Screen printing, or serigraphy, previously known as silk-screening is a printing technique that traditionally creates a sharp-edged image using a stencil and a porous fabric. In brief, the screen is made from porous finely woven fabric held over a frame. Areas of the screen are obscured with a non-permeable stencil which is a positive of the image to be printed (the remaining open areas are where the ink will appear). When printing multi-color logos, a new stencil is made for each color and the different colors printed sequentially. Screen printing is most suitable for logos with 1-4 colors that have no shading or color gradation.
