Sigma Series
High-Speed Semi-Rotary Digital Label Finishing System
The Sigma Series is a modular digital label finishing system designed to support high-mix, fast-turnaround label production environments. Built for flexibility and control, it enables efficient finishing of digitally printed labels while maintaining accurate registration and consistent output across both short-run and longer production workflows.
With support for both full-rotary and semi-rotary operation, the Sigma Series provides a practical platform for converters looking to scale digital finishing capabilities without compromising quality or efficiency.
Where the Sigma Series Fits Best
Optimized for label converting operations that face high-pressure deadlines and frequent job changes.
Frequent Changeovers
Minimize downtime between short runs with tool-less setup and intuitive controls.
Multi-SKU Workflows
Manage complex job batches with ease using programmable recipe storage.
Precise Registration
Maintain tight tolerances on sophisticated designs with servo-driven alignment.
Scalable Platform
Protect your investment with an architecture that grows with your business.
Key Capabilities - Engineered for Versatility and Scale
Full-Rotary & Semi-Rotary Operation
Switch between modes to maximize efficiency. Use full-rotary for high-speed, long-run throughput, or semi-rotary to reduce tooling costs and setup time for short-run digital jobs.
Servo-Driven Re-Registration
An integrated servo system ensures pinpoint alignment between printed images and die cutting, supporting consistent quality across a wide range of substrates.
High-Speed, Continuous Production
Engineered for robust roll-to-roll operation, the Sigma Series maintains tension control and registration consistency even at high production speeds.
Modular Finishing Platform
The system’s architecture allows you to add functionality as your needs change, protecting your initial investment and preventing equipment obsolescence.
