Sublimation is a printing process where a design is printed onto a transfer paper with sublimation ink and then transferred onto a substrate, such as fabric, using a heat press. This printing process is commonly used on polyester or polyester-blend materials, but can also be used on other materials such as ceramics, metals, and plastics.

The ink used is a special type of ink that turns into a gas when exposed to heat and pressure. When the transfer paper with the design is placed onto the substrate and heated with the heat press, the ink turns into a gas and bonds with the fibers of the substrate, creating a permanent, full-color design.

Sublimation printing is popular in the garment industry for creating custom designs on T-shirts, jerseys, and other apparel. It offers high-quality, long-lasting prints that are fade-resistant and won’t peel or crack. The process is also environmentally friendly, as it doesn’t produce any waste or use harsh chemicals.

However, sublimation printing is limited to light-colored or white materials, as the ink is transparent and won’t show up on darker colors. Additionally, sublimation printing requires specialized equipment and materials, making it more expensive than other printing methods.
