We have been using a heat press and Alpha Jet Pro Stretch transfer paper for a year now. We are looking for a process that does not leave a residue around the printed area. We've seen other vendors do tshirt pressing on site (at AAU basketball tournaments and Junior Olympic events) where they simply put the paper transfer on the tshirt, press for 4-5 seconds, lift off the paper and only the 'ink' is left on the shirt. They appeared to be using the same transfers on light and dark shirts. An example was an American flag design. On a dark shirt, the white stripes and stars were printed, but there was no white outline around the image. That would tell me that it wasn't on opaque transfer paper for darks---it's something else. On another design, there was open space between letters and there was no 'glue' left around it like happens with heat transfers. The operators were not willing to discuss their 'insider secrets' to a potential competitor, I guess. From what I have gleaned from google investigations, my initial guess is that it may be Plastisol or Chromoblast transfers? Can we print our own? We'd like to be able to use the heat press and Epson printer we already have.
