Patent ID: 8773723

Claim:
A color processing apparatus for generating a color separation table for an image forming apparatus which has a relatively dark color material with a high relative density and a relatively light color material with a low relative density, the color processing apparatus comprising: a setting section configured to set a gamut boundary for limiting use of the relatively dark color material; a determiner configured to select one of a plurality of relatively dark color materials, and determine, from a basic color separation table, at least a grid point which satisfies a condition that a color material value of the selected relatively dark color material is nonzero and a color value to be reproduced based on color material values set to the grid point exists in a region brighter than the gamut boundary; and a replacement section configured to replace, by a color material value of the relatively light color material, the color material value of the selected relatively dark color material set to the grid point which satisfies the condition.
