Re: Printing a digital image into the body of an electric guitar.

To expand a bit:

The screen is a mask or stencil for applying the color. It's a fine,
open rayon, I think, and you stretch it across a frame. You mix the
sensitizer chemical into a sort of latex paint, and paint that onto to
screen, allowing it to dry for a time in a dark place. Exposure to
light renders the paint insoluble in water.

Print up a black and white transparency of the design. If you want to
use two or more colors you'll need a seperate transparency for each.
Take the dried screen out of the dark, lay the transparency on it, and
expose it to a strong light. The directions with the photoresist gick
will tell you all the right times, temperatures, and so on. You'll see
a color change in the parts of the screen that are exopsed to light.
After you've got the correct exposure you can wash out the screen, and
the parts that were dark in the transparency will be open so that the
ink can go through.

Screen printing ink is fairly thick, and you apply it with a squeegee.
Lay the screen down on the surface, force the proper amount of ink
through _making sure the screen doesn't shift_ and lift the screen
straight off.

Since you've got the screen, get some of the ink that they make from
printing on cloth, and make a few T-shirts with the same design. What
the heck.
