| 目的 研究瓦楞纸箱后印工艺产生 “排骨纹” 故障的有效控制方法。方法 使用IGT F1柔印印刷适性仪和全功能光泽度计， 实验研究了印刷密度与光泽度随印刷压力变化的特性， 以及压力设置与实际所承受压力的关系； 采用有限元模拟方法模拟了印刷过程中单元瓦楞范围内面纸的压力分布规律。结果在印刷压力增大到125 N左右之前， 印刷密度随着印刷压力的增加而迅速变大， 当印刷压力增大到250N左右之后印刷密度则趋于稳定； 光泽度基本不受印刷压力的影响； 压强测量值与所施加的印刷压力基本呈线性关系； 同时， 在单元瓦楞范围内的压力分布曲线中， 楞谷部分的压力低于楞峰部分的压力。结论 人眼所察觉到的 “排骨纹” 是由印品密度变化导致的， 与印品光泽度的变化无关， 印品密度的变化则主要是由印刷压力的变化造成的。 |

| Objective To study the effective method of controlling the phenomenon of strips on corrugated board in the process of post-printing. Methods The variation characteristics of print density and gloss under different pressure values and the relationship between the measured pressure value and the set printing force were experimentally studied using IGT F1 and gloss meter. The press distribution over single flute width on corrugated boards in the printing process was simulated using finite element simulation method. Results The print density rapidly increased with the printing force until the printing force reached about 125 N, and reached a plateau when the printing force reached about 250 N, but the print gloss was not affected by the printing press. The measured pressure value was linear with the set printing force. And the pressure on the peak of flute was bigger than that on the valley of flute in the pressure distribution curve. Conclusion The strips were caused by the variation of print density instead of print gloss. And the variation of print density was mainly caused by the variation of the printing pressure. |
