The last job I did was a 10x14 screen I had from a little speedball kit - no problems there.
So of course after I burn the bigger screen and I see that the outline of the glass is washing out along with the design.
I *think* I closed it up up with red coat block-out fluid but I'm not sure if that will be enough to prevent the ink from getting through. Should I also tape it up? If so, do I tape the print side? or the squeegee side (while I have to tape the edged of the inside anyway).
Would the tape lift up when I'm printing? It's very close to the perimeter of the design.
Not sure if I should just get a bigger piece of glass and do it over.
For the 100th time.
Richard I'm guessing the glass is used when you have an exposure unit with the light source on top so you'd lay the screen and place a piece of glass over it to place pressure down while exposing.
Kenstyles, you can get a larger piece of glass at home depot for $5-$10 about 30x25 but make sure it's doesn't block UV rays. As for the edge of the glass burning a line in your screen, tape the print side, if you tape the squeegee side the tape will lift up after some runs and cause headachs.
