I think the hard part is knowing when it’s finished. I mean, I went 5 minutes+ pressing pretty hard on the iron.. there’ no way to see before you start peeling if it succeeded.
I may be doing the paper removal wrong but I’m assuming if the toner hadn’t stuck it wouldn’t matter..

Brad,
80% would suggest that 20% of the board didn’t get hot enough or it didn’t get clean enough.
You really don’t need a brush to clean the paper off if you properly soak it after transfer.
You should be able to wipe the mushy paper off with your fingers.
Using a laminator – a decent business model (I use a GBC) or a cheap one that you’ve hacked to turn up the temperature might help you get more consistent results. It seems that the “cheapies” can be spotted as they don’t have a temperature knob. All those that I’ve seen in my place of work do.
You asked about paper, and I’m guessing here because ordinary plain photocopier paper doesn’t work for me. My guess is that the toner fuses better with ordinary paper but with glossy perhaps not so much. Meaning there is possibly more toner to adhere to the board.
72/3

I did about 5 minutes of solid ironing on each. I did not however try freezing the paper (my method was to just scrub it with a plastic scrub brush under water – seems to work fine. And again, it’s always the same.. I get about 80% including really, really fine details but there’s always just a bit missing in one area or another.
Does that toner transfer paper make any difference? I mean, I’ve seen this method work with magazine pages pretty quickly in youtube videos, however the PCBs people do tend to be quite small. Mine are bigger than the iron surface.
