The aim of this work is to compare the effect of
Ultraviolet (UV) flexo inks used in the paperboards coated with carboxymethyl cellulose
(CMC) and Polyvinyl alcohol (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 (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.
