Brad,
The Denatured Alcohol they sell in the hardware or home improvement stores for thinning shellac should do the job. It is a mixture of ethyl and methyl alcohols, and some other stuff that makes you very sick if you drink it.
I had little success with the mixture of alcohol and acetone. I tried several ratios, with poor results. I tried pure acetone, and got a very good transfer. The only problem was poor control. It was hard to tell when to stop the acetone soak before it toner ran all over the place. When I get a chance, I will try some ratios with high acetone.

I would like to try the cold method but have not had any luck, anywhere, finding ethyl alcohol. Only isopropyl.
I suspect toner is definitely a problem here. I’m using ‘compatible’ cartridges, so that only seems logical.

Subject: RE: [Homebrew_PCBs] First attempt at toner transfer
Almost all the problems I had with using the toner transfer method with a laminator was because of the toner.
With the original toner from two different printer brands worked well, but replacement toner cartridges did not work very well or not at all. One thing I found that helped was to run the blank board through several times to get it heated before I applied the paper with the image to be transferred. Once I switched to the cold method, I have not had a problem using any type of toner.
