Sooo.... that did not go well
I thought I had the set up correct and the correct exposure time, but on my 10x14 screen only half the screen had images on it and of those that did show up- they didn't turn out correctly. The areas right under the bulb didn't turn out- which makes me think I overexposed my screen. I used a 150 watt bulb in a reflector 12 inches from my the screen. I exposed it for 45 minutes.
So I did my second screen, and there are faint yellow lines where the images were, but when I rinsed them and tried to print- absolutely nothing came through- on the entire screen. It was a 16x20 screen that I exposed for 1 hour 32 minutes ( the bulb was 17 inches from the screen)Was that too long? Not long enough? I have no idea what happened with that one
So, I am appealing to you screen printing masters- what did I do wrong?
I think the reason the images that did process were wonky was because the original images were not opaque enough. So I am going to print out multiple transparencies with the same image and over lap them when I burn my screens again.
Sorry for all the questions, but I am a complete newbie at this method of screen printing and I don't want to waste any more photo emulsion
