THE
Process begins with a fine nylon mesh stretched on a aluminium or wooden frame.This
mesh is coated with a light-sensitive emulsion or film which when get dried blocks
the holes in the mesh.The image to be printed is in the form of transparent film.The
transparent positive film and the coated and dried mesh are placed togather and
then exposed to Ultra-violet light.Then a jet of water is used to wash the coating
which has not been hardened by the Ultra-violet light,this makes a screen stencil
same as the transparent film image.
