WHAT IS SCREEN PRINTING?
Screen printing, also known as serigraphy, is one of the best-known methods of printing using a stencil process.
The screen printing technique is based on a simple principle. A printing screen is mounted a very small distance above the object to be printed. This screen consists of a frame and a fine mesh; the special mesh is made in any one of a number of different screen fabrics. In most screen-printing jobs, a polyester mesh is used, which produces a very accurate print result. A stencil is laid on top of the mesh. This is impermeable to ink in those areas where none should be printed. The ink is spread evenly over the stencil using a squeegee and penetrates through the screen, thus printing the design onto the printing surface.
One advantage of screen printing is the ability to vary the size of the mesh aperture. This means that a lot of different colour systems can be printed.
A very wide range of materials and shapes can be printed using the screen printing method. Fields of application range from flat surfaces, such as films and foils, to contoured surfaces, such as bottles. It is mainly paper and cardboard, and plastics and textiles that are printed on. But other materials such as ceramic, wood, metal and glass can also be printed on with the screen printing method.
