I have some Bergger COT 320 I've started to play with. Please confirm that the "good" side to coat is the extremely smooth almost toothless side. The other side has much more tooth. <p> I am rod coating with Pd. My humidity is around 60%. I got a smooth coat on the paper, but seem to have put too much emulsion down (black runoff on development). I'm not using Tween or anything? <p> Any thoughts? or insights?
