Sublimation printing is a process that uses heat and pressure to transfer solid dyes into a gas, which then permeates the surface of a specially coated substrate, such as fabric, ceramics, or metals, and solidifies to create a vibrant and durable photo image. Sublimation is unlike any other printing process. It is not a topical application process and there are no adhesive qualities. The sublimation ink is actually a dye that is transferred through heat and direct contact with a polymer-coated item, or an item made of polyester. The ink is then chemically bonded to the product and the "ink" cannot be felt so it will not scratch off. Once a product is sublimated, the image remains indefinitely. It is a popular method used for creating high-quality, full-color prints on a wide range of products. Sublimation print projects include custom apparel, promotional products, sports jerseys, home decor, personalized gifts, flags, and banners due to its ability to produce prints with rich colors and excellent durability even in outdoor environments.
