Screen Printing & UV Curing
Screen printing is the most popular and matured printing technology as it has been practiced in the electronics industry for quite some time. Screen printing uses a screen to transfer ink to a substrate. The screen has a mesh in which a pattern is drawn. There are parts that allow the passage of ink (mesh image) and others that are impermeable (mesh emulsion). Moving a squeegee across the screen transfers the ink from the screen to the substrate according to the pattern on the mesh. Multiple layers can be printed on the same substrate using different screens. After printing, the ink has to be cured by temperature or UV light.
