Abstract

Colorimetric values for generating a color separation table, which are obtained by measuring a plurality of color patches included in a color chart, are input, and measurement values corresponding to the input plural measurement values other than supervised input measurement values are estimated using supervised measurement values. Then, color differences between the estimated measurement values and the input plural measurement values other than the supervised measurement values are calculated. Based on the color differences, it is determined whether printing of the plurality of color patches or measurement of the plurality of color patches has been performed correctly.
