Fortunately, this discrepancy can be resolved by a simple experiment. Fuse the toner to the Cu-clad as you have in the past (where the traces merged) then try rubbing them off under water and/or with various solvents. (Hint - start with water, then water with soap, water with detergent, isopropanol, ethanol, methanol, acetone, ... Test each solvent on areas that weren't affected by previous solvents, and on virgin toner.)
Let us know the results.
Donald.
