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.
