It's been a while since I've printed anything. I was wanting to know a good exposure time when using fluoresent bulbs and Ulano QX-1 emulsion. I plan on putting 2 coats on each side of the screen. Thanks.
Whoever you bought your emulsion from should be able to give you a starting point... I highly recommend getting an exposure calculator... Its a thin strip looks like a photo negative... that you put on your screen during an exposure and it will help you zero in on the correct exposure time for your setup..
I have a couple of customers using flourescent tubes, I'd say start at 12 mins and see how it looks.
Your looking for a clean washout with no scum or greasy feeling on the back of the squeegee side.
If you get a lot of scum and can see the emulsion getting thinner (lighter in colour) then you need to up your exposure by at least 20 % if it is hard to wash out image and fine lines block in then drop your exposure by at least 20%
