I actually did give this a try. The backing has a super slick waxy finish and at a glance looks perfect for the application. However, it was so slick the toner wouldn't adhere to it. There were traces of it on the backing, but the rest was on the paper I had taped the backing to...like it remained on the drum until something it could adhere to came by. Anyway, at least for the stuff I had, no joy!
I just tried the vinyl again, but with an iron this time. This is the vinyl that "bled" so badly when I ran it through the laminator. I had the vinyl stuck to a piece of 81/2 x 11 printer paper (to go through the printer) and I had the iron set to the highest setting. I applied heat with only moderate pressure for 180 seconds, and then put the paper + vinyl in the freezer for 30 minutes. This resulted in about 95% transfer...some traces and pads didn't stick to the pcb, but no bleed at all. This leads me to think that the bleed is in fact from too much roller pressure in the laminator. I am not going to see if I can modify the laminator to give me less pressure on 0.064 pcb's.

Have you tried using the backing? Remove the vinyl, and print onto the slippery side of the backing, then press than onto the PCB.

Surprisingly, it actually worked better than anything I've tried so far in transferring the toner to the pcb, 100% every single time. The only problem I see is that, the toner seems to mash and spread out when it goes through laminator, making the tracks wider with uneven edges. I think because of the compressability of the vinyl, but it could also be the heat making it bleed. I haven't tried using an iron to see if it yields the same results.
