She has tried a black light, but it did not help.

Vonnie--this is something that works with many similar situations. I scan
the image, in color even if it appears to be a basic black/white thing.
Then use the color spectrum toggle thing (or whatever that feature is
called!) until you find a color band that can highlight the distinction
between the two colors and then focus on enhancing the contrast. You may
need to play around with this a bit, but I've always found digital graphics
enhancement can go a really long way with "bringing ou" faint images. Btw,
sometimes it can take awhile so always keep the original scan and work just
with a copy of the scan, in case you need to "back up" and try a different
band of color.
I hope I've explained this adequately!
