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..
