Abstract

In a method to convert color-describing input print data suitable for graphical output with aid of an output apparatus into color-describing output print data, color proportions, defined by the input print data, of at least one region to be inked with at least two color separations, are determined, and a color space value to be generated with aid of the color separations is determined. An association rule is determined to convert the input print data into the output print data while retaining the color space value. A total areal coverage of areal coverages defined by the output print data of the color separations to generate the color space value is reduced relative to areal coverages of the color separations defined by the input print data. The input print data is converted into the output print data with aid of the determined association rule.
