基于模糊灰关联的纸张印刷适性评价模型

目的以市场上存在的各种品牌的纸张作为分析对象,获得最佳样品,选择最优纸张。方法评价方法的实施过程包括两部分,参照ISO 12647印刷标准,选取实地密度、印刷光泽度、网点扩大率为50%、相对反差率为75%、实地叠印率等5个参数进行测试,利用模糊评价的方式对参数进行无量纲化处理。结果通过灰关联计算关联度,在此基础以上结合主观评价,确定5个参数权重分别为2.3,0.5,1.7,0.8,2,根据计算综合数据得分的结果进行排序,获取最优样本。结论该方法提高了印刷质量,降低了生产成本。

Analysis of Paper Evaluation Model Based on Fuzzy Grey Relation

The work aims to obtain the best sample and select the best paper with all kinds of paper in market as analysis objectives. The evaluation methods consisted of two parts. Firstly, according to the ISO 12647 standard for printing, five parameters including solid density, printing gloss, 50% dot gain, 75% relative contrast value and printing overprint rate were tested. The parameters were subsequently nondimensionalized by fuzzy evaluation method. The weight of the five parameters were 2.3, 0.5, 1.7, 0.8 and 2 respectively with the theory of grey relation degree combined with subjective evaluation. The optimal sample was obtained according to results of the calculated data. In conclusion, this method can improve quality and reduce production costs.
