I've been using the HP Pro Satin for years and the weight, surface, and gamut is perfect for this printer.
However, as you can easily see on the Aardenburg fade test results with samples some of us submitted, that the white paper base is using some kind of oba that is not holding up very well.
So, after I got my Canon I started using the Canon Heavyweight Satin and I really love this paper and the fade tests show it holding up quite well. Its slightly heavier than the HP Pro Satin. It has a nice base color to it, not the strange cyan color of the HP ID Satin. And, like Pro Satin it doesn't have the logo on the back.
It has a texture similar to the old Kodak N surface, which is very slightly textured but not that horrible pebbly texture of Epson Luster. The gaumt and sharpness are great.
Definitely try this one out. Its a quality paper for the price. The only downside it they make it in 42" rolls. Why? You got me. That makes no sense whatsoever but I live with it.
The Epson lustre is very close. Is there a better paper for the Z3200?
