Assessment of the print quality parameters’ impact on the high-quality flexographic print visual experience

Abstract

Over the years, computing and information technology in the printing industry has been brought to a very high level. However, the models for assessing and estimating quality by considering print quality parameters are still being researched. This paper presents a mathematical model that was used for the purpose of enabling assessment of the flexographic print quality based on the visual experience of a standard observer. The model facilitates the assessment of print quality parameters’ impact on the visual experience of the high-quality flexographic print. As a part of this assessment process, print quality measurement analysis of each ink (cyan, magenta, yellow and black) was performed by focusing on several print quality parameters; dot gain at 50%, trapping, mottling, optical density and colour gamut. The use of logistic regression analysis in this paper allowed for a definition of nine variables that significantly impact the subjective perception of the total print quality. Methodology presented in this paper can be effectively applied in the scientific and professional practice of graphic design.
