Comparison of prints made with conventional and UV inks

Abstract

Quality of the offset prints made with conventional and UV curable inks was compared. Color characteristics of cyan, magenta, yellow and key – color bar patches were measured in CIE L*a*b*space at illuminants D50 and D65 and compared. Statistical analysis showed also the differences in the color printing stability. It was found that type of the ink influences friction properties of the prints and it was shown that prints made with UV inks exhibit higher static and kinetic friction coefficient as compared with prints made with conventional inks.
