Optimization of image screen printing process on film biodegradable packaging

Abstract

The article presents the research results of screen printing technological parameters to produce high-quality images on oxo-biodegradable film packaging. Printing parameters that influence the ink layer resistance to abrasion and the image resolution the most significantly have been set, analysing the experimental data. A direct linear correlation between the ink layer resistance to abrasion and the size of a technological clearance as well as between the image resolution and the lineature of a screen printing plate mesh has been shown. As a result of the study, mathematical models have been designed and the optimization of screen printing parameters has been made, providing high quality imprints with image high resolution, the ink layer of which is the most resistant to abrasion.
