Title: Quick need. rough Exp time-230 on Starlight using 2/1 and Pro Chem Photo Blue?
Post by: Dottonedan on November 12, 2019, 05:33:37 PM

Our press op/screen burner is out today. I'm looking to burn a screen and he doesn't have any burn times written down. (I know).  I'll get with him on that later.


Here his how we have done it.


ProChem Photo Blue emulsion.


2/1 sharp side.


Starlight exposure unit.




Anyone have a round about exp time on the 230 mesh?

Probably won't help.

Our pure photopolymer Chromablue is around 6 seconds

Our UDHV Diazo DC is around 50 seconds

I do 2/1 round side with Chromalime at 5 seconds on a 230.

It helped a lot.  Thanks!!!  I went with 7 seconds. Extra time couldn't hurt. It was solid art.  Came out great.  Thanks ALL!
