If you’ve ever put on a custom tee and thought “this feels amazing” or “why is this print so stiff?”, you’ve already felt the real difference between sublimation and heat transfer. Both methods use heat and pressure, typically with a heat press (often called a t shirt press for apparel), but they create the image in totally different ways. Sublimation (with sublimation paper) turns ink into gas and bonds it into polyester fibers. Heat transfer (with heat transfer paper) moves a printed layer onto the fabric’s surface. That one distinction shapes everything you care about—comfort, breathability, stretch, and how the print survives laundry day.

The simplest way to describe it:

• Sublimation feels like fabric.
• Heat transfer often feels like a thin decal.

With sublimation paper, the design is printed first and then activated in a heat press. Under the right temperature and pressure, the ink bonds with polyester (or a polyester-coated surface). Because the color becomes part of the garment:

• Hand feel: Usually no noticeable edge or film—even for larger designs.
• Breathability: The printed area stays closer to the shirt’s natural airflow.
• Stretch & movement: The image stretches with the fabric, which is why it’s common on performance wear.

What you’ll notice wearing it: less “patch” feeling and less heat buildup under the graphic.

With heat transfer paper, you print the design and then use a t shirt press to bond it onto the fabric as a thin layer. Since you’re adding material to the surface:

• Hand feel: More noticeable—especially with big solid shapes.
• Breathability: Reduced where the transfer sits.
• Stretch & movement: Can flex well, but it’s more prone to micro-cracking on high-stretch areas.
• Edges: More defined, and edges can be the first place to lift if pressing is off.

What you’ll notice wearing it: small logos are usually fine; large front prints can feel warmer and stiffer.

Your garment choice matters as much as your pressing setup.

• Sublimation paper performs best on white or light-colored polyester. On cotton, the colors usually look muted because the dye can’t properly bond with the fibers.
• Heat transfer paper is often chosen for cotton tees and dark shirts, because the transfer layer can sit on top of the fabric and remain visible.

Laundry is where these methods separate fast—especially if you use high heat.

Because sublimation becomes part of the fabric (instead of a surface layer), it won’t peel—but it can fade if abused.

Do:

• Wash inside out
• Use cold to warm water and mild detergent
• Air dry or tumble dry low

Avoid:

• High-heat drying
• Chlorine bleach or harsh oxidizers

Heat transfer prints are bonded layers, so you’re protecting adhesion as much as color.

Do:

• Wait ~24 hours after pressing before washing
• Wash inside out on a gentle cycle
• Air dry or tumble dry low

Avoid:

• High-heat drying (can soften adhesives and encourage lifting)
• Ironing directly on the print (iron from the inside or use a protective sheet)

If you want the most “no-feel” print for light polyester apparel, sublimation using sublimation paper and a stable heat press is hard to beat. If you need cotton compatibility or dark-shirt coverage, heat transfer paper applied with a t shirt press is the practical choice—just plan on a more noticeable feel and gentler wash habits to prevent cracking or edge lift.
