That's very interesting news.
I see a problem with alignment of two-sided there, but i reckon some holes
solve that nicely.
I'm not sure about the charge though, i don't think it will be there with
a foil, even if isolated on top. But apparently there's still enough toner.
Have you etched already? I have fantastic looking transfers with silicone
paper that don't stand up well to etchant.
Do me a favour and check with a multimeter if it is conductive at the
surface, use the round sides of probes or plugs so the points don't go
through the surface.
