Material characteristics of Coated Paper

A coated paper used for copperplate printing. According to different uses, it can be divided into single-sided or double-sided coating. There are flat paper and web paper. The quantitative is generally 70 ~ 150g / m2, and the double-sided coating is also 180 ~ 250G / m2. The paper is uniform and compact, with high whiteness (more than 85%), smooth surface, high gloss and firm and consistent coating, which is convenient to obtain exquisite and clear patterns and words after printing. Coated base paper is made from bleached chemical wood pulp or partially bleached chemical straw pulp on a paper machine.

It is mainly used for red wine labels, picture books, color illustrations, book covers and advertising trademarks.

Coated paper is characterized by very smooth and flat paper surface, high smoothness and good gloss. Because the whiteness of the coating used is more than 90%, and the particles are very fine, and they are calendered by the super calender, the smoothness of coated paper is generally 600 ~ 1000s. At the same time, the coating is evenly distributed on the paper surface and shows pleasant white. It is required to have high coating strength, The coating is thin and uniform without bubbles, and the amount of adhesive in the coating is appropriate to prevent the paper from powder and hair during printing. In addition, the absorption of coated paper to xylene shall be appropriate and can be suitable for fine mesh printing of more than 60 lines / cm.
