Basic Screen printing is a process using light-sensitive materials and film-positive images to print on paper, wood, plastic, fabric and many other materials. Once the image is on the screen, ink is pressed through the screen with a squeegee to create a print. Screen-printing ink is brilliant and creates a dynamic-looking print. It is possible to print multiple copies and to use one color of ink or multiple colors of ink. A screen must be prepared for each ink color use.
