Make your own clear rubber stamps (polymer actually) to use on clay, polymer clay, fabric, paper, or anything else you can think of. This is an easy process that allows you to make stamps out of practically any black and white image you can come up with, and you can make them whatever size you like. They are also much less expensive than commercial rubber stamps. About 25 cents a square inch.
Step 1: Gather all your equipment and supplies
The process of making a polymer stamp is a fairly straightforward, once you know the basics. Simply put, Photopolymer is a liquid polymer that is reactive to UV light and will harden when exposed. Knowing this, a negative can be made that allows the UV light to show through only where the stamp image is to be. The negative and polymer is exposed and the excess polymer washed away, leaving your custom rubber stamp.
There are two pieces of equipment that you will need to make to expose your rubber stamps, although both are very simple to make. The first is the UV exposure light. If you think you might be doing a lot of rubber stamp making I would invest in a fluorescent light fixture with UV (black light) bulbs to fit. You will need to attach two 6 â x 6â wood boards to the side of the light to raise it 4â off of the table surface. Some light fixtures will need to have a cord attached, which can easily be done by cutting a 6â extension cords female end off and direct wiring to the fixture. To make the light fixture easy to use a on/off switch may be wired to the light as well to make turning off the light between exposures easier. Another solution for those who donât want to wire their light fixture is to simply purchase a clamp light and hang it 4 inches from the tabletop. They come with cords attached and a turn of button on the top of the fixture. You can purchase a flood style black light bulb to fit the fixture.
The second piece of equipment is the glass exposure plates. These are simply two matching sheets of 8 â x 8â single pain clear glass , with the edges wrapped in electrical tape to keep your hands clear of sharp edges. Along two parallel edges of the taped plates lay magnetic tape on both sides. This will hold the plates together and keep them from shifting during the exposure process.
