In a color conversion definition process, first, a profile of a virtual device having a color reproduction range that well simulates a color reproduction range of a printing system is produced. A first color conversion is then defined so as to convert a coordinate point in a color reproduction range of a printer expressed in a first RGB color space to a coordinate point in the color reproduction range of the virtual device expressed in a second RGB color space dependent on the virtual device. A second color conversion is then defined so as to convert a coordinate point in the color reproduction range of the virtual device expressed in the second RGB color space to a coordinate point in the color reproduction range of the printing system expressed in the CMYK color space. The resultant coordinate point represents a color very similar to a color represented by the printing system.
