I need to see it....
I immediately thought......camera problem... I still do.
Or a loading issue, but its important to get the facts and see it, upsetting experienced photographers who know their kit sounds patronising and frankly its not our style, we find out the reason.
As to 'film widths' on all film sizes ( I mean every film size imaginable ! ) an ISO standard exists, KODAK, ILFORD and FUJI will cut to this, and the tolerences are tiny, much less than a mm, so I am surprised at a noticible difference between 120 film sizes.
Simon ILFORD Photo / HARMAN technology Limited :
Can you try to photography it in front of lightbox or a computer screen with a white image?
I measured the width of a rolled-up 120-size Delta 100 backing paper with dial calipers as 2.468.
I did the same with the negative stip. It measured 2.412 for a difference of 0.056 = 1.42mm.
IF the film was somehow shifted completely to one side relative to the backing paper, then Id expect that, at most, one margin would be half that amount, 0.71mm narrower and the other margin 0.71mm wider than the usual situation with the film centered over the backing paper.
For smaller de-centering of the film relative to the backing paper, obviously the effect would be less.
Might this be the effect that was observed in post #1?
If so, Id suspect that the automated machinery that unites the film and backing paper might have been out of adjustment temporarily until noticed and corrected. Even if this did happen, the negative should be otherwise perfect and satisfactory for normal use.
I am wondering whether Ilford (and Kodak and others) have a defined tolerance for the placement of the lettering, and if the movement you see of that lettering is within that tolerance.
It may be that your film gates are quite generous, in that they give you more image area than most. For most people, that wouldn't matter, because very few people make contact prints from 120 negatives in a situation where intrusion of the lettering into the extra image area would create a problem.
if the edge of the film is where I think it is then it looks as if the Ilford writing in each case is in the same position and couldn't be closer to the edge without falling off but the film area overlaps the writing until you get to the last frame where the film area contracts enough to give clearance to the Ilford writing.

Judging by your attachments, it also looks as though the edge of the negative area is of consistent distance to the film edge.
The pictures you showed do look like there's a lot of "wandering" in the image area, all right. Just to make sure, have you confirmed that if you got the *image* placement of the Kodak films, the larger imprint area on HP5+ would not overlap?---that is, in the worst case for Kodak image position, combined with the worst case for HP5+ imprint position, is there overlap or not?
The film gate isn't moving, so it follows that the film must be (sorry to belabor the obvious, but this is a weird enough result that I think it's worth questioning what we think we know). Have you tried placing the affected films against the gate, in room light, and seeing where they have to sit in order to account for the image position?
I'm just brainstorming here. It seems obvious that this shouldn't happen.

Shawn, I took your pictures and put them side by side on a single image.
You can clearly see that the distance of the text to the edge of the film is inconsistent.
I have some HP5+ I shot back in 2004 using a Rolleiflex. When I get home I'll dig it out to see if there is any correlation to what you are showing, Shawn.
Thomas, you are absolutely correct on that account. Both the distance of the text to the edge of the film AND the placement of the image area in relation to the edge of the film vary. And the problem is at it's worst when both of those things happen.
That said, the "snaps" I took were made handheld at different distances so lining them up isn't going to give accurate distances. BUT you are still correct, you can plainly see just looking at them that sometimes the logo is right on the film edge and sometimes the logo is moved up a good bit from the film edge.
I would expect some slight variation from camera to camera, back to back and possibly roll to roll with respect to the image placement. In most cases, cameras use movable parts to position the film spools for 120 film, and those parts will wear.
You probably wouldn't see such movement with films that have perforations.
Strictly going off of memory, but I gotta agree. I can attest to how finicky film backs can be. Spacing issues, overlapping, slightly off center on the strip, etc etc. Also my images are slightly smaller than when taken with my Rollei and this is across the board for film used.
Regardless though, it does seem odd, that this was something the OP never noticed/witnessed with the same cameras/materials and then over the past few months started having this occur. Either something in the tolerances changed (although not sure what) or the camera is now resulting in slightly larger images or more off center than before? I mean the photos do help, but it seems there could be a myriad of options and reasons.
Hi Shawn, probably of no use at all so apologies in advance, just adding something to the mix. I used to have problems loading a new 120 roll of Ilford film onto a blank Kodak spool. Ilford film always always seemed to be tight on a Kodak spool and on my Mamiya C330s I would notice the paper backing tightening up on one side. I would have to help centre correctly by rolling it over slightly as I wound it on. When I used two Ilford spools everything OK. Not sure that accounts for the movement in the writing you show but just thought I'd mention it. Good luck with sorting it out.
