Parameter optimization experiment for soft proofing

Abstract

Some experiments were designed to check the effects of monitor parameters such as color temperature, brightness, and gamma value on soft proofing. We have two illuminant levels D50 and D65, two brightness levels 100 and 120, and two gamma value levels 1.8 and 2.2 to be chosen in constructing international color consortium profiles (ICC profiles). Then, soft proofing simulation experiment was executed. Comparisons were made between the results of soft proofing and printer to obtain the optimum parameters. Results were evaluated by color difference analysis, individual component analysis of ΔL*,Δa*, and Δb* values, and psychophysical experiments. Experiments show that the performance of soft proofing varies a lot with different parameters. And it can get a better performance with the appropriate parameters. At last, the optimal parameter combination was obtained.
