Homebrew PCBs

I've tried the label backing too, with mixed results. I agree with 
Stefan, the surface is just too slick and the toner is easily scaped 
off during handling.

But if you think about it, that level of slickness is the 
requirement for label release. We do not need such slickness for 
laser transfer. So the question is, how to increase the tackiness of 
the label backing.

Having a couple of teenage daughters, there is plenty of hair spray 
in my house. I just put a light mist coat on some label backing. 
There is definately a change in surface texture, a little rough and 
grabby.

It'll b intresting to see if it will run through my old Laserjet 
IIIP+.

Will keep you posted.
