I've been going through my stack of crappy, unused DX discs whenever I'm working on a better dye and trying to get something to work for DX. I have gotten a orange viking pitch black and this Orc black as well (shapes are scraps from the dye I was working on).
The dye has taken really well for DX, but there's just one problem. To get it to set good, I've been experimenting with additional heat, and it works, to a point. It tends to warp the disc (the viking became a poppy-top). There has got to be threshold where it's enough heat to set the dye, but not enough to do any DX disfiguration. Still working on this part, but it's a start.
