A fine-mesh screen, made of silk, polyester or stainless steel, is used for
screen printing. The screen is held in a frame as shown in the figure below. A
stencil containing the design is placed in the frame, covering the holes in
the screen where no ink is desired. The stencil is often produced with a
photographic process. The screen is placed on the part and ink is deposited in
the frame. The ink is then forced through the screen by moving a blade across
the screen. The screen is lifted and the part is finally allowed to dry.
