PIGMENTS INFLUENCE ON COATED PAPER SURFACE AND PRINT QUALITY

Abstract

Coating the paper surface is an important process that improves the image and printability of the paper. The particle size, and type of pigments used for the coating cause changes in the mechanical and surface properties of paper. In this study, two different clay were used as pigment. Latex is used as a binder. Coating color prepared with a mixture of latex and pigment was applied to the paper surface with K-Control Coating type apparatus. Coatings are applied as 10 g / m2 single face. For this study, the effect of coating in coating color with different pigments on paper surface resistance and paper resistances is aimed. Resistance properties of the papers were examined as a result of the coatings. In addition, water resistance and Dennison wax tests were determined for the printability effect. Printing was done on sample papers using Cyan ink in the IGT test device under laboratory conditions.
The results showed that the tensile strength, tearing, were improved as the type of pigment and the coating amount were increased. The printing properties of sample papers have improved.
