Screen printing, otherwise known as silk screening, is typically used in embroidery, T-shirt, and print shops. A design is drawn, typically using graphic design software, then transferred to a piece of vellum. The vellum is then placed onto a silk screen coated with emulsion and set under lighting to burn the design in. Emulsion is a solution used in many printing and photography labs, and can be made at home.
