Luster, I think that's a great idea. I would be interested!
I just got my thermofax fixed and was thinking about offering a thermofax service. A thermofax screen works almost exactly like a silkscreen. Basically you would send carbon based photocopies of your design. Ink jet or laser prints will not work. I could make copies in the right format for people if this is too dificult. I would then make a thermofax screen for you that you could use to silkscreen Tshirts, card etc.... I was thinking a 7 1/2 x 10 image would be $15. It would also be an aditional $5 for the screen stretcher, but that is reusable so you would only need one. I would also figure out a cheaper price for smaller screens. The turnaround time would be super quick also. Do you think anyone would be interested? It would make printing custom stuff super easy!
