DTG printing is where a printer directly applies the ink onto the t-shirt with inkjet technology. It's sort of like printing on paper, except on a t-shirt. A special printer prints the ink directly onto the garment in the desired design. DTG uses specialty water-based inks, which are absorbed by the fibers of the garment.
