Hello

I'm new to screen printing and I'm having a lot of trouble washing out my screens. The image will not wash out without a lot of force. By the time I get the image to wash out the surrounding exposed emulsion becomes damaged.

I'm using a 1500 psi pressure washer, ryonet pink photopolymer fresh stuff, 500-watt halogen 15 inchs away no uv lens, epson 1430 all black with accu rip.

My exposure unit / stand has a black surface with 1/4 glass covering the screen. Screen room has led lights with 12 hours of screen dry time.

I've burned images for 3 minutes up to 15 with same results. If I could just get the image washed out I would be rolling. Any help would be appreciated :/

I would suggest to NOT use a pressure washer for washing out the stencil. Use a garden hose with a spray nozzle and cold water only. Then check your film positive and be sure it is dense enough so you can do the shortest exposure possible while curing the emulsion.

Also make sure you mesh is prepared properly to receive the emulsion.





I hope that helps out some.
