The Basics of Sublimation Printing
Sublimation printing is a heat transfer process that involves embedding dye into the fibers of a material, resulting in a permanent, full-color image. This technique requires a few essential components:
- Sublimation ink: A special type of ink that turns into a gas when heated, allowing it to penetrate the fibers of the material.
- Heat press: A machine that applies high pressure and heat to facilitate the sublimation process.
- Sublimation-friendly material: A material that is coated with a polyester or polymer finish, which allows the sublimation ink to bond with the fibers.
The Importance of Material Selection
Not all materials are suitable for sublimation printing. The material must be able to withstand the high temperatures and pressures involved in the sublimation process, and it must have a polyester or polymer coating to allow the sublimation ink to bond with the fibers. Common materials that work well with sublimation printing include:
- Polyester fabrics
- Ceramic mugs
- Metal water bottles
- Glass ornaments

What is sublimation printing?
Sublimation printing is a method of printing that uses heat to transfer dye into materials such as ceramics, glass, and polyester fabrics. The process involves printing the design onto a heat transfer paper, which is then applied to the substrate using heat and pressure. The heat causes the dye to sublimate, or change directly from a solid to a gas, and bond with the substrate.
The beauty of sublimation printing lies in its ability to produce full-color images with vibrant colors and intricate details. The process is highly versatile and can be used on a variety of materials, making it a popular choice for creating customized products such as t-shirts, mugs, and phone cases.
What is a Gildan shirt?
