Sublimation blanks are the foundation of every successful sublimation project. Whether you’re creating custom apparel, drinkware, home décor, or personalized gifts, choosing the right blanks is critical for achieving vibrant color, durability, and professional results.

In this buyer’s guide, we’ll explain what sublimation blanks are, how they work, the different types available, and how to choose high-quality blanks for your business or personal projects.

What Are Sublimation Blanks?

Sublimation blanks are specially manufactured products designed to accept sublimation ink through heat and pressure. These blanks are either made from polyester-based materials or coated with a polymer layer that allows sublimation dye to permanently bond to the surface.

Unlike standard products, sublimation blanks are engineered to:

  • Produce bright, accurate colors
  • Prevent fading, cracking, or peeling
  • Deliver long-lasting, professional finishes

How Do Sublimation Blanks Work?

Sublimation blanks work by allowing sublimation ink to infuse into the surface material when heat is applied.

When paired with sublimation ink, transfer paper, and a heat press:

  1. The ink turns into a gas under heat
  2. The gas penetrates the polyester fibers or polymer coating
  3. The design becomes part of the blank itself

This process is what makes sublimation products feel smooth and ensures designs remain durable over time.
