Abstract:
1. A color profile creating apparatus including first gamut data having a first gamut, second gamut data obtained by compressing the first gamut data to a second gamut, and colorimetric data of a tone patch of a specific color output by a color-image output device having a third gamut, the color profile creating apparatus comprising: a storage unit that stores the first gamut data including at least one entry including a flag designating the specific color; a gamut compressing unit that compresses the second gamut data to the third gamut; a hue-characteristic obtaining unit that obtains a hue characteristic of the colorimetric data for the specific color based on the flag; a replacement data generator that generates replacement data for the second gamut data, on which a tone characteristic of the second gamut data and the hue characteristic obtained by the hue-characteristic obtaining unit are reflected, based on the second gamut data corresponding to the first gamut data of the specific color; a data replacing unit that replaces the second gamut data corresponding to the first gamut data of the specific color with the replacement data generated by the replacement data generator, prior to a gamut compression by the gamut compressing unit; and a color-profile creating unit that creates a color profile for the color-image output device based on color data after the gamut compression by the gamut compressing unit and the first gamut data.
