On the question of banding or stripes on lith film I recently experienced
this problem with Maco Genius film. Tray wise no change and same dev but
banding occurred with some but not all sheets which suggested a problem with
manufacture rather than processing or trays. Can't comment on Bergger films
which I have used in the past with no problems but perhaps they have changed
a few things.
Utimately it is these struggles with conventional materials that is fuelling
an exploration of digital negatives....
