印刷廠如何做到套印準確

在實際生產中,會經常印刷細網目、高質量的印品。怎樣才能使這種印品達到更為理想的套準呢?除了要求具有精湛的製版技術、質地優良的紙張、油墨和色數相宜的條件外,作為膠印機操作者,還必須註意下列幾個方面。



(1)選取較低的印刷速度這是因為低速印刷會減少和降低由於紙張和機器所造成的套準誤差。主要應從機器的穩定性,紙張的交接準確性,以及減少紙張的彈跳等方面去分析、探討。



(2)選用色數相宜的印刷機經驗證明,根據印張的色數去合理地選擇比較適宜的機型,是達到準確套印的必要手段。那麽,究竟怎樣根據所印色數來選擇機型呢?一般來說應當考慮下述兩個主要原則。


①續紙次數要盡量地少些。最理想的狀況應當是一次續紙,因為一次性的續紙就可以不考慮續紙套準對於印刷套準的影響。


②印張在機組之間的傳遞次數也要盡量減少,這是因為紙張的傳遞次數越多,它的總套準誤差就會越大。頻繁的紙張傳遞對於紙張的平整質量也有顯著的影響。
