Evaluation Structure and Algorithm for Printing Color Quality

Three-level evaluation structure for color quality is established.The first level is to evaluate each color of each ink zone;the second level is to evaluate the color quality of each ink zone;and the third level is to evaluate the color quality of the whole image.The evaluation algorithm for each level is studied.The evaluation of the first level uses the fuzzy hierarchy comprehensive evaluation method,the relative importance of each factor is determined by the grey relevancy method,then the weight of each factor is determined by the analytic hierarchy process,and the evaluation result is finally determined by the max membership method.The evaluation of the second level uses the integration of the weighted arithmetic average method and fuzzy comprehensive evaluation method.The evaluation of the third level uses the weighted arithmetic average method.The example indicates that the evaluation structure and the algorithm can objectively and correctly evaluate the printing color quality.
