Abstract
A method of determining a set of color correction values includes generating a set of three gray mapper, or gamma, curves and determining from these curves the amount of color correction required to duplicate a sample set of color chips utilizing the particular inks and paper to be used in the final printing process. A set of correction percentages is generated from the correction determination for each of the colors of the set of color chips and these percentages are used in conjunction with input color values to generate corrected color values. The corrected color values may be modified to permit the variable substitution of black ink for a combination of the three colored inks or may be used to compensate for variations in hue of different black inks.
