That's what, 1.5mm? (I'll never understand how you guys manage to think in  
16th of something ;-) That shouldn't just "vanish" even in a very strong  
etchant.
Do you have a picture or something of the transfer? It must be a real  
solid layer of toner.

You can try to transfer on the now blank PCB again, then hold against  
light and look if you can see through the toner. Since there's no copper  
you'll see the toner density.
