Research on the Performance Optimization of Silver Water-Based Gravure Ink

Abstract

At present, with the increasing requirements of environmental protection and the printing quality, the development of water-based gravure ink has become a trend. And silver ink has been favored by people deeply because of its excellent and exquisite packaging effect. So the development of silver water-based gravure ink has become an inevitable. Factors affecting the performance of ink such as types of silver pigments, pigment/binder ratio, type and dosage of dispersant, the type of film-forming resin were discussed. And the ink properties such as dispersion, gloss, surface tension etc. were studied and tested. Finally, we obtained formulation of the silver water-based gravure ink with good quality. The experimental results showed that the PHY20 aluminum pigment is the most suitable pigment with the minimum particle size that meeting the requirement of the gravure printing ink, and its best pigment/binder ratio is 2:3. The ink added dispersant JL115A with 2% owns the best dispersion property. When using the compound film-forming resins that 813: S2919 is 16: 9, the comprehensive performance of the ink is the best.
