The Techniques of Screen Printing The screen printing process may not be known to everyone, and so here we will give some background about this method. Basically, screen printing means the method in which paints are pushed through a screen composed of fine mesh which does not let all paints go through, and thus creating a design imprinted on the other material. You may have known this method in another terms as silkscreen, silk-screening and serigraph, of which printing screens using original material were used to design prints. The most common materials used as substrate, the surface that is being printed, are paper and fabric. Screen printers have two sides, the substrate and the squeegee sides, wherein the screen gets in contact with the substrate while the other side has the squeegee pushing the ink through. The purpose of the squeegee is like the wiper wherein the paint or ink is squeezed through the wire mesh, and then onto the substrate creating the design. You can have a hard or soft squeegee, with blades either square or round or pointed edges to create the design on the various substrates.
Why Options Aren’t As Bad As You Think
The most common hardness of the squeegee blade is 70, wherein the durometer is the number used to indicate the hardness, wherein as the number goes up, the harder the blade is. Soft round squeegees are preferable for fabric used and the sharp edged and square squeegees are for non-porous surfaces.

The material for screen mesh used in printing is a polyester with a thread count of 40 to 400, and as the higher thread is counted the less ink let to go through. The colors of screen mesh can be white or yellow. These color choices can make a difference between sharp or soft images. A softer line is created using white mesh because of the light exposure, while a sharper image is created with a colored mesh because of the less reflection it creates. Maybe the last component to mention but not of least importance, is the screen printing frame that holds the screen mesh. It is made of wood or aluminum with pre-tensioned frames with rolling bars to tighten the mesh. Artists and printing houses use this printing technique to produce their projects on papers, plastics, cloths, leather, glass, wood, rubber and other materials. Screen printing uses two types of screens and these are the temporal screens and the permanent screens. The temporal screen can only last for a short period of time and can register single or limited prints on cloths and papers. The temporal screens are very easy to prepare, does not cost much money or effort, and examples of these are the paper stencil screens and the candle wax screens. On the other hand, the permanent screens, as the name represents, can last a very long time, and in fact if properly maintained, can last forever. You can use this type of screen for multiples, hundreds and thousands of prints. For this type of screen, preparation needs a considerable effort and would cost you more money, and the examples of this type are photographic screens, lacquer screens and shellac screens.
