How to flaten a curly film

Hello,

Is there a product to flaten a curly film ?
I tried the Rollei Retro 100 Tonal, but damned was it hard to scan this film !
Perhaps there is a wash addin for that.
It is a synthetic film base.

A full sized Bible was always my choice.
Close the film strips is the Bible (in sleeves or glassines) for a few days and see if that doesn't flatten them out.

Kodak used to make a flattening product (back-in-the-day), but it was not very affective. I am surprised that the non-acetate base is giving you problems, but sometimes how the film is made will result in curl regardless of the base material (i.e. no backing). I quite using Rollei Retro 100 (non-tonal) in 35mm due to excessive curl, but have shot RR 80s in both 35mm and 120 with no problems whatsoever. The RR 100 Tonal is supposed to be an Efke product, so it may be that they had a bad batch and/or are still working out the kinks of making the film?

Pressing the film in sleeve is a good idea, though it may take awhile. It may be too that with warmer weather and higher humidity, the problem may be less as we move into Spring.

I've been putting troublesome negatives in sleeves in a heavy textbook and leaving several kilos of plate weights on top for a few weeks.

Sometimes rolling the film backwards (inside out) and letting it sit in a warm place for a few days will work.

Even God can't help Rollei Retro 100.

Does anyone know if APX 100 suffered from the same problem or is the RR 100 (not Tonal) curl a characteristic of the film confectioned with Rollei branding for Maco/Mahn?


Steve

(Some clarification...RR 100 is made from leftover sheet stock of Agfa APX 100 confectioned (finished out and packaged) as Rollei and is considered to BE APX 100 for most purposes. RR 100 Tonal is a completely different film.)

If the question involves wanting flatter film for scanning, anti-Newton ring glass "pushes" the film flat without the little rainbow rings that occur with regular glass. Found a couple different film carriers for my old scanner with anti-Newton ring glass which solves my problem. Storage in glassine sleeves stuffed into archival pages in spiral notebooks assists with flatness issue as well as analog cataloging.

This new (to me) non-hardening eco-fixer I'm using seems to help a lot with this. Whatever it is about the water down here: it rinses well, but, it'd been making the film really really curly and stiff. This stuff seems to counteract that tendency pretty well.

For my scanner, (Which is glitchy, or I'd have done this some time ago) I really just want to use proper negative carriers from an enlarger and add a little of a spacer to make it sit at the standard height.

Retro 100 also scratches easily, so I wouldn't use a non-hardening fixer.

That is so true, although the OP is not shooting Retro 100. He is shooting Retro 100 Tonal, a different film.

I've done that with C41 from the Minilab. They like to put the neg roll back in the film can, where it get curly.

For B&W I don't have much trouble if I have a good strong weight on the bottom. The little weight in the film holder is not enough. But then, I haven't shot Rollei Retro.

I shot a lot of APX 100. Bought it in 50 ft. rolls.
Yes, I always had a curl problem with it. But it was still my favorite B&W film.

I don't recall any curling problem with the APX100 film I used in the late '90's.
I believe the original Agfa 35mm APX100 film was made on a thicker base.

I have to agree, i'm just finished trying to scan a roll of the original i just developed. 2 weeks in it's sleeve with about 25 lbs of texts on top. Still a little curled.
