ANALYSIS OF ANILOX ROLL LINE SCREEN VALUE ON PRINT UNIFORMITY AND COLOR REPRODUCTION IN FLEXOGRAPHY

Abstract

Nowadays, flexography is one of the leading techniques in the graphic industry. It’s adaptability to different types of substrates is what sets flexography aside from other techniques. Since each of the techniques aims at providing higher print quality, it is necessary to control all the parameters which make influence on achieving the before mentioned. Anilox roll is used for getting as much uniform print in flexography. The three main characteristics of the anilox roll are: engraving angle, screen value and volume. The combination of these characteristics determines quantity and precision of color transfer onto the substrate. Examining the color transfer uniformity can be done using different methods; however, this paper focuses on analysis of mottling.
