The  image  to be printed is photographically transferred to a very  fine  fabric  (the  screen) such that the non-printing areas are blocked off and the fabric  serves  as a stencil. The ink is wiped across the screen to pass through the unblocked pores and reach the substrate. For each color  to be printed a separate screen is prepared and the  process  is repeated. There are three common types of screen printing presses. The ‘flat-bed’, ‘cylinder’ and the most widely used type, the rotary. Manual flat-bed screen printing is a slow process, done by hand. It is used by designer-makers for complicated fabric designs or for small runs. In image 1, the mash is stapled to a screen to make a screen. Then later masking tape is stuck to the outside of the screen. Then make a stencil with paper. The stencil is placed under the screen but on top of the paper.

A squeegee is used to draw ink across the screen. The screen is carefully lifted. Industrial flat-bed printing automates this process, with the fabric moved through the machine on a conveyor belt and the print repeating rapidly. This is used by designers for mass creation. Rotary screen printing is a mechanized version of hand screen printing. This process uses hollow screen-mesh cylinders and squeegee blades located inside the cylinders that force the ink onto the wall covering as it travels through a printing press. There is a separate screen for each color. Rotary screen printing allows for a heavy application of ink and a rich look – very similar to hand screen prints but at a lower cost. Stencilling is a method of imprinting designs or letters on paper, cloth, or other materials through the use of a perforated or cut-out device called a stencil. The technique is widely employed for decorating textiles, wallpaper, ceilings, and furniture and for printing signs, posters, and handbills. A design for stencilling is usually cut out of treated paper, plastic, or thin metal. The cut stencil is then fastened securely to the printing surface, and paint or ink is applied over the stencil with a brush or roller. When the stencil is lifted off, the design that has been cut out of the stencil is left imprinted on the material. The same stencil can be used repeatedly, and coloured inks or paints can be applied to produce multicoloured patterns.
