Here you can discuss issues related to exposing screens for screen printing. This includes determining the exposure, light sources and washing out the stencil in the washout booth. Emulsion issues may also be addressed here.
I'm farily new to screen printing and have been printing screens for a few weeks and ran into my first issue. For some reason the past 2 screens that i have tried to burn and washout have had issues with the design washing out. When i start to washout the screen all looks well but then the crisp edges start to washout and the area where the tape held the transparency begins to washout as well. I have uploaded a pic of the issue. Im using RYONET RXP Dual Cure Emulsion, 500 watt halogen light about 12-15 inches away for 13 mins.
