Quick Answers
What are Summa S-Series roll cutters?
S-Series roll cutters are professional vinyl cutting plotters built for accurate contour cutting (cutting around printed graphics following the image shape). They handle vinyl lettering, stickers, labels, vehicle wraps, and heat transfer materials. Summa's OPOS optical positioning system (camera-based print-to-cut alignment) automatically aligns cut paths to printed graphics, which is essential for print-and-cut workflows.
What's the difference between S One and S Class 3?
Summa S One cutters use drag knife technology with up to 600g cutting force. Ideal for growing businesses that need reliable, professional-grade cutting at a competitive price point. S Class 3 cutters offer your choice of drag knife, True Tangential, or dual-head (TC) configurations with up to 1000g force, faster speeds, longer tracking, and advanced features like OPOS CAM (wide-angle camera that reads all marks in one pass) and G-Performance mode (speed optimization boosting throughput up to 40%). Built for professionals who need maximum precision and throughput.
What materials can S-Series cutters handle?
S-Series cutters process adhesive vinyl, reflective vinyl, heat transfer (flex/flock), laminated prints, window films, sandblast stencil material (thick rubber masking for glass etching), and high-performance films. S Class 3 tangential models handle thicker and tougher materials, up to 0.047" for sandblast stencil, with greater precision on corners and fine details. Our team can help you select the right blade angles and cutting parameters for your specific materials.
What's the difference between drag knife and tangential cutting?
Drag knives are pulled through the material. Efficient for most vinyl and film applications. Tangential knives use a motorized blade that lifts and rotates at corners, delivering cleaner cuts on thick materials and sharper precision on intricate details. Summa's True Tangential technology is unique in the industry and available exclusively on S Class 3 T and TC models.
What widths are available?
S One models range from 24" (desktop) to 64" cutting width. S Class 3 models range from 30" to 64". Both lines include options for standard print widths and large-format applications.
