i prepare the copper with 600grit paper for the initial transfer for
etching,
i thought i can omit this step for the legend.
The toner seems to hold very well t th gh epoxy surface where the copper
was.

I'd like to not use a iron and a rather tedious step in production,
i will try a few things with the fuser and let you know...
