Screen printing.

Screen printing is one of the most versatile processes for transferring ink and technical coatings. The range of inks is varied.

Screen printing is a push-through process, a special type of stencil printing, which means that during the printing process the ink passes through the screen and onto the substrate.

The modern screen printing process originated from patents taken out by Samuel Simon in 1907 in England.

Printing unit: frame(2), printing plate (screen, stencil), blade, squeegee, paper, base plate (print body).

The ink is first spread over the plate by a squeegee as evenly as possible and with virtually no pressure. This takes place without contact between screen and substrate. The ink is then pressed through the plate and onto the substrate with a higher squeegee pressure. The wetting connection between ink and the surface to be printed is produced by this process, which is followed by the separation of plate and substrate. This process is particularly well-supported by the fact that the screen is not placed directly on the substrate, but rather at a certain distance above it and only comes into contact with the surface to be printed as a result of the squeegee.

There are three types of screen presses: flat-bed, rotary screen printing, cylinder screen printing

Advantages:

-universality. Printing can be done on paper, textiles, ceramics, and plastics.

-special impression strength, because thick layer of ink.

Disadvantage: all parts of the stencil must be connected to each other.(does not occur with screen printing)

Products: art prints, posters, greeting card, labels, menus, program covers, wallpaper and textiles such as table cloths, shower curtains and draperies.
