Okay, I see the point about speed and repeatability being good
motivation to re-invent the wheel on making PCB boards.

What about an alternate use for the inkjet system?

If for example you put a hypothetical two-part etchant in the cyan
and yellow ink tanks, then printed the negative areas in green, you
could print the etchant right on the PCB.


I speak with the wisdom of ignorance: I don't know what the various
etchants are, so I am free from all those pesky details.

The great thing, of course, would be printing a catalyst solution on
the board, so that when you drop it in the etchant those areas etch
faster.
