Digital BW, The Print

I held Entrada Natural paper under my fluorescent UV light, next to
PremierArt Fine Art Hot Press (the non-OBA version) and PermaJet Alpha (no
OBA paper).  It appears to me that the Entrada Natural may contain a small
amount of brighteners.

 

Is there another test for these?

 

Could someone verify this?
