Exposure issues
Posted: Thu Apr 14, 2011 9:59 pm
Hey dudes, and dudettes. I'm sure this is a common issue and I have already tried using the search feature but apparently everything I try to search is "too common." So sorry in advance.
I'm doing DIY screen printing and have run into an issue. The image I'm trying to burn right now is a word that has a thin outline around the bubbled letters. I usually expose my images for around 15-20 mins and I get pretty decent results. Well I have exposed said image up to 30 mins now and have beautiful results with the bold letters after the wash but the outlines are not coming through. I'm using 4, 12" flourecent bulbs in my exposure unit, one coat of Diazo Speedball emulsion (i've tried front and back and it was worse.) I am ink jet printing my bold black image onto transparency film and am exposing for 30 mins. It seems like the longer the exposure time the better but I am worried about over exposing. Any ideas??
Oh and one more thing..
When I go into my room to pull my screen from the drying cabinet to put it on the exposure unit, im basically doing it in complete pitch darkness. Is there any form of light that's safe to use so I can see what I'm doing and not expose my screen?
