Sublimation is a little more complicated than simple heat transfer vinyl. But don’t let that scare you! Sublimation ink, when heated, turns into a gas that actually embeds itself into anything with a polyester coating. This creates a cleaner, more professional look while allowing for a much more detailed image than what heat transfer vinyl can offer. Shading, gradients and a rainbow of colors are huge benefits to using sublimation transfers. There is no difference in feeling between the image and the shirt. Sublimation must be used with at least 50% polyester (white or light colored garment) but will show better results the closer to 100% polyester your garment is (white or light colored garment). The higher the polyester content, the brighter and clearer your image will be. The lower the polyester content, the more vintage, faded or aged your image will be. Also, with a lower polyester content, you may see your image fade slightly with the first wash.
