Introduction to Sublimation Printing
Before we dive into the causes of fading, it is essential to understand the sublimation printing process. Sublimation printing is a technique that involves transferring dye onto a substrate, such as ceramic, glass, or fabric, using heat and pressure. The dye is embedded into the substrate, creating a permanent and full-color image. This process requires a sublimation printer, sublimation ink, and a heat press.
The Sublimation Process
The sublimation process involves several steps, including printing, drying, and pressing. During the printing process, the sublimation ink is applied to a transfer paper. The transfer paper is then placed on the substrate, and the combination is subjected to heat and pressure using a heat press. The heat causes the ink to sublimate, or change directly from a solid to a gas, which then bonds with the substrate, creating a permanent image.
Factors Affecting the Sublimation Process
Several factors can affect the sublimation process, including the type of substrate, the quality of the sublimation ink, the temperature and pressure of the heat press, and the duration of the pressing time. If any of these factors are not optimized, it can lead to a poor-quality print that may fade over time.
