A screen is made of a piece of mesh stretched over a frame. A stencil is formed by blocking off parts of the screen in the negative image of the design to be printed that is, the open spaces are where the ink will appear on the substrate.
Screen Printers use a silkscreen like this Screen stretch version, a squeegee, and hinge clamps to screen print their designs. The ink is forced through the mesh using the rubber squeegee; the hinge clamps keep the screen in place for easy registration.
Silkscreen printing is more versatile than traditional printing methods and is used to create prints on a wide variety of materials such as textiles, ceramics, wood, paper, glass, metal, plastic and product labels. The technique uses a stencil attached to a woven mesh through which the ink is transferred onto the chosen material.
There are three common types of screen printing presses. The flat-bed, cylinder, and the most widely used type, the rotary.
Textile items printed with multicolored designs often use a wet on wet technique, or colours dried while on the press, while graphic items are allowed to dry between colours that are then printed with another screen and often in a different colour after the product is re-aligned on the press.
