Screen printing, also know as silk screen printing, is the process of using a framed mesh screen to apply ink to a type of fabric. The printer starts with supplied artwork and separate it into individual sections of colors. Each color requires its own unique screen. The artwork is exposed to light sensitive emulsion which is then washed away to create a stencil. Colored ink is added to each screen on a turntable machine. A squeegee is used to pull the ink across the screen and push it through the mesh and onto the garment. After each color is applied, the screen printed item is run through an oven to make the print permanent.
