But screen printing by hand, as is still done in San Diego, still has many advantages, enabling artists and crafts folk to provide images that are graphic, eye-catching and individual.

It originated in China then was adapted by the japanese in the shape of katazome. The Japanese used woven silk to make the mesh and lacquers to make stencils. The employment of silk is where screen printing got its another name - Silk screening or silk screen printing.

The modern screen printing process originated from patents taken out by Samuel Simon in the early 1900s in Britain. In fact one San Diego screen printer still offers local personalised delivery very similar to the olden days.

The use of photographic stencils at this time made the process more flexible and encouraged wide-spread use. The term silk screen has not been in use inside the industry since the mid-1940s when the employment of silk was discontinued due to its use in the war effort. This strategy of printing has become vital in the production of a wide array of manufactured items, including decorative panels, printed circuit boards, touch-sensitive switches, ...
... plastic boxes, and published garments. A fine man-made fabric or metal mesh is stretched over an oblong frame, and a photopolymer coating is applied to the entire surface. Exposure of the photopolymer thru a film positive causes it to toughen in the areas not meant to print. The unexposed material is then washed away to create the open areas of the stencil. In the printing press, this screen is pressed against the surface to be revealed, and ink is forced thru the open areas of the stencil with a rubber squeegee. The presses for screen printing range between straightforward manual devices for the small-scale printing of T-shirts and banners to massive sheet-fed presses for multicolor, high-volume commercial applications. The process is distinguished by its ability to print finely detailed pictures on virtually any surface, including paper, plastics, metals, and 3-dimensional surfaces. Compared to other printmaking strategies, it is more desirable because of its the low costs, even for great sizes. It is also the only major printing process that is frequently used to provide photographs that are not designed to be viewed. The circuit patterns in touch-sensitive switch panels, as an example, are screen-printed with special conductive inks.
