I have sent staedtler an email asking if they have an ink for an 
piezo ink printer that i can print on printed curcuit board with a 
flat bed printer and stay on during the etch. we will see if they 
respond.
i have new ink carts ordered, while i am waiting for them to come in 
i am toying with FUTURE floor finish, its the acrylic liquid made by 
S.C Johnson. put some small marks on a pcb, will see how water proof 
it is when it drys. tryed mixing some higgins black india ink with it
(didnt work) also rit dye(didnt work). put some thin marks with food 
coloring(green) but has propalene glycol in it, will see if it is 
water proof if it drys.


1 hour later.

the marks i put on the pcb didnt wash off, even rubbed it with my 
finger under water,even the mixture with the food coloring with 
glycol in it dryed. its evening here now--will etch tomorrow and see 
if it holds up. if it does then will try to run it throught the print 
head, but will have to clean it after i am done with the printing 
because that stuff is tough.could not scrape it with my finger nail 
from the pcb.i cleaned the pcb with soap,water and steel wool, then 
cleaned it with windex before i put the marks on the board.
the future is kinda thin so i may have to put a piece of thin felt on 
the head park to keep it from draining out, also this may help to 
keep the head from drying. will try adding more food coloring(with 
glycol in it) to keep it from drying to fast. 

as stated in an earlier post, if any thing drys in the print head, 
its all over but the gnashing of teeth.

i may have to get the bubble jet printer back out to see how it would 
work for printing on pcb with future floor polish ;<).
