Good evening Mohamad,
Some good results were achieved with the MISPRO inks
<http://www.inksuppl y.com/arcink_ mispro.cfm>, the yellow color
performed best.
As far as i know only piezo type printheads will work.
The important thing is you need to cure this ink with heat after
printing (for example in an oven or on a heated metal plate). The ink
will darken during this process. The cured ink is VERY tough and will
stand up to HCL just fine. Without curing, it won't resist the
etchant.
Another big challenge is to get good 100% coverage on the copper. The
ink drops must form a closed surface, no gaps or holes. On paper this
does not matter. It can help to wipe the surface of the copper with
car break fluid or propylene glycol, this acts as a wetting agent.
Also you will have to play with the printer settings to get the best
results.
You will have to try. Possibly with your printers you could also use
more advanced inks that do not need curing, or maybe UV curing inks.
But the MISPRO yellow will give you a starting point.

The idea of board printing (to make a circuit) came to our mind because we believe that the process of tshirt printing is the same as board printing. Our printer can print on any kind of surface like garment, glass, textile, wood, board etc.
