Using colour matched and automotive industry approved inks GSM uses its screen printing technology to transfer ink onto a substrate (aluminium, stainless steel or vinyl), except in areas made impermeable to the ink by a blocking stencil. A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact. 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. The part then passes through a drying process following which a lacquer may be applied.
