水性色浆在铝箔表面凹印工艺过程研究

Process of Gravure Printing of Water-based Color Paste on the Surface of Aluminum Foil

目的研究一种已知的环保型水性色浆在凹印工艺参数不同的情况下,对印刷品涂覆均匀性能的影响。方法以自制水性色浆和铝箔纸为实验材料,研究该水性色浆在速度、压力、印版深度等参数不同情况下印刷品的性能,利用电子厚度测定仪等仪器表征了水性色浆在铝箔纸张上的涂覆性能。结果印刷压力和印刷速度均不同时,样品厚度的均值、极差及方差变化不大;样品厚度方差随着印版深度的增加而增加。印刷压力和印刷速度对印刷样品的厚度影响不大;印版深度对印刷样品的厚度有较大影响,且当印版深度为30μm时,样品厚度方差最小,水性色浆的涂敷均匀性最好。结论印版深度对纸基复合材料厚度有明显影响。

The work aims to study the effect of a known environment friendly water-based color paste on the coating uniformity of printed matter with different gravure process parameters. With homemade water-based color paste and aluminum foil paper as the experimental materials, the performance of printed matters was studied when the water-based color paste was at different speeds, pressures and plate depths. The coating effect of water-based color paste on the aluminum foil paper was characterized by such instruments as electronic thickness tester. When the printing pressure and speed were different, the change in mean value, range and variance of sample thickness was not significant. The sample thickness variance was increased with the increase in the plate depth. The printing pressure and speed had little effect on the thickness of printing samples, while the printing depth had a significant effect on the thickness of printing samples. Moreover, when the plate depth was 30 μm, the sample thickness variance was the minimum and the coating uniformity of water-based color paste was the best. The plate depth has a significant effect on the thickness of paper-based composites.
