Study on the Printability of Chemical and Physical Foaming Inks

Abstract

Foaming inks have a wide range of applications in the light industry, mainly including chemical foaming inks and physical foaming inks. The chemical foaming ink was obtained by chemical reaction of a chemical foaming agent to form gas, and the physical foaming ink was obtained by vaporizing the liquid core material in the microcapsule at a certain temperature to generate internal pressure. In this paper, chemical foaming agents and physical foaming microcapsules were used as functional materials. The corresponding foaming ink was obtained by formula design. Meanwhile, the chemical and physical foaming inks were printed by screen, flexo and gravure printing processes, and the printing law was systematically studied. The print abilities of products, including foam height, color and ink adhesion were mainly investigated by different printing methods. The ultimate aim was to provide practical guidance for the foaming ink in the application process of lightweight technology.
