凹版印刷Mark线在线检测系统的研究

The research of the online testing system Mark line of intaglio printing

文章在分析Mark线在线检测系统工作原理的基础上 ,着重论述了Mark线在线检测系统的实现方案及其设计电路。该检测系统电路简单、可靠 ,并能保证凹版印刷机在线速度为 12 0米 /分钟的高速工作条件下 ,各色相对基准色套色偏差的控制不超过± 0 .2mm。

On the basis of analysis of the online working principle of testing system of the Mark line, the paper emphatically discussed the realization scheme of the online testing system of the Mark line and its design circuit. Tttis circuit of the testing system is simple and reliable and can guarantee that when the online speed of gravure press works with high speed of 120 metre / minute , the control of the chromatography deviation of the relative standard colour of all kinds does not exceed ±0.2 turn.
