Am guessing it's a form of silk screen printing, did that for YTS when I first started work, many years ago.
I asked the supplier for more details - this is what they said:
"Heat Transfer is as durable as screen-printing, but offers more detail. Heat Transfer uses heat to create a bond between the resin and the T-Shirt, locking the ink between the two layers."
