expose the Photoresist coating on a Presensitised PCB as I have a
small XY table that would be suitable for such a CNC venture, I was
looking at Duponts website and they talk about a UV Argon Laser for
LBI ...if the price was right it would be the ultimate Homebrew
PCB'ers dream

The toner is transfered to the drum inside the laser and then to the
paper. the toner is moved and held in place with a slight electrical
charge. The copper of the board would stop the process.
But... there may be a way to cover the board with a non-conducting
film and print on that.
In my opnion, the best chance we have of a direct print is ink-jet.
They already make ink-jet printers for printing on things like belts
and hoses and metals and boxes.
It seems that we have just not found a good combination of printhead
and ink.
