Influence of substrate roughness on print quality parameters of digitally printed paper substrates

Abstract

In addition to printing techniques, there are various characteristics that
affect the quality of printed products. Most frequently questioned features
are line, dot, and text reproduction. In this paper it is investigated how
different substrates, printed by the same printing technique, affect the quality
parameters of printed samples. Print quality includes the process of obtaining
the desired reproductions of color and image elements, important parameters
of print quality are the quality of lines and dots, and the feature of the substrate
that is significant for this work is the roughness of the substrate. This paper
presents the testing of three different materials on to which the test form
was printed by electrophotography, as a digital printing technique. The tests
are based on analysis of line, dot and text reproduction, as well as analysis
of the roughness of the substrate on samples printed in black. Based on the
obtained results it can be concluded that the substrate affects the quality of
printed products.
