I thought this might be helpful to some people. This morning I decided to try a new technique on some cut scraps of Proof Grade acrylic and Proof Grade med. maple plywood. I am very happy with the results and believe this will lead to many more possibilities.
I have an Okidata 610 color laser printer that I purchased from the Magic Touch about 3 years ago and an Insta Graphic swing away heat press that I purchased from Conde Systerms two years ago.
Using the TechniPrint HS (hard surfaces) transfer paper, I printed out three designs and transferred them via the heat press. The above pictures are the final results.
For the acrylic, I pressed for 30 seconds at 321° F, and then I rotated the acrylic 180 degrees and pressed for another 10 seconds. I used medium pressure. I let it cool for about a minute and removed the transfer paper.
For the wooden pumpkin, I pressed for 120 seconds at 325°F, waited about one minute and then removed the paper. I used medium pressure.
I probably need to refine the time and temp a little bit more, but nonetheless, I am very happy with the results.
This is similar to the technique used by some to prototype PCBs. You print on a glossy magazine or the release back from an adhesive label using a laser printer, then you can transfer that to the surface of your copper clad PCB material. I usually use a clothes iron. The toner acts as a resist to the acid used to etch the copper.
