A method is described of determining stipulated values for the production of multicolor printed copies, in particular for the production of multicolor printed copies on a printing machine working in half-tone, a reflectance desired value being assigned in the case of an original, in at least one image element having given area coverage of the individual colors to be used in the print, and this at least one reflectance desired value being used during the subsequent printing, in conjunction with a reflectance actual value, in particular for the derivation of adjustment commands for the ink feed so that the subsequently produced print satisfies the best possible color and in particular calorimetric agreement with stipulated values specified during the creation of a printed original. According to the invention, this is achieved by the image elements of the original being assigned desired color loci in each case, and from the spectra or color density spectra of the individual colors used in the subsequent print, as well as their proportion of printing area in the respective image elements, a spectrum of color density spectrum, given calorimetric assessment, yields the best possible approximation to the stipulated desired color locus.
