ABSTRACT:
The present invention selects color materials for a virtual device from real color materials, adjusts a gray balance to obtain a predetermined black color at a maximum device value by using selected color materials, assigns a color material amount to each device value so that a relation between the device value and brightness becomes linear when outputting gray, and evaluates a color range reproducible by the virtual device with the assigned color material amount by an inclusion rate for a standard color group so as to start the process all over again from selection of the color materials if evaluation is poor. It thus obtains the color reproduction definition of the virtual device and performs the color conversion including gamut mapping using the color reproduction definition.
