| 摘要: |
| 目的 研究影响胶印图像质量各因素中的纸张与油墨各项性能对胶印图像饱和度、光泽度、耐磨性等所起作用大小的情况。方法 使用 2 种油墨对 3 种牛皮纸进行胶版印刷（简称胶印），采用偏最小二乘法（PLS）分析纸张平滑度、光泽度、表面孔隙情况、油墨粘度、颗粒大小等因素对所得图像色彩饱和度、光泽度以及墨层的耐磨性的影响情况。结果 纸张光泽度和表面平均孔径大小对印刷图像质量的影响作用较大，对纸张平滑度和孔隙相对深度的影响作用较小，对油墨各项性能的影响作用最小；胶印图像的饱和度、光泽度以及耐磨性（饱和度变化）与纸张平滑度、孔隙相对深度以及光泽度的相关性较大，而与其他影响因素的相关性相对较小。结论 在胶印过程中，改善纸张的光泽度、平滑度，或者适当调节纸张表面平均孔径和孔隙相对深度，可以在很大程度上提高图像的质量。 |

| Abstract: |
| The work aims to study the role of each performance of paper and printing ink (among the factors that affect the quality of offset image) in the saturation, gloss and abrasion resistance, etc. 2 kinds of inks were used for the offset printing of 3 types of kraft paper. Then, partial least square (PLS) was used to analyze the effects of smoothness, gloss, surface pore and ink viscosity of the paper and the particle size, etc. on the color saturation and gloss of the image and the friction resistance of ink layer. The results showed that the paper gloss and surface average aperture had significant impact on the offset image quality, had small impact on the smoothness and relative aperture depth of the paper, and had the least impact on the performances of the ink. The correlation between saturation, gloss and friction resistance tion change) of the offset image and smoothness, pore relative depth and gloss of the paper was large; while the correlation with other influence factors was relatively small. In conclusion, in the process of offset printing, the improvement of gloss and smoothness of the paper and the proper adjustment to surface average aperture and pore relative depth of the paper can improve the image quality largely. |
