I do anywhere from 6 - 12 passes through mine.  I use high-clay 
content glossy magazine paper.  My favorite issues are "GEO WORLD" a 
GIS trade magazine we get in the office that no one reads --we only 
had 1 project a few years ago that we played with GPS plugins.  
Anyway it's a fairly high quality publication; unlike EEtimes, 
ElecDesign and such.  Low recycled paper pulp makes for more 
consistant transfers.  The Laminator I use is a Royal Sovereign NR-
900.  It'd be nice to use the new Dynart laminator, but I can get by 
with my current one--it really doesn't take that much to pass it 
through a few extra times.

Anyway, here's a link to a CPU-board I did using TT(for the one 
asking about a Z-80.)  This one is a 80188(+) with RTC, FPGA, 2 
serial ports.  The crystal daughterboard is from when I was playing 
with different clock frequencies; I changed it out a few times and I 
eventually started pulling up the smt pads --even with the hot air 
pencil.  This board has been well "loved".  The board was perfect 
when first built --no toner dropout!; until I started tinkering with 
it.  The 32pin tsop (middle 32 pin flash socket) used 8 mil traces 
and it came out great until I wiped it down with solder/solderbraid --
to coat the traces.  A couple of traces were pulled up and I repaired 
with stripped wire-wrap wire.  Also there was a miswire also under 
the socket.  It was a test for a netlist for the 4 layer board to 
come later (BTW worked perfectly as soon as the artwork cameback).  
Anyway, I've clocked this up to 50MHz with no functional problems, 
although I'm certain it was a RF noise generator.  I wanted to build 
another one, since I didn't take pictures when I first did this one; 
but couldn't bring myself to drill that many holes again for vanity.  
Anyway, your Z-80 should be no problem with a little care in layout.
