Analysis of the flexo printed matte varnishing structure of polyester substrate

Abstract

Flexographic printing is one of the fastest-growing sectors in the printing industry. Our related research project examined the potential of matte varnishing as a surface finishing process. Various surface finishing processes, such as various safety varnishes, protective varnishes, barrier varnishes, and the types of matt varnish we have chosen, are playing an increasingly important role in the development of today's packaging material trend. In the course of the research, we tested the changes in the surface structure of the varnishing layer in the case of varying amounts of lacquer application, and we measured the gloss values in the case of the use of clichés with different surface patterns.
