I am using the diazo based that came with my kit Prochem WR-6 and its ok but, fine detail isn't going to happen. I was thinking of using another type but I don't know a lot about them. Any suggestions. I'm using a (2) 500 watt exposure setup with glass top and black foam with weight to hold the stencil down and some details come out fine but some at the same location and size may blow out or wash away or refuse to release at all and this can change from one screen to the next with the same graphic I have tried to produce the same graphic 3 times, large graphics/type work fine. prewash and set three to five minutes reviles a nice crisp graphic but they final wash craps out different each time.
