Coated paper is also called printed coated paper. The surface of the base paper is coated with a layer of white paint, and the base paper is made of super calendering. It is divided into single-sided paper and double-sided paper, and the paper surface is divided into light splitting and cloth grain. The paper has smooth surface, high whiteness, good ink absorption and ink adhesion. It is mainly used for offset printing and gravure printing of fine screen printing, such as illustrations in advanced picture books, calendars and books. The disadvantage is that the powder is easy to stick and fall off after being wet, so it can't be stored for a long time. There are usually copy shops.
