Paper coating processing can obtain high paper gloss and printing gloss. By adjusting the ratio of pigments, the particle size of pigments, the amount of adhesive, and controlling the coating amount and drying temperature of paint, the change trend of paper gloss and printing gloss under different conditions was analyzed. The results show that the paper gloss and printing gloss increase with the increase of the amount of CHINA clay, and decrease with the increase of the GCC amount; the increase of the adhesive amount increases the paper gloss and the printing gloss increases obviously; the paper gloss And printing gloss increases with the increase of coating weight. Regression analysis of the data shows that the ratio of china clay to GCC (90% of particle size <2μm) is 1:1, the amount of adhesive is 12%, and the coating amount can be obtained very well when the coating amount is 16g·m-2. Excellent paper gloss and printing gloss.
