What are the printing methods?

Question 1: What are the engraving printing techniques in Sui and Tang Dynasties in China? Northern Song Dynasty (Bi Sheng)-movable type printing ingot; Yuan () wheel typesetting disk; Modern (Wang Xuan)-laser phototypesetting printing.

Question 2: There were several printing technologies in ancient China, such as block printing and movable type printing. In modern times, they were classified according to printing forms: relief printing, lithography, gravure printing, flexographic printing and screen printing.

According to the printing principle, it is divided into pressure printing, pressureless printing, thermal transfer printing, holographic printing and others.

Question 3: What kinds of printing are there? Generally, it can be divided into four categories: relief printing, gravure printing, lithography and stencil printing. The graphic part of the printing plate used in relief printing is convex, including block printing, movable type printing, lead printing, copper-zinc printing, photosensitive resin printing and flexographic printing. Flexographic printing has developed greatly since 1980s, and its printing machine structure and printing substrate are different from general relief printing, so some countries regard flexographic printing as an independent printing category. The graphic part of gravure printing plate is concave, which can be divided into engraving gravure printing, photographic gravure printing and electronic engraving gravure printing. The graphic and non-graphic parts of lithographic printing plate are basically on the same plane, which usually refers to offset printing, but in fact lithographic printing (which has been basically eliminated) and Kelashan (preserved as a unique process) also belong to the category of lithographic printing. Stencil printing is mainly screen printing, that is, a printing plate made of screen, in which the graphic part can pass through ink, but the graphic part cannot pass through ink. Copying mimeograph is also a kind of stencil printing.

According to the printing procedure, the above four printing methods are different from direct printing and indirect printing. Offset printing is indirect printing, and all other printing methods (including lithography in lithography) are direct printing. The graphics and text of the direct printing plate are reverse images, and the graphics and text of the indirect printing plate are positive images.

Although the above printing method is different from the printing process, when printing, the paper (or other substrate) contacts the printing plate and exerts certain pressure, which belongs to contact embossing. With the development of computer technology and equipment, laser printing and inkjet printing have appeared. These new methods are called non-contact or pressureless printing because they have no impression in the printing process.

Question 4: When did printing start? 1. The origin of block printing was between 590 and 640 AD, that is, from Sui Dynasty to early Tang Dynasty. Printed materials were unearthed in the early Tang Dynasty.

Shen Kuo said in Meng Qian Bi Tan that block printing was not popular in the Tang Dynasty. During the Five Dynasties, most Confucian books were printed, and Feng Dao began to print the Five Classics. The classics in the future are all printed.

2. A.D./KOLOC-0/04/KOLOC-0/~/KOLOC-0/048, Bi Sheng in Cloth, made movable type printing with clay characters.

Question 5: What are the types and characteristics of commonly used printing materials? There are many printing methods, different methods, different operations, and different printing effects. Traditional printing methods can be divided into four categories: relief printing, lithography, gravure printing and stencil printing. Letterpress printing is called letterpress printing, the printing surface is prominent and the non-image part is concave. Letterpress printing includes two types: letterpress printing and rubber printing. Movable type printing letterpress printing is developed from early clay type, woodcut type and lead casting type. In modern times, most of them are typesetting. At the same time, this printing method is a kind of direct printing, because it is printed directly on paper through a printing plate. Printing plates used in letterpress printing, except movable type typesetting, such as special fonts, patterns, pictures, etc., are all made into zinc plates (commonly known as electric plates) by photographic plate-making method, and recently developed into nylon offset printing plates to improve the effect of dot printing. Generally, the relief printing plate is flat, but in some cases, it is necessary to copy the flat plate into a curved plate, which can be mounted on a drum rotary gravure press for batch printing, such as newspapers. Besides printing pictures and characters, letterpress printing can also add some accessories, and it can also print characters and patterns on the concave-convex printing surface, cut the printing surface (commonly known as beer sample), print paper-tearing pinholes, and print automatically indexed digital characters. Flexgraphy flexographic printing is similar to relief printing, but the difference is that the printing plate is a piece of soft glue, just like the image glue used for stamping. The ink used is similar to gravure printing, with high volatility and thinness, and is used for printing adhesive tapes and plastic bags. The method of plate making is divided into three steps: first, the pictures and texts are made into letterpress. Secondly, the hard rubber similar to bakelite is heated and pressed on the electric plate to print the hard printing plate female die. Thirdly, another kind of soft rubber is heated and pressed on female die and female die to make the same offset printing plate as the original in the first step. All kinds of gummed paper, such as fiber paper, P, V and C gummed paper, polyester gummed paper, cellulose acetate paper, etc. Can be printed on materials with no ink absorption and permeability on the surface. Suitable for printing plastic bags, hand-painted and large and small plastic packages. But this printing method can't print fine dots and lines like offset printing and relief printing, so the picture should pay attention to the great effect. The basic principle of lithography is named after the development of early lithography. The early lithograph printing was first polished with stones and then printed, and then improved into zinc metal plate or aluminum plate, but the principle remained unchanged. There is no difference between the printed part and the non-printed part, which is flat. Based on the principle that water and oil are immiscible, the printed part retains an oily oil film, while the layout on the non-printed part can absorb appropriate moisture. Suppose that after printing ink on the layout, the printing part repels the water-absorbing ink, and the non-printing part absorbs water to form ink resistance. The method of printing in this way is called lithography. Lithographic printing developed from early lithographs, because of its unique characteristics in plate making and printing, its work is extremely simple and its cost is extremely low, so it has been continuously studied and improved by experts in modern times and has become the most used method in printing today. Lithography Lithography is developed from the early lithography transfer method. It is depicted on a transfer paper, then falls on a plate to become a negative pattern, and then is printed on paper as a positive pattern. Due to the pressure that this method is subjected to during printing, the originally flat lithography (that is, the printed part and the non-printed part are both flat) is subjected to pressure, so the ink occupying the layout spreads and expands, resulting in poor line drawing. Therefore, it was later improved to be called offset printing. The printing method is to make the layout into a positive pattern, transfer it to a rubber drum for reverse pattern when printing, and then print it with reverse pattern. Early lithography was plane lithography, but later ... >; & gt

Question 6: What kinds of printing are there? What is the difference? Lithography: offset printing; Relief printing: resin relief printing, letterpress printing, flexographic printing, rubber printing, etc. Gravure printing: Gravure printing, engraving gravure printing; Stencil printing: stencil mimeograph, hot stencil screen printing (integrated stencil machine) and screen printing; Transfer mode: water transfer, thermal transfer, etc. Digital printing: color laser, ink jet, etc. That's all I know.

What kind of economy depends on what kind of pattern is printed, how accurate it is, where it is printed and how much it is printed.

The silk screen printing on the schoolbag can be printed or thermally transferred.

Color separation is to divide colors into three primary colors: printing and black CMYK. Color separation is very simple, you can use related software. For example, coreldraw offset printing, which is more common now, is applied to paper.

It should be screen printed on the schoolbag.

As for film color separation, printing is generally divided into four colors, red, yellow and black. Four-color separation for printing

Basically, all colors are composed of these four colors, and the printing plate is also divided into four pieces.

Question 7: Besides letterpress printing, what other printing methods are there? There'd better be three. Urgent need! ! ! ! ! ! ! ! ! ! ! Engraving printing, aniline printing, stencil printing, intaglio printing, lithographic printing and relief printing.
