Influence of different varnishes on the abrasion resistance of water-based flexographic prints
Marta Gajadhur , Agnieszka Chrzanowska
AbstractThe presentation will be concerned with analysis of the impact of different water-based varnishes on the abrasion resistance in flexographic printing with water-based inks. Print rub-off tests were performed for 3 different water-based varnishes used in flexographic printing. Tests were performed on Ink Rub Tester under identical rub rate (100 cycles/min) and with different methods. The rub-off resistance was evaluated by spectrophotometric and visual observations. About 60000 rub-off cycles were performed. The ΔEab* parameter was used in evaluation. Research on the quality of water-based inks and varnishes may contribute to popularization of these environmentally friendly products in flexographic printing. Since water is the major component of these products, they are environmentally friendly, inexpensive, non-flammable, work friendly etc.
