Difference kinds of paper
Newsprint: newsprint is mainly used for the printing of newspapers and some relief books and periodicals. The paper is soft, elastic-plastic, ink-absorbing and suitable for various high-speed Rotary Printing. This kind of paper is mostly made from wood pulp, contains more lignin and impurities, the paper is easy to yellowing and crispness, water resistance is very poor, it is not suitable for long-term preservation, relief printing paper: This is a special paper used for relief printing, the nature of paper is similar to newsprint, water resistance, color purity, paper surface smoothness is slightly better than newsprint, ink absorption is more uniform, but strong ink ability is worse than newsprint. OFFSET PRINTING PAPER: Offset Printing paper is used for offset (lithography) printing paper, and divided into single-sided offset paper and offset paper two sides, single-sided offset paper is mainly used for printing posters, packaging boxes, etc.
The double-sided offset paper is mainly used for printing picture books, pictures and so on. Offset paper is compact, small flexibility, strong water resistance, can effectively prevent polychromatic overprinter when the paper deformation, dislocation, pulling, peeling and other problems. Can give printed matter to maintain a better purity of color. Offset coated paper: also known as coated paper, is coated with a layer of inorganic paint on the paper surface by super calendering made of a high-grade paper, paper smooth surface, high color purity, printing can be a more fine and clean dot, can better reproduce the original level of feeling, widely used in art pictures, picture albums, commercial leaflets and so on.
INTAGLIO PRINTING PAPER: INTAGLIO printing paper white firm, with good smoothness and water resistance, mainly used for printing notes, stamps and other high-quality and not easy to copy the printing. White Board paper: White Board paper is a kind of paper made by multi-roller calendering, which has a uniform fiber structure, a filler and a glue on the surface and a coating on the surface, has a more uniform ink absorption, has a good folding, mainly used in commodity packaging boxes, commodity table lining, picture wall chart, etc. .
Synthetic paper: Synthetic paper is made from chemical raw materials such as alkenes and some additives, with soft texture, strong tensile strength, high water resistance, light and heat resistance, and can resist the corrosion of chemical substances, no environmental pollution, good air permeability, widely used in the printing of high-grade artwork, maps, picture books, high-grade books and periodicals, etc. .
