As people have discussed previously, Affliction or Archaic or Warrior style prints are either done on a belt printer, printed before sewing and a few other ways. I have also seen some use a water based ink screenprinting. Having said that, if you get creative, you can do some "out there" designing on shirts of your own using
DTG style printers and/or transfers. All depends on what your creative processes allow you, and money of course
