More than likely that is reverse painted. In my experience most vacuum formed pan faces are painted from the inside. We have a few wholesalers that do vacuum forming, not a common thing for most folks to do in house. I am sure the technology has changed since I knew what I was talking about so some of it might be digitally printed these days. You could always do a flat face (might get lamp lines as a result) and decorate it however you want. Or you could buy a white pan face and put graphics first surface. I always felt if I had to buy a custom formed face from somewhere else I might at well have them paint it too.
