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。

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,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,
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。
