The origin and development of hole printing
Hole printing, like movable type printing, is widely recognized as one of the ancient inventions of China.Screen printing is gradually developed from carving hole plate.Screen printing originated in The Qin and Han Dynasties of China, the valerian printing process, since now has a history of more than 2,000 years.
In the Song Dynasty, screen printing took another leap forward, that is, in the screen printing dye into glue powder (starch), blending pulp for printing.Using paste printing to improve the original use of oily paint, with this paste printed prints appear more colorful, printed patterns more beautiful and moving.This kind of silk-screen printing technology soon spread to Europe, Germany and Italy first adopted this printing process.Many foreign scholars studying screen printing have to admit that screen printing is a great invention of China.
Tang culture spread east to Japan, Korea (Korea), west to the Middle East and Europe, at the same time spread to the Western carving paper plate technology.
At the beginning of the 18th century, Samuel Simon, an Englishman, was inspired by the engraving technique and began to attach a carving plate to a wooden frame covered with silk mesh, so that more delicate patterns could be engraved on the plate without scattering.Jonhn Brusvaz devised a method of silk-screen multicolor overprinter for the printing of billboards.Later, it was widely used in commercial printing.
There is a Japanese painter named Wan Shi, is the founder of Japan’s modern screen printing, Japanese painter Wan Shi and Xizheng returned to Japan in the United States in 1917, this new printing method and screen printing plate painting skills back home, and carried out research, so in 1923 obtained the “polymerization printing plate” patent, 1924 completed the study of direct photosensitive plate.In 1923, a joint venture color printing technology company was established in Shiyubashi, Tokyo. Efforts were made to improve it. Another type of varnish paper engraving platemaking was completed using Japanese printing and dyeing stencil technology.This method was later imported into the United States.
It was not until the second half of the 1940s that screen printing began to use photosensitive materials to make plate making possible the screen printing of precise images. Screen printing began to be used in the manufacturing of printing circuits and thick film integrated circuits.Used for photographic pattern of sensitizer initially mainly adopts dichromate salts, 50 s, people put the vinyl acetate polyvinyl alcohol emulsion polymerization in aqueous solution, emulsion, and join the dichromate emulsion, TuFeng directly on the screen, as a photographic film, which is then direct photographic pattern method is widely used.As a result of the 6-valent chromium pollution regulations become more and more strict, since the 1970s screen plate began to use diazo resin as a comprehensive photosensitizer.
Since then, screen printing has been widely used in the manufacture of printed circuit boards and thick film integration circuits.Screen printing has become an indispensable part of the electronic component manufacturing industry, and the accuracy and stability of the printing plate are increasingly required.At the same time, began to screen pre – coated plate research.Since the 1980s, the development of sensitive materials in the specific nitrogen resin more stable photosensitive resin, so that the screen precoated plate has been the real application.
Screen printing inks have also been gradually improved, from the previous potential solid inks to uv curing inks using photosensitive curing resin as a binder.At the same time, the development of water-based ink with water-soluble binders as the carrier, so as to replace the previous need by organic solvents as the carrier of soluble ink.
Screen printing machine from manual semi – automatic, automatic and automatic direction of development.The printing speed also increased from the semi-automatic printing speed of 700 sheets per hour to the automatic printing speed of 1500 sheets per hour, and the printing speed reached about 2500~3000 sheets per hour from the flat printing to the rotary rotary screen printing.
The development of screen printing has broadened its application to include textile, ceramics, signage, advertising, thick film super-integrated circuits and thin film superconducting materials.
