柔版印刷油墨有溶劑類、醇類、水性類三種。印刷塑料等非吸收性承印材料時,一般選用溶劑型油,


印品通過油墨中溶劑的揮發而乾燥。對於不同的承印基材,應選用不同的油墨。在生產中,為了調節油墨的黏度和揮發速度,


常要加入一定量錶面張力較低的溶劑,以降低整個油墨體系的錶面張力,從而提高塑料薄膜的潤濕性。


為瞭解決墨層附著牢度和油墨的揮發速度之間的矛盾,可以在稀釋劑或油墨中加入相應於該種油墨的樹脂(橡膠)


或其柔性版是使用帶有彈性的合成橡膠或光固樹脂做版材的基料。為利於印刷,應選用最適宜的溶劑。


如天然橡膠版材選用醇類、縮醇類、二辛酯類溶劑;聚酯橡膠選用石油系醇、烷烴、一辛酯類溶劑;丁基橡膠選用醇類、酮類、酯類溶劑等。。。
