關於深圳印刷廠里GCR工藝及應用

為了更好地滿足多色高速印刷機生產效率的發揮,尤其是大批量的輪轉商業印刷、報紙印刷的需求,催生了印刷廠GCR工藝的研究與問世。

GCR到底是什麽?

1)GCR定義GCR是 Gray Component Replacement的簡稱,中文翻譯成灰成分替代,是指將原稿中從亮調到暗調的復色中三原色疊印的灰成分全部去除,用增加黑版墨量的方法來補償,也稱為“兩色加黑”工藝。將三原色等量的部分全部去除,並用增加適量的黑墨來替代去除的部分。

2)GCR有何特點

GCR特點:

①灰成分替代工藝以黑版為主,三原色版為輔;

②黑版為真正的全階調版,即網點從0~100%都有;

③灰成分的替代範圍是全階調的;

④最大限度地減少墨量,墨層乾燥迅速,有利於多色高速印刷;

⑤黑墨代替彩墨,油墨成本大大降低。
