    Dynacolor (here in Rochester) made a Kodachrome compatible film, and in the early '60s, DuPont had a Kodachrome project, but the introduction of Kodachrome II killed it if I remember correctly.

    Kodak released the patent for K14 so that anyone could do it. At that time, Fuji Konica and Kodak could run the "old" Kodachrome. All declined to move into K14 and thus Kodak was the only source of K14 films. Dyanchrome was long gone at that time.

    The problem is not with developing this film. That is fairly easy compared to restarting its nmanufacture. Do any of the old coating machines still exist? Is there anyone with the expertise to run one? I seriously doubt that any company would be willing to make Kodachrome film again. If anyone truly believes that such an event could happen then I have some land in south Florida I'd like to sell them.

    You do not need the old coating machines. Any current multi-layer coater would be fine.
    Out of those 8 companies only Kodak went on even in the haydays. And Kodak profited for a part from the reputation of the tradename Kodachrome.

    Some time ago a fellow member wanted a custom production done. He was fixed at Kodak, but Kodak was not interested. I don't assume there is still someone else considering custom production.

    I am not so sure about this. Kodakchrome contained more layers than any film manufactured today.

    Gerald, Kodachrome was no wonder-film.

    The main difference I see between a B&W pan film, and a (basic) Kodachrome-type film, is the yellow filter, and separation of spectral bandwidths (red, green, blue, etc) into different emulsion layers and never mixed.

    What you need is not the old coating machines, but a coating machine that can manufacture in small enough batches that you don't have $1,000,000 worth of perishable product that you need to unload in a short period of time. I'm thinking a master that is 140mm wide (just over 5½ inches) and maybe 100m long (just over 328 feet) this would allow for trimming into 35mm, 120, 4x5 sheets and 5x7 sheets. It would be a little thick for 120, but you could use the same thickness for 35mm, 4x5 and 5x7....

    Modern coating machines can be reduced in coating width. But the speed is another factor. Depending on coating technology there is a limited speed range. And with short strips to be coated these must be brought up to speed before coating starts. And the volumes of tubings, the machine rig-up time, cleaning, the preparation of needed elements not availabable off the shelf, necessary pilote runs..., all must be taken into account.

    But as you indicated, it is not an issue of technology and still(!) not an issue of competence, but an issue of economics.

    What you need is not the old coating machines, but a (new) coating machine that can manufacture in small enough batches that you don't have $1,000,000 worth of perishable product
    This is really the key to film manufacture in the future. We don't really want 54 inch 6000 foot master rolls, we need something more like 24 inch 600 foot master rolls. What's really needed is new machinery designed to produce at this type of scale and the flexibility to make many types of film product on demand. That's an engineering problem that can be solved given the proper minds applied to the task. What we do not seem to have is anyone willing to invest in it. A "right-sized" machine producing at that scale could be kept busy enough to offset it's costs.

    ADOX appears to be headed in this direction, although I don't know that they have scaled themselves up to having their own coating facilities. Rather, IIRC, they have the actual coating done by an outside party that coats many things. But their scale of production seems on track to me.

    Someone at Kodak had dropped hints of capabilities along these lines but apparently that went nowhere.

    Of course, if such a coating faciilty could be shared for other applications that enhances it's appeal.
    All this has happened before, and all this will happen again.
