Hi Stefan, I am pretty new to this group , the legend looks fine but what
do you do to the copper it looks like it has been attacked with sandpaper,
is this what is needed to get the toner to stick?. I always prepare my board
with steel wool and then scotchbrite and I never get marks like that. I am
afraid if that is what is needed I will stick to PRP. 15 thou. Teflon board
is to expensive here to do that to(AU 1.50 a sq.inch)
Regards Don.....VK3YV
