基于网点的喷墨印刷质量评价体系研究

目的在构建调频网点微观立体模型的基础上,通过提取微观参数并结合印品宏观质量评价指标,建立基于网点的3阶段印品质量模糊综合评价体系。方法基于3层递阶准则机制,体系第1阶段采用模糊层次法评价各区域的各颜色质量;第2阶段利用模糊综合评判法,对各区域四色喷墨质量进行综合评价;第3阶段根据加权算术平均算法,对喷墨样张进行总体质量评价。结果该质量评价体系全面考虑了影响喷墨印刷品质量的微观与宏观因素及其关联度,客观确定不同影响因子的权重,反映了质量评价的等级。经验证,评价结果与主观相一致。结论该质量评价体系计算步骤明确,评价结果清晰,系统性强,为喷墨印刷品的质量评价提供了参考。

Evaluation System for Inkjet Printing Quality Based on Micro-dot

Based on the construction of FM micro-dot model, the inkjet printing quality system of 3 levels was established by extracting the micro-parameters with the combination of macro quality indexes for prints. Based on the 3-layer hierarchical criterion mechanism, the first level of the system evaluated the printing quality of every single color using fuzzy AHP; the second level of the system evaluated the quality of four colors in each region by fuzzy comprehensive evaluation method; the third level evaluated the overall quality of the ink jet proof by weighted arithmetic average algorithm. The system fully considered the micro and macro factors which had impacts on the printing quality as well as their correlation. Besides, it determined the weight of different parameters objectively and deduced the quality evaluation scale accurately. The verification showed that the evaluation was consistent with the subjective result. In conclusion, this quality evaluation system had strict theoretical structure with specific calculation steps. The evaluation results were clear and highly systematic. It offers a new method for inkjet printing quality evaluation.
