目的 研究涂布纸水性柔版印刷过程中关键参数对印刷效果的影响。方法 改变涂布纸水性柔版印刷中的关键过程参数，并结合统计学分析技术研究其对印刷效果的影响。结果 网纹辊加网线数对涂布纸印刷品的密度、色差、印刷光泽度、颜色明度、墨层耐磨性的影响很大；网纹辊压力、印刷压力和印刷速度在一定范围内对涂布纸印刷品的实地密度、色差、印刷光泽度、明度、墨层耐磨性的影响并不显著。结论 在涂布纸柔性版水基油墨印刷过程中，正确选用网纹辊线数是获得高质量印品的关键。

The work aims to study the effects of key parameters on the printing quality during flexographic water-based ink printing of coated papers. By changing the key process parameters during flexographic water-based ink printing of coated papers and combined with statistical analysis methods, their effects on the printing effect were studied. The screen density of anilox roll had very important effect on the quality indexes of the printed coated papers, such as density, color difference, printing gloss, color brightness and the abrasion resistance of ink layer. However, the pressure of anilox roller, printing pressure and printing speed, to some extent, had little effects on the above-mentioned quality indexes. Correct selection of screen density of anilox roller is critical to obtain printed coated papers with high printing quality during flexographic water-based ink printing of coated papers.
