Homebrew PCBs

Hi
 I'm new here (not a lurker), but I'm actually looking into two
things right now, and a backup for them.  If any of you have any
information on them, or know where I can get information, I'd
appreciate it.

A company Xeaia or something like that has conductive inks for inkjet
printers. If this works, and you can get an insulating ink as well,
you can build circuits by printing them on your inkjet. I have not
heard back from them yet, so I don't know if they are interested in
our market, or if they require proprietary printers.

and I'm trying to find out if anyone makes a screen printer mask
inkjet ink, so that a negative of the circuit can be printed right
onto the  screen, and then to build up (additive construction) the
circuits using conductive inks or pastes using screen printing

If none of these work, I heard (at least 3 or 4 years ago) about a
techniques where you print the negative right onto a fiberglass sheet,
then squeegee the conductive paste into it.  Additional layers for
vias  are built up by printing toner over areas where you don't wan't
through holes, printing another layer that is a negative oof the vias
and putting more conductor over it.

Sounded interesting, fairly easy, clean and doesn't waste anything (but
toner).  But I never heard anything else about it, never owned a laser
printer (only inkjets), and don't know anyone who tried it.

Again, any information would be appreciated.
Thanks,
Richard

FYI,
  So far, no joy on emulsion inks for inkjet printers.
