Sublimation Printing for Beginners: How It Works and What You Need
Learn how sublimation works, the supplies you need, which shirts and blanks work, and step by step pressing for beginners.
Sublimation pillar for beginners: how it works, supply list, what you can sublimate, step by step shirt pressing, limits and common mistakes.
Sublimation printing uses heat to turn special ink into a gas that bonds into polyester fabric or poly coated blanks, so the design becomes part of the material with no feel on the surface.
Key definition: sublimation
Sublimation ink printed on sublimation paper + heat press heat and pressure + polyester or poly coated blank = a permanent, soft hand print. It works on white or light colors and needs high polyester content.
This is the sublimation pillar of the DAX Learning Hub. If transfers are not bonding, see Heat Transfers Not Sticking: Causes and Fixes.

How Sublimation Works
You print a mirrored design with sublimation ink onto sublimation paper. Under a heat press, the ink turns into a gas and bonds with polyester fibers or a polyester coating. When it cools, the color is locked into the material instead of sitting on top, which is why sublimated prints have no hand and do not crack like a surface layer can.
Two limits follow from that chemistry. The ink only bonds with polyester or poly coatings, so cotton does not hold it well. And sublimation inks are translucent with no white, so they show most clearly on white or light colors.
What You Need to Start Sublimation
| Supply | What to know |
|---|---|
| Sublimation printer | A printer made for sublimation, or a compatible inkjet set up with sublimation ink from the start. A printer that has used regular ink is generally not suitable to switch. |
| Sublimation ink | Dedicated sublimation ink; do not mix with regular inks |
| Sublimation paper | Print on the coated (printable) side |
| Heat press | Even heat and pressure; a household iron is not a substitute |
| Heat resistant tape | Holds the paper in place so it does not shift |
| Protective paper | Parchment or butcher paper to protect the press and garment |
| Blanks | Polyester or high poly shirts, or poly coated hard goods |
| Design software and color profile | Use the color settings or profile your ink and paper supplier recommends |
What You Can Sublimate
- Polyester shirts and fabrics: 100% polyester gives the most vivid result. Blends can work at about 65% polyester or more, with a more faded, vintage look as polyester content drops.
- Poly coated hard goods: mugs, tumblers, metal panels, coasters and similar items made with a sublimation coating.
- White or light colors: sublimation does not print white and does not show well on dark fabric.
Plain cotton, uncoated hard goods and dark garments are not good fits. Plan blank stock with Blank Inventory Sizing and Organization.
How to Sublimate a Shirt Step by Step
- Prepare the design. Size it, use your recommended color settings, and mirror it.
- Print on the coated side of sublimation paper.
- Heat the press. Common starting guidance for polyester shirts is roughly 385 to 400°F (about 195 to 205°C) for about 40 to 60 seconds at medium to firm pressure. Check your ink, paper and blank instructions.
- Pre press the shirt for a few seconds to remove moisture and wrinkles, and lint roll the print area.
- Position and tape the paper face down on the shirt, with protective paper inside the shirt and on top.
- Press for the set time with even pressure.
- Remove the paper promptly, lifting straight up to avoid ghosting, and let the shirt cool.
Sublimation Limits and Common Mistakes
| Mistake or limit | What happens | Fix |
|---|---|---|
| Low polyester or cotton shirt | Faded print that may wash out | Use 100% or high poly blanks |
| Dark garment | Design barely shows | Use white or light blanks |
| Temperature, time or pressure too low | Dull, light colors | Follow supplier settings and verify press heat |
| Printing on the wrong paper side | Weak transfer | Print on the coated side |
| Moisture in the blank | Blotches or uneven color | Pre press first |
| Paper shifting | Ghosting or doubled edges | Tape the paper and lift straight up |
| Wrong color settings | Off or muddy colors | Use the recommended profile and print settings |

Frequently Asked Questions About Sublimation for Beginners (FAQ)
What do you need to start sublimation?
A sublimation printer with sublimation ink, sublimation paper, a heat press, heat resistant tape, protective paper, and polyester or poly coated blanks. Design software and the right color settings help colors print accurately. For press purchase questions, see Heat Press Buying Criteria.
Can any printer be used for sublimation?
No. You need a printer made for sublimation or a compatible inkjet model set up with sublimation ink before any regular ink is used. Sublimation ink is not compatible with every printer, so confirm compatibility with the ink supplier.
What temperature for sublimation?
For polyester shirts, common starting guidance is roughly 385 to 400°F (about 195 to 205°C) for about 40 to 60 seconds at medium to firm pressure. Hard goods often need different times. Follow your ink, paper and blank instructions.
Why are my sublimation colors dull?
Common causes are low polyester content, temperature, time or pressure too low, printing on the uncoated side of the paper, moisture in the blank, and color settings that do not match your ink and paper. Change one variable at a time.
What blanks should a beginner start with?
White or light 100% polyester shirts give the most vivid results, and poly coated hard goods such as mugs and coasters are common first items. See Sublimation Blanks. To turn it into a business, see How to Start a Sublimation Business.
Can you sublimate on dark shirts?
Not directly. Sublimation inks are translucent with no white, so they show most clearly on white or light colors. See Sublimation on Dark Shirts for the options.
Press settings and supplies vary by ink, paper, blank and press; check supplier specs before production.
