What Exactly Is Sublimation?

Sublimation is a printing process where a special type of ink turns from a solid to a gas back to solid when heated, completely skipping the liquid stage.

When sublimation ink is pressed onto a polyester surface at high heat:

1. The ink becomes gas

2. The polyester fibers open up

3. The gas dye infuses into the material

4. Everything cools and the ink becomes solid inside the fibers

The result?

 A permanent, vibrant design that will never peel, crack, or fade with smooth, professional-quality results.

This is why sublimation is so popular for products like mugs, shirts, signs, and home decor.

What Can You Sublimate Onto?

Sublimation only works on polyester or poly-coated surfaces.

1.  Fabric with at least 65% polyester

(100% polyester gives the brightest, sharpest results)

      2. Hard surfaces with a polymer coating, such as:

• Ceramic mugs

• Metal panels

• Ornaments

• Acrylic blanks

• Tumblers

• Coasters

• Keychains

• Sublimation cutting boards

• Phone stands

     3.Hard surfaces that have been treated with a special sublimation coating

Meaning you buy the blank pre-coated, you can’t just sublimate onto any random wood or glass without prep work first. 

What you cannot sublimate onto (without special hacks):

• Cotton

• Wood

• Canvas

• Dark-colored items

• Regular mugs from Walmart or Dollar Tree

• Anything without polyester

But don’t worry because there are methods to sublimate on cotton, wood, and canvas using coatings or special materials. You can check that out HERE.

Why Do Sublimation Colors Look Dull Before Pressing?

Beginner crafters are always surprised by this:

Sublimation prints look faded, dull, or washed-out BEFORE heat is applied.

This is normal.
The ink is activated by heat and becomes bright, bold, and saturated during pressing.

If your print still looks dull AFTER pressing, that’s when troubleshooting is needed, you can find out more about that HERE.

What Equipment Do You Need for Sublimation?

Here’s a simple beginner checklist.

1. A Sublimation Printer

You have two options:

A. Convert an Epson EcoTank printer
The cheapest option, and most common for beginners. I also have a guide on how to convert an Epson Ecotank if you would like to learn how to do it yourself. 

B. Buy a dedicated sublimation printer
Sawgrass is a good option, it's more expensive but plug-and-play and ready out of the box. 

You must use sublimation compatible ink because regular printer ink does not work.

---

2. Sublimation Ink

Bottled or cartridge-style ink formulated specifically for sublimation.

Good beginner brands:

• Hiipoo

• Printers Jack

---

3. Sublimation Paper

Not regular printer paper.
Sublimation paper is designed to hold dye on the surface for clean transfer.

A-Sub is the most popular and beginner-friendly brand or Hipoo.

---

4. Sublimation Blanks

These are the objects you print on.
Examples:

• Shirts

• Tumblers

• Mugs

• Keychains

• Puzzles

• Canvas sheets

• Photo slates

Make sure they say “sublimation blank” or “poly-coated.”

---

5. Heat Source

You can use:

• A heat press

• A Cricut easypress

• A tumbler press

• A mug press

• A convection oven (for crafts ONLY —the oven is not food-safe afterwards)

Cricut EasyPress works for shirts, but not ideal for hard blanks.

---

6. Heat-Resistant Tools

You’ll also need:

• Heat tape

• Butcher paper

• Heat gloves

• Teflon sheet (optional)

---

How Does the Sublimation Process Work? 

Here’s a quick overview of what the entire process will look like and what actually happens.

1. Print your design on the sublimation paper

•  Make sure to MIRROR it.

2. Tape the design to your blank

• Prevents ghosting or blurry shadows.

3. Press the design to the blank under heat

•  Usually 385–400°F for 45–60 seconds.

4. The ink will turn into gas

•  Transfers into the polyester coating.

5.The design becomes permanent

• No peeling, no cracking, no fading.

It becomes part of the material.

Common Questions

Do I need a special printer?

Yes, sublimation requires a sublimation printer or a converted Epson.

Can I use my regular inkjet or laser printer?

No.
Sublimation ink will not work in those printers.

Can I sublimate on cotton?

Not directly.
You need:

• Glitter HTV

• Sublimation patches

• Sublimation coating spray

You can check out how to do that HERE. 

Do sublimation prints fade in the wash?

Not if applied correctly and used on polyester.

Why is my black printing brown?

Heat too high or press too long.

Tips for Beginners

• If you’re brand new, start with polyester shirts. They’re the easiest to learn on.

• Avoid mugs until you have the right press. Not all heat sources work for ceramic.

• Don’t buy random blanks from Walmart. They usually aren’t poly-coated.

• Make sure your heat press is accurate. Use an infrared thermometer if needed.

• Always place butcher paper under your blank. Sublimation ink can bleed through.

---

What Projects Are Best for Beginners?

Start with:

• Bookmarks

• Keychains

• Polyester zip pouches

• Sublimation coasters

• Aluminum ornaments

• Garden flags

• Mousepads

These are forgiving and press beautifully.
