Research on the Quality of Screen Printing Based on the UV Ink
Abstract:
With the development of the green inks, UV ink has been applicated wider and wider in the printing, packaging and the electronics industry. Based on the UV inks and screen printing process, this paper has investigated the influnce of mesh count, screen ruling, printing materials and ink viscosity on print quality by measuring the printing dot gain experimentally. The results show that the higher mesh count and more smooth printing material can induce the better dot, tone reproduction and higher printing precision. The more serious dot gain and the worse tone reproduction will induced by lower ink viscosity. The higher screen ruling cause the bigger dot gain value. Bigger rate of mesh count with screening ruling can reduce the moire phenomena.
