It can be simply divided into industrial type, life type, cultural type, etc. These types are also the most useful. Among them, cultural paper also includes calligraphy paper, colored drawing paper, and packaging and printing paper. In packaging printing paper, according to the characteristics and differences of paper, it is subdivided into book paper, embossed printing paper, offset printing paper, coated paper, sketch paper, hand-painted paper, gift wrapping paper, newspaper, synthetic paper, etc. In addition, some high-end prints usually use this kind of painting paper.
Book and Periodical Paper: Newspaper is more widely used and less investment. Paper is mainly used for the printing of newspapers and magazines. The paper is soft, elastic and plastic, has good ink absorption capacity, and has a certain degree of toughness. It can be printed by most high-speed rotary presses. This kind of paper is made of wood pulp, so the paper is easy to yellow and absorb water.
Intaglio printing paper: Relief printing paper, the water absorption and color purity of the paper are slightly higher than that of book paper, and the ink absorption is even, but the strong ink performance is worse than that of book paper. Gravure printing paper, with high smoothness and water resistance, is mainly used for printing banknotes, stamps and other products that require high quality and are not easy to counterfeit.
Coated paper: It is a high-grade paper made by applying a layer of inorganic paint on the paper surface and then super calendering. The surface of the paper is smooth and feels good, with strong ink and high purity, which can better present the designer’s The unique sense of hierarchy also shows a sense of high-end. Therefore, coated paper is usually used for exquisite picture albums, commercial leaflets, etc.
Whiteboard paper: Whiteboard paper is a kind of special fiber structure synthesis. The surface layer of the paper has filler and rubber components and the surface is also coated with a layer of paint. It is a kind of paper produced by multi-roll calendering. The paper surface has high color purity. It has uniform ink absorption and high folding endurance. It is mainly used for gift packaging boxes, wall chart calendars, etc.
Synthetic paper: Synthetic paper is synthesized by using chemical raw materials and adding some additives, so it has unique softness, tensile strength, water resistance, temperature resistance, and can resist the corrosion of daily life without pollution and air permeability. Good, many places are used for packaging and printing of high-end artwork, high-end albums, books, etc.
