Abstract
The present invention readily produces an image of a special color separation, with respect to a color image which is to be reproduced by a plurality of color separations including Y, M, and C separations. The method first specifies a relationship between a predetermined density of a special color separation and densities of a plurality of other color separations corresponding to the predetermined density of the special color separation; then extracts each color element included in a color image as a target color element; and determines a density of the special color separation according to the specified relationship.
