Direct to garment printing (DTG) is the process of printing on textiles using specialized ink jet technology. DTG printers have a platen designed to hold the garment in a fixed position and the printer inks are sprayed onto the textile by print heads. DTG requires that the garment be pre-treated with a PTM or Pre-treatment machine allowing for a stronger bond between garment fibers and the pigmented inks, laying down loose fibers to provide for a smoother substrate and chemically reacting with the inks to promote drying and curing
Since this is a digital process the print is sharper and has a higher resolution, or DPI, than traditional 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 for minimal cost.
