Lots of medias have optical brighteners in/on the surface. For setting up digital proofing systems this is undesirable. The way we test for it is to simply shine a black light on it. The more of these optical brighteners, the more it glows.

Maybe you can get with your media supplier and bring a small black light. The ink inhibits it though. So all that will glow will be the paper. You'll have to make your design to accomodate this; think of it like a negative.

Sounds like a fun project. Enjoy.
