Won't necessarily be everyones' experience, but Canson Platine and my Epson 4900 didn't play well together. The sheet paper had just enough curl to require vigilance that it successfully came through the paper path and after half a dozen sheets deposited enough particulates to require extensive print head cleanings taking over an hour and I'm sure quite a bit of ink to clean it all up. Won't be using that again. And it really has no practical advantage over GFS - for thoswe to whom the appearance of the photograph is more important than the feel of the backing.
This experience I believe is due to Canson's move of switching mills, and it's a terrible decision. I have also noticed this on Platine, but not the Baryta. I was using all Canson Platine from lots prior to mid 2014 until about 3 weeks ago. The new paper does have an issue with particulates, and this becomes even worse if you cut it without a coating of print shield. as all the particulates spread to the printed surface and can become hard to remove.
I had noticed a total change in the Baryta with my last purchase, less overall glossy surface, but that was OK.
The Platine looks the same, but it has the particulate issue. When you unwrap the roll (Platine is wrapped in a protective wrapper), you can see the stuff coming off.
As Mark mentioned this is nightmare for head clogs.
As for Canson, I fail to understand companies like this, as they had an award winning paper, that had been given a total 100% approval from Bill Atkinson. Then they change mills or formulation or both, and don't do a good QA on the new product.
I am going to have to reach out to Canson when I free up a bit of time as it's too late to return the rolls to the distributor.
I have also moved back to M Silver Rag for now until I can get an answer from Canson on the situation of Platine.
