Edge markings Ilford / Kodak

Why do Ilford 35mm films have a sort of bar code on one edge and the Kodak films not?

Just something I have been wondering for a while!

Not an answer, only an additional question, actually... Sorry about that

Do all Ilford 35 mm films have this bar code? Maybe it's because I've been using meterware for a long time, but I'm not sure FP4+ and HP5+ have this bar code.

I'm sure the Delta films have it, though.

My first guess would be: so that printing machines "know" which frames to print, when ordering specific prints from negatives? FWIW, every colour film I have seen has it.

Dear Matt,

The 'bar code' is for automatic detection of frame numbers in suitably equipped photo finishing equipment : The 4 digit code is there so as we
identify from which parent roll that actual film slitting is from for QC
purposes.

There has been a bar code on Kodak motion picture films for quite some time.

Thanks for that Simon - so does that mean that the Kodak films are 'inferior' when it comes to a suitably equiped photofinishing machine?

Dear Matt,

No it does not, many of the most modern machines do not need them, perhaps ours may be a bit more user freindly on some machines.
