Yet the silk screening process as we know it today originated in the early 1900s. The painstaking process Japanese printmakers went through, which involved gluing a spider-like network of human hair across the openings of oil-treated heavy paper sheets, can be seen as the antecedent of the modern silk screen method. In the 15th and 16th centuries, the Japanese often used stencils on cotton and silk for clothing and decorations. The origins of silk screen printing can be found in early prints, woodcuts and block prints of the Chinese Song Dynasty (960 AD – 1279 AD). The History and Development of Silk Screen Printing This method only works for solvent-based inks. The indirect method consists of first exposing the photo-sensitive film to the artwork, then developing it in developing solution or water, and applying it to the screen while still wet. Next, it is exposed to the artwork (the film positive) with a proper light source. In the direct method, photo-sensitive film or liquid emulsion is applied to the screen and allowed to dry. There are two methods of photographic screen printing. The film is then adhered to the screen, after which the printing process can commence. The parts that should be printed are then lifted away, and the film that is left will seal off the rest of the screen, preventing ink from passing through. The next step is to cut around the design, making sure not to cut into the backing sheet. The film is then taped over the design on the work surface. The process of the hand-cut film stencil is as follows: a piece of film, at least 1 inch larger than the artwork, is cut out. Next, once the glue coating has dried, kerosine is wiped over the surface of the screen to remove the tusche from the parts where the artist has drawn. The entire screen is then covered with glue. Lithographic TuscheĪnother option is to use lithographic tusche (a grease-based ink) to paint the design on the screen. Ink or paint is pushed through the screen onto the chosen material, using a rubber blade known as a squeegee. The block-out method consists of making a drawing or cut-out on the screen, and then coating the areas of the screen that are not to be printed with a sealer, like lacquer, shellac or glue, to prevent ink or paint clinging to those parts. For every colour an artist wishes to apply, a separate screen has to be used, with a different area blocked out every time. The simplest of these methods is the block-out method. Additionally, techniques such as the tusche method, the block-out method and the cut-paper stencil method are often used for fine-art printing. There are many different methods of silk screening, but two major commercial techniques account for about 95% of all the screen work: the hand-cut film stencil technique and the photographic technique.
