"He who marches out of step hears another drum." ~ Ken Kesey
it takes 20 prints for the ink to build up properly on the bottoms of the screens. then evaluate and make changes. in theory, you should do another 20 prints to see what it looks like. We tend to rush it and test after 10 or so, but that comes to bite us in the behind pretty often. You'd think we'd learn by now!we probably average about 100-150 shirts before we are happy with the way it looks. On the low end it's about 50 and in the worst case scenario it could go up to several hundred!!!pierre
