is a stencil method of print making
in which a design is imposed on a
screen of polyester
or other fine mesh, with blank areas coated
with an impermeable substance.
Ink is forced into the mesh openings by a
squeegee and onto the printing surface
during the squeegee stroke.
It is also known as silkscreen, serigraphy,
and serigraph printing.
A number of screens can be used to
produce a multicolored image or design. (Wikipedia)
