Sublimation is a textile printing process for light-colored fabrics with a high polyester content. The design is first printed onto sublimation paper using special sublimation ink and then transferred to the fabric using heat and pressure. During this process, the ink transitions directly from a solid to a gaseous state and bonds with the polyester fibers.
Sublimation printing is an attractive option for businesses when they need clothing that is lightweight, functional, and vibrantly colored. The process is particularly well-suited for sports shirts, jerseys, promotional apparel, trade show apparel, teamwear, and all-over prints. The print does not lie on the surface as a noticeable layer but becomes part of the material itself. As a result, the fabric remains pleasantly soft and can still be used for activities involving a lot of movement.
Scientific studies on sublimation transfer printing on polyester examine, among other things, the wash, light, and sweat fastness of printed fabrics, which is particularly relevant for assessing durability.

Why Sublimation Printing Is Often Misunderstood
During consultations, we often encounter two common objections. Many customers ask whether a printed design really lasts as long as embroidery. In addition, there is often concern that textiles with all-over prints are no longer breathable. These questions are understandable, because until now, many companies have been primarily familiar with embroidery, flex printing, or transfer printing.
With sublimation printing, however, no additional film or raised ink layer is created. The dye is incorporated into the polyester fiber through the sublimation process. This is precisely why the process differs significantly from traditional printing and transfer methods. A study published in *Scientific Reports* is helpful for assessing durability: Among other things, the study examined the wash, light, and sweat fastness of sublimation-printed polyester.

How does textile printing work?
Sublimation refers to the process by which a substance transitions directly from a solid to a gaseous state. In the field of sublimation technology, this physical process is used for textile printing. The design is printed onto sublimation paper using sublimation ink. The paper is then placed face down on the fabric and processed using a heat press.
Under specific pressure and temperature conditions, the ink sublimates. It turns into a gas, penetrates the polyester fibers, and is fixed in place after cooling. This distinguishes this printing method from processes in which ink, iron-on film, or transfer material remain on the surface.
This process is particularly well-suited for:
- light-colored polyester fabrics
- Sports and Performance Shirts
- Jerseys and Team Apparel
- Pillowcases containing polyester
- polymer-coated items such as mugs, metal cases, or cell phone cases
For dark cotton, however, classic sublimation is not the right solution.
What are the benefits of sublimation printing for corporate fashion?
This printing method is particularly well-suited for corporate fashion when design freedom and comfort need to be balanced. Color gradients, photographic images, large-scale prints, and custom designs can be reproduced with great precision. Especially for trade show apparel, promotional clothing, or athletic teamwear, an all-over print can make a brand much more visible than a small chest logo.
One major advantage is the feel of the fabric. Since the print isn’t an additional layer on top of the fabric, the textile remains light and soft. When used with suitable polyester fabrics, the result is a durable print that does not tear or peel off like a film. However, durability still depends on the material, ink, printer, pressing time, and finishing process.

Sublimation, embroidery, or transfer printing: Which method is right for you?
Not every printing method is suitable for every application. Embroidery has a high-quality look and is often an excellent choice for polo shirts, dress shirts, jackets, or caps. However, when it comes to large-scale motifs, color gradients, or photorealistic designs, embroidery reaches its technical and economic limits. Sublimation printing offers greater flexibility in these cases.
| Requirement | Sublimation | Embroidery | Transfer printing |
|---|---|---|---|
| All-over print | Very well suited | Not suitable | Not suitable |
| Photo opportunities | Very well suited | Hardly suitable | Depends on the method |
| Feel | barely noticeable | raised | noticeable depending on the material |
| Suitable fabrics | light-colored polyester | Many fabrics | many fabrics |
| Small Logos | Available | very high quality | well-suited |
| Breathability | depends on the fabric | usually unchanged | depends on the transfer material |
For companies, therefore, the key question is not which process is fundamentally better. The key factor is which process is best suited to the material, application, design, and budget.
Do sublimated textiles remain breathable?
The concern that all-over printing automatically compromises breathability is too sweeping. With sublimation, no closed film is applied. This means the fabric is not additionally covered, as is the case with some transfer materials. Nevertheless, the process can alter the physical properties of a textile because heat and pressure are applied to the material.
A scientific study on the air permeability and water absorption of polyester-based knitted and woven fabrics shows that air permeability can decrease after the sublimation process. The study attributes this primarily to structural changes caused by temperature and pressure, rather than to the dye itself.

In practice, this means that breathability depends on the fabric, the construction, the print design, and the process parameters. Therefore, selecting the right materials remains crucial.
Which textiles are suitable for sublimation printing?
Sublimation printing works exclusively on white or light-colored textiles with a high polyester content. Polyester fibers can absorb the gaseous dye and bind it permanently. Cotton reacts differently, which is why traditional sublimation cannot be used on pure cotton. Dark textiles are also problematic because sublimation does not produce a white background.
Suitable applications include performance shirts, running shirts, jerseys, team apparel, lightweight trade show apparel, promotional apparel, and custom products with all-over printing. Polyester-coated or polymer-coated products such as mugs, metal plates, or cell phone cases can also be sublimated.
To achieve a clean result, several factors must align: the sublimation printer, sublimation inks, sublimation paper, design data, DPI resolution, pressing time, temperature, and material. If any of these factors are off, it can result in color deviations, blurred contours, or reduced durability. That’s why sublimation should always be planned with the intended application in mind.
What documentation is important for sublimation and corporate fashion?
When it comes to professional corporate fashion, it’s not enough to simply evaluate the print. The key factors are material quality, fit, availability for reordering, washability, sustainability, and actual use within the company. A durable garment that people enjoy wearing is often more sustainable in practice than inexpensive clothing that needs to be replaced quickly.
At textilekonzepte, we therefore focus on suitable materials, high-quality craftsmanship, and robust standards. For sustainable corporate apparel, certifications such as GOTS, GRS, and the GRÜNE KNOPF can provide important guidance. While they are no substitute for textile consulting, they do create greater transparency regarding materials, the supply chain, and product requirements.
Scientific testing is also helpful when it comes to making reliable claims. Studies on sublimation printing, for example, examine wash fastness, sweat fastness, light fastness, print quality, and the physical properties of printed fabrics.

Frequently Asked Questions About Textile Printing
Is sublimation printing durable?
Yes, sublimation printing can be very durable on suitable polyester fabrics. The ink bonds with the fiber rather than sitting on the surface as a film. It is important to use the right fabrics, high-quality ink, and the correct process parameters.
Is sublimation better than embroidery?
Not necessarily. Embroidery is ideal for logos and smaller designs. Sublimation is better suited for all-over prints, color gradients, photo designs, and very lightweight performance apparel.
Can you use the sublimation process on cotton?
Traditional sublimation is not suitable for cotton. It requires polyester fibers or a special coating.
Does an all-over print remain breathable?
With sublimation printing, no sealed film is applied. However, breathability still depends on the fabric and how it is manufactured.
Which products can be sublimated?
In addition to textiles, coated items such as mugs, cell phone cases, metal plates, and pillowcases can also be sublimated.
