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.

A method of converting input color data to output color data comprising the steps of: calibrating in a first calibration an input device to an intermediate color space; calibrating in a second calibration an output device to said intermediate color space; collecting said input color data from said input device; converting said input color data to intermediate color space data in accordance with said first calibration; outputting said color data to said output device; wherein said converting of said intermediate color space data to said output color data includes processing said intermediate color space data for matching an input gamut to an output gamut for said output device, and wherein said intermediate color space is a uniform color space; said processing includes identifying at least one unprintable device independent color output value which, when converted to a device dependent color output value, cannot be represented by said output device, and determining an adjusted device dependent color output value for representing said device independent color output value which is within said output gamut; said adjusted device dependent color output value being determined within said intermediate color space; said adjusted device dependent color value being determined as the shortest vector distance within said intermediate color space between said unprintable color output value and a color output value which is printable by said output device.
