Stencil Dyes are great if you want to create a custom stamp for your disc. Single color images are best for stencil dyes. There are two different methods to dying the disc once you have applied your stencil. For both method you need to buy a packet of Idye Poly from online or a local craft store. Black is best for most disc plastics because it is easily seen on a variety of plastic colors. There are some other dyes that also work but Idye poly gives the best results.
The first stencil dye method is the heat method. Mix your Powder of Idye Poly into a mason jar or some other type of container. I like the liter mason jars. Fill the jar up with water and mix in just the powder dye packet. The package comes with a color enhancer but you do not need it. Once you have the dye powder mixed with the water, pour the dye into an old frying pan that is bigger than a your disc golf disc. You want to fill the pan with the dye mixture so that the disc can float on top without touching the bottom of the pan. Heat the pan on the stove on very low heat. You don't want the water to boil or simmer because the heat can warp your disc.
At this point the dye should be ready for the disc. Your stencil should already be placed on your disc and all air bubbles should be squeegeed off or not touching the edge of the design. The dye mixture will fill into any air bubbles or cuts in the stencil and can ruin the crisp lines that you want.
When you think that your stencil is applied properly you can now start the dyeing process. It can be helpful to tape on some handles to the back of your disc so that you can easily place and take off the disc from the dye mixture. When placing the disc on the dye you should start by placing the disc down on on edge at an angle close to 45 Degrees. Then ease the rest of the disc onto the dye mixture until it floats by itself. If you set the disc down parallel to the dye mixture there is a higher chance that air bubbles in the dye mixture make it so parts of your stencil design don't get dyed evenly. You can place the disc down and then check it after about 30 seconds to ensure that no bubbles have shown up on your design. If you are happy with how the disc is laying on the dye mixture then all you have to do is wait. I would recommend letting the disc sit for 5 to 15 minutes depending on the type of plastic. Star type plastic will dye faster than Champion type plastic. Be sure to monitor the disc while it is on the dye. If the water is too hot it can warp your disc and/or the stencil could come off the disc.
After the 5 to 15 minutes the disc should be dyed. Move the disc to the sink and rinse off the remaining dye with cold water. The cold water will seal the plastic better than warm water. When the disc is dry you can remove your stencil and view your handy work.
Stove Top Method
These discs were all dyed using the stove top method. The clock stencil was cut using a vinyl plotter. If you plan on doing a lot of stencil dyes or cutting vinyl stickers, a plotter is highly recommended.
