Offset paper scalability, absorption of ink uniformity, smoothness, tight texture, opacity, whiteness, water resistance is strong, should choose conjunctival offset printing ink and better quality printing ink. Ink viscosity should not be too high, otherwise there will be powder, hair phenomenon. But also to prevent the back sticky dirty, generally using dirty agent, powder or lining paper.
According to the ratio of pulp, rubber board paper is divided into special number, Number 1 and number 2 and Number 3, which has high strength and suitable printing performance. There are single-sided and double-sided points, and super pressing and ordinary pressing two grades. Offset printing is more advanced books printing paper, contrast, have higher demand to the expansion rate and the surface strength, acid and alkali should be close to neutral or weak alkaline, lest affect printing paper, glue scalability small, uniform on ink absorbency, good smoothness, texture closely opaque, good whiteness, strong water resistance, Conjunctival offset printing ink and better quality printing ink should be selected.

Ink viscosity should not be too high, otherwise there will be powder, hair phenomenon. But also to prevent the back sticky dirty, generally using dirty agent, powder or lining paper. Weight: 50,60,70,80,90,100,120,150,180 (g/m2)
