About modern screen printing

Modern screen printing is not only technically different from the other three types of printing, but it is the most widely used of the four printing types. It can be printed on paper, cardboard, wood products, plastics, textiles, ceramics, metals, furs, and composites of several later materials. It can be used not only for printing flat objects, but also for printing round, convex, concave and irregular shaped objects. Because of this, screen printing is an inevitable product. However, since the technical details about it are a trade secret, its development is only going on quietly. But no matter what, it is continuously progressing and developing, and it has broad prospects.

The development of modern screen printing originated in the United States. From screen printing pioneers Harry Leroy Hiett and Edward A. Owens, screen printing began as early as the beginning of the 20th century (1901-1906). . The first screen-printing attempt was made by Francis Willette of Detroit, Michigan, which screen-printed on the felt pennants.

Screen printing is the attachment of a stencil with an image or pattern to a screen for printing. Usually the screen is made of nylon, polyester, silk or metal mesh. When the substrate is placed directly under the screen with the stencil, the screen-printing ink or paint passes under the squeegee of the squeegee and passes through the mesh in the middle of the screen and is printed on the substrate (the squeegee has manual and Automatic two). The stencil on the screen seals a portion of the mesh aperture so that the pigment does not pass through the screen, and only the image portion can pass through, so that only the image portion is imprinted on the substrate. In other words, screen printing actually uses ink to permeate through the printing plate, which is why it is called silk screen printing rather than silk screen printing or silk printing because not only silk is used as a screen material, nylon, Polyester fibers, cotton, cotton, stainless steel, copper, brass, and bronze can all be used as mesh materials.

Due to the continuous development of graphic reproduction technology, methods such as electrostatic printing, ink-jet printing, and pad printing have emerged, and some new methods do not require the application of pressure.
