Surface sizing can improve the surface performances of paper. In this article we used surfacing sizing and ultra fine talcum powder to improve the quality of base paper. The results showed that the optimal formulation is: sodium hexametaphosphate 0.4 parts,PC-01 25 parts and 100 parts ultra fine talcum powder. The solids content of coating is 18%. Surface sizing and low solids coating can improve brightness,opacity, IGT Pick resistance, and breaking length which were improved by 3.4%, 6.5%, 2.07m/sec and 700m separately than uncoated paper respectively. K and N ink absorption value was reduced from 62.1 to 34.6. The method can be used to produce base paper for art paper and ultra low weight coated paper (ULWC). It can reduce the cost of art paper.
