Abstract
A method for color regulation of reproduction copies of a printing press prints a substrate, which appears dark in a standardized color measurement, with at least one printing ink which is lighter than the substrate. At least one color value of the printing ink is determined from a measured variable, and the color value of the at least one printing ink is regulated with the aid of a fixed reference value of a color locus in the color space which is lighter than the printing ink.
