Newsprint, also known as coated paper, is made by applying a layer of white paste to the base paper and calendaring it. The paper has smooth surface, high whiteness, uniform distribution of paper fibers, uniform thickness, small stretch ability, good elasticity, smooth surface, high whiteness, uniform distribution of paper fibers, uniform thickness, small stretch ability, good elasticity and water resistance. It has strong stretch ability and good absorption and reception of ink.
