Abstract
A color gamut for each printing mode is maximally used, a color separation table is used, which includes an area (color reproduction maintaining area) for which an image having a color difference of a predetermined value or less between printing modes in a case where the same input value is input is output and an area (area other than the color reproduction maintaining area) for which an image having a color difference of a predetermined value or more between the printing modes in a case where the same input value is input is output. From this, a color matching table can be shared between the printing modes.
