I am such a brain dead idiot. Once I finished my move to the US i restocked my film supply and what did I buy? You guessed it, TMAX 400. How could I not remember this issue? My last 5 rolls of film in China were all ruined by this number problem and what do I do? But into the problem all over again. I can't believe how stupid I am to have bought 20 rolls of TMAX 400.
In failure analysis one should never eliminate possibilities without evidence. It's usually not the fault of variables one knows about. It's usually the fault of the variables one doesn't know about. Or never considered as valid candidate variables in the first place. The problem is a problem precisely because unexpected things happened, so best to look at everything before dismissing anything.
Remember Occam's razor: "the simplest explanation is usually the correct one"
In this case, the simplest explanation is photo active ink which would result in a dark image on the processed film that had been in close contact with that ink.
And that is a known issue with other backing papers.

Then I suppose we can't rule out space aliens.
Simple is the best place to start.

according to the manufacturer they believe it might have been due to extreme heat
( what i was told during a phone call i made to them at the time of the other thread )

Another completely different session of mine with T-MAX 400 film:
sigh, im not passing these rolls through x-rays/IR, putting these rolls through extreme heat or cold, or even wrapping them too tightly...this is kind of crazy to see in two totally different sessions!
But who knows how the film was handled before you got it.

they couldn't be certain unless they were sent the film, and backing paper to
do tests and examine the product ... i don't think they were sent anything but scans of the issue ...
We have seen enough TMAX 400 go bad from locations all over the world to know that clearly this is Kodak's problem. They either have a problem with their product, or they have no clue on how poor their distribution systems is. Or both.
The film I bought in China that was covered with numbers was new stock, not old.
Has any of my Fuji 120 film showed up with numbers? Not a single time (and I shoot waaay more Fuji film than Kodak, so the odds would be against Fuji).
Has any of my Ilford 120 film shown numbers? Nope.
It's Kodak.
Guess which film I won't be buying anymore?
My local store buys some of their Kodak product from B & H because, even with shipping and importation, it is cheaper for them to pay retail to B & H than it is to buy wholesale from the authorized Canadian distributor.
All it would have taken is for one delivery to B&H to be compromised and the effects could have been felt around the world.
Kodak is responsible for that failure.
