The operation of the screen printing
Screen printing is a printing stencil form, improved and automated. The screen is a nylon fabric (or polyester) stretched on a wooden frame (or metal), which makes the stencil with the shape or the text to print. The artworks are deposited (film containing the transparent document to see), we apply a photosensitive emulsion and the screen is exposed to ultraviolet rays, during a given time. Cooking by insolation and rinsing the screen with water give rise to the impression matrix. It is deposited on the object to print, and then the ink is applied from above using a squeegee. There are several colors to apply, whether to manufacture several screens.
Screen printing has many advantages: it allows to print objects with an original and creative way, on all types of media, regardless of their material. In addition, it is particularly useful in the industrial sector.
