The Study on the Influence of Monomer on the Printing Quality of UV Waterless Offset Ink

摘要

In order to observe the influence of monomer on the printing quality of UV waterless offset ink, ink samples with different monomer were made, and the main performance parameters such as viscosity, thixotropy, yield value, fluidity and stickiness were tested. Proofing by printability tester, and the printing qualities such as solid density, gloss, dot gain and print contrast were tested. Analyzing the influence of the difference of ink performance that caused by monomer on the printing quality of UV waterless ink. The results show that ink performances affect the printing quality directly. The differences of monomer's structure and functionality have great effect on ink's performance such as viscosity, thixotropy, yield value, fluidity and stickiness, and it can lead to the difference of printing quality such as solid density, gloss, dot gain, and print contrast.
