How to sublimate a shirt comes down to one thing more than any other: the fabric. In direct garment sublimation, heat turns the dye into a vapor that diffuses into polyester and stays there as the shirt cools, so a bright, wash-resistant print starts with the right blank and ends with the right press settings. This guide walks you through your first shirt from start to finish, using a standard white or light polyester tee as the example, and points you to the right place when your shirt is dark or a blend.
My Quick Answer
To sublimate a shirt, print your mirrored design onto sublimation paper, tape it face-down onto a white or light 100% polyester shirt, and press at around 385°F (196°C) for 45 to 50 seconds with medium pressure. Pre-press the shirt for a few seconds first to drive out moisture, then lift the paper straight up once the press opens. These are a starting point, not a universal standard; some systems specify closer to 400°F, so follow your garment, ink and paper instructions.
Untreated cotton does not retain conventional sublimation dye reliably; it may show color immediately after pressing, but much of that color is lost during washing. Dark shirts need a workaround because sublimation ink is transparent and cannot print white.

Faded, patchy or ghosted results usually come from a short list of causes: the wrong fabric, moisture, incorrect time or temperature, uneven pressure, transfer movement, a clogged nozzle, or an incorrect print and color workflow. Get the main ones right and sublimation on polyester is one of the most durable print types a home crafter can make. Let us go through it in the order you will actually do it.

What You Need to Sublimate a Shirt
Your shopping list is short and, apart from the printer, inexpensive. You need a sublimation printer with sublimation ink (a converted Epson EcoTank or a dedicated Sawgrass are the two common routes), sublimation paper, heat-resistant tape, a heat press, a lint roller, and clean butcher or plain copy paper to protect your press. For choosing the machine itself, my best sublimation printer for beginners guide breaks down the options honestly.
One thing worth saying up front: a household iron is not a heat press. It cannot hold controlled, even temperature and pressure across a typical shirt design, so results are hard to reproduce and often uneven. A basic flat press is the single upgrade that makes the biggest difference to your results.
A word on the protective paper: use clean, uncoated butcher paper or clean unprinted copy paper. Place one fresh sheet inside the shirt and another over the transfer. Do not use waxed paper, freezer paper, printed paper, or a sheet that already holds transferred dye, and swap in fresh paper for each press.

- Butcher Paper – protects the press from stray sublimation dye.
Which Shirt to Buy: Polyester Is Everything
This is the step that decides your result before you ever turn the press on. In direct garment sublimation, the dye volatilizes under heat and diffuses into polyester fibers, where it remains once the fabric cools. Untreated cotton does not retain conventional sublimation dye permanently. It may look stained right after pressing, but much of that color is lost in the wash. The higher the polyester content, the more of the fabric can hold the dye, so the print is usually brighter and more complete; lower-polyester blends start out more muted because the cotton fibers stay largely undyed.
Use this as your quick buying reference:
| Shirt Type | Result | Best For |
|---|---|---|
| 100% polyester | Brightest, sharpest, generally most wash-resistant | Everyday wear, gifts, selling |
| 65% polyester / 35% cotton | Softer, muted, vintage look | The trendy faded aesthetic |
| 50% polyester / 50% cotton | Noticeably faded, distressed finish | Retro designs only |
| 100% cotton | Not reliably wash-durable with direct sublimation | Needs a workaround (see below) |
A 100% polyester label is a strong starting point, but it does not guarantee that every garment tolerates the same press cycle. Performance finishes, stretch fibers, garment dyes and textured surfaces can all react differently, so check the supplier’s decoration instructions and test a spare garment when you can.
Color matters as much as fiber content. Sublimation ink is transparent and has no white, so the shirt color shows through your design. White shirts provide the least color interference and usually give the most accurate, vibrant reproduction. Very light colored shirts can also work, but their color still influences the final design. On a colored shirt, every part of your design mixes with the shirt underneath. Colored polyester can also experience dye migration or heat discoloration, where the garment’s own dye moves into your design under heat. Test a hidden area before pressing, especially on red, navy, black and performance garments. For your first few shirts, stick to white 100% polyester so you can judge your settings without the fabric fighting you.
How to Sublimate a Shirt Step by Step
Here is the full process for a standard white or light polyester tee. Once this feels natural, every variation is a small tweak on the same routine.
1. Size and mirror your design. Set your design to the finished print size and flip it horizontally. A common adult front design runs around 10 to 11 inches wide, but that needs a printer and paper wide enough for it. A standard US-letter printer is limited to a narrower one-piece image unless you tile the transfer. Forgetting to mirror is a common beginner mistake, especially with text or directional artwork. If you forget, your words come out backwards.
2. Print onto the coated side of your sublimation paper. Sublimation paper has a printable side and a back. Print your mirrored design through your printer’s color-managed workflow. Sublimation prints usually look duller on paper than they will after pressing, so do not judge color from the printout. If a properly pressed test still looks off, check the nozzle pattern, ink and paper compatibility, driver settings and your sublimation ICC profile workflow. The best sublimation papers guide covers which paper suits your setup.
3. Lint-roll and pre-press. Check the garment label and the supplier’s decoration instructions for heat-sensitive finishes, water-repellent treatments or pressing restrictions, and inspect the shirt for damage and debris. Then lint-roll the print area carefully before heating, since loose fibers, dust and debris can create permanent blue or dark specks. Pre-press the bare shirt for a few seconds to flatten it and remove moisture that could cause pale, uneven or hazy transfers. After pre-pressing, inspect the area again and remove any visible debris once the fabric is safe to handle.
4. Position and tape the transfer face-down. Lay the paper printed-side down where you want the design, and secure it with enough heat-resistant tape to stop it moving, keeping the tape away from the printed area where possible. Any movement mid-press shows up as ghosting, a faint double image.
5. Protect the press. Slide a clean sheet of butcher or copy paper inside the shirt so dye cannot reach the back, and lay another fresh sheet over the transfer to protect the top platen.
6. Press at around 385°F for 45 to 50 seconds, medium pressure. Treat this as a starting point for white 100% polyester, not a fixed standard. Published instructions vary by garment, ink, paper and press; some systems specify closer to 400°F for about 45 seconds. Keep collars, seams, buttons and thick hems outside the pressing area where you can, or use a pressing pad so they do not block even contact.
7. Open the press and lift the paper. Unless your paper or garment instructions say otherwise, lift the transfer paper straight up promptly after opening the press. Do not slide it across the hot fabric, because movement can cause ghosting. Let the shirt cool before you fold or stack it.
Sublimation Shirt Settings by Fabric Type
Most guides bury the numbers inside a paragraph. Here they are in one place, drawn from our own sublimation temperature chart. Treat every value as a starting point, not a guaranteed recipe: fabric, dye, paper, ink and press all vary, so test before you press a full batch and follow the supplier’s instructions whenever they exist.
| Fabric | Temp (start) | Time (start) | Pressure | Note |
|---|---|---|---|---|
| 100% polyester | 385°F (196°C) | 45-50 sec | Medium | Starting point; some systems specify up to about 400°F. Pre-press to remove moisture |
| 65% polyester / 35% cotton | Around 385°F (196°C) | Around 45 sec | Medium | Test value only; follow the exact garment supplier’s instructions. Expect muted color and check for heat sensitivity and dye migration |
| 40% polyester / 60% cotton | No universal setting | Product-specific | Product-specific | Mostly cotton, so direct sublimation produces a pale, distressed result. Follow the garment supplier’s instructions and test a spare shirt before pressing |
A key point beginners miss: more cotton does not automatically mean less time or heat. The polyester portion still needs enough heat to take the dye, so simply shortening the press can leave a weak transfer, while the garment’s dye and construction may instead call for a lower-temperature test. Read fiber content carefully, too, since 65/35 usually means 65% polyester but 60/40 cotton-poly means only 40% polyester. If you want the reasoning behind each dial, our sublimation printer settings guide explains what temperature, time and pressure each do, and Sawgrass publishes its own product-specific apparel settings in the official resource center.
Medium pressure means firm, even contact rather than maximum force, and the exact setting varies by press. Use only enough pressure to keep the whole transfer in uniform contact with the shirt, and account for seams, collars and raised areas.

What If Your Shirt Is Dark or a Blend?
This is where a lot of first projects go wrong, so it is worth knowing before you buy blanks.
Dark shirts are the big one. Because sublimation ink is transparent and cannot print white, a design pressed straight onto a black shirt will usually be effectively invisible. On other dark colors, some darker image areas may still show, but the design is severely altered because there is no opaque light base. No press setting fixes this; it is how the ink works. The real fix is a transfer product specifically approved for sublimation ink, such as Siser EasySubli, or a different decoration method such as suitable HTV or DTF. Do not assume every white printable HTV accepts sublimation ink; many are made for other ink types. EasySubli also has its own print, cut, mask and press workflow (Siser lists about 310°F for 15 seconds at medium pressure with a hot peel), so it is not applied with the direct-polyester shirt settings in this article. I walk through the dark-garment methods step by step in the sublimation on dark shirts guide.
Blends generally become more muted as the cotton percentage increases, because conventional sublimation dye is retained mainly by the polyester portion. The exact result can still vary with the garment’s construction, color and finish. Many crafters use this vintage look on purpose for a soft retro finish. If you are working with a 50/50 or similar blend, the sublimation on 50/50 guide covers the exact look to expect and how to lean into it.

Sublimation Shirt Troubleshooting
When a shirt comes out wrong, the fix is usually simple once you match the symptom to the cause. Change one variable at a time so you can tell what actually helped.
| Problem | Likely Cause | Fix |
|---|---|---|
| Faded or dull colors | Low polyester content, wrong paper side, nozzle or color problem, moisture, weak contact, or too short a press | Verify the fiber label, run a nozzle check, confirm the printable side and color workflow, then check press temperature and contact |
| Ghosting (faint double image) | Transfer shifted during pressing or removal | Tape enough to stop movement; open the press cleanly; lift the paper straight up |
| Yellow or brown discoloration | Excessive heat or time, scorching, contamination, or a heat-sensitive garment finish | Stop pressing production pieces; test a lower temperature or shorter time on a spare or hidden area |
| Patchy or uneven print | Uneven pressure, often from an iron, seams or a worn press | Use a flat press; check for even contact; keep seams out of the press area |
| Design comes out backwards | Image was not mirrored | Flip horizontally before printing |
Two of these have their own deep-dive guides when the quick fix is not enough: how to remove sublimation ghosting and, if the design barely transferred at all, why your sublimation is not transferring.
The Honest Truth About Sublimating on Cotton
You will see a lot of hacks that promise to make sublimation work on cotton: polyester coating sprays, glitter HTV bases, and so on. Here is the honest version, because it saves you wasted blanks. Direct sublimation on untreated 100% cotton does not produce a reliably wash-durable print; the dye has no polyester to settle into, so the shirt may show color right after pressing but loses much of it in the wash. Coating sprays can give a printable result, but the finish and wash durability are inconsistent, so I would not rely on them for anything you sell. One reliable option for cotton or dark fabric is a sublimation-compatible transfer material such as EasySubli, which the dark shirts guide covers. Other suitable decoration methods include conventional HTV, DTF and screen printing. If you want a durable print on cotton, direct sublimation is the wrong process; suitable alternatives include HTV, DTF and screen printing.
Washing Your Sublimation Shirt
Sublimation on polyester holds up well because the dye lives inside the fibers rather than sitting on top as a separate layer, so there is nothing to crack or peel. Direct sublimation does not need a universal 24-hour curing wait; once the shirt has pressed and cooled, the transfer is complete. After it cools, wash it according to the garment’s care label. Washing inside out with a mild detergent and avoiding bleach and excessive dryer heat helps preserve the fabric and overall appearance, even though a correctly sublimated image does not depend on a surface adhesive. If your design used EasySubli or another transfer layer, follow that product’s laundering instructions instead. For the full routine, including a care-card template for sellers, see how to wash sublimation shirts without fading.
Frequently Asked Questions
Can you sublimate on a 100% cotton shirt?
Not with reliably wash-durable results. Conventional sublimation dye is not retained by untreated cotton, so it may show color right after pressing but washes out. For cotton, use a sublimation-compatible transfer like EasySubli, or switch to vinyl or DTF.
What temperature do you sublimate a shirt at?
Around 385°F (196°C) for 45 to 50 seconds at medium pressure is a common starting point for white 100% polyester, though some systems specify closer to 400°F. Treat it as a starting point, pre-press to remove moisture first, and follow the supplier’s instructions.
Do you have to mirror the image for sublimation shirts?
Yes, any time your design has text or a correct orientation. Flip it horizontally before printing, or it will transfer backwards.
Why did my sublimation shirt come out faded?
Common causes are low polyester content, the wrong printable paper side, a nozzle or color-management issue, moisture, weak contact, or too short a press. Confirm the fabric and paper first, run a nozzle check, then check the press before changing one thing at a time.
Can I sublimate a shirt with an iron?
An iron may transfer very small areas, but it cannot give the controlled, even heat and pressure a full-size print needs, so results are patchy and hard to repeat. A flat heat press is strongly recommended.
Can you sublimate on a black shirt?
Not directly. Sublimation ink is transparent and cannot print white, so on black fabric the design is effectively invisible. Use a sublimation-compatible transfer such as EasySubli. The dark shirts guide walks through the methods.
How long do sublimation shirts last?
On high-polyester fabric, cared for well, a sublimation print is highly wash-resistant because the dye remains within the polyester fibers rather than forming a separate surface layer. Poor fabric choice, harsh washing or strong UV exposure shortens that.
