After you have pulled the 35mm film out and taped it to the leader card, are you winding the film back into the cartridge with the tape on?

How are you removing the tongue from the 35mm film?

If you process 35mm film by taking the film out in the dark and putting it into a 120 cassette do you get the same issue?

Yes, after taping the film leader to the leader card, I wind it back into the cartridge a little.

 

I use a film picker to pull out the film leader.

 

I’m not sure if the same issue would happen—I need to test it. I’ll try it as soon as possible. I haven’t experienced this problem when developing roll film. In fact, this issue wasn’t there from the beginning. It’s quite clear that it’s related to the tape, but I can’t figure out exactly how.

Maybe the splicing tape you are using now is different? Maybe thicker and semi transparent?

It's best to not wind the film back in with the splicing tape on it, as doing so will open up the felt of the 35mm cartridge and allow light into the cartridge and fog the first frame.

It often happens that the operator cuts the tape instead of removing the remnants from the film after development, so they simply cut it with scissors between the film and the leader.

In this case, the tape remains on the film, and its outline is visible when the film is printed.

Here is fogging, most likely due to the semi transparent splicing tape being rewound into the 35mm canister before development.
Probably their old splicing tape was black and thinner so wouldn't have caused the issue even if the tape was rewound back into the film canister.

I’ve solved the problem. It was happening exactly for the reason you mentioned. Thank you very much for your help.
