SilkScreen printing

Screen printing is a printing method where a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil.Prior to the invention of polyester mesh silk was used in the process. A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, then a reverse stroke causes the screen to touch the substrate momentarily. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed.
