Screenprinting , ( Silkscreening) uses a stencil and porous fabric (typically polyester or nylon) to create images on various types of material. The screen is non-permeable except for the section of the screen which is a positive image of the item being printed. This is where the ink/paint is transferred through the screen using a rubber blade and applied onto the object being screenprinted. In multi-coloured printing, each colour is allocated to a screen and this process is repeated allowing the ink/paint to dry inbetween colour applications.
Screenprinting is commonly used in promotional product printing to create images on clothing, hats, bags, compendiums, umbrellas, water bottles, ceramic mugs, glass, metals, wood, and many more obscure items such as the electromagnetic faces of Palm Pilots and watch faces.
Screenprinting is typically a low cost printing method and is therefore often preferred over other processes such as dye sublimation or digital printing which are much more costly to reproduce.
