为了更好地控制柔性版印刷中的印刷压力,通过在压力中心区安装一个薄的电阻应变压力传感器,对印刷过程中压力进行了测量。在此基础上建立了柔性版印刷的压力计算模型,进而得出了柔性版印刷中最佳印刷质量所需的最大印刷压力。最后通过实验分析了最大印刷压力与软、硬质印版特性的关系,从而为柔性版印刷过程中软、硬质印版选用不同的印刷压力提供参考。

In order to better control the flexographic printing pressure, the pressure in the printing process was measured by installation of a thin pressure sensor in central area of the pressure. The pressure calculation model in flexographic printing was established based on the measurement and the required maximum printing pressure for the best flexographic printing quality was obtained. The relation between the maximum printing pressure and the hardness of printing plate was analyzed through experiments. The purpose was to provide reference for printing pressure selection for printing plate of different hardness.
