Printing on polyester and blends lasts when the method suits the fibre: DTF and sublimation can bond with polyester, while DTG's water-based ink is not recommended on it because synthetic fibres repel water-based ink. On blends you also have to watch three things, adhesion, dye migration from coloured polyester and stretch, and the care instructions you give buyers decide much of how long the print survives.
This matters more than many sellers expect, because a lot of "cotton" blanks are partly polyester in some colours, and sweatshirts and hoodies usually are blends. If you sell heather tees, crewnecks, hoodies, performance shirts or all-over print items, the fabric label should shape both the print method and what you tell buyers.
Why fibre content changes the print
Cotton is a natural fibre that absorbs water-based ink. Polyester is synthetic: water-based ink sits on it poorly, but it takes sublimation dye when heated. A blend behaves like a mix of the two, and the larger the polyester share, the more it acts like polyester.
Check the spec sheet for every colour, because content changes within one style:
Gildan 5000 is "5.3-ounce, 100% US cotton", but Ash is 99/1, Sport Grey and the Antique colours are 90/10, and the heathers (such as Dark Heather and Graphite Heather) and the Safety colours are 50/50 cotton/polyester.
Gildan 64000 heathers such as Heather Navy and Dark Heather are 65/35 polyester/ring spun cotton.
The Gildan 18500 hoodie is "8-ounce, 50/50 cotton/poly", and its heathers are 60/40 polyester/cotton.
Our comparison of cotton, polyester and tri-blend shirts covers how these fabrics feel and wear.
Adhesion: how each method holds on synthetic fibres
DTG
DTG "works like an inkjet printer, spraying water-based ink directly onto a garment", and one provider says it needs 100% cotton or high-cotton garments and is not recommended for nylon or polyester, because "synthetic fibers repel water-based ink." Another calls DTG best suited to natural fabrics such as cotton, bamboo, linen and blends of them. That is why DTG is usually kept for cotton and high-cotton blanks.
DTF
DTF prints the design onto a film, coats it with adhesive powder and heat-presses it onto the garment. The same provider says "DTF can print on cotton, polyester, nylon, and blends alike", and a white ink layer on the film lets it work on any fabric colour. Because the print is held by adhesive rather than absorbed, DTF is usually the most forgiving choice for 50/50 and polyester-rich blanks. Our guide on what DTF printing is and how it works explains the process.
Sublimation
Sublimation uses high heat and pressure to apply dye that soaks into the material, and it "requires polyester or another synthetic material". Cricut, writing about its sublimation-style Infusible Ink, gives at least 75% polyester as the minimum for preferred results and says the designs will not transfer to 100% cotton. On a 50/50 blend, only the polyester part takes the dye, so the print looks paler. See why sublimation needs polyester and light surfaces.
Which method suits which fabric
| Fabric content | Example blanks | DTF | DTG | Sublimation |
|---|---|---|---|---|
| 100% cotton | Most Gildan 5000 colours, Comfort Colors 1717 | Works | Works well | Does not transfer |
| High-cotton (99/1, 90/10) | Gildan 5000 Ash, Sport Grey | Works | Works | Not suitable |
| 50/50 cotton/polyester | Gildan 5000 heathers, Gildan 18500 | Works | Check with your provider | Pale, faded look |
| Polyester-rich (60/40, 65/35) | Gildan 18500 heathers, Gildan 64000 heathers | Works | Not recommended | Below the 75% guide |
| Mostly or fully polyester | Performance and all-over print items | Works, watch dye migration on bright or dark colours | Not recommended | Works on white or light colours |
Dye migration on coloured polyester
Dyed polyester has a habit cotton does not: when the garment is heated during pressing or curing, some of the fabric's own dye can move up into the print. It shows as a tint in white or light areas, for example white lettering on a red polyester shirt turning slightly pink. It is mainly a risk on bright or dark polyester-rich garments printed with heat-applied methods.
Printers have their own ways to limit it, such as lower press temperatures or blocker layers, but the simplest step is yours: before you list a coloured polyester blank, ask your production partner whether they print on it and order a sample. Sublimation sidesteps coloured fabric altogether, because it is used on white or light material. Cricut says Infusible Ink works with white or light-coloured fabrics, and on all-over print products "the color white can't be printed".
Stretch and wear
A print that sits on top of the fabric has to flex with it. DTF leaves "a thin, smooth layer you can feel sitting on top of the fabric", firmer at first and softer after the first few washes, according to one provider. Another notes a slightly stiff, plastic feel at first and low breathability. On stretchy performance fabric, sizing the design sensibly and avoiding heavy solid blocks across areas that stretch helps it last.
All-over sublimation has its own stretch issue. The design is printed over white material, so dark backgrounds can show white lines when the fabric stretches.
Heat is the other enemy. A DTF print "might develop small cracks if the garment is washed in hot water". Providers quote rough lifespans (one estimates DTF holds up for 50 to 100 washes before fading, cracking or peeling shows), and real results depend on how the garment is washed. Our guide on why prints crack or peel covers the causes.
What to tell buyers about care
How a buyer washes and dries the garment has a big effect on the print, so put care instructions in the listing description and, if your partner allows it, on an insert. Keep them short:
Turn the garment inside out.
Wash cold or cool with similar colours.
Tumble dry low or hang dry.
Do not iron directly on the print.
Our guide on how to wash and care for DTF printed shirts goes into more detail.
Manufacturers write their own care rules too. The Comfort Colors 1717 sheet says "Maximum washing temperature 30C, inside out, with like colors" and "Do not iron."
Describe the fabric accurately per colour as well. "100% cotton" is wrong for a heather that is 50/50, and Etsy Purchase Protection does not cover cases where "the item doesn't match the listing description".
How Alomations handles fabric and print method
The products in the Alomations catalog are printed with DTF for apparel, plus sublimation for the products that need it, and production for US orders is in the US. The catalog covers Gildan, Bella+Canvas and Comfort Colors apparel, performance polos and tees, mugs, tumblers, tote bags and more, each with a "from" price listed.
On the listing side, the copy a run writes keeps fabric claims in line with the materials in your template, so a blend is not described as pure cotton, and a long-sleeve shirt is never called a "tee".
Frequently asked questions
Can you print on 100% polyester shirts?
Yes, with DTF or sublimation. Providers do not recommend DTG on polyester, because synthetic fibres repel water-based ink.
Why does sublimation look faded on my blend shirt?
Only the polyester fibres take the dye. For its sublimation-style Infusible Ink, Cricut gives at least 75% polyester as the minimum for preferred results and says it does not transfer to 100% cotton.
Is DTF durable on 50/50 blends?
It can be. DTF prints on cotton, polyester and blends alike, and one provider estimates 50 to 100 washes before wear shows. Cool washes and no direct ironing on the print help it last.
Where should care instructions go?
In the listing description, where buyers read them before buying, and on a package insert if your production partner offers one.
