STUDIES ON THE IMPROVEMENT OF INK GLOSS AND INK SCUFFING OF MATTE PAPER
Specially designed and surface treated talc was used in this study as a coating color pigment to reduce the ink absorption and to increase the ink gloss. Matte paper was made and printed with solid color printing, after which ink gloss and ink scuffing were measured in laboratory, together with other paper properties. The mechanisms of talc in improving the ink gloss and ink scuffing were also discussed. The results showed that paper scuffing was closely related to roughness or smoothness. With the proper use of the talc in the coating color (e.g., 10ppt), roughness or smoothness can be improved, but with the improper use (e.g., 20ppt), they might be worsen. Increase the portion of talc in the coating color increase paper surface strength, but decreased air permeability, ink setoff and ink wet repellency. Paper gloss and ink gloss were decreased with the increase use of talc while the printing contrast was increased. Contrary to the paper scuffing, ink scuffing increased with the increasing use of talc. The phenomena were reasonably explained considering the hydrophobic and soft nature of talc, its platelike shape and its performance in coating color structure.
