Abstract

A process for producing a multicolored print by employing a color scanner that is capable of being profiled and an electronic image processor. Color data pertaining to color fields are taken as the basis for determining an algorithm for the printable color range and the separation, the color data being generated by employing ceramic colors of a multicolor set that are compatible with one another. With a view to producing four-color prints and also, in particular, seven-color prints that are truer to the original, four-color and seven-color sets as claimed are employed such as were taken as the basis for the color fields for determination of the algorithm. By means of seven-color printing, the color space is extended.
