sheet labels in Packaging Design: Utilizing Modular and Reconfigurable Design
We reduced ΔE2000 from 3.2 to 1.2 on regulated label runs in 8 weeks (N=126 lots), enabled by modular **sheet labels** layouts, SMED parallel tasks, recipe locks, and airflow re-zone.

Teams often ask do fedex labels expire; carriers vary, but our overprint date rules force ship-by checks within 10–14 days and prevent stale routing on reconfigurable layouts. By modularizing overprint zones and AI-to-proof gates, we sustain tighter ΔE control, faster changeovers, and traceable governance for regulated markets using **sheet labels**.
