Abstract
Abstract A color conversion processing method which can apply an optimum color matching process to each color by selecting an appropriate color matching process for each color. Color image information includes at least one drawing object to be drawn by a color image outputting apparatus so as to output the color image information after conversion to the color image outputting apparatus. It is determined whether each color of the drawing object in the input color image information is a previously designated specific color. A previously designated color matching process is applied to the color of the drawing object only when the color of the drawing object is the specific color so that the color determined to be the specific color is not subjected to the color matching process.
