I guess this is the right place for this post, since the technique involves a transfer. I thought I'd post them here since there isn't a whole lot of info on lasertran paper on Craftster.
So, without further ado, here are three shotglasses with images from the TV show "Firefly" that I just made for a swap.
I used the regular lasertran paper with a color laser printer and did the bake-on application method. At first I tried to heat-set the decals in the oven, like it says you can do in the instructions, but it was a disaster - all of the ink pilled up and the images were super spotty. So, I tried again and this time I used a heat gun and it made all the difference in the world!
The first glass (on the left) is one I made with one of the first decals (the pilly oven-set ones), and I didn't like the way it looked, but didn't want to waste the shot glass, so I baked one of the better second decals over it. I was worried about baking it twice, but it turned out okay - but maybe a little more bubbly than I would have liked. The second glass is made with two of the good decals stacked right on top of each other (but baked once) and the third glass is just one of the first (pilly) decals just baked once. You can really see the difference in the intensity of the color between the first two shotglasses and that third one. Layering the decals makes a big difference! (Special thanks to Craftster DogGrrl for that tip!)
One more tip from my experience: the square design on the second glass ended up a little warped because of the shape of the glass. I would recommend sticking to a circular design like in the third glass for a more even look or even one like the first glass that is still square but doesn't have real defined edges.
Thanks for looking! I hope these tips are helpful to anyone who might want to try transferring images to glass!
