ABSTRACT:
During the device link processing, an original lookup table LUT0is modified into a modified lookup table LUT1so that achromatic color value sets B2awill be associated with all the achromatic color value sets B1a. Accordingly, during a color conversion processing, by using the modified lookup table LUT1, any input achromatic color value set B1 in (0, 0, 0, K1 in ) will be converted into an output achromatic color value set B2 out (0, 0, 0, K2 out). In this way, the black-print image part in the input image that is reproduced by black ink only by printer A1will be maintained as a black-print image part and printed by a printer A2by black ink only. Thus, the black-print information of the input image can be maintained through the color conversion processing.
