Abstract: Based on GMG process, a test color target is designed to rapidly control digital proofing color. The uniform color space is selected as design basis of color test target, then GMG color control program is established. Afterwards, some studies on the correction principle and method about MX4 profile are carried out. Moreover, color data obtained before and after the correction is compared, including aberration, color gamut and tone. The results show that after correction, the various color index of sample is better than that before the correction, and the color target is available for proofing color's test and control. It is also found that the control method is simple and efficient, the acquired quality can reach the standardization, and the program is workable. On the other hand, this method can achieve stable proof quality, save the cost, improve efficiency. Therefore, it has application value for the rapid detection of digital proof color and the correction of partial aberration.
