I have seen this....and once again I have checked with Technical Service, we have no complaints AT ALL recorded regarding this issue, but we did have this discussed last year when we had one last year
and examined the film.
I have asked Technical service to give me a possible cause and I will post it in due course.
As part of our QC procedures we process and expose and process on average 400 to 600 film samples per week, we have NEVER seen this issue....ever on our samples.
