印刷公司印刷時油墨粘版現象的原因是什麽

印刷公司著水輥與串水輥之間的壓力過大,造成油墨粘版現象。其原因是:膠印機在印刷時經常出現油墨粘版的故障,如果不經常擦版,油墨越堆越厚。

經檢查發現是著水輥與串水輥之間的壓力調得太大,從印刷中看到著水輥的絨布已被壓實,失去彈性,同時,著水輥旋轉時其水分被擠在著水輥與串水輥接觸的前面,使版面上得不到充分的水分,印版上粘油墨,造成臟版。

排除的方法:

調整著水輥與串水輥之間的壓力,調節時註意著水輥兩端偏心的旋轉方向應一致。

用0.3mm的鋼片插入著水輥與串水輥之間而後能夠稍有一定力度,拉出即可。兩頭和中間壓力要相同。

然後再校正一下著水輥與印版滾筒之間壓力(拉鋼片的手感略比前者稍重即可)。

最後再用壓水杠的辦法檢查壓力是否致,然後開機試印,印版上不再粘臟,表明故障排除。
