What is the printability of ink?
Ink (ink, printing) is an important material used in printing. It prints the patterns and characters on the substrate by printing. The ink consists of major and auxiliary components, which are evenly mixed and rolled repeatedly to form a viscous, gelatinous fluid. It consists of binder (resin), pigments, fillers, additives and solvents. For books, packaging, decoration, building decoration and electronic circuits, plates and other printing. With the increase of social demand, the variety and output of ink also expanded and increased correspondingly.
Printability is impact characteristics in the whole printing stroke in viscosity, yield value, thixotropy, consistency and tensile force of static or quasi-static.
Flat printing technology is the most commonly used offset printing, offset printing ink color detection mainly its properties (such as color and luster), tinting strength, rheological properties (including viscosity, fineness and dry adhesion, thixotropy, ink and other technical indicators). According to the habit of the ink industry and the calibration unit of the testing instrument, the ink performance in this paper adopts centimeter gram second unit system.
