I have been testing the paper also and Kerik is on target with his comments. The paper dries nice and easy and flattens beautifully. It clears very quickly and that is a nice feature in platinum and Ziatype both.
One nice surprise came when I was testing the first batch. The friend who got it for me (Richard Prehn, Zxorb) thought it was a digital printing paper specifically designed for inkjet printing of scans of platinum prints. So... I bit the bullet and scanned and printed some of my pt/pd and Ziatypes using the Epson 2400 and both color as well as monochrome inksets. Very nice results. A number who viewed these side by side with the pt/pd originals had a hard time telling them apart. It appears the paper will serve a dual purpose. The pt/pd originals can be matched well with digital prints. Nice and clean and sure cuts down on having to stock so many papers when you are printing with both methods.
The surface is clean and smooth and does show detail well. I was worried about it being lighter in weight than I am used to but have had no tearing or deforming during wet handling. I left a few prints in the rinse overnight and still had no troubles, though it isn't recommended.
All in all a really nice paper and one I will work with.
John is also a good guy and listens to feedback and does respond by following up on it. It is nice to deal with a guy who does what he says and becomes a partner in the process rather than just a supplier.
Just curious - what is the watermark situation with this paper?
Several months ago, my wife and I visited the Cranes Museum in Dalton, MA. After watching the videos, they gave us a couple of sample pads of writing paper - as far as I can tell, the same stuff known in the Pt/Pd world as 32# "kid finish pearl". I've been using it to do 4x5 contact prints, but it has a watermark that seems to always get in the way of the image.
