Coated Paper: A High-quality Substrate for Exquisite Printed Products

Coated paper, also known as coated printing paper, is a high-grade printing paper made by coating base paper with white coating. The following is a detailed introduction to coated paper:

1. Main raw material:

- Coated base paper and coating. The base paper is required to be uniform in thickness, small in elasticity, high in strength, and good in water resistance. The paper surface is not allowed to have paper defects such as spots, wrinkles, and holes; the coating is composed of high-quality white pigments (such as kaolin, barium sulfate, etc.), adhesives (such as polyvinyl alcohol, casein, etc.) and auxiliary additives.

2. Production process:

- First, the white coating is applied thinly and evenly on the base paper through a coating machine, and then dried, rolled into a roll on a paper reel, and then sent to a super calender for calendering and finishing, and finally cut, select paper, and pack.

3. Classification method:

- Classification by coating : There are single-sided coated paper and double-sided coated paper.

- Classification by gloss: There are glossy coated paper, cloth-textured coated paper, etc.

- Classification by quality : It can be divided into three grades: A, B, and C.

4. Performance characteristics:

Surface characteristics: The paper is uniform and tight, with high whiteness (more than 85%), smooth and glossy, and the coating is firm and consistent, which is convenient for obtaining exquisite and clear patterns and texts after printing.

Printing adaptability : It has good ink absorption and reception, and is suitable for various printing methods such as offset, letterpress, gravure, and flexographic printing. The pressure should not be too large during printing, and the printing speed and ink viscosity should be controlled.

5. Application fields :

It is widely used in the covers and illustrations of books and periodicals, color pictures, various exquisite product advertisements, samples, product packaging, trademarks, etc.

6. Size and package

The gram weight range is 80g-300g, and the size and packaging can be customized. The packaging is generally divided into rolls, separate packages, and piece packages.

In summary, coated paper, as an important printing material, has unique characteristics and a wide range of applications. When selecting and using coated paper, it is necessary to make comprehensive considerations based on specific printing requirements and paper characteristics to ensure the best printing effect.
