The problems with using an inkjet seems to be clogging
the head as well as wetting out the copper with the
ink.

I thought that using photoresist as the "ink" then
curing it with UV, might be a solution. That would
take care of the 'wetting out' and adhesion to the
copper problem. Just never had a chance to try it

I've been successful with toner transfer with a
laminator, but think inkjet printing would be neat.
