  A ton or two may be closer than you'd think off hand, remember the 
rollers flatten out a bit and create a contact patch.  Not sure extreme 
pressure is really important, with correct heat the toner should flow 
without that much pressure.  Reinforcing a plate is easy enough, and 
actually had thought of using a levered hand roller like in the manual 
tile cutter I used last week.  But probably too much work to keep the 
board and print aligned that way..  Just worth investigating a bit, 
since the griddle is useful on it's own for SMT reflow anyway.  If it 
can be made to work it'd be great, if not there is no real loss either..
