Sublimation printing is a digital printing technology, also known as thermal transfer printing. The working principle is to use heat energy and pressure to transfer dyes to different materials.

Sublimation printer produce prints that are more durable and less prone to fading than inkjet printer.

Sublimation printing transfers the dye into the substrate rather than depositing it on the surface, so the resulting image is more permanent.

Sublimation printing works by converting solid dyes directly into a gas when exposed to high temperatures, and then ejecting the gas onto the print medium.

So when the fabric is heated, the dye sublimates, turns into a gas, and fuses directly into the fabric. When the dye is embedded in the actual fibers, it creates a permanent print that won’t crack or peel over time.

Generally speaking, images printed with sublimation last longer and are less likely to fade, peel or crack. But in reality, there are many factors that affect the duration of images on fabrics, so the lifespan of DTF images may exceed that of sublimation.

Yes, roller heat press is required for sublimation printing, and the image output is better and more durable after being processed by the roller heat press.
