I spent maybe three minutes tops preparing my board for this test
using the same Scotchbrite/Ajax technique. That included removing
toner adhered to the board from my previous, unsuccessful attempt.
In short, by tacking the glossy magazine-cover paper artwork to the
board using a cheap ($30) thermal laminator, bringing the board (in
just a few minutes) to the toner fusion temperature of 200C in an oven
and running it through the laminator again, I get an absolutely
perfect transfer with a laminator that otherwise wouldn't be suitable
for toner transfer. All of this took a matter of minutes and there
were no additional variables related to iron technique or iron
temperature (which would be an unknown for most people since they
don't have a thermal sensor gun to measure it with).
And keep in mind that the reason I purchased this particular $30
laminator in the first place was to discover whether it worked as well
as the previous $99 - $149 Royal model PL2000 which was listed as
being very good for toner transfer. When it didn't, I found a
workaround that should be applicable to all individuals who are stuck
with a thermal laminator that doesn't work well in a toner transfer role.
