Yeah, more of a crust on the screen with minerals. I'm surprised you haven't seen it, we have. Are you CCWD or EBMUD?

I'm now pretty sure it's the exposure unit it'self. It's the flo bulbs in a NuArc First Light. We are coating 2:1 (round) using SAATI emulsion.I'm told we are getting a solid 7 in the stouffer's step test. If that is the case, then I still think we are a little under...and just enough to leave this residual behind.Alan Howe came by the other day and will be sending me some samples of other emulsion they sell that might be a good fit for us. What we have right now, is not (as good) for halftone work. We haven't tested all mesh on the exp test yet...and I wasn't around to be there when they did test, so I don't know for sure how accurate the initial test were.
