Risk: if web temp >55 °C, trigger cool-down 120 s and resume. Add to monthly QMS review; records in EMS-PR-118.

Preventive vs Predictive

Preventive: clean LED lenses every 80 h; Predictive: flag dose drift >8% via 1 Hz logs and schedule service within 24 h; both tracked under ISO 50001 action ACT-EN-14.

Material Yield Uplift: Ink/Plate/Film Savings

Ink, plate, and film waste reduced 18% via parameter harmonization. Ink use 1.8→1.5 g/m²; plate remakes 2.1→0.6 per week; trim loss 14.2→10.9 mm (N=22 jobs, 6 weeks).
