Abstract
The output response of an image processing system having a color printer and a color printer characterization is linearized by printing a target image having target patches of differing color densities. After measuring printed patches, a calibration transform is generated that incorporates the relationship between requested and measured color densities. The calibration transform is then composed with the characterization, calibrating the printer characterization.
