Digital BW, The Print

FWIW, http://www.wilhelm-research.com/epson/R1800.html lists Epson Premium
Semigloss Photo Paper as having no OBA, and Epson Premium Luster Photo Paper
as yes.
It seems odd that they would both glow a similar amount under black light.
Does anyone have an idea why that is?

Best regards,
John Moody

That's a good question .. seems to be several observations about that paper.
In any case, it's not over-the-top white. Maybe Joe can examine a piece
with the big spectro and let us know what it does near the UV region?

Best regards,

Ok...help me out here.....one of you says there are no OBAs, and the other
says there are. Which is it?
