Abstract
A method for producing a proof, having proof printing inks cyan-P, magenta-P, yellow-P, black-P, for an edition printing process, and primary printing inks CMYK and a secondary printing ink RGB, converts edition printing process printing inks with association tables into proof printing process printing inks, for combinations of input color components, associated output color components being stored in the association tables. Reducing storage requirement of association tables having >four input color components is done by dividing into a plurality of association tables. Up to four printing inks are printed in the edition printing process during color separation for the edition printing process by GCR and CCR application. Factors of gray and color component replacement are chosen as a function of chroma of a color to be printed. CCR is applied only to a color to be printed to which a GCR with a factor of 100% has already been applied.
