The origin of technology
Stencil printing is the simplest form of orifice printing, dating from the late 19th century.This kind of printing is made on special wax paper, which can be made into a version of wax paper by typewriter or iron pen. The printing can be carried out by ink roller on the wax paper version, and the ideal printing effect can be obtained on the substrate.In orifice printing, the most widely used screen printing
Screen printing is the use of silk fabrics, synthetic fiber fabrics or wire mesh tension on the screen frame, the use of hand-carved lacquer film or photochemical plate printing screen.Modern screen printing technology, is to use photographic materials produced by the method of photographic plate making screen plate (make the silk screen printing on the graphic part of the screen hole to hole, rather than the graphic part of the screen hole is plugged) oil paintings, prints, posters, business CARDS, book covers, product packaging, product tags, printing and dyeing textile, glass and metal plane carrier, etc.
Screen printing has the advantages of large volume, low price, bright color, long shelf life, fast delivery, etc., it is recognized by more and more industries and widely used.On the circuit board of domestic electric appliance, the pattern on textile, the design on T-shirt, cultural unlined upper garment, shoe, the words on the face plate of freezer, TV set, washing machine, the adornment on ceramic, glass, wall tile;Various commercial advertising platforms, such as electric appliances, packaging, outdoor, fixed and mobile advertising platforms;In packaging decoration industry first high-grade packaging printing, packing, cigarette packs, wine package, especially the large packaging and product appearance abnormal widely applied decoration, silk screen printing, is closely linked with our life, its technology is controlled by a great number of printers and the small, personalized silk screen printing technology to teach at home are few, broad market anomalies!
Since the 1980s, China has accelerated the development and development of screen printing materials, equipment and technology, making screen printing competitive with flexible printing, offset printing and gravure printing.It's growing at 7 percent a year.More than 70 percent of wide - format color screen printing using spot color printing, nearly 30 percent of four-color overprinter, and the proportion of four-color overprinter is still steadily increasing.Industry survey results show that 70% of the annual output value of enterprises is around 1 million yuan.However, China's screen printing output value accounted for less than 2 percent of the total printing output, there is still a great potential to dig, development prospects are wide.
