Screen printing is a printing technique that uses a screen to support an ink-blocking stencil to receive a desired image. The stencil maybe some place on top of the screen, painted on with block solution, or through photographic process. However the stencil is apply, the result is the same. There are open areas and blocked areas. When ink is pulled across the screen using a squeegee, the ink is forced through the open areas and blocked by the filled areas. Thus the image is transferred to whatever lies beneath the screen.
Below are links to documents that describe the general techniques for reduction stencil screen printing and protographic processed screen printing. These are handouts for the Printmaking class at NHIA.
So far, in my course work at NHIA I have only attempted one screen print through the direct stencil reduction method. I used the same image I used in my first lithographic example, so that I would have some comparison between the two methods of printmaking.
