I am going to do a regimented developing of a roll of HP5 in D76 and see what happens.
I do see the scratches (parallel marks in a variety of directions), but I was trying to address the "wavy lines" described by OP - which I really don't see in his pics. So I probably shouldn't have commented at all.
As two types of film base are affected, and presumably two styles of film development are used, a common cause seems to lie outside the actual processing. I find it hard to believe the idea that pre-soaking the film can scratch the non-emulsion side. So I'd like to ask how the film is stored before use? In a freezer compartment of a fridge or just in the cool compartment? And how quickly is it normally warmed up to room temperature?
I keep the film in the fridge until it is ready to be used. There is usually a couple of hours between storage removal and use.
Have these negatives been printed yet? Do the lines show up in prints? If they do not, then why worry about it?
You might want to sacrifice a sheet right out of the box to check for problems. You can always use it for fixer checks.
What was your temperature control like ? By that I mean how accurate and consistent between all the stages of processing including washing. It looks like the emulsion has been significantly softened, maybe has reticulated, it would scratch incredibly easily.
I use HP5 it's my film of choice for hand-held LF work and I find the results outstanding, I also process at 26-27°C when in Turkey, that's the water temperature in the Summer and it's easier to be consistent, however I've never had a problem with HP5, Delta 100 & 400, Tmax 100, or Fomapan 100 & 200.
Rodinal contains Potassium Hydroxide and that can soften emulsions, along with poor temperature controls you might get issues. I say might because I never used HP5 & Rodinal although I used Rodinal for over 25 years with other films again no problems personally. I jave seen a problem with someone else processing.
Quit squeegeeing the film. Use a good surfactant such as LFN after washing instead. This can easily be the source of all of your scratches, both straight and wiggly.
Dear Snay 1345,
Firstly, I am sorry you have experienced an issue with an ILFORD film.
I cannot be 100% certain, you cannot be until you see the negs but its highly unlikely to be a problem with manufacture, especially across the two formats.
We have a QC ( quality control ) list where I can see any current QC's in our system, we have none related to HP5+ at all across any format at present.
The most important thing is that you bought an ILFORD film, you are obviously entitled to have it checked out, you need to tell us the batch numbers and return the negs to us ( Marked for technical service HARMAN technology LImited at the UK address ) and importantly tell us if you want the negs back, we will then examine the film and tell you what it is.
You will get one of three answers : Cause Justified = A problem existed in manufacture
Cause Not Certain = We cannot be conclusive as to the cause
Cause Not Justified = No problem in manufacture
If its the first or second we will obviously replace the film free of charge.
Finally some contributors mentioned pre-washing : Firstly HARMAN technology Limited do not recommend pre-washing as we do not believe it is required for even development of modern coated emulsions, BUT If you choose to pre-wash it, it is perfectly safe to do so ( but as with all films not overlong ) and will not harm the film in anyway.

I have these long wavy lines on whole length of the hp5+ 120 film. Development process was like this: pre-wash 2x30 secs, Rodinal 1+50 for 12 minutes, agitation 45 secs + 10 secs every minute, quick wash, stop bath 90 secs, quick wash, 1st fixer 90secs, 2nd fixer 90secs, ilford wash method, 120secs final wash in ilfotol 1+200 solution. Hanged to dry without squeegeeing. I have crud in city water so i use demi water in whole process.
What could have caused it?
