Direct-to-garment, or DTG, is a printing procedure through which you can spray the ink onto the garment. The fibers of the material ment soak up the ink sprayed onto it. The process is similar to printing on paper. However, it's done on clothing.
The primary benefit of DTG is that it's convenient to print one-off is because there is practically no setup time involved in the method. For instance, you have an online store that connects with a third-party Direct To Garment Printing provider.
After your customer places an order for a t-shirt on your online store, the DTG service provider automatically receives the order. The company then starts printing the design onto the t-shirt. After it's done, the shirt is delivered to the customer, but it's under your label.
