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 inksLays down loose fibers to provide for a smoother substrateChemically reacts with the inks to promote drying and curing
