印刷廠的印刷機裝版的形式有哪幾種

就一般膠印印刷機而言,印版的裝夾形式主要有下述兩種

(1)固定式裝夾採用這種裝夾方式的印版版夾,被固定在印版滾筒的空當里,不能夠取下。換版時,只能單獨取下舊的印版,並將新的印版裝夾上去,它的卸版與裝版必須在機器上進行。由於結構比較簡單,國產膠印機多採用此種方式。


(2)套入式裝夾採用這種裝版方式的版夾是活動的,它可以從印版滾筒的空當里取下。把要裝夾的新版,在機器外邊緊緊地裝版夾上,然後再一起裝到滾筒上去。這種操作,可以節約一部分裝版工時。在裝卸印版時,應註意下述問題。

①應當防止印版和其他東西相碰撞。在移動和貯放時,特別要避免印版產生馬蹄印。

②上版前,務必將印版滾筒錶面擦洗乾凈,如發現油墨和其他污垢乾結於版面時,應用鋼片刮掉、擦凈。切不可留下鋼片劃傷的痕跡。

③上版時,應將上、下、來、去等位置,盡量裝得準確,要差得太多,否則將會造成校版困難,延長校版時間。

④印版的版夾螺絲必須擰緊,防止在印刷過程中,因螺絲松脫使印版掉下而造成事故。版夾螺絲既不要過松,也不能過緊,鋁版不伸長、網點不變形為準

⑤印版下襯紙要清潔平整,紙張厚度的誤差量要小,不應當有皺紋和撕裂現象。

⑥裝版步驟與順序:按舊版劃線做記號→測量新裝印版厚度算好襯紙厚度)→印版插入版夾並加入襯紙→初步對準規線並將滾筒轉到另一端→印版另一端插入版夾→復核規線並全面拉準印版。
