In the dynamic world of textile printing, developments never stand still. Where choices were once limited to traditional screen printing or basic flex foil, today we embrace the latest technologies to provide our clients with the best results. The technique currently taking the market by storm and playing a central role in our production is DTF, or Direct to Film.
What exactly does this technique involve? How do we apply it, and what does it mean for the final quality of the apparel? In this article, we break down the technique in full.
What is DTF (Direct to Film)?
DTF refers to a process where a design is not printed directly onto the fabric, but first onto a special, transparent film. It is a technique that combines the durability of traditional ink with the flexibility of digital printing. This allows us to realize complex, multi-color designs on virtually any type of textile, without the limitations often associated with older techniques.
Our process: from digital file to textile
1. The printing process
Our high-quality printers print the design onto a film roll. First, the colors are applied, immediately followed by a layer of white ink. This white base is crucial, as it ensures that the colors remain bright and vibrant, even on dark garments.
2. Powdering
While the ink is still wet, the machine automatically applies a special adhesive powder to the back of the print. This granulate ensures proper bonding with the fabric.
3. Curing or drying
The film then passes through a drying tunnel. Here, the powder fuses with the ink to form a strong and flexible layer. This is the secret behind the final product’s excellent washability.
4. The transfer process
We accurately position the film onto the textile. Using a heat press, the design is pressed into the fibers of the fabric under specific pressure and temperature.
5. The finish
After pressing, the film is removed, leaving behind a razor-sharp print that has become one with the fabric.

The advantages and disadvantages
At LX Concept, transparency is our priority. Every printing technique has its own unique characteristics.
The advantages:
The greatest advantage is the level of detail. Unlike flex foil, DTF does not require weeding or picking. This means we can print even the smallest details and floating elements. Additionally, the colors really pop off the textile thanks to the white underlayer. The versatility is also immense: while some techniques struggle with polyester or nylon, the DTF method adheres perfectly to various materials such as sportswear and workwear.
The disadvantages:
With very large and solid areas, such as a fully filled circle on the back, the print may feel slightly less breathable than ink that absorbs directly into the fabric. We therefore often advise leaving open spaces in the design for optimal wearing comfort. Additionally, there is a thin layer on the fabric. However, this feels much more flexible and thinner than traditional transfers.
