Just use inkjet photo paper. It is the easiest, cheapest option people
have found.
Several coatings were tried, starch and stuff, i do not remember how those
turned out exactly (not spectacular or i would remember). I personally
have very good results with high temperature silicone, but there is a
problem, the result will "etch through" in places. I do not know why, but
one reason may be that the silicone does not add any paper residue, like
the papers do. It is great for component legend though because it leaves a
jet black toner image with no annoying grey residue, and of course you can
just pull it off the PCB without any water involved (you can even re-use
it if you like).
Anyway, the coatings are interesting and all, but nothing (i know of) was
found that delivers better results than inkjet papers.
