Influence of substrate thickness on the quality attributes of polymer materials reverse printed by screen printing technique

Abstract

The printing substrate and its characteristics have a significant impact on print quality. Print quality includes desired colour reproduction and satisfactory reproduction of image elements. This study analyzes the transparent polymer material substrates, printed by a screen printing technique. The paper primary focus is on the analysis of colour differences between obverse and reverse side of the printing substrate, and in addition, on line quality and the dot roundness analysis. Considering the results, it can be concluded that substrate thickness has influence on the colour reproduction in reverse printing when observing through a transparent substrate. Also, the differences between line area and perimeter in obverse and line area and perimeter - in the reverse printed side increases with the printing substrate thickness increase and dot roundness observed from the reverse side has a more irregular shape.
