Curt, wow old post and still questions! I'm using this to do 8x10, 11x14 and 8x20 contact prints. It has glass and the glass forms a seal on the rubber seal and I can control the pressure with a bleeder valve. Either Azo or carbon transfer prints. I have switched to a NuArc 26 1KS unit that has a nice built in vacuum frame and pump and I have gone to printing in carbon only.
