A couple of notes I should add here.
I did some experiments with a cross-hatch pattern based on 4mil traces.
With one pass through the laminator, the traces end up slightly
thinner than the original. With two passes, they end up a bit thicker
than the original.
I've collated the results into a single image, which compares the
original artwork, the transferred toner and the etch result. Note that
this was 1 pass through the laminator.

offers the quickest, cheapest, easiest and most accurate medium for
thermal toner transfer.
For fine work, there are two choices:
1) Use thinner traces with more spacing, do 2 or more laminator passes
2) Use thicker traces with good spacing, do just one laminator pass.
Cheers
