Claim Text:
1. An image processing apparatus that generates print data used by a printing unit capable of applying colored ink and clear ink to a print medium and performing a plurality of relative scans over a predetermined area of the print medium, so as to print an image, said apparatus comprising: a gamut converting unit configured to convert image data such that a color in a predetermined gamut is converted into a color in a print gamut which the printing unit is able to reproduce; and a print data generating unit configured to generate print data based on the image data converted by said gamut converting unit, wherein said print data generating unit generates respective print data for a first print mode and a second print mode which are different from each other wherein the clear ink is applied in the same relative scans as the colored ink in the first print mode, and (i) the clear ink is applied in the same relative scans as the color ink and (ii) the clear ink is applied in the relative scans after the relative scans in which the clear ink and the colored ink are applied in the second print mode, and said gamut converting unit is further configured to convert a color of a blue hue in the predetermined gamut into a first color in the print gamut when the first print mode is performed, and to convert the color of a blue hue in the predetermined gamut into a second color in the print gamut when the second print mode is performed, the second color having a different hue from that of the first color, the clear ink being applied in the first and second print modes such that the first color in the first print mode and the second color in the second print mode are perceived to be colors of the same hue.
