Sublimation printing is a digital printing method that uses heat to transfer dye onto various materials, such as polyester fabrics or specially coated items. The process involves printing the design onto a sublimation transfer paper with specialized sublimation inks. The paper is then placed on the material and subjected to heat and pressure, causing the ink to vaporize and penetrate the surface of the material. As the ink cools, it solidifies, resulting in vibrant, durable, and fade-resistant prints that become a part of the material itself. Sublimation printing offers a wide color gamut, excellent color reproduction, and the ability to print intricate details, making it popular for creating personalized apparel, promotional items, signage, and more.
