PCB Transparency Film

The transparency film does not work so well. I have used it and the toner
is not stuck to it at all and sometimes comes off
in the fuser in the copier or straight lines become wavy ones.

A company makes a product that glossy paper covered with something like
elmers glue. The toner sticks well to the coating and after you iron it on
it easily dissolves in water leaving the pattern fused to the copper. This
stuff is expensive. An alternate method uses glossy photo printing paper.
It works the same way but it may take an hour or so for surface to soften
to allow the toner to remain on the coper. But it does work.

Look at this guy's page on using a laser printer ( works same a photo copier).
