Yes. Infusible Ink is a relatively new product from Cricut which features a special kind of ink that is set with heat. The ink and the surface become one. Sublimation is actually a scientific term that has to do with the method that a solid becomes a gas, but you don't need to know that. Just know that when someone refers to Sublimation, they are referring to the process of infusing ink into a surface. The ink actually becomes a part of the surface, it does not sit on top of it. You can use Cricut infusible ink on a variety of surfaces. Those surfaces need to be infusible ink-ready.
