More Than You Want To Know About Screen Printing

A Brief History

SILK SCREEN PRINTING has its origins in Japanese stenciling, but the screen printing process that we know today probably stems from the patents taken out by Samuel Simon of Manchester at the turn of the century. He used silk stretched on frames to support hand painted stencils, a process also used by William Morris. In 1914 John Pilsworth of San Francisco also took out a patent for multicolor printing, using the screen process.

During the First World War in America screen printing took off as an industrial printing process; it was mainly used at first for flags and banners but also for 'point of sale' advertising in the chain stores in America, which were appearing around that time.

Around this time the invention of the photographic stencil revolutionized the process; in the following years, obviously improvements were made in the presses, inks and chemicals used, but apart from the introduction of computer technology in the 1980's - in the pre-press side of screenprinting - very little else has changed since.

Walk down any High street and you will see examples of SCREEN PRINTING everywhere: in shops you will see displays and posters advertising their products; you will see buses with ads on their sides; on computers and hi-fi you will notice badges and control panels; all these have been screen printed. In the home you will find that many textiles and items of clothing, sports bags and T shirts have been screenprinted, as well as the stickers that you have on the rear window of your car.

Artists have also used SILK SCREEN PRINTING, especially since the days of POP ART in the sixties - Andy Warhol ,Rauschenberg and Hamilton are a few notorious examples. These artists opened up a whole new vista in the use of the screen process.

How does screen printing work?

The equivalent of the printing plate for the screen printer is the SCREEN - a wooden or aluminum frame with a fine nylon MESH stretched over it. The MESH is coated with a light sensitive emulsion or film, which - when dry - will block the holes in the mesh. The image that needs to be printed is output to film either by camera or image-setter. This film positive and the mesh on the screen are sandwiched together and exposed to ultraviolet light in a device called a print-down frame. The screen is then washed with a jet of water which washes away all the light sensitive emulsion that has not been hardened by the ultraviolet light. This leaves you with an open stencil which corresponds exactly to the image that was supplied on the film. Now the screen is fitted on the press and is hinged so it can be raised and lowered. The substrate to be printed is placed in position under the screen and ink is placed on the top side of the screen, (the frame acts also as wall to contain the ink ). A rubber blade gripped in a wooden or metal handle called a SQUEEGEE (not unlike a giant windsheild wiper) is pulled across the top of the screen; it pushes the ink through the mesh onto the surface of the substrate you are printing. To repeat the process the squeegee floods the screen again with a return stroke before printing the next impression.

Screen Process Printing - Silk screen.

we handle both commercial and artistic screen printing. We can print on a wide variety of materials and products that other processes couldn't cope with; amongst these, plastics, glass, metals, wood, textiles and of course paper and board. We can also screen print on 3D objects such as control panels, components and promotional goods. All our printing is done by hand and our presses will handle anything as small as a button to a 60 x 40 inch section of a billboard. We can accept artwork on disc, by email and camera ready artwork is also acceptable. If on the other hand, all you have is a sketch we can produce the artwork for you.

Various applications for screen printing include: Posters, stickers, showcards, ticketing, shelf strips, banners, exhibition panels, plaques, ring binders, mouse pads, site boards, signs, T Shirts, to name but a few.
