METHOD FOR IMPROVING MECHANICAL ROBUSTNESS OF A COLOR PRINT
A method for improving the abrasion resistance of a printed image, the image being processed digitally by a colour management system for a print process comprising a set of colorants, the colour management system transforming a colour of a part of the image into a colorant coverage for said part of the printed image, wherein a sum of coverage values for all colorants in the set of colorants is larger than a user-selectable threshold value. In a preferred embodiment the set of colorants includes a colorless, transparent colorant.
1 . A method for improving the abrasion resistance of a printed image, that results from an image being processed digitally by a color management system for a print process comprising a set of colorants, the color management system transforming a color of a part of the image into a colorant coverage for said part of the printed image, wherein a sum of coverage values for all colorants in the set of colorants is larger than a user-selectable threshold value.
2 . The method according to claim 1 , wherein the set of colorants comprises a colorless, transparent colorant.
3 . The method according to claim 1 , wherein the print process is an ink jet process.
4 . The method according to claim 3 , wherein the colorant is a UV-curable ink.
5 . A color management system, comprising a profiling module and a user interface for setting parameters to control a transformation of a color of a part of an image into a coverage value for said part of the image, the user interface comprising a field for setting a lower limit for a sum of the coverage values for all colorants.
6 . A print system for printing an image on a substrate, the print system comprising a controller for processing digital image data into print instructions, the controller comprising a color management system according to claim 5 .
7 . A non-transitory computer readable medium storing computer executable instructions for applying the method according to claim 1 .
