black light / white vinyl - geek question

[DGDesigns]

I printed on Ritrama's Wall Walker "Fathead" material and left a 1/2" border around the design so it would glow when exposed to a black light. Everthing in the room that was white had a glow to it....EXCEPT the white vinyl !! Any ideas why the white vinyl doesn't work under black light conditions??

does any of the white area(s)? our blank digital media always looks a slight grey to me. good question though, do any white vinyls glow?

None of the white glows, but I also did not check any other materials. Just came home from the customer.

kinda curious if any white cutvinyl would glow. i haven't had a black light since college, so now i can't check. i mean what if... oracal, solex, shinerite, avery, arlon & ectz.

The glowing under black light is due to optical breighteners. I would guesss your media does not have much if any optical brighteners when made.
