ABSTRACT:
Three primary color signals derived from an original color picture are processed to produce six or seven signals indicative of six or seven hues. These six or seven signals are then modified or corrected by a plurality of correction factors so as to produce three color picture signals which may be used for producing three driving signals respectively applied to three ink-jet print heads via which three primary color inks are applied to a print sheet. The correction factors may be manually adjusted so as to achieve accurate color reproduction by optimally controlling the amount of inks to be applied on the surface of the print sheet. In addition to the primary color inks a black ink may also be used where the amount of the black ink may also be controlled by using other correction factors. The present invention is applicable to not only an ink-jet color reproducing system but also to color printing systems of other types.
