Abstract
According to the present invention, if an image is printed on both sides of a printing medium, the possibility of rubbing ink off from the printing medium is minimized to inhibit contamination of the printing medium and the interior of the printing apparatus, while maintaining the print grade of the image. Thus, if a double side print mode is executed in which an image is printed on both sides of the printing medium, then, for a particular image part, a ratio of an amount of black pigment ink used to an amount of black dye ink used is set so as to limit the amount of black pigment ink used and to compensate for a decrease in print density with the limited amount of the black pigment ink used.
