I had a bad thick acrylic award that I sanded and buffed up. used alchohol to clean the polish residue.
I pressed at a moderate pressure with image on top of award - green pad on top (green pad is to evenly distribute the heat, I think).
50 seconds-let cool-rotate 90deg- repress. peel cool there may be a skin to peel off.
Award Glow works well to remove some of the unwanted dots.
From harvey's settings for glass, I dabbled and it worked great on a small scrap, but when doing a larger beveled and drilled piece, it cracked. be sure to preheat the glass slowly to temp.
couldn't make stick properly to FRB had to do it so lightly sanded to gov somelthing to adhere to.
Hope it helps

John,
The purpose of the silicon pad, aside from promoting even heating of the substrate, is to ensure the transfer is in direct contact with the substrate.
Even though acrylic looks completely flat, there can be slight variances in the acrylic, or the platen of the heat press, for which the silicon pad can compensate.
That may be why you had mixed results with adhesion of the transfer.
I have very limited experience with OEM toner/Transfer paper on acrylic, through a few transfers Harvey sent to me.
Maybe beginners luck, but the piece I did, turned out very nice. I followed the instructions Harvey provided.

I do acrylic all of the time. You will definately need the 1/8" green silicone pad. If you call we can discuss times and temps for your press. I have gotten some good results with glass, never tried crystal.

For acrylic:
I would suggest that you use a foam pad between the heating element and the transfer paper, press at about 40 pounds and 280 degrees for about 40 seconds. Be sure to peel while it is warm.
You should be able to clean any residue with alcohol.
ps: My printer is a Panasonic 8415 which uses an oil fuser.
I believe the application for glass involves a decal printed by the laser and water transferred to the piece.

I use a laser infra-red heat thermometer to check the press settings. The settings on my tutorial are made with a piece of masking tape over the platen in order to get a stable reading. [Since then I learned that if there is a blackened piece of paper sticking to the platen it reads about 18*F higher, do not ask.]
The silicon sheet is necessary to get good thermal transfer at ALL points. Your results are exactly what you will get with any surface aberration when not using a pad. If you still get it with the pad it is either too low a temperature or pressure. If it is huge areas of toner not sticking it is usually not quite enough heat.
If you start to get an impression of the pad on the acrylic, it is either too much temperature or pressure. Usually it is the excess pressure.
The best way to remove the paper is to lay the piece face down on metal. If it is 1/4" or under in thickness it will have curled. Press down the longer edges for about 10 seconds, curl gone and a lot of heat gone. Then let it stay that way for a few minutes and the transfer paper will start separating by itself from the contraction of the acrylic. After it cools, peel off the paper.
