Hi guys, I just finished testing several of the latest greatest inkjet papers, and my two personal faves were Ilford Gold Fibre Silk (a baryta paper) in first place, and the new Canson Platine Fibre Rag, which is not a baryta product, in second place.

The white point of the Canson paper is lower by a smidge, but otherwise the papers, surfaces, etc., are close enough that the difference is negligible to my eye.

So then, the question of archival stability. The Canson is an acid-free rag paper (the only one of the bunch), has no optical brighteners, and claims to be made "without chemical substances that contribute to premature deterioration."

Does anyone have any educated guesses as to how this compares archivally with the baryta papers, the Ilford in particular?
