交互正交设计在凹印水性油墨中的应用研究

目的研究交互正交设计在凹印水性油墨中的应用,以快速获得印刷品中所用水性油墨的最佳搭配配方。方法采用色差仪、目测等方法对9色凹印机印制的18种水性油墨印刷品进行外观质量评价,通过设计交互正交试验,并运用极差分析、方差分析等相结合的方法,对18种水性油墨印刷品的外观质量进行分析。结果 A2B1C1为最佳组合,印刷品的平均分值为91;通过分析银色色块得知,A2B1为最优组合,此时银色色块平均分值为41;分析红色色块得知,A1C2或A2C1组合较佳,平均分值分别为47和46;白墨与红墨,白墨与银墨之间在一定程度上存在复杂的交互作用。结论交互正交试验设计在凹印水性油墨配方中的运用是一种高效率、快速、经济的试验设计方法。

Application of Interactive Orthogonal Design in Gravure Water-based Ink

The work aims to study the application of interactive orthogonal design in gravure printing water-based ink in order to obtain the best formulation of water-based ink in printing products quickly. The appearance quality of 18 water-based ink printing products printed by 9 color gravure press was evaluated by chromatic aberration instrument and visual inspection. Through orthogonal experimental design and the combination of range analysis and variance analysis, the appearance quality of 18 water-based ink prints were analyzed. A2B1C1 was the best combination, and the average value of printed matter was 91. The analysis of silver color block showed that the combination of A2B1 was the best. At this time, the silver color block was 41. By the analysis of red color block, the combination of A1C2 and A2C1 was better, the average value was 47 and 46, respectively. In the process of analysis, there was a complex interaction between white ink and red ink, white ink and silver ink. Interactive orthogonal experimental design applied to gravure water-based ink is an efficient, fast and economical experiment.
