Whether the ceramic cup can do thermal sublimation treatment？

Yes, ceramic cups can undergo thermal sublimation treatment, also commonly referred to as dye sublimation or heat transfer printing.

Thermal sublimation is a process where dye is transferred from a specially coated paper or film onto a substrate, such as ceramic, through the application of heat and pressure. During this process, the dye is converted from a solid to a gas without going through a liquid state, hence the term "sublimation." This allows the dye to penetrate deeply into the surface of the ceramic, creating a vibrant, long-lasting, and durable print that is resistant to fading, peeling, or cracking.

For ceramic cups, the sublimation process is typically done on white or light-colored unglazed ceramic, as darker or glossy surfaces may not allow the dye to penetrate properly. The ceramic cups are first prepared by cleaning and preheating to ensure optimal adhesion of the dye. Then, the sublimation paper or film with the desired design is placed on the cup, and the entire assembly is subjected to high heat and pressure in a specialized heat press machine.

After the sublimation process is complete, the ceramic cups are allowed to cool and the sublimation paper or film is removed, revealing the permanently printed design. The resulting ceramic cups feature vivid colors and crisp details that can withstand repeated use and cleaning.

Therefore, if you're looking to add a personal touch or a unique design to your ceramic cups, thermal sublimation is an excellent option to consider.
