It is screen printed with discharge ink.
Hey everyone just wondering what type of printing method is used to achieve that vintage look where the ink is like part of the shirt as 1 layer and not a 2nd layer type of feel such as these designs on this site: Vintage Cola T-Shirts from Tees.com | T-Shirt Blog By 101 Tees I have a heat press so wanted to know what kind of heat transfer paper or printing method to go about to achieve it.
Thanks all.
