The method includes creating: a first table defining conversion relationship from a signal of a first standard color to which limitation of a total amount of ink is not applied into a signal of a second standard color to which the limitation is applied; a second table defining conversion relationship from the signal of the second standard color into a first expansion color signal to which the limitation is applied; a third table defining conversion relationship from a color signal in a device-independent color space corresponding to the signal of the second standard color into a color signal in a device-dependent color space; and a fourth table (color profile) defining conversion relationship from a color signal in the device-independent color space corresponding to the signal of the second standard color into a second expansion color signal in the device-dependent color space by the third and second tables.
