PURPOSE:To enable a hue and a density to be independently regulated, by a method wherein after converting a color signal of a first series to a plurality of color signals of an intermediate third series between the first series and a second series by a first conversion means and a linear sum thereof is taken, which is converted to a plurality of color signals of the second series by a second conversion means. CONSTITUTION:A color signal Si inputted to a color conversion device 8 is converted to an intermediate color signal Dij which is a color signal of a third series with a first conversion circuit 9. The obtained color signal Dij is inputted to an adder in the order of DjR, DjG, DjB, and their sum is successively stored in a latch 11 to obtain color signals Dj. Those color signals Dj are inputted to a second color conversion circuit 12 and are converted to ink amount signals Tj. Respective components Y, M, C, and K of the ink amount signals Tj are taken out serially and are separated with an alteration switch 16 to be supplied to an output unit such as a color printer or the like. Color conversion process is performed by a masking equation (4). Herein R, G, and B represents respectively a component of color, DY, DM, and DC representing the ink density of Y, M, and C, and M represents a 3X3 matrix coefficient. |
