Thanks Andrew and Matt,
I've seen the paint process, and was hoping to find an alternate material.
Nothing against paint, it's cheap and easy, but can be a tad on the messy
side. There also seems to be a widespread want of something better, but I
haven't seen any solutions yet (still digging).

Like Matthew, I don't have any direct experience, but there are documented
tutorials online of this working very well...I think the one I watched even
concerned an Epilog, using some common form of black paint.
I recall it being important to configure the tool path for the laser to
start on the end of the board that was furthest from the vacuum outlet of
the cutting area, and then working towards it. This was to prevent the
vaporized paint particles from redepositing on the already-exposed parts of
the board.
Lucky you for having access to such a powerful tool...I love to hear how it
works out!
