Flex printing is a proven printing method for applying logos, lettering, or simple designs to textiles with clarity, opacity, and high quality. A clean print plays a particularly important role in corporate fashion, workwear, trade show apparel, and promotional apparel, as it directly contributes to your brand’s public image.
In flex printing, a flex film is cut using a cutting plotter, weeded, and then pressed onto the fabric using a heat press. The result is a smooth, often slightly glossy print with high opacity.
This process is particularly well-suited for clean designs, names, numbers, departments, slogans, and logos without subtle color gradients. Flexographic printing is an attractive option for businesses that need to print small to medium quantities reliably, cost-effectively, and professionally.

Flex printing or flock printing: Which is better for your design?
There is no one-size-fits-all answer to this question. The key factors are the design, the fabric, the intended use, the desired texture, and the level of detail. Screen printing produces a smooth, precise, and modern finish. Flock printing, on the other hand, has a velvety, slightly raised surface and a softer, more textile-like feel.
From our experience, we’re very familiar with this trade-off. One customer always insists on two-color flock printing, even for the very fine text in his slogan beneath the logo. That’s exactly what makes it a real challenge. Small letters, narrow lines, and two-color elements are significantly more difficult to weed and position precisely in flock printing.
In such cases, flex printing is often the better solution. It reproduces fine contours more accurately and produces a smoother, more professional print result.
How does flex transfer printing work on textiles?
In this transfer printing process, production begins with a suitable print file. A vector graphic is ideal because it allows for clean lines and precisely scalable contours. The design is cut from a flex film in a mirror-reversed orientation. Afterward, all excess film is removed. This step is called weeding.
The transfer film is then positioned on the fabric and bonded using a heat press under heat, pressure, and a specified pressing time. Cotton, polyester, blended fabrics, viscose, and nylon react differently to heat, pressure, and film adhesion. Therefore, you should check in advance whether the fabric, film, and design are technically compatible.
Textilekonzepte also describes its consulting services as being tailored to both the design and the fabric: Before the finishing process begins, the company determines which finishing method is best suited for the design and the fabric.
Durability: When Flex Print Remains Long-Lasting and Wash-Resistant
In flex transfer printing, durability is achieved through the proper coordination of the fabric, flex film, and processing. The key factors are film quality, temperature, contact pressure, and press time. If these steps are carried out correctly, the print will remain intact even with regular use.
This durability is particularly important for workwear. Shirts, polo shirts, hoodies, sweatshirts, and jackets are worn frequently, washed often, and subjected to heavy wear and tear during the workday. A logo or lettering must therefore not only look good when delivered, but also remain presentable even after many washes.
To ensure a long lifespan, printed textiles should be washed inside out and not ironed directly over the print. For highly elastic sportswear, coated polyester, or heat-sensitive blended fabrics, we always check in advance which flex film is suitable.
A Comparison of Various Textile Printing Methods
Not every printing method is suitable for every design. A simple logo has different requirements than a photo, a color gradient, or a large-scale back print. Therefore, the choice of printing method should be based not only on price, but also on the design, the fabric, the quantity, and the intended use.
| Printing Methods | Suitable for | Effect | Special Feature |
|---|---|---|---|
| Flex Printing | Logos, names, numbers, clear lettering | smooth, opaque, often slightly glossy | Precise for simple designs |
| Flock printing | Simple designs, large lettering | velvety, soft, slightly raised | more challenging with fine details |
| DTF Printing | multicolored designs, gradients, detailed logos | Vibrant colors, versatile applications | works well for more complex designs |
| Screen printing | Larger print runs | Vibrant colors, durable | cost-effective for large quantities |
| Embroidery | Polo shirts, shirts, jackets, caps | High-quality, three-dimensional | particularly elegant |

When DTF Printing Is a Better Alternative to Flex Printing
DTF printing is particularly well-suited for designs that are multicolored, rich in detail, or feature color gradients. While flex transfer excels at producing clean shapes, logos, and lettering, DTF printing can reproduce more complex designs with subtle gradations and vibrant colors.
This is relevant for companies whose corporate design consists not only of a simple word mark but also includes shading, small details, or multiple colors. DTF printing can be a practical solution even for smaller quantities because it does not require a traditional screen printing setup.
Flex printing remains the right choice when a design is simple, highly opaque, and clearly defined. DTF printing, on the other hand, is usually more suitable when color vibrancy, fine detail, and more complex logos are the priority. The decision should therefore always be based on the specific design.
Certifications, Standards, and Material Selection in Textile Printing
Corporate fashion isn’t just about the print. What matters just as much is the type of fabric being printed on and how responsibly the materials, production, and finishing processes are selected.
The durability of the print—and, of course, of the garment as a whole—is also crucial. In this regard, it’s important to consider how efficiently materials are actually used. In our flex and flock transfer processes, we make full use of all films, as we pass on weeded film scraps for upcycling. There, cutting scraps are transformed into entirely new products—which have been honored with the Green Product Award.

Frequently Asked Questions About Flex Printing, Flock Printing, and DTF Printing
Is flex printing better than flock printing?
Flex printing is better when you want fine lettering, sharp edges, and a smooth surface. Flock printing is better suited for simple, larger designs with a velvety feel.
When is DTF printing better than flex printing?
DTF printing is generally better for designs that are multicolored, rich in detail, or feature color gradients. Flex printing is better suited for clear logos, names, and lettering.
Is flex printing suitable for workwear?
Yes, as long as the fabric, film, and care requirements are compatible. Logos, names, department names, and functional labels, in particular, can be applied very well.
Can flex printing be multicolor?
Yes, multicolor flexographic printing is possible. When using multiple colors, weeding, positioning, and registration must be carefully checked.
How durable is flex printing?
Durability depends on the quality of the film, the fabric, the workmanship, and how it is cared for. When applied properly, flex printing is wash-resistant and suitable for everyday use.
