高速印刷状态下,保持良好的套印精度,是衡量印刷机性能的重要标准。针对高速状态下滚筒(或辊子)径向跳动量迅速增大引起的套印精度的问题,从卫星式柔性版印刷机结构及印刷工艺过程入手,分析径向跳动对实际印刷位置的影响,建立径向跳动影响套印精度的分析模型。在此基础上,推导出径向跳动对套印精度的影响因子,直观地反映滚筒(或辊子)尺寸、径向跳动量和套印精度的关系。通过印刷试验和径向跳动测试,验证了径向跳动影响套印精度分析模型。

Under the state of high-speed printing, maintaining a good overprint accuracy is an important performance of the press. For the problem of overprint accuracy caused by the rapidly increasing radial runout of the cylinder ( or roller ) in the high-speed printing state, based on the structure and printing process of satellite-based flexographic press, this paper analyzes the effect of radial runout on the actual print position, an analysis model of overprint accuracy influenced by radial runout is established. By the model, the factor of overprint accuracy caused by radial runout is deduced, which could directly reflect the relationship of the size of cylinder ( or roller) , radial runout and overprint accuracy. The model of overprint accuracy influenced by radial runout is verified by printing experiment and the test of radial runout.
