Can you be more specific on the paper you used?
Thanks,

Rick
I have had equal success using ink jet photo paper from our local pound shop. It is a heavy weight paper, 10 sheets for one UK pound, and the toner separation was complete. It seems that the freezing after thermal transfer is the key.
The 0.005" boundary lines even transferred.

Rick, can you share the source, part number and mfgr, or any other details
about the "special waxed paper"?

today. Wonderful material! I drafted a 1" long scale with 10 major and 30
minor divisions on it using DesignCAD V14. It was then printed, mirror
image, onto the wax paper. I printed 4 coupons at a time.
Two of these
coupons were taped to 2 small pieces of copper plate.

paper fell away from the toner. Then I dropped the two samples in rather
used up ferric chloride that I put out in the Arizona sun.
Every 15 minutes
I would bump the container. After an hour I pulled out the samples. The
toner was solid and I had etched down about 0.001"
according to my caliper.
The fine lines of the scale and numbers all looked perfect.
