In the process of creating prints using a stencil, a screen made of polyester or another fine mesh is imprinted with a design, and any empty spaces are coated with an impermeable material. During the squeegee stroke, ink is forced into the mesh openings by the fill blade or squeegee and onto the printing surface. The ink is still on the substrate as the screen rebounds away from it. It is also referred to as silkscreen, serigraph printing, and serigraphy. Multiple screens can be used to produce a multicoloured image or design because one colour is printed at a time.
