Technical terms about printing industry

Printing is one of the four great inventions in ancient China. From ancient times to the present, the printing industry needs very professional technology. With advanced printing equipment, the threshold of the printing industry seems to be lowered. However, the printing industry is a low-threshold and high-tech industry. If you want to do well, you still need to work hard, which is a complex and systematic project.
Printing can be divided into four categories: plane printing, screen printing, flexographic printing and gravure printing.

Graphic printing: We usually see pictures, posters, floor books, etc., which are printed by offset and PS plates and film.
Screen printing: printing plate in the form of screen cloth with mesh size ranging from 80 mesh to 500 mesh. The printing quality is directly related to the quality of mesh plate making.
Flexographic printing and gravure printing: they are mainly used for printing plastic products. At present, these two methods are mainly used to make plate for plastic printing in the market. Whether the plate is excellent or not directly affects the printing quality. Example stereotype is a relatively fine one-plate making method.
Of course, with the development of high-tech era, digital printing, that is, digital business printing (CTP), is in the ascendant in China. It is fast, simple and convenient to use digital printing for less than 500 sheets without film making, which meets the immediate needs of modern business.

Film: The film used in printing and plate making is called film. You can use the film to dry the PS version to get on the machine, just like when it is used as the negative film of a photo. It is an essential process in precision printing.
Generosity: size 889×1194mm. Size of each base paper Orthogonality: size 787×1092mm. Size of each base paper Film coating: A film is coated on the surface of printed products to protect the quality of printed products and also play a moisture-proof function, which can be divided into bright film and dumb film.
Overoiling: Coat the surface of printed matter with an oil film to protect the color of printed matter from breaking.
UV: It is printed with special effects and layering. It can be divided into partial UV and total UV Coding: print more than 7 bits of variable data, and some need to build a database. Divided into sequential codes and random codes.
Die-cutting: Processing printed products into the required shapes.
