Canson Infinity Baryta and the R2880

[Ernst Dinkla]

Does anyone know if Canson Baryta Photographique is OBA free? It does not appear to be, from what I can gather on the website (i.e. they do not state it is OBA free, like they do with other papers).

Terry.

The paper white spectral curve suggest as little OBA as Photorag Baryta has and that isn't much.

Edit: Sorry, I think I made a mistake. I thought it was the Canson Platine and the curve in the review of that paper. See a bit older thread on that Canson paper. Don't know if the Canson Baryta is the same.

A 16 grams layer of Barium Sulphate makes the whiteness.
You may call that an OBA, but not the sort we usually talk about, because it has been used
through the history of b/w photography successfully.

Whitening agents like TiO2 or Barium Sulfate are not OBAs, I have not seen fluorescence mentioned as a characteristic.

That's true. I don't see any reaction with my UV-light detector on papers containing BariumSulphate or TitaniumDioxid.

I have just gone through my first two 25 sheet boxes of the Baryta Photographique now. I still really like the results, and I plan to use this a lot more. It appears a little sharper than the Harman FB Al to me, BUT I often got only so-so results via LightRoom with print sharpening ON (low, glossy) with the Harman paper, but much better results with it ON with the Canson paper.

As a note, check your paper carefully before printing. I had one box with 20/25 sheets defective. Under good light at the right angle, I could see a very thin, very straight line imprinted into the paper. I'm not sure what the cause is, but it does show up more when printed on (I tried it anyway as a test of that and a few other settings). None of my other boxes show this, so it's hopefully not too consistent of a problem out of the factory. That said, another thread here mentions something that sounds suspiciously similar with some of the Ilford GFS paper.

My results show their canned profile to be very good, though others may not find it as good(?). I use a 3800 printer with "wider" platen gap, and paper thickness set to 4 to prevent head strikes.
