As far as I know it's partly what J&C does in companionship with Fotoimpex. It is also what MACO, Bergger and several others do.Originally Posted by chuck94022
Fotokemika does a lot of that work (think EFKE/ADOX and RolleiR3), as does Forte. There is also Slavich in the FSU who will coat any emulsion on any substrate, if the order is large enough. If you want 20x24" orthopanchromatic glass plates, they're the ones to ask.
