Well today i was in the darkroom printing and everything was going smoothly until the prints came out of the UV box. They were really grainy and looked like there were white speckles on the dark areas. I double coated some of the paper but didnt seem to change much. The room was rather warm today and i was wondering if the paper didnt absorb enough sentisizer and the white paper was showing through as grain. should i humidify the paper before coating? any suggestions?
