T-shirt printing is the process of creating designs, images, or text on a T-shirt using various printing methods. There are several different methods of printing on T-shirts, including screen printing, digital printing, heat transfer printing, and vinyl printing.Screen printing is the most common and traditional method, where a mesh screen is used to transfer ink onto the fabric. Digital printing involves using a special printer to print the design directly onto the T-shirt. Heat transfer printing involves printing the design onto a special heat transfer paper, which is then applied to the T-shirt using heat and pressure.
