Abstract:
1. Method of generating a printing color profile for printing images with a digital color printing machine, comprising the steps of: calibrating a first color profile for characterizing a multi colorant print on a specific substrate; calibrating a second color profile for characterizing the same multi colorant print with an transparent toner layer on top of the print by use of clear toner test prints; processing all image data on a pixel by pixel basis using a color management module with the first and second color profiles sequentially performed; and wherein the clear printing color profile is determined in that the first color profile color profile is generated for a color print produced on a specific test print material and that a second color profile is generated for a color print image produced with a clear layer on top of the print, and that the clear printing color profile is determined based on the difference between the first and second color profiles.
