sublimation printing is a digital printing technique that uses heat to transfer dye onto materials like fabric, plastic, or metal. The process begins with printing a design onto special paper using sublimation inks. When heat and pressure are applied, the ink turns into gas and permeates the surface of the material, creating a vibrant and durable image. This method is popular for creating custom items such as t-shirts, mugs, and phone cases. Unlike traditional printing, sublimation allows for full-color designs and works best on polyester or polymer-coated surfaces, ensuring that the colors remain bright and do not fade easily.
