黑色實地印刷為什麽採用K100C400的疊印方式

​我們曾經碰到這樣的案例:印刷四色書刊封面,封一為正常四色產品,封底是滿版黑,封底在印刷時發現顏色不實,如果加大墨量的話,又造成封一顏色偏悶。分析這一現象的原因是,採用四色印刷工藝時,為了保證階調和色彩的正確還原,每一色的墨層厚度都應嚴格控制。

我們曾經碰到這樣的案例:印刷四色書刊封面,封一為正常四色產品,封底是滿版黑,封底在印刷時發現顏色不實,如果加大墨量的話,又造成封一顏色偏悶。分析這一現象的原因是,採用四色印刷工藝時,為了保證階調和色彩的正確還原,每一色的墨層厚度都應嚴格控制。

通常在四色印刷中,黑色的實地密度不超過1.8,以這樣的密度印刷大面積黑色實地,會缺乏厚實的視覺效果。

如果在黑色實地色塊上疊印少量青色,從色相上看還是黑色,視覺效果卻會更加厚實。例如:在白紙上只印一色黑時,由於印刷過程中紙毛、紙粉在橡皮布上堆積,或由於其他原因影響到油墨的轉移,會使黑色實地上出現白色砂眼,黑白對比非常顯眼。

如果黑實地上疊印了青色平網,即使黑色實地上有微少的砂眼,由於露出的不再是白色的紙基,而是青色的網點,相對於黑白對比來說,黑青對比就不那麽顯眼了,可以使黑底色看起來更加均勻美觀。

因此,在印前設計中常用的方法是在大面積黑色實地部分疊印40%左右的青色。
