1. Creating Your Image
When making your first attempt, you should start with a simple design without a lot of thin lines. A basic silhouette using Photoshop is the easiest way to go. You will need a solid black image, this is because its main purpose is to block off the light. The image you choose will be burnt into the emulsion in the fourth step four. Once you have settled on an image, print out the image on a laser printer onto a transparent paper (if you are not able to buy a box of transparencies, visit copy shops, they can copy the image for you onto a transparency for just a dollar).
2. Coat your Screen in Emulsion
Emulsion comes in two parts: the emulsion and the sensitizer. Mix the two together following the the directions shown on the bottle. Lay down the screen on a large bag. Proceed and pour out a little of the emulsion mixture onto the screen and then spread it out on the screen with the squeegee. A slightly larger area than the area you want to pint will be covered by the emulsion. You can repeat the process again until the screen is well coated and you can't see through it. You want an even, thin layer across the whole screen.
Leave your
screen in a black room for two hours till it's completely dry.
3. Exposing the Image on the Screen
It's now
the time to expose the screen on to the light. In that same black room (do not
turn on the lights yet),just lay down a black board or cloth. The, lay down the
frame and the screen with the screen side down on top of the black cloth. Now
lay the transparency with your image on it onto the screen where the photo
emulsion is placed. You should tape the transparency down with the scotch tape
or lay a small piece of glass over it.
Move the
lamp so that it's about one feet above the screen. Angle the lamp with the 250
watts bulb at the transparency with the image on it and leave the room. You
should not turn on any other lights. Wait for ten to fifteen minutes then
return to the room and carefully raise the transparency. You should be able to
see the faint blue lines where your image is burned into the screen. If the
image looks good, it's now time to clean it up. If the image does not look good
still, leave it for a few more minutes and then check back later.
4. Clean your Screen
Spray the
screen down with some cold water from a hose pipe, shower head or sink.
Continue to spray until you can clearly see through your image clearly. Hold
your screen up to the light so as to make sure that it looks exactly like your
transparency. Now let the screen dry up. Once the screen is dry, cover up any
exposed parts of the screen with tape.
Step 5: Print!
Lay your
t-shirt out on a clean flat surface. Stuff up a square piece of cardboard
inside the shirt, just underneath the area that you want to print on. Lay the
screen over the shirt, the design where you want to print it and Print!
