Summa S Class 3 T Series Precision Cutting for High-Volume DTF Production
Summa S Class 3 T Series Precision Cutting for High-Volume DTF Production
Couldn't load pickup availability
The Summa S Class 3 T Series combines industry-leading precision with the power of True Tangential Cutting Technology, making it one of the most advanced roll-fed cutters available for DTF production. Designed for accuracy, speed, and long-term reliability, it delivers the cutting performance needed for today's high-volume print shops
True Tangential Cutting Technology
At the heart of the S Class 3 T Series is Summa's motorized True Tangential cutting head, which electronically controls blade rotation to ensure the blade is always positioned at the optimal cutting angle. With up to 1,000 grams of cutting force, the cutter produces exceptionally clean corners, sharp detail, and consistent results—even on intricate graphics, small lettering, and challenging materials like DTF PET film.
Unlike traditional drag-knife cutters, the True Tangential system maintains superior accuracy throughout every cut, reducing errors and delivering professional-quality transfers every time.
OptiCut Technology for Maximum Accuracy
The S Class 3 T Series also features OptiCut Technology, an intelligent cutting algorithm that continually compensates for blade wear and offset changes. By automatically adjusting blade positioning throughout the cutting process, OptiCut maintains exceptional accuracy and consistent cut quality while extending blade life and reducing the need for manual adjustments.
The result is smoother cuts, greater reliability, and less downtime during production.
FlexCut Perforation Cutting for DTF Transfers
One of the most valuable features for DTF production is Summa FlexCut®.
While FlexCut can perform complete through-cuts when needed, DTF Tech Gurus recommends configuring it for perforation cutting. This allows each transfer to remain attached to the roll while still separating easily by hand when it's time to heat press.
Unlike flatbed cutters that leave individual transfers scattered across a table or floor, the Summa S Class 3 T keeps every transfer organized on the roll. Entire print jobs stay together from printing through finishing, reducing handling time, minimizing the risk of mixed-up orders, and creating a much more efficient production workflow.
When paired with Wasatch SoftRIP, registration marks, cut paths, and QR-coded job information are generated automatically, creating a streamlined print-and-cut workflow that helps maximize productivity while delivering precise, repeatable results.
Whether you're producing dozens or thousands of transfers each day, the Summa S Class 3 T Series provides the speed, precision, and workflow automation needed to build a truly professional DTF production environment.

Summa S Class 3 T Series: Tangential Cutting
Summa’s True Tangential cutting technology delivers ultimate cutting precision and performance. The motorised knife is ideal for cutting DTF transfers, and does it with ease. Unlike other upright cutters, the knife pivots, preventing the snagging of the film.
Tangential Cutting Head | S Class 3 T(C) Series
Featuring computer-controlled blade rotation and up to 1000 grams of cutting force, Summa’s T Series combines the precision of a flatbed cutter with the ease and speed of a roll-fed cutter by using our legendary True Tangential cutting head. The T Series cuts with more force and accuracy than any other cutter in its class.
To prevent damage during the cutting process, it's essential to minimize friction by avoiding contact between the media and the roll. That’s where our Frictionless Roll Feed comes in. When the roll is wound with the ink facing outward, the feeding system ensures smooth and uninterrupted feeding, effectively eliminating this concern.
The S One Series offers you leading-edge cutting technology without
compromise. Up-to-date techniques deliver the highest contour-cutting
accuracy for printed graphics. This makes the S One roll cutter a
flexible and future-proof unit.
The S One Series is the next step in growing your business and is designed with a focus on ergonomics and simplicity in usage. An extremely fast OPOS sensor system compensates for any deformation
of the print and increases the speed by which registration marks are read. The sophisticated OPOS Xtra feature allows to process most intricate jobs with the highest accuracy.
The S Class 3 T models feature an advanced cutting head designed to streamline production and improve accuracy. By processing data directly within the cutter—rather than relying on external software—registration mark detection is significantly faster and more precise.
When paired with Wasatch SoftRIP, cut marks are generated during the ripping process, seamlessly aligning with your print files. Once cut paths are established, all job data is encoded into a QR code, allowing the cutter to automatically recognize and execute the correct cuts for each job without additional setup.
This workflow not only saves substantial production time but also ensures consistent, high-precision results on every run. For high-volume operations, the system can be configured with template-based layouts—ideal for nested images and fully automated environments, including integration with robotic arms and rotary heat presses to maximize throughput and efficiency.
To efficiently handle DTF / PET film, which remains in roll format after cutting, Summa developed a custom roll-up system for the S3 T units.
After finishing a job, the system will roll up the artwork neatly and prepare the machine for the next one. The integrated paneling feature splits long runs into shorter consecutive tasks, allowing for cutting complete rolls unattended and deliver the output nicely rolled up.

Frequently Asked Questions
Spec Sheet Download
Can I install this myself? Yes - here are the instructions / video
Yes you can ! This comes on a smaller pallet and there are instructions in this PDF Attachment and here is the video
What Rip Software does it require
Wasatch SoftRIP has included the Summa S3 T Series Cutter to match the X5 DTF System. You can operate the cutter as a roll feed, or you can even install direct off the printer. (get with DTF Tech Gurus for instruction on set up for that configuration)
What is a tangential cutting head.
Tangential Movement
1. The tangential knife stops cutting right before a corner.
2. A motor lifts and reorients the blade.
3. Once the blade has reached the desired angle, it is lowered and continues to cut the corner.
