I did it !
I e-mailed several kodak product managers to explain them my point of view. Just I told them that their pricing policy for LF film looks good if they are to close, but if not a better choice it would be expanding the customer base with a popular pricing.
Of course I got no answer from them...
Drew, just read (if you haven't) Making Kodak Film book. Another interesting book for you is "Innovating Out of Crisis: How Fujifilm Survived (and Thrived) As Its Core Business Was Vanishing"
Just read those two books...
There is no minimum roll length, you can coat 1m if you want. Auxiliary/Reusable film bands can be used for leading and trailing the coated section. Of course a manufacturer will decide what is the most cost effective coating batch depending on consumption, financial cost of having the manufactured product in the cold store, initial manpower (etc) for each batch...
I was speaking about another thing, coating machinery has rollers to guide film transport, some (sheet) film may have a minimum transport roller diameter to not bend it too much inside the machine. Just speculating that some coating machines may not be able to coat some thick sheet film.
kodak was coating sheets in a different machine/place than rolls, IIRC. This is an speculation: I see little factors that won't allow to coat sheet film in a machine that is coating roll film, the single one I can guess is diameters of rollers in the transport system across drying, etc
Some people at Kodak (IIRC) complained that ilford had a more flexible manufacturing facility, as they had machinery that was designed to be efficient for the mass production days... not for today's low scale production.
Yes, I've to check it better but my preliminary tests show that the base it's blocking UV, as others have said in this forum.
