When printing on white shirts, I use DTG (Direct-To-Garment) printing. This is a fulfillment technique where ink is sprayed onto garments, much like printing on paper.

When printing on black shirts, I use DTF (Direct-To-Film). This is method where design is directly printed onto a special film using water-based inks. The film is then coated with a special adhesive powder and a heat press is used to transfer the design onto the fabric.
