How to Understand Sublimation Transfer Paper?

Even though sublimation is traditionally printed with an inkjet printer, the chemical properties of the ink (which is actually a dye) are radically different from pigment-style inks, thus the paper is uniquely engineered for the process.

While standard inks require a form of bonding agent to adhere to the surface of the fabric, sublimation dyes physically penetrate, bond, and re-color polymer fibers. Because of the molecular process, binding agents are not required. Thus, sublimation transfer paper is composed of a polymer management layer combined with a release agent.
Unlike inkjet and laser transfer papers, the entire surface of sublimation paper does not transfer, as there are no binding agents involved. The sublimation dye simply turns into a gas during the pressing phase of the process and transfers into the polymer fibers of the substrate. Also, since sublimation is sub-surface, it has no hand.

One new development with sublimation transfer products is “tacky paper” (currently only available in roll form). Tacky sublimation paper is manufactured with a light adhesive within the surface and is ideal for preventing ghosting that happens if the paper shifts when releasing the heat press. Those that lack the ability to print on rolled media can apply a very light coating of spray adhesive to the transfer for the same effect.

The variety of sublimation papers may look similar, but different brands have different manufacturing recipes. It pays to explore the options on the market. Don’t focus on cost, but look for the product that consistently delivers the highest quality images.
Note that sublimation dyes do not work with non-poly fibers.
