Study On Printability of Plastic Water-based Gravure Ink

摘要

Plastic water-based gravure primary inks were prepared. The primary inks were diluted with resin solution which had good compatibility with primary inks. Isopropanol was added to improve the printability of the ink. Effects of pigment/binder ratio、 dispersant、 resin solution and isopropanol on printability of the inks were analyzed. The results showed that the pigment/binder ratio was 2:1, the content of dispersant of 750 was 0.7%, the content of dispersant of 760 was 0.7%, the formulation of mixed resin was 3808:1437:2640=1:O:1, the content of isopropanol was 1%, printability of inks both on PET and BOPP was good.
