ABSTRACT:
A color printer having three color filters is provided with a filter controller which controls the insertion time of the color filters to print a particular color such as a flesh color of a human figure into a preferable particular color of preferable color balance and density. The filter controller includes an arithmetic memory circuit which memorizes for three primary colors a relation between the color density of the particular color in the color original and the preferable insertion time of the color filters to print the particular color into the preferable particular color on the color paper.
