I still think that where there is a niche market someone will step in. The biggest problem is how to scale down film and paper production from the massive machinery and runs required. I have been saying for years the technology behind ink jet coatings will be the way to go. Ink jets are now coating thin film solar panels with perfect uniformity, they are even layer by layer printing out human organs. These capabilities should mean that film and paper formulas could be laid down on materials with perfect uniformity. Films and papers could be made to order in very small runs. It seems the same ink jet spray tech that can coat solar could be adapted to lay down emulsion. I hope someone experiments with this in the near future.
