  Water based paints dissolve instantly in water if there's still a 
little water left, or not if they're completely dry.  And etchant rolls 
right off a fresh copper board, but sticks once the board has etched a 
little.  I'd imagine this has mostly to do with surface prep and drying 
the ink.  Could be a more resistant ink, but if it was some generic I'd 
doubt it..

  Of course, the great surface tension reducer is soap.  A thin film of 
soap on the board or a drop or two in the ink might go a long way for 
any ink working.  Could cause problems though, same things could easily 
affect etching or printing ability.  Should've kept a couple more of my 
old inkjets, but more than a few adds up to a lot of bulk.
