I used a strip of board as a leader, with the two sheets taped to either side of it.
For alignment hold them against a bright light and match the drill holes up.
If your laminator tends to pull on one side (one driven roller) it helps to put the stack in a folded piece of card stock.
Still dicey at the best of times, even if you get the alignment right there will always be dimensional distortion in a laser printer, and shrinkage of the paper.
Yes you can print on the same area, and pre-dry the paper before use, but If I had to do mostly double sided boards I am not sure if I would select toner transfer. The fiddling about kind of defeats the simplicity of it all.

Hello,
What methods are being used for successful toner transfer to a double sided board using a laminator?
I've tried several different methods without much success. Keeping the two toner transfer sheets aligned to the two PCB sides while going through the laminator has been difficult at best. Single sided PCBs are okay with the laminator.
I'm using Techniks "Press n Peel" blue sheets as the medium for transferring the toner to the PCB.
