Halogen lights also work very good with black ink. Black lights are more for detecting modern color inks that some hack put on a card.
EDIT: A lot of times you can take a 1200dpi or better scan of the area in question. I then put that image on my TV. You can turn centimeters on a card to feet on the big TVs everyone has now.
