A fuzzy decision model for color reproduction

Color quality appraisal refers to a visual evaluation of an original color image and an assessment of the degree to which that image is matched in photomechanical or electronic reproduction. The evaluation of reproduction quality is quite subjective since it relies on the individual judgments of color technicians who have different perceptions of color and its component qualities. To reduce the amount of rework due to subjective evaluation of color reproduction, an objective model is proposed here. In this model, a fuzzy set of quality factors is introduced and a numerical quality value calculated. This measure is then compared with an acceptable quality value experimentally established for particular customers and printing processes. Finally, the installed model is tested in actual production, and compared with the conventional evaluation method in a cost analysis.
