I've just been looking at that Avecia Jetrack ink jet resist, and am waiting
for Xaar to get back to me about a suitable piezo printhead. I'm not sure if
an Epson print head would work, as they are designed for aqueous ink,
although it might be worth trying.
To get accurate positioning of the printhead, I would think that some sort
of X-Y table would be required, or something much simpler and cheaper can be
built using polar co-ordinates, involving a rotating table.
I'll keep the group informed.
