yes - it's called ferrotyping. the gelatin is 'melted' somewhat over the mirror-finished stainless steel platen. It's usually EXTREMELY glossy - in a way that 'normal glossy' paper could never get by air-drying...
I've been playing around with one recently. Prints are glossy (think RC glossy) and they dry within minutes. I've been getting eggshelling on the prints since I don't have a releasing agent. I've been thinking of getting some Pakosol which I've heard is what is needed to get it to work.
Just found a snippet from www.wilhelm-research.com-DarrenKodak Print Flattener, Pako Pakosol, and other hygroscopic print flatteners for fibre-base prints should be strictly avoided because such products can promote fungus growth in humid environments
You need to keep some weight on the prints as they dry, or pressure, as applied by the cloth apron of many dryers to avoid the eggshelling. You don't want the print popping off in small sections as it dries. Yes, the Pakosol, or other agents can "help" the gloss, but you will continue to get eggshelling unless you restrain the print during the drying process. If you are just using ferrotype plates, rather than a heated dryer with a cloth apron, you could put blotter paper over the print then books on top. If you ARE using a heated dryer with a cloth apron, you need to make sure that the apron applies some pressure to the print to hold it tight against the surface of the dryer until completely dry.
Gene is correct, the ferrotyping plate is very smooth and the wet emulsion picks that up when drying. (Along with all scratches or imperfections in the ferrotyping chrome.) You can squeegee a wet print onto a ferrotyping plate and it will dry with the high gloss, though it will have concentric rings since the outside edges seem to dry sooner. Ferrotyping was the classic way everybody finished their prints when I was starting my non-career working for newspapers. Since nobody cared much about archival prints the canvas on the dryers tended to get hypo-soaked and soon stained the prints a little yellow and smelled while doing so. I remember it was hard to get a good EVEN gloss with this process and I have not missed doing it.
Some of those print driers are not meant to be used for ferrotyping. I have one. Want it? A good Ferrotype plate is absolutely smooth and shiny as a mirror. It's extremely important to make sure the plate is spotless and polished. At one time, there was a product available for "waxing" the plate. Special Ferrotype plate polish was also available. When done properly, the print will release itself from the plate when it's dry. You need to place the squeegeed wet print onto the plate, use a paper towel to remove as much moisture as possible from the back, then roll the print firmly into contact with the plate. The print will lift from the plate as it dries. No heat or weight necessary. Personally, I like the look of Ilford fiber glossy paper without ferrotyping it. The surface has a look and feel almost like fine to grain leather.
Years ago when in college I was approached by a wrestling coach who was writing a book. He had 500+ 35mm negs that he needed 5x7 glossies of to pick the best for publication. The turn around time was 1 week. I had my own darkroom and a small Arkay drier so I took on the project. Almost all the prints came out with a great gloss with very few needing to be reprinted. The drier held 4 5x7 prints on each side with a drying time of about 4 minutes. He was pleased with the project and I came away with a good sense of accomplishment. I still do glossies for those that want it but most nowadays prefer glossy paper dried without ferrotyping. Once you get the hang of it it's not difficult.
Thanks for all the info. I agree that the look of illford glossy fiber paper is glossy enough for me. But we are bidding on a job and they have a very particular list of what they want. Shot on 4x5 film, Fiber paper, double fixed, hypoed, and very glossy. that is why I was looking into this. Souds like if we get it and go this route I better do some testing.
Thanks, Rich
