Screenprinting is a process where ink is forced through a mesh screen onto a surface. Making certain areas of the screen impervious to printing ink creates a stencil, which blocks the printing ink from passing through the screen. The ink that passes through forms the printed image.
A printing screen consists of a fine mesh fabric that is tightly stretched and attached to a metal or wooden frame. Traditionally these screens were made of silk, but today they are most often made of synthetic materials such as terylene.
