application fields also have different classification habits. Taking the United States as an example, it is divided into commercial printing, periodical printing, book printing, News printing, form printing and miscellaneous printing. Commercial printing can be divided into six categories: commercial magazines and periodicals, trademark paper and packaging paper, product samples and purchase orders, commercial advertisements, parts and financial and legal prints. China is generally divided into News printing, publishing printing (including books and magazines), packaging and decoration printing, Securities printing, stationery printing and parts printing. In Hong Kong, it is customary to divide into News printing, bulk printing, other printing (including typesetting, photographic plate making, binding, paper cutting, etc.) and carton printing

since the 1960s, the two printing branches of internal printing and rapid printing in international enterprises have developed rapidly. The internal printing equipment of the enterprise is mainly light and small, also known as light printing. It mainly provides printing services for the enterprise, which can enhance the confidentiality and timeliness of the internal data of the enterprise. With the development of computer technology, the internal printing equipment of enterprises is becoming more and more computerized. Rapid printing was originally differentiated from commercial printing plants. With the development of industry and Commerce and the needs of accelerating information exchange, the rapid printing industry has grown rapidly. Its business scope has been expanded to photographic reproduction, offset printing, typesetting, electrostatic copying, color copying, and even word computer processing, laser printing, inkjet printing, etc. The popularization of microprocessor has a great impact on the development of rapid printing industry

generally, it can be divided into four categories: relief printing, intaglio printing, lithography and hole printing. The graphic part of the printing plate used in relief printing is raised, including engraving, movable type plate, type plate, copper zinc plate, photosensitive resin plate and flexographic printing. Due to the great development of flexographic printing since 1980s, its printing machine structure and printing substrate are different from general embossing, so some countries regard flexographic printing as an independent printing type. The graphic part of the gravure printing plate is concave, which is divided into engraving gravure, photographic gravure and electronic gravure. The graphic part and non graphic part of the lithographic printing plate are basically in the same plane, which usually refers to offset printing, but in fact, lithography (basically eliminated) and offset printing (preserved as a unique process) also belong to the category of lithography. Hole plate printing is mainly screen printing, that is, it is made of screen, and the graphic part can be printed through ink rather than the ink impermeable printing plate of graphic part. Transcription plate mimeograph is also a kind of hole plate printing
according to the printing procedure, the above four printing methods are different from direct printing and indirect printing. The layout ink is first transferred to the blanket cylinder, and then the pictures and texts are transferred to the paper by the blanket cylinder. Offset printing is indirect printing, and other printing methods (including lithography in lithography) are direct printing. The image and text of the direct printing plate is the reverse image, and the image and text of the indirect printing plate is the positive image
although the above printing methods are different from the printing process, when printing, the paper (or other substrate) contacts the printing plate and applies a certain pressure, which belongs to contact embossing printing. With the development of computer technology and equipment, laser printing and inkjet printing appear. This new method has no embossing action during printing, which is called non-contact or non-pressure printing.

printing is mainly divided into four types: relief printing, gravure printing, lithographic printing and hole printing.

watermark, color printing, pad printing, silk screen printing, iron printing

printing types:
I. classify the printing methods according to the relative position of the graphic and non graphic areas on the printing plate
according to the relative position of the graphic and non graphic areas on the printing plate, the common printing methods can be divided into four categories: relief printing, gravure printing, lithography and hole printing:
(1) relief printing, The graphic part of the printing plate is convex, which is significantly higher than the blank part. The printing principle is similar to the seal. The early woodblock printing, movable type printing and later type printing belong to relief printing
(2) gravure printing. The graphic part of the printing plate is lower than the blank part. It is often used for the printing of banknotes, stamps and other securities
(3) in lithography, the graphic part and blank part of the printing plate are almost in the same plane, and the printing method is based on the principle of oil-water immiscibility
(4) hole plate printing. The graphic part of the printing plate is holes, and the ink is transferred to the surface of the substrate through the holes. Common hole plate printing includes hollow plate and screen plate
2. Classify the printing methods according to the paper feeding method of the printing machine
according to the paper feeding method used by the printing machine, printing can be divided into:
flat paper printing: also known as sheet fed printing. It is printed on flat paper
Web Printing: also known as rotary printing. It is a method of using web printing
III. classification of printing methods a
ccording to whether the printing plate is in contact with the substrate
according to whether the printing plate is in direct contact with the substrate, printing can be divided into:
direct printing: printing ink on the printing plate is in direct contact with the substrate. Such as relief printing, gravure printing and screen printing
indirect printing: a printing method in which the ink of the printing plate is transferred to the substrate through blanket
IV. classify the printing methods according to whether the printing plate is used or not.
according to whether the printing plate is used or not, printing can be divided into:
plate printing: the printing plate is printed on the substrate with a pre prepared printing plate. Such as relief printing, gravure printing and screen printing
plateless printing: a method in which the printing plate is printed directly on the substrate through a computer-driven print head (or print head). Such as digital printing
v. classification of printing methods according to the printing principle
according to the printing principle, that is, according to the principle that the printed part and the non printed part of the printing plate produce printed matter in the printing process, it can be divided into physical printing and chemical printing
1. In Physical printing, the printing ink is completely a kind of accumulation and bearing in the image part, while the non image part is concave or convex, which is different from the height of the image part and cannot be stained with the printing ink, leaving it blank. Therefore, the transfer of the printing ink in the image part to the printed material is only a physical mechanical action. Generally, relief printing, intaglio printing, hole printing, dry lithography, etc. are physical printing (the printing surface is higher or lower than the non printing surface)
2. In chemical printing, the non inking of the non image part (non printing surface) of the printing plate is not caused by the low concave, convex or blocked part, but by the chemical action to produce a film that absorbs water and repels ink. Of course, it is still a physical phenomenon that the image part (printing surface) absorbs ink and repels water, the non image part absorbs water and repels ink, and the water and grease backwash each other. However, during the printing process, the non image part must be continuously supplemented with a film that absorbs water and repels ink, so it is chemical printing. Offset printing is of this kind. For offset printing, glue substances should be added to the water tank solution to supply the mucus layer of carboxyl groups from source to source, so as to keep the non printing surface of the printing plate from being infected by grease
VI. classification of printing methods according to the number of printing colors
according to the number of printing colors, there can be the following distinctions:
1 Monochrome printing: it is not limited to black. It is applicable to those who display images in one color. Poly color printing is divided into three types: case method, register method and multi color method
for the color enhancement method, add another color within the double line range in the monochrome image to make it clear and bright, so as to facilitate reading. The printing of general children’s books is mostly used; In the chromatic method, the colors are independent, do not overlap each other, and there is no other color to make the edge line of the range, which is successively overprinted on the printed material. The printing of general line table, commodity packaging paper and terrain is mostly used
2. Color printing: that is, multi-color printing. According to the additive color mixing process, the natural color original is decomposed into the primary color separation plate, and then the primary color plate is reprinted on the same printed material by using the color mixing process. The natural color printing of bishop’s original is also obtained due to the different overlapping area of primary colors. All color prints, except for a small number of additive and chromatic methods, are printed by multicolor method
four color printing mainly adopts the printing method. The four color inks of CMYK (i.e. cyan, magenta, yellow and black) are transferred to the printing materials for color formation, which can reproduce various colors of the original through different proportions of these four colors. In order to expand the color space, more than four colors (such as six color printing) are also used. The packaging industry often adopts the method of four colors plus one or more spot colors to ensure that users are satisfied with the color and increase the anti-counterfeiting characteristics of printed materials
VII. Classification of printing methods according to the use of printed materials
classification according to the use of printed materials, such as book printing, newspaper printing, advertising printing, banknote printing, map printing, stationery printing, special printing, etc
books and magazines were printed by letterpress in the past. More gradually switch to lithography. 2. Press printing used to be printed by relief rotary machine, which is fast and has a large printing volume. In recent years, in order to meet the needs of color, lithography or photographic intaglio rotary printing is used
advertising printing, including color pictures, pictorials, posters, etc., mostly adopts lithographic printing, sometimes with relief, intaglio or hole printing
the printing of banknotes, bonds and other securities is mainly gravure printing, supplemented by letterpress and lithography
