    I have never had a problem with light coming in through a red window. I suspect it's the ink transfer rather than light.

    I think you may be right. Since the markings and numbers are evenly the same 'exposure' on the negative, I'm thinking the ink rubbed off onto the emulsion. Also the numbers aren't reversed if that makes a difference

    That's settled it then. It's ink transference rather than light through the window.

    If it happens to all your films in equal measure the definite test would be to develop an unexposed film, but as Steve Smith says there's sufficient evidence to blame the ink rather than the paper.

    Just because it never happened to you doesn't mean it can't happen to someone else. I've had it happen with Foma and Efke film with both a Zeiss Ikon Nettar and a Kodak Tourist.

    Yup Tom, me too! I knew better, but took a chance with an old folding Zeiss camera a short while back. Efke film in that camera and several frames had some faint numbers on them. So, yes it does happen. Might not be the case with the Lucky brand film, but I can't believe they would continue to use the same paper/ink if it were a bleeding problem. JohnW

    I have only had this probelm with Efke.

    I took the backing paper and reattched the negatives to it, and iscovered that the images of the numbers appered where the numbers actually touched the emulsion, in other words they were offset to where light comming through the back of the camera could cause them to appear.

    Avoiding this sort of trabsfer is the reason that has been given for the Light coloured print on Ilford roll film.

    If the markings have same exposure , I think paper printed its ink on to your film. What is your camera by the way ?
    I wish you the best luck ,changing your film and supplier would change everthing.

    Quite possibly humidity. They were stored in the fridge until we moved and haven't been put back in. I'm thinking moisture caused the ink to transfer onto the emulsion.

    It's easy to tell if it's caused by light through the window or by ink transference. If the number appears in the same place on the negative as the window is relative to the film gate (i.e. the centre of the frame for 6x6) then it's light through the window causing it. If it is offset by about an inch, it's ink transference (or reaction) to the emulsion.
