Anybody tried this ink?
http://www.hexionchem.com/Products/Main.aspx?id=3630looks like 'Hexijet' and 'Hexilok' might be worth a try.
They are UV curable resin based inks.
note that they have White!
I tried to email them, via the website, but it was rejected as
undeliverable. Maybe someone local could call them (I'm in Australia)
I rang Hexion Australia but they don't handle any of the inks here.
They told me that the Hexium inks division is being sold off to
Collins Inks (Ohio). I'm waiting on a reply from an email.
Also, I found some inkjet inks that are made especially made for PCBs
