how to do sublimation
Sublimation is a way to turn solid ink into a gas with heat and pressure so it permanently dyes polyester surfaces like shirts, mugs, and tumblers.
What sublimation is (in simple terms)
Sublimation ink starts as a solid on special paper, then turns into a gas when heated and bonds with polyester fibers or a polyester coating.
Unlike vinyl that sits on top, sublimation becomes part of the material, so designs feel smooth, don’t peel, and stay vibrant for a long time.
What you need to do sublimation
To get started at home, most people use:
- Sublimation printer (often a converted inkjet or a dedicated sublimation printer) with sublimation ink.
- Sublimation paper designed to hold and release sublimation ink properly.
- Heat source: a heat press (clamshell or swing-away), tumbler press, or convection oven for mugs and drinkware.
- Blanks: polyester shirts (usually 65–100% polyester), coated mugs, tumblers, keychains, mousepads, etc., all specially labeled as “sublimation blanks.”
- Design software or app (any tool that can size and mirror images, like basic graphic or crafting software).
- Heat-resistant tape, butcher paper or parchment, and a heat-resistant mat or pressing pad to protect your surfaces.
Step‑by‑step: how to do sublimation on a shirt
Here’s a beginner-friendly walkthrough using a polyester T‑shirt:
- Choose and prepare your design
- Create or buy a high-resolution design sized to your shirt and print area.
* Mirror (flip) the image before printing, especially if it has text.
- Print the design on sublimation paper
- Load sublimation paper correctly (print on the bright/rough side as directed by the package).
* Use your sublimation printer with the correct settings (paper type, print quality, and color profile if available).
- Prepare the shirt
- Use a light-colored, high-polyester shirt; 100% polyester gives the most vibrant results, while poly blends look more “vintage.”
* Pre‑press the shirt for a few seconds to remove moisture and wrinkles.
- Position the transfer
- Place a piece of butcher paper or plain parchment inside the shirt to prevent ink bleed-through.
* Lay the printed design face down on the shirt where you want it, and secure it with heat-resistant tape so it doesn’t shift.
- Press with heat
- Typical settings for shirts are around 380–400°F (about 193–204°C) for 40–60 seconds, but always check the blank manufacturer’s instructions.
* Apply firm, even pressure and keep the press closed for the full time without lifting or sliding.
- Remove and cool
- Open the press carefully and peel the paper off while it’s still hot or as recommended by the product.
* Let the shirt cool flat; the design should now be fully infused into the fibers and feel completely smooth to the touch.
Key tips and common beginner mistakes
- Use the right material: sublimation only works properly on polyester fabrics or polymer-coated hard blanks; cotton will look faded and wash out.
- Stick to light colors: sublimation ink is transparent, so it shows best on white or very light backgrounds and doesn’t work well on black garments.
- Avoid ghosting: tape the paper securely and don’t move the press during or immediately after pressing.
- Protect your press: always use butcher paper above and below your project so stray ink doesn’t transfer to the press or other items.
- Test first: many crafters do small test presses on scrap fabric or cheap blanks to dial in time and temperature.
Other popular sublimation projects
Once you understand how to do sublimation on shirts, the same basic steps work for:
- Mugs and tumblers: print, wrap, tape firmly, then heat in a mug or tumbler press or compatible convection oven for the recommended time.
- Mousepads and keychains: usually press flat like shirts, with similar temperature but often shorter times (follow the blank’s instructions).
- Home décor: pillows, photo panels, metal prints, and more, as long as they’re sold as sublimation-ready blanks.
