Abstract
A process computes a combination of chromatic and achromatic color dots for reproducing an input color signal based on a result of colorimetric measurement for a CIELab value. The process finds the sum of chromatic and achromatic color dot diameters. The process extracts combinations of chromatic and achromatic color dots wherein the sum of chromatic and achromatic color dot diameters is greater than or equal to a specified value. From the extracted combinations of chromatic and achromatic color dots, the process further extracts chromatic and achromatic color signals for recording a combination of chromatic and achromatic color dots containing the minimum achromatic color dot diameter and determines these signals as a color signal.
