PROBLEM TO BE SOLVED: To appropriately print a special color out of a range that a printing device can express, by a color with a high approximation degree. SOLUTION: A program makes a computer perform color matching processing, and then makes the computer execute input color acquisition processing for printing data and color conversion processing which converts an input color to an output color which is expressed by mixing ratios of every colors in CMYK (Cyan, Magenta, Yellow and blacK) ink used in the printing device by means of an ICC profile for output 20 according to color reproductivity of the printing device. The input color acquisition processing at least acquires the special color which is a color out of usual colors prepared as colors which can be expressed by the CMYK ink as the input color. The ICC profile for output 20 has a normal color conversion part 22 for converting the normal color to the output color, and a special color conversion part 24 for converting the special color to the output color, and the color conversion processing converts the special color to the output color using the normal color conversion part 22.
