印刷廠處理PS版上不同部位的臟污的方法

處理PS版上不同部位的臟污,方法有以下幾種。


①如果有多餘的擋光物出現在印版實地部位,由於底片的實地部位本來就完全不透光,所以並不影響曬版質量。


②如果多餘的擋光物出現在網點部位,或者墨實地,線條和空白部位的交界上,就會在這些地方留下臟污。如果用除臟劑去除,就不可避免地把圖文也除掉,所以只能用刮刀細心地修刮,效果自然不好。臟污嚴重的話,印版只能報廢。量國


③如果臟點出現在空白部位,並且離圖文部位有一段距離,則可以通過塗除臟劑的方法去除


所以,曬版曝光前,要特別仔細地檢查膠片網點部位,以及圖文和空白交界的地方,保證不出現臟污。手工拼版時,要保證小張底片的邊緣和粘貼的膠紙不出現在這個部位。
