Galvanometer Scanning with 9.3 µm CO₂ Lasers for On-The-Fly Converting
Synchronized power, not scan speed alone, decides cut quality at 10 m/s.
Mechanical die-cutting locks roll-to-roll converting lines into one design per shift. Storing dozens of dies, changing them between SKUs, and the impossibility of short-run prototypes — these are the constraints that make digital printing’s flexibility hit a wall at the cutting step. Laser converting is the obvious answer, but only if it matches digital print’s design agility without sacrificing finish quality.
This technical paper demonstrates an all-digital galvanometer scan head paired with a 9.3 µm CO₂ laser — running at 10 m/s with focal spot under 150 µm — using coordinated power modulation across scan velocity for stable power density. The result: clean, repeatable cutting on thin plastic films, paper, cardboard, optical films, and apparel fabrics at digital-print speeds.
Key takeaways include:
- Why coordinated power modulation, not raw speed alone, determines cut quality at 10 m/s
- How 9.3 µm CO₂ wavelength produces cleaner cuts on common converting materials than 10.6 µm
- When digital converting beats die-cutting: short-run packaging, on-the-fly design changes, prototype production
- What system specs to look for: ≥10 m/s scan speed, <150 µm focal spot, frequency-stable 9.3 µm CO₂ source
- A practical materials list: flexible packaging, labels, greeting cards/envelopes, optical films, apparel fabrics
