Screen printing is also called a stencil process of printmaking. In this method, a design is formed on the cover of fine mesh or silk by applying ink onto the printing surface through the mesh.
Other names of the technique include serigraphy, silkscreen, and serigraph. If you want to explore more about nylon mesh screen you can visit http://www.elkofiltering.com/store/p/399-Nylon-Mesh-1-Micron-Open-Area-1-Width-45-in.aspx
Traditionally, the technique was known with the name silk printing as silk was used in the process. But, presently, synthetic threads are getting used for the process. In this article, we'll discuss several things about the printing technique.
The screen developed from a finely woven fabric known as the mesh is stretched over the wood or aluminum frame. Nylon or steel is used for the woven of mesh. A non-permeable material is used to form a stencil to block off the screen area. Adding to it, the stencil acts as negative of the image to be printed on the screen.
Ink is placed on the screen top and the screen is placed over the paper or another substrate. And there is a full bar which is meant to fill the openings of mesh with ink. The ink present in the mesh is squeezed to the substrate in the prescribed amount through the capillary action. The snap-off action takes place when the squeegee is moved towards the rear of the screen. And this leads to leaving the ink over the surface of the substrate.
There are three different kinds of presses that are used for printing. Such presses are called 'cylinder', 'flat-bed' and 'rotary'.
Stencil for screen printing
Numerous ways are there to prepare stencils for printing. One of the methods is to cut the design from any non-porous material followed by attaching it to the screen bottom.
