Will take a photo of the package and post it tomorrow, as it has gone midnight here.

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

 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.

  times. Then I put the samples in the freezer for 15, not 30
  minutes. The
 
  
 
  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.

  shows promise.
