Screen printing is a popular method used to decorate apparel with designs, especially for large orders and minimal colors. The process starts by creating a stencil, or screen, for each color in the design. The screen is made of a fine mesh fabric stretched tightly over a frame, and the areas that shouldn't have ink are blocked off. The design is then placed on the screen, and ink is pushed through the open spaces of the mesh using a tool called a squeegee. Each color is printed one at a time, with a separate screen for each color layer. After the design is printed, the apparel is dried using heat, which makes the ink stick to the fabric. The result is a durable, vibrant design that looks great on t-shirts, hoodies, and other clothing.
