Just joined this forum. I read some tutorials here, as well as watched some on youtube as to how to dye.
Just thought I'd post my technique and success story. This is my first dye, but it went well, and my technique is a combo of a few things I've seen. I dyed an Innova Champion Groove.
Supplies (all are cheap, <=$5):
Liquid Rit dye
Acetone - not nail polish remover, it's usually really diluted and won't work. Adhesive remover is fine, usually the main ingredient is acetone. I recommend using gloves for acetone, it's cancer-causing. And try not to breathe it - use it outside or something.
A cup and a brush. And a sink, with running water. Rit dye WILL STAIN plastic and worn sinks. Stainless steel doesn't stain. You can always just rinse it off outside.
1: Printed out my symbol i made
, then smoothly taped it to some contact paper. You might note the outline I made, which I found quite helpful. The inner circle of a disc is roughly 6in, so I would keep your design 5.5in or smaller.
Then I taped the contact paper to a cutting board. Then I carefully cut it. I learned that with an ex-acto knife (or similar design knife), the pressure you apply to the knife will not change its direction, but only turning it will.
2: Removed the stamp. Of course, acetone is the best. I had "goo off", which worked fine. Pure acetone is better. Just rubbed it with a rag after applying acetone. I recommend using gloves for acetone, it's cancer-causing. And try not to breathe it - use it outside or something.
3: Mixed liquid Rit dye (black in this case) with rubbing alcohol. I've seen a dye:alcohol ratio of 2:1 everywhere. I found it to bee too runny. My ratio was more of a 2:3 or 1:1. The more rubbing alcohol you use, the stickier the dye will be.
4: To apply the stencil, I removed the backing on the contact paper. Then I laid it sticky-side-up, and set my disc face-down directly in the middle. I liked this technique since it prevents wrinkles.
I wrapped the contact paper all around my disc, then pressed out any bubbles around the open areas of the paper.
5: Using a paintbrush, I painted on the Rit dye. For a solid black, you want to wait about 15 minutes, then simply rinse it off. Be careful not to let it spill onto the back of the disc. Dry it, then remove the contact paper.
All done! With transparent discs, the black will be purplish when held in front of a light, but it looks like a nice solid black from most angles.
