Plate Coating

Post by JohnFP »

I would not like anyone to disclose any proprietary information. Can you tell me how they coat glass plates, just which method. Dip, flow, pull rod or spray. Do they coat huge sheets and then cut to size? I would love to know how the mass producers are doing it. Again I do not want any proprietary information just the method if that is available to the public.By the way, has anyone tried to spray DCG on plates? What were the pro and cons of that method?

The emulsion is coat to glass plate by narrow flow via thin crack for batch production. The glass plates go one after another on the conveyor. Such method use in "Slavich" plant (http://www.slavich.ru) for making silver-halide photoplate PFG-03 and DCG photoplate PFG-04.
For laboratory conditions you can pour emulsion from a glass to the middle of a warm glass plate and wait, while it spread on all surface of plate. Many defects of photoplate can be for such method.
