Most people want to know how to burn the image into the screen. It is probably the most difficult part of silk-screening but it is very simple to do. This tutorial is a simple outline of how to get your artwork from you transparency to the screen.
Let the emulsion dry for about an hour (or longer) in a dimly lit room. A fan should be placed about five feet away from the screen to assist in the drying process.
A piece of glass should be placed on the artwork. This will act as a vacuum so your artwork will not move while it's being burnt into the screen.
A black felt or cloth is placed beneath the screen to absorb light so that no light is reflected back up to the screen.
Burning times will vary, but ten minutes is a safe time. It is better to over-burn than under-burn the screen and emulsion.
After your screen is burnt. Take a spray bottle and mist the screen with water. Take your screen outside or to a sink or tub and rinse out your screen. If you are having trouble getting the emulsion out, you may have to increase the water pressure of your hose or sink.
You should be left with your image burnt into your screen. Once this step is complete, you are well on your way to printing t-shirts.
