Pierre,
Your experience with toner and acetone is completely different from mine.
With my HP laser printer, the toner turns to liquid when hit with acetone.
Best of luck with the Toshiba toner. I sure hope you can get this to work!

Well, I tried plating with Copper. The results were not as good as I'd
hoped.

I think the problem is actually the toner (or possibly the parchment)
that I used. I did the thermal transfer at low temperature on the
kitchen stove, using a silicone spatula to smooth it on. The toner
did not come off of the parchment very cleanly... Plenty transferred,
but the picture was still clearly bonded to the parchment as well. I
would expect better masking if I can get more of the toner to transfer
over.
I used a strong, but not super-saturated solution of copper sulphate.
It plates the steel sheet in about 3 seconds, just by brushing it on,
and moving the puddle around. The toner seems to be insoluble in
acetone, and is actually fairly difficult to scrub off.
Unfortunately, it is permeable to the copper sulphate, so wherever I
rubbed it off, there was copper underneath. I'm not sure if this is a
property of the Samsung toner though. I'm going to try using a
Toshiba photocopier next time.
