I dunno, i use a 10W car light shining down from the drill, from the side
and from behind. It makes the copper glare a bit and after a while my eyes
get tired from it and it looks too much like the epoxy around it. Not so
that i wouldn't see it but enough to stress my eyes much more than the
black.
Also, if i don't hit the exact center, the drill nicks the toner exposing
a bit of copper, so i can correct the position slightly to get it on
target.
