Research on Applying Fuzzy Theory into Printer Quality Evaluation

摘要

From printing technology's perspective, printing quality is determined by the comprehensive effects of all the printing product appearance features. The factors which dominate to comprehensive effects of all the printing product appearance features include definition of image, tone rendering, color rendering, uneven, and gloss, etc. In the print quality evaluation, this factor is affected by many other factors. Therefore, printing quality evaluations are indeterminate. Most of printing quality evaluations belongs to fuzzy theory, which brings a lot of troubles to the printing quality evaluation. The paper mainly research that the synthesis decision-making method in fuzzy mathematics theory is used to tone reproduction of printing quality, and analyze the feasibility of applying Fuzzy Synthetic Evaluation Model in printing quality evaluation. The synthesis decision-making method is used to determine the tone indicator system of printing, establish Fuzzy Evaluation Mode, and analyze the influencing factors. Through the evaluation of numerous experts, the weight will be offered for the specified factors. On the basis of weights, printing quality can be evaluated by determining the membership function of all the factors and calculating the score through fuzzy algorithm. The paper studies have shown that the synthesis decision-making method in fuzzy mathematics theory can be used to solve the printer quality evaluation problem and is valid for evaluating the results in actual application.
