I am curious of others home made exposure unit setups-emulsion-burn time.
Especially how close your bulbs are to the glass and your burn times??
I made a 6 bulb UV Blacklight unit. Bulbs are 2" from the glass. No vac blanket, just weights on foam/wood
I use Ulano QX-1 Emulsion
With NON-halftone burns...I burn at 20 seconds
With Halftone burns.....I burn at 15 seconds.
Here is my ass kicker....I think my bulbs are too close to the glass because sometimes I get like a "hot spot" in the center of the screen were it does not wash out...but only with a halftone burn.
So, what is your set-up?
