Sure it would.  It blocks all light except UV so different inks show up differently.  They use this in forensic document examination.

I don't know if your serious or joking...  I am so confused... I think I'll have to look this up.. Damn you kav making me do some research on if blue sharpies would block the UV light

I remember seeing that video a while back its cool if your at a rave I guess but I don't think that would really detect colour touch.

ok well I was reading an article about it

and it kind of works to a certain degree now with it catching Colour touch on a comic I guess we will have to see if anyone has had luck with that or if I find a book and can test this out.

I drink UV chemicals, and then pee on the book.  Works every time.

It's why I love buying books from you.  Such an intoxicating aroma when you read through it the first time.
