UV Plotter?
Take a look at http://www.megaelect.demon.co.uk/plotting_systems.html
But... not cheap 2000 Pounds !!!

I was thinking in hacking my deskjet to feed a board instead of the paper,
then print directly to the pre-sensitive board and expose to UV.
I guess that the board must have some kind of 'texture' to hold the ink in
place
maybe 'sugar and water' ?
With this method I think we can achieve a good resolution with standard ink.
Humm!!! eBay... :)
