Sublimation printing is a process where a design is transferred from special paper to a material (like fabric, ceramic, or metal) using heat and pressure. The key is that dye sublimation ink transforms from a solid to a gas without becoming a liquid, and this gaseous ink then binds with the material's fibers, creating a permanent, vibrant image.

To care for sublimation tumblers, hand wash them with mild dish soap and a soft sponge, avoiding abrasive scrubbers. Don't use the dishwasher, microwave, or expose them to extreme heat, as these can damage the print or coating. Properly store them in a cool, dry place.
