Well Ive dipped my toes into the screen printing waters and after one screen washed out (note do not use the karcher) I managed to expose 3 small screens using a 600 watt halogen and test printed them onto shirts with great success! I had no issues with getting fine lines or anything

(My biggger screen again washed out completely even without using the karcher so Im thinking I will have to expose longer)
now for a dumb question but still best to be safe- as the good screens have been exposed and printed from, do I have to store them in darkness to prevent further exposure creating hassles with reclaiming the screen later or has the exposure process been cpmpleted?
