How many t-shirt you can print with manual silk screen printing in an hour?
If the shirts were already on the stretcher forms ahead of time, one could reasonably screen one every ten or fifteen seconds or so. So, say fifteen seconds per shirt makes it four per minute times sixty minutes, equals 240 shirts. But, of course, no one has 240 shirt forms handy and, working by oneself, one would have to pause, re flood the screen with ink, wipe up any splashes or loose drips, breathe, take a sip of water, etc. In practical terms, a more reasonable would be about 100 shirts in an hour, using just a manual screen, on a hinge and regestration stops in place to help line up the shirt to the stencil.
