關於畫冊印刷工廠的輸水系統

印刷工廠操作中對輸水系統要註意的問題如下

(1)印刷前要對自動循環供水系統進行檢查,保證水鬥進水、回水暢通,使水鬥里的潤版液保持恆定的液面高度,保證水輥正常均勻地供水。

(2)水輥間壓力調整適當,保證適當地、均勻地傳遞水分。

(3)要經常保持水輥、串水輥的清潔,水輥積墨上臟會影響到輸水的性能,發現上臟時要及時清洗。

(4)水輥絨套要經常刷洗和調換。

(5)為了保證印品的質量,印版上的水分應控制在最小限度。要保持水分小而不臟版,就需要勤觀察版面水分,因為車間內溫度和濕度、空氣流動情況、機器的印刷速度、水輥積墨等情況的變化,都會影響印版版面的水分大小,因此,在印刷中勤觀察版面水分是很重要的,版面水分的大小目前來講相當大部分的設備還是憑借操作者的經驗和感覺來測定的。

印刷時,借助外界光線觀察運轉中的印版,以版面水分的反光程序來辨別水分的大小,若版面看起來是烏黑的,沒有一點光亮,則水分很小;反之,若版面非常光亮,則水分過大;版面上水分適量時,看起來呈現灰暗色,稍微有亮光。
