印刷廠​對平凸組合印刷的工藝要點【步殼印刷】

印刷廠平凸組合印刷的工藝要點【步殼印刷】


1)從產品的設計開始,最好能考慮到膠印和凸印的套印位置能拉開,留有一定的空間,扣套多些,嚴套少些,以防止膠印和凸印之間的套印不準

2)製版時,對膠印和凸印結合嚴套的產品,一般以印色為基礎,將凸印版墨稿根據圖案位置貼到膠印的底片上,當產生新的底片時,再將凸印部分挖掉去做凸印版,這種方法稱為膠凸組合工藝的拼挖法

3)對膠印和凸印結合的部分,在深淺顏色反差較大的前提下,深色印版可採取吃一線的方法,防止紙張收縮所造成的套印不準

4)印刷順序應採用先膠印後凸印的方法,凸印版面大多是實地,如果先進行凸印,盡管油墨經滾筒壓力後部分連接料滲透到紙張中,但仍有少量的顆粒留在錶面,經後工序膠印後整個版面受壓剩離,降低了油墨的吸附牢度,從而影響產品的質量另外,膠印中使用的酸性潤版液會降低印刷品錶面的光澤度,尤其是印金、銀油墨的產品。如果先膠印,由於是網點成像,呈色墨量小,且凸版印刷為局部版面受壓,對產品的質量影響較小

5)膠印是圓壓圓的印刷方式,而凸印多是圓壓平的印刷印產品圖文相同的情況下,膠印圖文有所擴大(印版伸長造成的),因此,只有改變兩種印刷方式在所方式,包襯,才能達到套印準確的要求。改變襯墊的最好辦法是:把橡皮滾筒上的包襯轉移到印飯滾筒上,可以縮短印刷圖文的長度,增減量基本相同。但必須嚴格控制在一定範圍內,否則會對印版的耐印力及網點變形等產生不良的影響
