SUMMA S3 VINYL CUTTERS FOR THE CUTTING OF DTF PRINTS

In recent years, DTF printing has emerged as one of the most innovative and transformative technologies in the textile and apparel industry. DTF printing has a projected worth of up to €3.44 billion by 2030. Its success has been propelled by a growing demand for customisation and a streamlined production process. DTF offers a cost-effective and high-quality alternative to traditional printing methods, such as screen-printing and sublimation. Thanks to its ability to deliver vibrant, durable prints on a wide range of fabrics, this technology has become a favourite of businesses of all sizes. 

As DTF technology evolves, it is reshaping production workflows and unlocking new creative possibilities for textile decoration. However, cutting the printed DTF designs efficiently and without any blemishes remains a challenge. Specialised solutions, such as Summa’s S3 TC vinyl cutters, are becoming essential for high-volume, professional production.

DTF printing is a multi-step process that begins with digital artwork. The artwork is printed onto a specialised polyethylene terephthalate (PET) film using a modified inkjet printer with pigment-based DTF inks. The printer starts by laying down a full-colour layer, followed by a white ink backing that ensures opacity and vibrancy across all fabric types. While the ink is still wet, a hot-melt adhesive powder is applied to the film. This powder acts as a bonding agent, allowing the design to securely adhere to the fabric when heat is applied.

The printed film is then cured using a curing oven, which melts the adhesive powder and prepares the transfer for application. Finally, the design is cut out from the film and placed onto the garment. Heat and pressure are then applied to bond the design to the fabric. Once cooled, the PET film is peeled away, leaving a vivid, long-lasting print behind.

What sets DTF apart is its incredible versatility. Unlike sublimation – which works only on polyester-based materials – DTF can be used on a wide range of textiles. These include cotton, polyester, blends, nylon and leather. The resulting prints are exceptionally durable, resistant to washing and stretching, and capable of capturing fine details and vibrant colours. 

The benefits of DTF technology are clear. It offers unmatched flexibility across fabric types, durability that rivals traditional screen printing and a simplified workflow, accessible to small businesses and start-ups. It is also cost-effective for short runs, making it a popular choice for niche brands, personalised apparel and on-demand, e-commerce production.

However, there are also some challenges to keep in mind. The initial investment in high-quality DTF equipment can be significant and proper training is essential to operate it effectively. Additionally, regular maintenance – particularly for the white ink – is crucial to ensure consistent performance and longevity.

One of the most pressing operational challenges poses itself in the cutting stage. After printing, DTF transfers are produced on rolls of PET film that must be cut into individual designs or sheets before heat pressing. Not only can this stage become a major bottleneck, which slows down production, but also most vinyl cutters are not optimised to cut sensitive PET film. This results in scratches that impact the quality of the final product. 

These challenges highlight the need for specialised cutting equipment designed specifically to handle the unique properties of DTF film while also protecting delicate, freshly printed designs.

“What sets DTF apart is its incredible versatility”

Recognising these challenges, Summa has developed dedicated DTF roll-feed systems for its SE TC vinyl cutters. They are engineered to deliver precise, efficient and frictionless cutting, ensuring that every transfer is handled with care and accuracy. 

At the core of this solution is Summa’s TC cutting head, which features tangential cutting technology. The technology is fast and incredibly precise, easily fixing the bottleneck problem.

To protect the inked side of the film, DTF rolls are positioned with the ink facing the cutting knife. This ensures that there is no direct contact with the machine and eliminates friction which, in turn, reduces the risk of scratching. Because the film is translucent and requires white registration marks for alignment, the cutting head also includes an integrated camera. The camera offers the highest level of accuracy for detecting these marks and delivering perfectly aligned cuts.

The vinyl cutter comes with a frictionless roll-feed system that further enhances print protection. The system prevents the inked surface from rubbing against any part of the machine during feeding, again reducing the chances of scratching. It also keeps the PET film stable and flat, eliminating concerns about curling or shifting during long production runs.

Once the designs are cut, a custom roll-up system rewinds the film into a neatly organised roll. This makes it easier to handle and ideal for roll-to-roll workflows. When combined with Summa’s automatic barcode functionality, the system enables unattended, overnight cutting for continuous production.

In addition to Summa’s S3 TC75 DTF edition, the company now also provides a specialised DTF version of its larger S3 TC160 model. This expanded option is perfect for businesses managing wider rolls or high-volume production. The S3 TC160 delivers the same precision, efficiency and media protection as the TC75, while providing a broader cutting capacity. This makes it ideal for bulk rolls, oversized designs and expanding product offerings.

Consumer demand for personalised and on-demand products continues to rise, as predicted. As a result, DTF printing is positioned to become a dominant force in garment decoration. Advancements in automated powdering systems, eco-friendly materials and faster printers are making the process even more sustainable and efficient. When paired with innovations, such as Summa’s specialised cutters, the entire workflow – from printing to cutting to transfer – becomes seamless and highly scalable.

This combination of cutting-edge printing and precision-cutting technology is driving the next wave of growth in the digital-textile industry. These combined processes are bridging the gap between small-scale creators and high-volume manufacturers.

DTF printing has revolutionised textile decoration. However, its full potential can only be realised when every stage of production is optimised, including the critical cutting phase. Summa has developed dedicated DTF roll-feed systems for its S3 TC vinyl cutters that addresses the unique challenges of DTF film handling.

Businesses are becoming eager to meet the growing demand for custom-printed apparel. The combination of DTF printing and Summa’s specialised cutting systems represents a complete, future-ready workflow that drives growth, profitability and customer satisfaction.
