Cheap film is another matter (if it's in date) ....I don't think there are any bad films about, as all own-label color now comes from either Fuji or Kodak (maybe Ferrania?), and none of these companies supply rubbish. Truprint used to be from Agfa (also good), and (I believe) is now Fuji. Even if the film is an "earlier version", it should be fine with good quality processing.
Thanks everyone,

I had a good look at the negative and while the orange strips are just about noticeable on the negatives there is no sign of physical damage and the neg surface SEEMS flawless. It looks like the blue strips (as they appear on the scans) are a part of the image as it appears on the negative. Could this still be a case of a dirty scanner? Or maybe a bad film? As I say, previous rolls with the same camera have been fine, but I've only shot it in bright daylight until now...

Thanks for the info re cheap film, good to know. The reel I shot was completely unmarked, date wise so could well have been way out of date, it was part of a super cheap ebay bulk buy of old film and I have no idea where it came from, if it had been stored well etc. That said, I've got great results from other films of the same type from the same pack, but I did send them to a much more discerning lab...
