Colorimetric data of a tone patch of a specific color is transmitted from a specific-color-data extracting unit to a hue characteristic calculator, to obtain a hue characteristic of the colorimetric data. A replacement data generator generates replacement data by performing hue correction for reflecting the hue characteristic with respect to second gamut data corresponding to the specific color. A specific-color-data replacing unit replaces the second gamut data corresponding to the specific color with the replacement data, and color target data after such a replacement process is gamut compressed from the second gamut to third gamut by a gamut compressing unit.
