I purchased Halloween costume contest trophies to use as bowling trophies for a bowling outing. After peeling the 'Best Costume' sticker off the trophies, I was able to customize them.
CLEAR acrylic sheet with paper backing
Masking tape (optional)
Hot glue (optional)
X-acto knife, pin or nail (optional)
Step 1: Etch the image
Leave the paper protector on the acrylic. If your acrylic has a plastic film protector, peel it off, and replace it with a single layer of masking tape.
Laser etch and cut the plaque(s). Before removing from the etcher, inspect the plaque to be sure that all of the paper or tape has been burned through. It may be necessary to make a second pass.
Step 2: Paint the letters and graphics
For best results, paint several thin coats, to keep the paint from creeping under the tape.
Step 3: Weeding
It may help to use an X-acto knife, or pin to lift off small piece of tape.
Step 4: Background color
Step 5: Install
And because the paint is on the back side, the color and image will be protected.
Attach the plaques as you see fit. (We used hot glue.)
