ANALYSIS OF THE QUALITY OF FEATURES PROVIDED BY THE ELECTROGRAFIC PROCESS AT THE GRAPHIC SYSTEM KONICA MINOLTA C6000L

Abstract

The paper presents research in the field of digital technique of press-electrography. For printing, the Konica Minolta C6000L graphic system was used. For the purposes of this research, a test card was created, which was printed on three substrates of different grammes of 150 g/m², 200 g/m² and 300 g/m², followed by white and yellow paper measurements, optical densities, increase in tonal values, Lab values i spectral field reflection on the test map. The results of the work are shown using graphics, followed by analyzing and comparing the results obtained. The aim of the study is to calculate the color difference, whose analysis later determined the quality of the repeatability of the printing. Also, an analysis of time and spatial repeatability was performed.
