Abstract
In a color image output apparatus for producing a color proof, even when target gradations corresponding to printing conditions (inks, sheets, and printing press conditions) to be simulated are changed, colorimetric values measured by a first colorimeter for correcting gradation correcting one-dimensional LUTs for the hues R, G, B are converted into desired colorimetric values to enable the color image output apparatus to output desired colors. For using a three-dimensional CM LUT generated by a second colorimeter in order to generate corrective values for the one-dimensional LUTs, there is provided a colorimetric value correcting table for converting output data from the first colorimeter into desired colorimetric values on the second colorimeter.
