Using plate or other means of transferring information from the graphic on the manuscript to the technology on the substrates.
Printing was one of the four great inventions in ancient China,. It and the compass, gunpowder, paper-making, known as the four great inventions of ancient China.

The invention of the printing press, is the representative of the ancient working people's wisdom in our country, its contribution to human civilization is immeasurable. Therefore, someone put printing was known as "the mother of civilization", this is again appropriate did not pass.
concept
In terms of literal meaning, with a trace of printing, inunction of brush. Use brush to clean and make the signs of the from other objects, without printing. In short, the printing is the production of print industry. The production of print, similar to seal. Carving seals (version) first, and then make the seal (version) stained with ink filters, then seal (version) the user on the move from paper, silks, leather substrates, such as printed matter.

In terms of scientific views, where in the object (narrow sense only in terms of paper) the traces, and the marks (more than the amount of copy) to the illuminate of light reflection or absorption, through the human eye, make the person's visual nerve identify shapes and colors of the trace, of the printing.
In terms of cultural point of view, the printing is a way to express and spread human thought. Printing in ancient China, the brush dip ink coating on plate, coated paper in the space, then use the other for brush brush the back light, the paper is on a raised reverse writing ink, namely the printed text for positive ink on paper, because of a brush for a quick print, therefore calls the printing.
As a general rule, the printing is a method to directly or indirectly, the image or text manuscript for plate, coated with pigment ink on edition, by the pressure transferring pigment ink on paper or other substrates, and quickly a large number of replication of an industrial project.

Now already don't brush seal, even have no pressure, which can print out copies to printing method.
The development history
China's printing, has a long history, guangyuan. It is the important part in the Chinese culture; It along with the birth of the Chinese culture germination, along with the development of the Chinese culture evolution. If from its origin, has experienced the origin, the ancient, modern and contemporary four historical period, for the development of more than five thousand years. Early times, people experience and knowledge in order to record events, propagation, created the early text symbols, and seek to record these characters of medium. Due to the limitation of the means of production, people can only use natural objects to recorded text symbols. For example, write the word engraved, in rock, leaves, animal bones, stones, bark and other natural materials. Due to the very expensive recorded text materials, therefore, can only be important events recorded briefly. Most people's experience, relying on oral transmission, which seriously affects the development of social culture.
The seal picture
The invention of printing, greatly changed the face, people can experience written, large number of replication, transmission, that is the culture of social face great changes have taken place, so that more people have the opportunity to study.
With the passage of time and the development of social and cultural processes, in Chinese neolithic period, and is used to score, printing, text symbols and patterns and bark cloth printing process manual sculpture technology, gradually by the rough, rough score and to develop in the direction of complex and delicate, specification inscribed. Before the 11th century BC shang Yin period, has been used in oracle bone carving the words. In the western zhou dynasty, engraving technology combined with ancient smelting technology, emergence and development of the casting bronze vessels or engraved text. Dynasty qin, the wind of carved stone is increasingly prevalent, makes the old manual sculpture technology leap progress from both quantity and quality, and is the first stamp company chop. Made great contribution to the development of China's cultural undertakings. At the same time, also for manual sculpture technology further development and perfection, creating opportunities and conditions. The lute stamps, stamps since the qin and han dynasties tile, belongs to the hand-carved extension in the field of application and transfer copy technique is widely used. As for then rubbing technique and further development of the fabric printing, it essentially is the prototype of the printing press.
classification
Printing can be roughly divided into four basic categories: (a) letterpress printing; (b) gravure printing; (c) lithography; (d) hole printing.
Letterpress printing method is one of the most ancient. It is the use of a convex surface of letterpress printing. Printing, the printing ink coating on the surface of matrix, and then to stamping on the paper, the font on the surface of the ink is transferred to the paper surface, forming a mark. Hand printing, Lionel whole line typesetting machine printing, stereotype, electric printing and photoengraving belong to letterpress printing.
Gravure printing is by manual or mechanical engraving carved to delimit line, make the print form a concave down a word or a printing method of the image. Printing, first put the ink filling line or groove, reoccupy prepared paper pressure on it, the paper put the ink stick, formation of imprinting. Etching, needle etching and gravure are intaglio printing.
Packaging and printing
Packaging and printing
Lithographic printing is also sometimes called chemistry, mean printing images and print in the same plane. It is based on the principle of "oil and water don't mix" implementation of printing. This type of printing is by mechanical or manual image shows in the stone or metal surface, and then to the surface for chemical treatment makes the image part of ink, and other parts of the blank is not close to the ink. Printing, only close the ink on the part of the image is transferred to the paper, form the imprinting. Photocopy of printing, photolithograph and offset printing are lithography.
Hole printing including hectograph, ornamental Kong Hua version, spraying, silk screen printing and so on. Hole is the principle of printing: printing plate (paper film version or other version of the version made by ink on the base of perforation), when printed by certain pressure to make ink through hole version of perforation transferred to substrates (paper, ceramic, etc.), to form the image or text. Hectograph print is the easiest hole printing, began in the late 19th century. This kind of printing is on the special wax paper, through a typewriter or pen made of wax paper version, printing ink roller on wax paper edition, can get ideal printing effect on substrates. In the hole printing, screen printing is the most widely used.
Silk screen printing
Modern screen printing not only in technology is different from the other three types of printing, and the four types of printing in one of the most widely application scope. Its printing object can be paper, cardboard, wooden product, plastic, textile, ceramic, metal, fur and after several materials of synthetic materials. It not only can be used for printing graphic objects, and can be printed circle, convex, concave, and irregular shape objects. Because of this, screen printing is an inevitable outcome. However, due to the technical details about it is a commercial secret, its development is in quietly. But anyway, it is in constant progress and development, and broad prospects.
The development of modern silk screen printing originated in the United States. Harry from the pioneers of silk screen printing, larry, hite (Harry LEroy Hiett) and Edward owens (Edward A.O wens), silk screen printing as early as the beginning of the 20th century (1901-1906) had already started. Screen printing is first attempt by the United States Detroit, Michigan of the Buddha's soft, Willie (Francis Willette), it has carried on the silk screen printing on the fleece pennant.
Screen printing is to put the template is attached with a image or pattern on the silk screen printing. Usually screen made of nylon, polyester, silk or metal mesh. When substrates directly under your screen with a template, silk screen printing ink or paint in the middle of the scraping blade pressure through the screen mesh, printing on substrates (scraping blade in both manual and automated). Template of silk screen on the part of the screen hole seal makes pigment can't through the screen, and only the image part can go through, so only image parts have the imprinting on the substrates. Silk screen printing, in other words, in fact is the use of ink penetration of a plate for printing, it is said it was not called silk screen printing mesh printing or silk printing, because not only silk used for silk screen materials, nylon, polyester, cotton, cotton cloth, stainless steel, copper, brass and bronze material can be used as a screen.
