QUALITY CONTROL OF PRINTED PRODUCTS BY IMAGE ANALYSIS AND PROCESSING

Abstract

Controlling reproduction of printed products imply colour and gloss measurement, as well as evaluation of secondary print quality parameters (reproduction of text and lines, sharpness, uniformity etc.). In the last decade it was shown that the vast majority of quality attributes in printing could be controlled by image analysis and processing. In this article we summarise image processing methods for evaluating quality parameters in printing and finishing, with the focus on the possible drawbacks and industrial solutions.
