Curing Finished Print...

no

The shirt will catch fire before the ink is cured. You would be setting the shirt on a wire rack and the metal gets hot causing the shirt to combust or the very least leave scorch marks. You can cure shirts on the press with a flash but the best way is to use a conveyor dryer, this way you have complete control of the temp and speed the shirt travels through.

Duck,
It is possible to use a regular bake oven to set the ink if the top element is all you use. A shirt can take quite a bit of heat before it scorches.
If you have no other means of curing the ink...get a oven themostat and set the temp too 320 degrees. put the shirt in there for no more or less than one minute.
It will slow you down, but it will also do the same thing as a conveyor...which is cure the ink at 320 degrees. Be careful not to put the shirt too close to the element or it will over-cook. A flash-dryer is to unpredictable to use as a final curing unit.
Luck to you.....
