Basics of Sublimation Ink

How Sublimation Ink Works

Sublimation ink operates on a unique principle that distinguishes it from other types of printing inks. When heated, sublimation ink transforms from a solid to a gas without passing through a liquid phase.

This process, known as sublimation, allows the ink to penetrate the substrate's surface, creating a permanent, high-resolution image.

The sublimation process involves several key steps:

• The design is first printed onto a special transfer paper using sublimation ink.
• The printed transfer paper is then placed on the substrate, which is typically a polyester or polymer-coated material.
• Heat and pressure are applied, usually with a heat press, causing the sublimation ink to turn into a gas.
• The gaseous ink molecules bond with the fibers of the substrate, resulting in a full-color, durable image that is resistant to fading and cracking.

Sublimation ink is particularly popular for applications where longevity and clarity of the print are paramount, such as in the production of custom apparel, signage, and promotional items.
