Thanks to you both for a timely reply.
at this point water slide is looking more promising than sublimation, but nothing is being ruled out.
the sublimation process seems simple and the tech already exists. and the glass can be treated at a low (400 degree) temperature allowing us to run small wrapped batches through an oven for just a few minutes. they could then be pulled out, replaced with another batch, and allowed to dry at room temperature. no one can tell me how permanent it is, or if the polyester coating will stick well to glass, or off color clear glass. I know there are some differences between glass types, but is anyone sublimating flat glass with any permanency?
the water slides seem like a more difficult method to cure (at 1600 degrees) and have to cool slowly to prevent "glass sag". this would slow the process to a crawl allowing 2 or 3 batches to cure a day. if our screen printing inks can be used however, we know for sure that they will take 500 washes. this may mean modifying an inkjet printer to run a very strange ink. potential for clogging and smearing here seems like a nightmare.
any more thoughts would be greatly appreciated.
