Abstract

A method for processing color image data converts input RGB color data to output CMY color data. An input device is calibrated to a intermediate color space, and an output device is calibrated to the intermediate color space. The input RGB color data is collected from the input device, and is converted to intermediate color space data. The intermediate color space data is converted to the output CMY color data, and is outputted to the output device. During the conversion process, the image data is processed to compensate for gamut mismatch.
