An amateur screenprinter attempting to start out with a few designs. I've built my shirt jig, have my screens, emulsions and inks. However, while I want to rely on the sun for my exposure, I find that it's cloudy often most of the days, and I usually get home too late from work/school (6/7++) to really be able to have a chance to catch the sun's free rays, thus sadly, the sun isn't an option as an exposure unit.
So here's my question, what's the cheapest way to burn exposures reliably? I have an exposure calculator, and really, I just need something that will burn my screens consistently each time.
