Homebrew PCBs

OK, since I started this thread, I have now read the 100 or so posts
on the subject (a bit late, since I was in the hospital for 6 days),
and I have condensed the information to send it to my friend with the
Epson pigment-based printer.

I will recommend that he prepare a board properly, print and dry the
board, and report back with results.  I will also get the specific
information on which model Epson he is using, and the ink cartridge
info as well.

I've left my original post and Stefan's reply unedited as a
benchmark/reminder of how the thread started.

Regards,
Ted
