Photoshop分色設置中提供瞭如何對CMYK四色版的產生進行控制,包括:黑版產生( Black Generation)的方法、底色去除UCR( Under Color Removal)、印刷總墨量控制( Total Ink Limit)及底色增益UCA( Under Color Addition)

①在分色設置對話框中
,可根據需要及印刷廠的生產質量選擇分色類型 UCR/GCR,由於技術因,GCR常會造成高光部分有臟點,UCR只是對暗調部分的替,不會有太大的偏差,使用比較多。

②黑版產生的程度有
Light(輕度)Medium(中度)Heavy(高度)Maxium(最大) Custom(定義)等幾種選擇,自定義是可以在圖像中任意調節黑版曲線,他色版會自動計算出自身的替代量。

③黑版墨量限制是指UCRGCR中黑版所用油墨量限制, Photoshop中默認設置是100%,通常將其設置為80%~90%就基本上能夠壓住其他顏色。


④總墨量限
製表示印刷機所能支持的最大油墨密度, Photoshop中默認設置是300%


⑤底色增益
UCA( Undercolor Addition)是指採用GCR黑版
產生方式後,在圖像的暗調區域再增加一定量的青、品紅、黃,如果在暗調區域只用黑版代替,有時會造成過於平淡的調子,適當地加入黃、品紅、青彩色油墨,會使圖像暗部更加豐富。另外,只有在選擇CR黑版產生方式時,才可調節此選項。UCA可以調節的範圍0~100%,隨著數值的增加,CMY的量逐漸增大。
