A sublimation T-shirt is a type of garment that has been decorated using a sublimation printing technique. Sublimation printing involves transferring a design or image onto fabric using heat and pressure.

Here’s how the process typically works:

Design Creation: The desired design is created digitally on a computer using graphic design software. This design can include any combination of colors, patterns, and images.

Printing: The design is printed onto special sublimation paper using sublimation ink. Unlike traditional printing methods, sublimation ink turns into a gas when heated without passing through a liquid stage. This allows the ink to bond directly with the fabric fibers.

Transfer: The printed sublimation paper is then placed onto the fabric of the T-shirt. Heat and pressure are applied using a heat press machine, which causes the sublimation ink to transfer from the paper to the fabric.

Cooling: After the transfer process is complete, the fabric is allowed to cool, which helps the ink to set and bond with the fibers.
