ABSTRACT:
In order to be able to print a prescribed target color with a printing system, the color data of the target color and of the mixed color compounded with parts of the primary colors are compared, and the addition of the parts is varied until adequate similarity has been achieved between the color data of the target color and of the mixed color. In a further step, the mixed color is printed out, the color data of the printed mixed color are identified, and these are compared to those of the target color. Given inadequate similarity, additional parts of the primary colors are added to the mixed color until the respectively printed mixed color has its color data adequately coinciding with the color data of the target color. The mixed color corresponding to the target color is produced from the identified parts and additional parts of the primary colors.
