The problem could be the film. I experienced a problem with banding with Bergger BPF film when printing with UV processes. The bands do not show on the negative, and in fact don't scan, but when I print them with UV processes they are very prominent. This was 12X20 film developed with rotary processing in a drum. I considered the possibility that the method of development was the reason for the banding, but after a lot of thought concluded that the problem had to be in the film.
