Also, some say Peter Lik uses Fujiflex and some say he uses Crystal Archive Pearl. Know which one?
I've used Acrylite, Ultravue, and I think when we use 1/2", it's Lucite. the 1/2" stuff is all custom cut and the edges hand polished so it's whatever the supplier is using. My favorite face mount is
ArtGlass, which is amazingly clear, very good at reducing reflections, and is easier to work with than Museum Glass.
Peter Lik uses Fujiflex, as does Rodney Lough. There is a lot of confusion with Fuji papers because they are all "crystal archive", which refers to the emulsion technology and has nothing to do with the paper base. But if you have ever seen a Lik sales presentation, and someone asks about an image that isn't hanging in his gallery, the gallery has many of his images available rolled up and stored in tubes that can be quickly placed in a frame and shown in the sales room. A sales person brought one of those out and let me "look" at it and demonstrated how they did this, and it was definitely flex. I think some of the sales people just like throwing the word "pearl" in there, I've heard one of his people claim something like "the images look so good because they are made from pearlized silver crystals, suspended in a soft resin which is hardened after the image is created on it." nearly busted my gut LMAO.
Personally I've recently switched from FujiFlex to Ilfoflex. The two are virtually identical, with the Ilford product have a very subtle whiter base but prints compared side by side are indistinguishable. The Ilford is substantially less expensive, but in my case price isn't a factor unless all other things including quality are equal, which to me they are.
