what is sublimation printing on t shirts ？

 Sublimation printing on T-shirts is a process that uses heat to transfer dye onto fabric—specifically, polyester or polyester-blend materials. Unlike traditional printing methods that place ink on the surface, sublimation bonds the dye into the fibers of the fabric, resulting in vibrant, permanent, and smooth prints.




How Sublimation Printing Works on T-Shirts:

  1. Design Creation
    A digital image or pattern is created using graphic design software.

  2. Printing the Transfer
    The design is printed (mirrored) onto special sublimation paper using sublimation inks.

  3. Heat Press Application
    The printed transfer is placed on the T-shirt and pressed with a heat press (typically at 380–400°F or 193–204°C).
    The heat turns the solid dye into a gas, which then permanently infuses into the polyester fibers.

Benefits:

  • No cracking or peeling – The ink becomes part of the fabric.

  • Soft feel – There’s no added layer, unlike vinyl or screen printing.

  • Vivid colors – Excellent for full-color designs, gradients, and photo prints.

  • Durable – Colors remain vibrant after many washes.

Things to Keep in Mind:

  • Best results are on white or light-colored polyester T-shirts.

  • Not suitable for 100% cotton—the dye won’t bond.

  • Requires sublimation specific equipment, including compatible inks, paper, and a heat press.
