| Just getting started burning screens with QTX emulsion on a NuArc 3140 exposure unit. I applied one coat to each side of the screen. The unit has a 1200 watt metal halide lamp. according to the tech sheet I should expose for 22 seconds however the 3140 measures exposure with light units, not seconds? Any idea how many light units I should try to start with? | ||
