I am printing on Cranes Planitype paper. It doesn't seem to matter which batch - either bright white or natural white. The bulk of the fading takes place in the water bath following development and then what little remains gets hit in the fixer. I am wondering if the sizing on the planotype paper keeps the emulsion from gripping real well and the highlights expose and develop and then fall off? Maybe I should soak the paper and press it and then coat it?
