It is a bit of an issue, but it does work with elastic pressure.
Here you see one of the first boards i made with legend on copper, i
believe the first or second ever:

It is on 18u copper, which makes for smaller steps and no break, sometimes.
I haven't really worked on it much, since i avoid having important
information in the gaps, i put the text on copper and use a ground
plane/copper pour usually. You can't read so well across the contrasting
surfaces anyway.

I dunno how it can be done with an iron, i think with something like a
silicone baking sheet you mightn't get enough pressure per area. But Steve
said there are such sheets for use in t-shirt presses, i think...

About the laminator, the deal seemes to have been pretty lame from the
reports here. I'm not sure anyway if those laminators have a rubber roller
or two metal ones.
