The light intigrator IMO is one of the best things for exposure. It is the most acurate way to expose the emulsion properly. Bulbs age, temps in the shop change and since the bulbs are gas ignited the temps make some differance. If you expose a screen for the proper light units and you have issues you can narrow it down quickly to either too high of humidity and the screen hadnt dried properly or reasorbed moisture or bad emulsion if the humidity is ok. The only other thing could be is if someone messed with the calibration on the intigrator. Ony maintenace should be bulb changes and maybe a calibration (not sure what intigrator Nuarc ses) For about the same money I would go with the Nuarc. I have a converted halogen blacklight to metal halide exposure unit and I am planning on adding a intigrator to it soonAnyone have any thoughts on the Photosharp vs the NuArc 3140? I know with the Photosharp I'm limited to 25x36 opposed to 31x40 and there's a light integrator in the 3140 but I'm concerned about the maintenance costs and uptime of the 3140. Light integrator is really cool but from reading here it seems not really necessary if you take care to document your exposure times and use an exposure calculator and microscope to get good exposures. Also heard it explained that the more bells and whistles the more it's like a Ferrari, great car but higher and more frequent maintenance. Of course I totally trust M&R for support but I hear Workhorse has good support too.
Just thought I'd ask the hive. Thanks!
