If there is some kind of two part epoxy that has a 'thin' (like ink)
liquid part and a water
soluble solid fixer (Or vice versa). Dip the board in a solution of the
fixer, then bake it to
dry it and inkjet the actual epoxy onto the hardener. Once the epoxy is
cured, you wash
off the rest of the fixer. Etch the board and then try and figure out
how to get the epoxy
off with out taking the remaining copper with it :-) If you find an
epoxy that only binds
so-so with copper, you might be able to just peel it off.
