Reading faded signature using enhanced light?

[kt4hx]

Thanks everyone for the responses. Lots of good info. I agree that if I had to buy a $25k machine to read them, I wouldn't want it. However, if a simple black or uv light will make some faint sigs identifiable, I'm good with that. I often look for those kind of balls because they are cheap, and I find the investigative part of it fun, because you never know what you might run across. Granted the value isn't there, but if I am not investing much, then I am good with it. With the cheap stuff, the fun is knowing the players held the ball to sign it, and that it might have been used in a game even. A simplistic view I know, but I find that fun collecting.

I would imagine that there is (or soon will be) a chemical that could be applied to the ball to restore the contrast so the signature was become easily visible. Has anyone experimented with this idea? Would that be considered acceptable since the signature isn't being altered?
