Sublimation isnt done on black so I would assume its screen printed due to the size and color vibrancy. I dont know enough about DTG to say yeah or neah.
I agree. Looks like regular screen printing with a lot of colors. Possible heat transfer yet too hard to tell without a close up of the actual print/design.
A DTG might work yet would require many passes to get that opacity from what I have read.
Can anyone tell me how this was done? 
look how it sits on the model
