Modern silkscreen printing
Different from the other 3 printings in regard of technologies, silkscreen printing is the most widely used one. It can use paper, paperboard, wood, plastics, textile, metal, feather or composite material as printing stocks. Not only prints on plane surface, silkscreen printing can also print on round, raised, cupped or irregular surface. However, its detailed technologies are still regarded as business secrets.
Modern silkscreen printing was invented by Harry Leroy Hiett and Edward A.Owens in US in the early days of the 20th century. The first try was made by Francis Willette, who carried out the printing on a felt-cloth triangular flag.
Silkscreen printing is conducted by attaching the plates with images to the silkscreen. The silkscreen is generally made of nylon, polyester, silk or metal net. When the stock is directly placed under the silkscreen with plates, the ink or pigments travel through the net holes under the pressure of the doctor to print on the stock. The silkscreen is not only made of silk, but also nylon, polyester, cotton textile, cotton cloth, stainless steel, copper, etc.
