Patent ID: 7852511

Claim:
A color processing apparatus for generating a color separation table used for converting image signals into signals of color materials used in a printing apparatus, said color separation table storing grid point data as amounts of color materials represented by the color material signals correspondingly to grid points defined in a color space of the image signals, said apparatus comprising: a table data obtaining unit configured to obtain the grid point data corresponding to the grid points of the color separation table; a correction unit configured to perform a correcting process for the grid point data so as to reduce the amount of color material represented by the obtained grid point data; a smoothing unit configured to perform a smoothing process for the grid point data that have been subjected to the correcting process by said correction unit; and a determining unit configured to determine whether the amount of color material represented by the grid point data that have been subjected to the smoothing process exceeds a threshold value on a landing amount of the color material to a print medium, and to determine whether to make said correction unit perform the correcting process repeatedly so that the amount of color material represented by the grid point data that have been subjected to the smoothing process does not exceed the threshold value when the amount of color material represented by the grid point data that have been subjected to the smoothing process is determined to exceed the threshold value.
