ABSTRACT:
The present invention provides color reproduction method to reproduce arbitrary colors at high precision simply without requiring a number of preparatory steps. As a means for conversion between CMYK signal value and arbitrary chromaticity, a color material transfer amount which is a physical amount is handled as intermediate amount. A single color characteristic indicating a relation between the signal value and the color material transfer amount and a color mixing characteristic indicating a relation between each color material transfer amount (ink amount) of a plurality of inks and the chromaticity are obtained. By synthesizing the obtained single color characteristic and color mixing characteristic, the signal value/chromaticity characteristic is obtained in the form of a color conversion table.
