Abstract :The aim of this work is to compare the effect of Ultraviolet insert ignore into journalissuearticles values(UV); flexo inks used in the paperboards coated with carboxymethyl cellulose insert ignore into journalissuearticles values(CMC); and Polyvinyl alcohol insert ignore into journalissuearticles values(PVOH); on the printing quality. The study was made at two stages. At the first one, the surface sizing prepared using 5 % of carboxymethyl cellulose, 5 and 10 % of PVOH was coated on the surface of base paperboard and fully dried at the room temperature. The surface roughness, contact angles, cobb and gloss values of the coated base paperboard were measured. At the second stage, the test printings using both water based flexo ink and UV flexo ink on the coated base paperboard were carried out. The print density, L*a*b* and gloss values insert ignore into journalissuearticles values(printed); were evaluated on the printed surface areas in the coated base paperboards. The obtained results showed that the surface smoothness of the paperboards coated by PVOH was better than the one coated using CMC, but their resistance to wetting was smaller. The printing quality between the paperboards coated by PVOH or CMC was not significantly different. The print density, delta gloss and chroma values of printings attained using UV ink were higher compared to water based ink, revealing that the UV inks increased the printing quality.
