The uses and differences between coated paper and coated cards in printing paper

The characteristics of coated paper are that the surface of the paper is very smooth and smooth, with high smoothness and good gloss. Because the whiteness of the paint used is more than 90%, and the particles are extremely fine, and it is calendered by a super calender, the smoothness of the coated paper is generally 600~1000s. At the same time, the paint is evenly distributed on the paper surface and shows a pleasing white color. The requirement for coated paper is that the coating is thin and uniform, without bubbles, and the amount of adhesive in the coating is appropriate to prevent the paper from powdering and linting during the printing process.
