Strange Pattern on Film

Dear All,

the manufacture of 120 Film wrapper is INCREDIBLY complex and is a very high tech coated product and has to perform many functions.

I think the poster said it only appeared on three frames, this indicates the film was 'off the roll' in the back of the camera, it also seems to have some 'flair', my initial thoughts is that light has leaked into the camera somehow, but I cannot be 100% without seeing the film.

Simon,

For your reference, another roll from this brick has the lot # of 91CTM1C01/01 with an expiration date of April 2015.

Regards,

RM

If these frame numbers did not exist then all but 2 of my MF cameras would be useless as they are all red window cameras, so that is why the frame numbers are printed on the backing paper, saying this, in over 8 years of using red windows with Ilford.Kodak and Foma film I have never come across this problem, and I am not that careful closing the window cover, I can only think that the film somehow would loose, I have used these Fuji cameras and I have had the odd lose wound roll, as to what the results were I couldn't say as I would tend to throw away the roll as not worth the time and chemicals to develop on an off chance, but were I live, Jersey is just 45 sq miles, it is very easy to re shoot the film

Two strange things I notice: (1) in the first image, the pattern appears twice, in the upper-left and upper-right, and the upper-right image is smaller. (2) The pattern appears twice in the second image as well, the second being the same size as the first, but fainter and directly under the first.
If these were backing-transfers, how could they be different sizes? I have no idea...

The pattern is actually four rings of successively larger diameter leading to the number, so there could be multiple sizes of the ring of dots. If it's transfer from the printing, roll diameter could affect position; if it's a light leak even more variables are possible.

There is an image on the first page of this thread showing some rollfilm backing paper (which originally came from me, posted in response to questions about frame number locations) that shows the pattern for FP4+. The original reason for that was to show that some makers do not have the lead-in patterns on all number rows -- now I wonder if Fuji cuts back to reduce the possible transfers!

Dear Ratty Mouse,

Thanks : We have no QC's against this batch number 91CTM of any type ( manufactured Week 1 April 2012 ).

Kindest Regards

Was the in the fridge or freezer? To me this issue, and I've had it with cheaper films is more likely a moisture problem then light leak.

My film dealer does not store Delta 400 in the fridge and I use this film up in a matter of weeks, so I keep it at room temperature as well.
