A dye sublimation printer is a type of printer that uses heat to transfer dye onto materials such as fabric, plastic, or paper. This process involves turning solid dye into gas without passing through a liquid state, allowing the dye to bond with the surface of the material. The result is vibrant, high-quality images that are durable and resistant to fading. These printers are commonly used for creating photo prints, custom apparel, and promotional items. They are popular in industries like photography and textile printing due to their ability to produce detailed and colorful designs.
