Emulsion

<< < (3/3)

Chromablue for mesh counts 137 and up, and Saati PHW red for lower mesh counts and thicker eom's.  I've used several dozen emulsions over the years and I always end up with pure photopolymers.  We don't really have many issues holding 55-65 lpi using the pp emulsion so the need for a dual cure never has really come up.  I guess there are several dozen factors that allow us to get away with that, our light source being like the freaking sun in a metal box and our film must be nice and dense.  Oh and the fact that I'm like a screen ninja :)

Thats one of my biggest problem is light source HOMER!! blacklights do a good job , but not really great for the higher counts like 55 up to 65 which I don't try.  Guess I will have to keep it a little longer just replace blanket, the other one went to heaven it was very holely lol tape everywhere.

Hey Darryl. Look online, sites like eBay and Craigslist for used exposure units. I was able to find Nuarc 40-1K Mercury unit for $350 in mint condition. The only issue it had was the shocks for lifting the glass. With 6 months experience, I expose pretty good halftone screens. Using Chromablue emulsion.
The unit has Mercury bulb and not Metal halide, but it works A LOT BETTER than tubes and it is well worth $350. I replaced the bulb and I kept the old one as a back up. I was able to find the new bulb for $45 on eBay.
