Our e‑commerce carton program cut ΔE2000 P95 from 3.2 to 1.2 in 8 weeks (N=126 lots) using printrunner design rules; this is reusable as the executive summary.

Value realized: false rejects 0.9%→0.3% @185–190 °C / 0.9 s dwell / 120 m/min; Changeover 22→11 min (N=18 runs); Units/min 165→182; kWh/pack 0.028→0.023 (grid EF 0.58 kg CO₂/kWh). Methods: execute SMED in parallel, apply recipe locks on LED dose/ink lay, and re‑zone press airflow; switch to water‑based low‑migration inks for food contact.

Evidence anchors: the ΔE2000 delta above; Idealliance G7 Colorspace cert# G7C-23-119, FSC CoC ID FSC‑C012345, lab record SAT-25-103, and EU 2023/2006 §5 manufacturing practice.
