The pre-treatment also allows the water-based inks to bond more fully to the garment. The pre-treatment is heat-pressed into the custom t-shirt causing the fibers of the shirt to lay down. In addition, pre-treatment is typically applied to the garment before printing. Since D2 inks are water-based, they work best for printing on natural fibers such as cotton, bamboo, hemp, and linen. Printing process ĭTG printers use aqueous textile inks (water-based chemistry) that require a unique curing process. 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. Since this is a digital process the print is sharper and has a higher resolution, or DPI, than traditional printing methods such as screen printing. Chemically reacts with the inks to promote drying and curing.Lays down loose fibers to provide for a smoother substrate.Stronger bond between garment fibers and the pigmented inks.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.ĭTG typically requires that the garment be pre-treated with a PTM or Pre-treatment machine allowing for the following: Direct-to-garment printing (DTG) is a process of printing on textiles using specialized aqueous ink jet technology.
