How much knowledge to you have on ink formulations ? Its an entire
field
of expertise. Inkjet ink chemists are specialized people. You want
to
develop your own inkjet ink that gives high image quality AND can
also
forms a stable acid etch resist ? ! My best bet would search
and see if anyone else has done it.
The reason why everyone uses photoresists is because it works the
best.
The phototool is important, and I've only ever seen good ones
from an
inkjet./transparency, I've also seen many more bad ones from
various
inkjets and inkjet transparencies. Its important that the ink and
transparency are compatible with each other, otherwise you get pin
holes, banding and rough edges. The Epson stylus series do very
good job
with their dye based black inks on their transparency. Only problem
they
are expensive. I suspect Epson have patented their transparency
because
no one else make one the same. You can print on it then dunk it in
water
and nothing happens to the ink. There are other transparencies that
work
well with the Epson black ink. The HP inkjets use a pigment black
and do
not go so well on Epson transparencies. Use HP transparencies with
HP
ink, the results are quite ok.
I'm not looking for ink for an ink-jet, I am looking for ink that one
would use for silk-screen type printing.
Ink for printing with an ink-jet print head would be very thin. I am
looking for a nice thick almost paint like ink that is acid (etch)
resistant.
I have been reading more and more about a certain kind of etch resist
pen that uses a laquer based ink. Perhaps I will try some type of
laquer paint/ink.
I am also considering the photoresist method as it sounds like this
is the method of choice here.
I will start a new thread.
