DJ,
Have you tried different brand transparencies?
Before going back to photo etching >10 years ago
I used to do toner transfer from transparencies.
I started doing it in the early 90's after
reading about PARC doing TT in an EA magazine.
Anyway, I found that the transparency had a huge
effect on the transfer.
I got fantastic results with Faber-Castell
OH-LUX. However these stopped being available
in oz, so I switched to the next best ones I
tried. This was 3M Brand CG3300.
With the OH-LUX transfers, I would run cold water
over the top as it was still hot. The totally
clear film would just crack off. I never needed
to apply so much pressure to squish the traces.
The 3M was not as good and the extra heat/time
they needed would sometimes squish traces.
All the other brands I tried that where
available here either didn't take the toner
well from the printer, or never let go well to
the copper.
