Repairing Wrinkled Rolls
By Robbie Rhodes
Paper buckles, not when moistened, but when the moistened area has dried again. Why? It's as though moistening the paper releases internal forces, allowing the surface area to grow. Then it bulges slightly, and causes ciphers at the tracker bar.
I've used a steam-iron cautiously to "tame the music", and it seemed to help, perhaps because the water vapor permeates the region equally, bad and good areas alike. I've not ironed the dampened paper with a dry iron, but this seems logical to try, too. A surfactant, such as Kodak "Photo Flo", might aid even-penetration of the moisture.
John Phillips proposes applying tension to the hanging web of paper, to force it to become flat again. That seems a good idea; more than 50 pounds tension should be possible without rupture if the edges are good. Try introducing the moisture with the steam iron, too. Don't worry about overall-stretch in the roll.
