for the paper detection...
on normal daylight conditions, the security fluorescent pigment powders are virtually invisible on paper. However, on exposure to UVA (365nm, black light), UVB (300 nm), or UVC (254 nm) the unique fluorescence colour becomes visible. LuminoChem pigment powders are highly effective special additives for coding and marking purposes (e.g. usage in security printing). Possible application fields are high quality, solvent-free or solvent-containing special security printing Inks and lacquers with very good light fastness on plastic and on paper surfaces.

Having read this I believed it was extremely informative.
I appreciate you finding the time and energy to put this informative article together.
I once again find myself spending way too much time both reading and posting comments.
But so what, it was still worth it!
