Response to 120 roll film dries with excessive curve

Curling depends on the thickness and hardening of the emulsion. Thick emulsions with less hardened gelatine (e.g. APX 400) curl very strong. Films like Tmax 100 are the opposite extreme. The thickness of the film base and the coating of the "blank" side my also play a role. In gerneral, it's not a quality criterion, unless you want to make prints with a glassless neg holder immediately after processing.
