A heat press is a machine used to transfer designs onto various materials, such as fabric, using heat and pressure. It typically consists of two heated plates that press down on the material, allowing the design to adhere effectively. This method is popular for creating custom apparel, like t-shirts, and is widely used in the textile industry. The process involves placing a printed design, often made with a vinyl cutter or sublimation printer, onto the material. The heat press is then closed, applying heat and pressure for a specific time, ensuring the design bonds securely. This technique is efficient and produces high-quality results.
