My work on making flat labels continues.

I tried to fuse toner to a piece of galvanized steel. The first problem I
encountered was the inferior thermal conduction of the steel versus copper.
I ran the metal with toner on top through the laminator 15 times rather than
the suggested 10. I also had to rub down some of the toner because it would
not stick. Then, after 40 minutes in the freezer, I peeled off the wax paper
and found that the toner was barely adhering.

I wonder if the zinc coating prevented the toner from soaking into the pores
of the steel. Seems reasonable. I will try some bare steel and then aluminum
sheet. Certainly do not want to pay for copper if I can help it.
