What is an original silkscreen print (serigraph)? Original prints are original works of art made individually by hand. They should not be confused with commercially published reproduction prints which, even though they may be signed and numbered, are merely copies of existing artwork, Nor should they be confused with "giclée" prints which are computer generated copies of existing artwork: "giclée" is simply a French word for "inkjet". Traditionally, an original print involves the artist preparing a plate, block, stone or stencil from which to take a number of impressions on to high quality paper. This is called an edition; the prints are then individually titled and signed by the artist. They are usually also numbered (eg "5/20" identifies the fifth print in an edition of twenty prints) before the plate, block or stencil is finally destroyed.

Silkscreen printing is a sophisticated version of stencilling, for each colour, a stencil is applied to a tightly stretched screen of fine mesh (usually a polyester fabric rather than silk these days). Thick ink is poured onto the screen and pressed with a "squeegee" through the open areas of the screen onto the paper beneath. The whole edition is printed in the first colour and then, when dry, overprinted with the next colour.

Stencils can be made of cut or torn paper, masking fluid painted directly onto the screen, or by using a photo sensitive stencil film which can reproduce a photographic image (such as Andy Warhol's "Marilyn") or any drawn or painted shapes.

Aside from the obvious benefit of producing an edition of prints, making the artists work more available and affordable, the technique of silkscreen printing has its own special qualities. One of its beauties is the ability to create pure, crisp areas of colour.
