PS版使用过程中常见故障及解决方法

Common Troubles Occurred in Using PS Plates and Countermeasures

PS版是目前印刷行业制作印版最简便的方法,可以在曝光显影后直接制成印版,使用时先用紫外光对PS版上的感光树脂层进行曝光,再用碱性显影液将已曝光的树脂层腐蚀掉形成印版,即可上机进行印刷。PS版的使用过程也是一项精巧的工艺过程,使用不当会严重影响印刷质量,本文根据多年市场技术服务经验,归纳总结了其常见故障的现象、产生的原因和排除这些故障的方法。

PS plates are the most commode method widely used in the printing industry for making printing plates. They can directly yield finished printing plates ready for printing after exposing and processing. The PS plates are exposed with ultra-violet radiation, then processed with alkaline developer, which corrodes the exposed resin coating layer thus forming the printing plate. This process is also a delicate technology affecting seriously the printing quality when not properly run. This paper presents a summary of common troubles encountered during the use of PS plates, their appearances, causes and countermeasures.
