Serigraphy, also known as silkscreening or screen-printing, is the process of producing an image, or serigraph, by pressing color though a fabric stencil comprised off porous and non-porous sections. The serigraph may be produced onto a fabric, such as a t-shirt, or other material such as ceramic, paper, or wood.

Serigraphy is said to be based on the Japanese art of katazome, a form of stenciling using waterproof papers that was used in ancient Japan to copy an image. Some say however, that the art originated in the Fiji Islands where banana leaves were used as stencils. The art of serigraphy as it is known today was patented in England in the early 1900s. The first commercial use of serigraphy in the United States occurred in 1914 when John Pilsworth developed a process to produce multiple multi-color prints from a single fabric screen, which was used to make multicolored signs and posters.

During the First World War, serigraphy became the preferred method for printing flags and other patriotic banners because of its ability to create relatively identical and multi-layered images. More recently, serigraphy has been used by artists and manufacturers alike. In fact, most of us probably own a serigraphed t-shirt and many of us have seen Andy Warhol's use of serigraphy in conjunction with photographic headshots of famous people such as Marilyn Monroe.

Serigraphy is a relatively straightforward process. A piece of porous fabric is used as the screen. Originally, that porous fabric was silk, hence the name silkscreen, but today, the more inexpensive alternatives of polyester or nylon are more commonly used. That porous fabric is tautly stretched across a wood or metal frame. Then, the negative areas of the image to be produced are blocked off on the screen with a non-porous material which can be paper, fabric, or plastic. This creates the stencil.

The screen, with the stencil in place, is then placed over the final product, such as paper or fabric. Ink, whether water- or oil-based, is spread evenly over the screen. A rubber squeegee is then used to press the ink through the porous areas of the screen and onto the paper or fabric below. If the design calls for multiple layers or colors, the ink from the first press is given time to dry, and the process is repeated with a different stencil or different ink color.
