So I printed the image on a transparency sheet and then taped the transparency on the emulsion coated screen and then placed it under a bright light. Unfortunately either the light wasn't bright enough or I didn't leave it long enough. The result was that too much of the emulsion rinsed off the screen so I can not print a clean image and have to start again. I did do a couple of test prints with my kids though and that was fun for them.
Oh well, try it again this weekend
