Abstract: Restriction information on a total colorant amount for a medium is obtained. Patches at grid points in a color space corresponding to a plurality of colorants at which the total colorant amount falls within a restriction represented by the restriction information, and a patch at a point surrounded by the patches are generated. Color values are obtained by measuring the colors of the patches printed on the medium. It is determined based on a color prediction value between the grid points whether the measured color values are appropriate, and if so, a color value at a grid point at which the total colorant amount exceeds the restriction is estimated based on the measured color values. A color separation table is created based on the measured color values and the estimated value.

Abstract: A color separation table capable of performing both limitation of a color material applied in printing, and suppression of a false contour by smoothing processing satisfactorily is generated. Specifically, after generating the color separation table, smoothing processing is performed in order to obtain conformability between areas constituting the table. So as not to damage smoothness of lattice point data achieved by this smoothing processing, due to landing amount correction processing, landing amount correction is performed for an object lattice point and lattice points in a 3×3×3 range around it.
