Printing is a technique in which an original such as a character, a picture, or a photograph is transferred to a surface of a material such as paper, fabric, or leather by a process such as plate making, ink application, or pressurization, and the original content is copied in batches. There are many forms of printing, and the most common ones are traditional offset printing, screen printing and digital printing.

The letterpress paper uses the main paper for letterpress printing of books and magazines. It is suitable for texts such as important works, science and technology books, academic journals and textbooks for colleges and universities. The letterpress paper can be divided into four grades of No. 1, No. 2, No. 3 and No. 4 according to the distribution ratio of the paper materials. The number of papers represents the quality of the paper. The larger the number, the worse the paper quality.

Letterpress printing paper is mainly used for letterpress printing. The characteristics of this paper are similar to, but not identical to, newsprint. The paper structure of the relief paper is relatively uniform, and the gap between the fibers is filled with a certain amount of filler and rubber, and is also bleached, which forms a good adaptability of the paper to printing. Although its ink absorption is not as good as newsprint, it has the characteristics of uniform ink absorption; water resistance and whiteness of paper are better than newsprint.

The relief paper has uniform texture, no lint, slight elasticity, opacity, slight water resistance, and certain mechanical strength.
