HELP! TZ Ulano Exposure!!
So my scenario is this: I've tried exposing screens almost 10 times with TZ Ulano.
When I add the emulsion to the screen I put a thin coat on it and when I expose with my film, I leave it under my Halogen Light with 500 Watts for about 12 mins. When I remove from the light to rinse the exposed area is a light green and the rest is turning grey, when I rinse off nothing and I mean NOTHING will come off.. What I'm I doing wrong???!! I'm super stressed with this and I don't want to give up screen printing because it's awesome. My humidity level is from 60% to 70% could that be it?! My mixed emulsion is fairly new... can someone please help! Thanks!
