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
