Differences in Principle: Temperature Dictates the Technical Approach
Thermal transfer is akin to applying a "temporary tattoo"-a design is transferred from a sheet onto the surface of a cup using moderate heat (around 130°C). High-temperature transfer, by contrast, is a "ceramic firing" process; it requires sintering in a kiln at temperatures exceeding 800°C, which fuses the ink with the glaze. The former relies on the adhesive properties of a film, while the latter achieves penetration of the pigments at a molecular level.
Finished Product: A Trade-off Between Durability and Detail
Thermal Transfer: Offers vibrant colors but is prone to wear; ideal for short-term use or complex, gradient-heavy designs.
High-Temperature Transfer: Creates a protective, glass-like layer that is scratch-resistant, washable, and microwave-safe; however, the color palette is more restrained due to the limitations of the glaze.
Tactile Experience: Thermal transfer leaves a noticeable film-like texture, whereas high-temperature transfer becomes fully integrated into the cup itself.
Selection Guide: Choosing the Right Method for Your Needs
For event souvenirs, opt for thermal transfer: it is cost-effective and offers fast turnaround, making it perfect for one-off promotional needs.
For daily use, choose high-temperature transfer: the design will not fade even with prolonged soaking, and it is fully dishwasher-safe.
A Note on Specific Designs: Thermal transfer is better suited for gradients, while high-temperature firing is the preferred choice for single-color logos.
