When rolled up on the spool. the numbers and letters on the back of the 120 backing paper are pressed against the front (emulsion) of the next layer of film in the roll.-) the corresponding figure has no contact with the emulsion, but is divided from it by the base.
I’ll never trust Kodak again. And if I ever do use tmax again it will be in a secondary back.
I assume you mean the paper proper.It was backing paper, and required much testing to reveal the problem(s).
Did Kodak ever issue a recall? I only found out about this problem when I started developing the 20 odd rolls that I recently shot (most with beautiful numbers in the sky now). I bought them after this issue was already known, and as far as I can see, the affected batches are still being sold around here. If Kodak hasn't issued a recall, that is, I think, enough to distrust them.Fixing this problem was one of the most difficult problems Kodak has faced in years. It did not show up on any internal tests AFAIK and was only discovered after customers began seeing it. I'm just glad that the problem was fixed for the rest of the people who still had faith in them.

Rolled the film and paper together a bit and lo and behold. I have an alignment.
Image is where ink touches emulsion after it’s been shot and rolled on.
Three different affected rolls align this way.
I noticed the ink was hydrophobic. My theory is ink kept the emulsion “dry” while the backing paper around it acted like a sponge to moisture. The emulsion touching paper absorbed and released a little moisture over time into the emulsion making it softer, while the emulsion touching ink stayed relatively dry retaining its hardness.
I don’t know about other people, but I hold my face close to the Bessa II while composing and focusing. On a good walk my breath could introduce a lot of moisture to the unsealed camera.
Right, that’s what I meant. When it’s fresh, the backing paper of the upcoming frame(s) was touching the emulsion of the frame you are revealing. On the take-up side of the camera, the backing paper from the just finished shot(s) will roll under and touch the emulsion. The shift can be about two inches. The direction of the shift tells whether image formation occurred before or after camera exposure.Not the corresponding figures.
Letting even the flipping of figures aside, the location of a backing number somehow transferred to the emulsion side would be shifted in respect to its original position.
So just to be clear we are talking about the old problem not something new in December 2018??
That's my understanding as well. A friend of mine has been in fairly intensive contact with Alaris after having purchased several dozens of rolls of tmx 120 and noting the problem. Alaris eventually informed him that the combination of ink with bad storage during transport (film stored in a trailer that got too hot) caused the problems. In the end, Alaris swapped his tmx rolls for triX, but the whole episode took many months.The effect (AFAIK) happened before you purchased and exposed the film!!!! It was the product of a bad batch of paper + ink and bad storage before purchase.

My confirmed belief now is that image forms after exposure (if you shoot and then develop much later). Unless you break the seal before using. But it forms during unsealed storage.
