Try Yost and Heidke or Heidke and Yost. It is there. I remember their work. I'll see if I can find the number.

Our rolls of bombarded support had quite a charge. When I lifted small rolls, I could feel my hair stand up. We also grounded them and as I mentioned, the discharge was quite visible.

And yes, the mottle problem is severe on RC paper if the discharge is too fresh or if you don't add certain chemicals to the coating or subbing.
