Direct to garment printing (DTG) is a digital printing process. A digital file (Photoshop, Illustrator, etc.) is sent to the garment printer. The printer handles all the image processing, then injects industrial grade garment inks right into the threads of the shirt. This process avoids the extensive set up process of screen printing.
DTG printing is priced by the number of prints and the quantity of the garments. Because there are no screens involved, there is no per color pricing. You can print a full color photo just as cheaply as you can a one color logo!
If you want only a couple of shirts, or a handful of highly customized shirts (say, individual names and logos on each shirt), DTG printing is for you. At lower quantities (typically 1 - 50 or so), multiple colors tend to be cheaper with digital than screen printing.
We are happy to advise you on which process will save you the most money during your quote.
Traditional screen print jobs use plastic based inks that adhere to and sit atop the fabric. Garment printers use water based inks that actually dye the fabric. This results in a print that is softer to the touch and breathes better.
Because there is no "white ink" to block the dye from the garment from mixing with the garment ink, the color of the garment impacts the color of the print. This means that you're limited to lighter color garments with DTG printing.
