A paint that gives off no UV fluorescence or infrared light would be identifiable on most cards, because it would differ from the card. It would appear as a black splotch on that Old Judge.
Trying to get the perfect UV fluorescence, IR emission and visible qualities (color, texture, etc) in a paint is like trying to get a football player to simultaneously be a great NFL offensive lineman, passing quarterback and corner back. It's safe to say it can't be done, and you'd be a fool to even try. Adding the needed 160 offensive lineman pounds to your star cornerback turns him into a bad cornerback, and similar happens when you tinker with the paint qualities.
