK-to-CMYK Reseparation: For harmonizing GCR/UCR for different output processes under the respective printing conditions (without using an InkOptimizer profile). RGB-to-CMYK Separation: For normalizing different RGB objects into a common CMYK color space. RGB-to-RGB Conversion: For color conversions of RGB objects from one standard RGB color space to another, for example, from Adobe RGB (1998) to eciRGB v2. CMYK-to-RGB Conversion: For color conversions of CMYK objects into RGB.
InkOptimizer (IO)	With GMG InkOptimizer, you can optimize the color composition of printing data for a specific printing condition, for example, ISO Coated v2 (39L) and for a specific Total Area Coverage (TAC). UCR/GCR settings defined within a InkOptimizer profile are applied. CMY color components are replaced by black while exactly retaining the color impression. We recommend using an InkOptimizer profile for web and sheetfed offset, and gravure printing applications for the following reasons. Up to 20% ink savings (depending on the printing process and the medium) Improved and stabilized gray balance If documents from different sources are combined on the press, InkOptimizer makes it easier to harmonize the colors. Tweaking a single color channel will have only minor effects on the gray balance. Improved drying times and run performance, allowing for a higher printing speed, especially for newspaper printing or for printing on media with a lower ink uptake

Depending on license, you can apply ColorServer and / or InkOptimizer profiles. You can also combine ColorServer and InkOptimizer conversions in one preset.

You can use GMG ProfileEditor or GMG OpenColor to create your own color profiles, including MXN profiles for Multicolor Conversion.
