(A bit off the OP)

They talk about "....The exceptional smooth white tone is achieved during manufacturing by introducing natural minerals to the process."
What that's supposed to mean.

Yes I know, but the quotation was from the info for a matte cotton rag. Not the Baryta or Platine.

TiO2 is very common in paper too. There are blends of TiO2 with other whitening agents to get a better price/performance. Kaolin is used as a cheap whitening agent and creates a smoother surface. The cat litter like stuff to trap the inkjet inks are minerals. Called micro ceramics and other fancy names.
Canson probably used more expensive whiteners for the Rag Photographique and asks a price for it. Not all Canson papers are at that level and not all have their origin at Canson, so some papers are overpriced there. Moab Entrada Natural shows an almost identical spectral plot to the Rag Photographique, use of good whitening agents and no FBAs. At a nice price.


met vriendelijke groeten, Ernst
