Metal plates are not a bad idea and can make for more even results. But the
iron can also work great by itself, holes and moving it shouldn't be a problem.
Use the tip of the iron, and only tack down one corner of the print good
enough to stick well. Using the tip work a diagonal line through the print,
then work out from the middle diagonal line to the other corners, then go back
over and give good heat and pressure to the whole board. If you're doing the
whole iron at once at first, you're very likely not getting the toner stuck well
first and shifting things slightly while initially moving the iron. You want to
work a good tacking in first without shifting anything, then get the good
transfer heat and pressure to get most of the toner on the board.
And if you're not already doing it, you should run the print back through the
printer several times for the extra fusing before the transfer. Much improved
the results from my transfers.
But it may still all be just thick toner from large particles, and you'll
probably never get everything consistent enough to always get the same results
from thick toner. The range between too much heat and pressure and too little
is just too narrow with a large easy to smash particle. Even with the metal
sheeting it may be hard to keep things consistent.
I only ever really got OK results from previous attempts, never the good to
excellent that I since got from the 600 DPI printer. I really need to go back
though and try the other techniques I now do with the other printer, and see how
much of the quality loss is really just the toner and resolution. I imagine
it's most of it though, good results came fast and easy on the 6L.
