The open areas on the edge of the screen are blocked out and then taped over. The screen is attached to the press, which is essentially an arm or hinge that moves up and down. Ink is added to the screen. Every new print requires two passes with the squeegee, the first to fill the reservoir of the design and the second to press the ink through the screen onto the shirt. The shirt is then dried under a high-heat heater to allow the ink to cure and voila, t-shirts.
