During the process of digitized duplication, in order to reproduce and reappear the color of the color image manuscript, a closed-loop color correction method with the application object of color image duplication system, composed of a scanner and a color ink-jet printer is proposed, which is based on the colorimetric characterization theory and applies the model of polynomial regression. Compound and unitied calibration is achieve by correcting tristimulus values of image pictures when it is being scanned and printed. Accuracy of color restoration is improved effectively by circulating approximation. Theoretical analysis and experimental results show that after color correction by the method, the maximum color difference between the final copy and the original copy is reduced from 48.51ΔE*ab to 7.90ΔE*ab, and the average color difference is reduced from 15.91ΔE*ab to 2.69ΔE*ab. Thus it achieves accurate reproduction and reappearance of color.
