Direct-to-garment printing (DTG) is a process of printing on textiles using specialized aqueous ink jet technology. DTG printers typically have a platen designed to hold the garment in a fixed position, and the printer inks are jetted or sprayed onto the textile by the print head.

DTG typically requires that the garment be pre-treated with a PTM or Pre-treatment machine allowing for the following:

- Stronger bond between garment fibers and the pigmented inks.

- Lays down loose fibers to provide for a smoother substrate.

- Chemically reacts with the inks to promote drying and curing.

Since this is a digital process the print is sharper and has a higher resolution than traditional printing methods such as screen printing. However, unlike screen printing, there is no long setup or clean-up process, and DTG has the ability to print just one single shirt.
