The idea I floated would not use a positive. That's just the name of the film I used -- Kodak "fine grain positive film" #7302. The point would be to allow the inkjet printer to make a positive print on film so that the small dots would be in the highlights. Then use a negative film that is easy to tray develop under a safelight to make the final film for exposing the alt-process final print.
I used the 8x10 film as an intermediary for flatbed scanning before Nikon released its Coolscan 8000. I enlarged medium format film onto the 8x10 and then scanned with a flatbed with transparency adapter. It produced a huge number of pixels and also resolution, but the image quality was a bit below the Nikon 8000.

Not all films are suitable for reversal processing, preference to slow films.Also, though the description is accurate & simple, finding correct exposure (may not be the regular film speed) and development times requires trials.If anyone interested I can supply several notes I have on the process, but it is at least 10 years since I did any.Jim ThyerSent: Thursday, January 29, 2015 8:58 AMSubject: Re: [QuadtoneRIP] Re: Ink limit low limitI believe that any silver based film can be developed as a positive. You just develop normally, bleach the silver, re-expose, and then redevelop and finally fix though that final fix should not be necessary as there should be no silver halide left.Harvey
