Copy paper printing is a kind of paper for cultural industry that is very difficult to produce. The technical characteristics of the product are mainly as follows: high physical strength, excellent uniformity and transparency, and good appearance properties, fine, smooth and smooth , No bubble sand, good printability. Generally, the production of printing paper is divided into two basic processes: pulp and papermaking. Pulp is the use of mechanical methods, chemical methods or a combination of the two methods to dissociate plant fiber raw materials into natural pulp or bleached pulp. Papermaking is the process of combining pulp fibers suspended in water into paper sheets that meet various requirements through various processes.
Copy paper printing uses letterpress printing. When ink is applied to a raised surface and a piece of paper is used to cover the ink-coated surface, the ink is transferred to the paper. The printing method that uses this principle is called letterpress printing. The rubber stamp is a tool for embossing using letterpress printing, which transfers the ink from the raised surface to the copy paper.
copy paper printing uses thermal transfer printing, which is a special type of indirect transfer printing and an emerging printing process. Modern thermal transfer printing must first use special inks, and in some cases, special papers. The pattern is usually printed on paper by gravure printing. The paper can use special heat-resistant printing paper and coated paper.
