In an earlier thread I mentioned I had bought a cheap part-roll of Fuji Crystal Archive paper.

I tested the paper today and although it appears to be useable, the whites are not as bright as they should be. Processing an unexposed strip gives a result that looks off-white when compared to a new batch of paper. I have had this problem in the past with paper that is a few months old.

I was wondering if using a print brightener such as Fotospeed CPS100 would help with old paper?
