Screenprinting - 1 of 3
WHAT IS IT?
An open mesh fabric is stretched over a frame and areas blocked out to create a design. Ink is then forced through the mesh with a squeegee onto a surface below. The design can be applied in a variety of ways using torn or cut paper, a screen filling solution, backed printing film or photo emulsion.
Printing can be carried out using simple wooden frames right the way through to fully mechanised printing beds and tunnel dryers.
I use aluminium frames covered with a monofilament mesh of 100TPI (threads per inch). This give me the level of definition I want in my prints.
As screen filler I use backed printing film or photo emulsion mostly.
Whatever initial idea or image the print is based upon it will be printed out as a series of individual
colours, each requiring a separate screen. The first task is to create a black and white image for each, useful for hand cut designs but necessary for photo emulsion screens.
HAND CUT STENCILS
For hand cut stencils I use a propriety stencil material, a layer of film on a polyester backing. With the material tacked over the design, areas of the film can be cut and lifted away leaving the backing complete.
