About : Screens

Screens are made up of wooden or metal frames with a polyester fabric glued on to one side. The thread count per inch or the mesh count on this fabric ranges from 24 to 385. Higher mesh count is used if your artwork has fine details. Blank screens are coated with photo sensitive emulsion and dried in a dark room for several hours. Now we take the film for each color of your artwork and expose it in an exposure unit for a short time. Each color is exposed on a separate screen.

After exposure screens are washed with water in a wash tank. The emulsion in the areas on the screens blocked by the dark on the film are washed away. While the areas where light shines through the film are hardened. Screens now have the image of your artwork. Ink will pass through the clear areas where the emulsion was washed away.
