That sounds like the carrier for the dye sub is transfering. IE, it is
not working by dye sub. It's nearly impossible to use a hand iron to
do dye sublimation.
Inkjet dye sub is particles suspended in a solvent (water based, in
this case). At about 400F, they vaporize. What probably happened in
your case, is that they did not vaporize, but instead the dried base
of particles and carrier stuck to the metal.
I'd have never thought to try that! It is very expensive, though.
Especially since Sawgrass has been lawyering all other makers of the
ink to death.
