I used to do them for Microwave panels. Ran them on a progress cylylnder press using conductive ink . I cant be much help other than the ink is like 4k a gallon
Haha yeah that would be printing the conductive stuff directly. What I'm looking at is printing an etch resist
on copper clad boards, etching, then removing the resist.
Apparently for small runs any lacquer ink will do, and can be removed with xylene after etching.
Same lacquer ink can be used to print component guides/labels on the board once complete.
