In order to answere your problem I would approach it from an aspect of elimination.
1.Do I bulk load myself: Yes) Probable cause a) Grit in loader or b) Grit in reloadable cassette.
Do I bulk load: No-then go to 2.
2. When I remove film from my camera do I return exposed film to its container or do I put it into my pocket( another probable means of contamination .
3. How about the Photo.Lab.do they leave the film in its container when it is handed in for processing, or do they remove the film and place it into a bag for future processing.
Having eliminated all the above probable causes of (Black tramlines appearing on your prints, with of course duplicate scratches on the negatives) the only conclusion that I can come to is that the Processor at your lab is faulty or that the film is being pulled out of the cassette instead of their breaking the cassette open before processing.
This all with the understanding that there is indeed physical scratching on the negatives themselves.
As to the light leak and introduction of "sponges".can I assume the sponges are intended to excert more pressure on the pressure plate which has the possibility of scratching further. If the pressure was too little, would not there possibly be flare around each exposure, not scratches.
If sponges where ment to exclude light from the camera back, would there not be patches of Flare not scratches?.(i.e. Tramlines are an age old name for longtitudinal lines produced by foreign matter abrading film. (this is for Luther's edification) Coops,
"Add a Sponge" what's that??
