8 bulb DIY exposure unit, last used 1 week ago (burned fine)
Normally use ChromaBlue Emulsion
I get burn times of about 2 minutes for a N128 mesh
Today I just opened a new batch of ChromaTech PL 2 for a halftone job. It's not expired. I've got N272 mesh and round coated 1:1. The "user guide" for the emulsion suggests 30 second burn times on N128 for the Chromablue and 20 second burn times on a N272, (assuming they're using single point, metal-halide for those times)
Both emulsions have identical burn times in their user guide. So I figured for the N272 and ChromaTech PL 2, based off my ChromaBlue times, I could start by trying a 1 minute burn time. Well it completely washed out, easily... Is there a sweet spot with this emulsion? I've never had anything wash out completely, it either was over exposed or I've had some sort of image burned. Could it be bad emulsion? Should I just go back to my Chromablue and would that be sufficient to hold the halftones? 45lpi Or I extend the burn time and see what that does. Just wondering if there's an easy answer here?
EDIT/UPDATE 2:00 minutes exposure didn't help, washed out easily.
Single point or multi bulbs? May have to dial in my times a little closer for these half tones. I'm always around a 7 or 8 on my exposure strip. Just recoated with the chromablue and now waiting for that to dry. We'll see how this comes out.
