A few years ago I sent out a question about making your own 220-size rolls. Mirko at Fotoimpex answered and said that supplying bulk rolls would not be a major problem, but 220 film needs a special back side coating in order to prevent scratches from the pressure plate as the film is not protected by the paper backing.

Hi Karl,
Do you mean that the backing paper of these 220 rolls is shorter than the film itself? Otherwise I don't understand how it could be scratched. But at the end of the roll (winded up to the take up spool) the film is still covered with backing paper? I assumed the backing paper of 220 might be thinner, but twice as long as the backing paper of a 120 roll film.
Isn't a 220 roll film basically the same concept as a 120 roll film, except for its length?
And couldn't I just "tape" two 120 roll film together into one 220 roll film myself - if I had the right backing paper? In the old days we used special tape to make a big wheel with several short 8 mm films (home movies), to be used in a projector. I could use the (same kind of) tape.
Would be a nice experiment.
I have several 220 roll films left (out of date: 2005):
- 20 x Fuji NPC 160 (= negative color film)
- 30 x Fuji Provia 100F (= RDPIII slide film)
- maybe an other single loose roll hiding somewhere in the fridge.
I don't know to keep, to shoot or to sell these films.
If and when I shoot these films, I will have it developed at a local professional lab, so I can ask them to save the backing paper for me.
I recently bought me a Hasselblad SWC camera with one 120 film back. I just got me a second film back for 220 film. Maybe not a smart move, but it wasn't too expensive (normal backs are) and I'm gonna try to use it with 120 roll film as well.
