The difference between coated paper and double offset paper in printing:

The raw materials of coated paper and the properties of coated paper. Coated paper is generally made of bleached chemical softwood pulp and the appropriate amount of bamboo pulp. When processing coated paper, the filling and sizing are heavier, and some high-grade coated papers need surface sizing and calendering. The coated paper uses the principle of water and ink balance when printing, so the paper needs to have good water resistance, dimensional stability and strength.

Coated paper is mostly used in color prints. In order to restore the color of the original manuscript with the ink, a certain degree of whiteness and smoothness is required. Coated paper is generally used for printing picture albums, color illustrations, trademarks, covers, ring linings, high-end books and books, etc. In recent years, due to the improvement of people's culture and living standards, books and materials have also developed to a higher level, and more and more books, periodicals, books, etc. are printed on copperplate paper.

Because the coated paper has the advantages of white quality, crispness, flatness and fineness, the text of the books and periodicals is clear, and the books and periodicals are flat and not easily deformed. Compared with the bald edition and newsprint books and periodicals, the grade is exceptionally different, which is deeply welcomed by readers and easy to use. The number of books and periodicals bound with coated paper will increase substantially in the future to meet market needs.
