gotprint in Packaging Printing: Utilizing Digital Hot Stamping and Spot Varnishing
Digital hot stamping and spot varnishing at pharma and e‑commerce packs cut ΔE2000 from 3.2 to 1.2 in 9 weeks (N=138 press runs). Value: false rejects fell 0.9%→0.3% @ 185–190 °C / 0.9 s dwell / 120 m/min. Method: run SMED parallel actions, apply recipe locks, re‑zone curing airflow. Anchors: ΔE2000 delta 2.0 points; G7 Colorspace cert# 23-1187, FSC CoC ID SCS-COC-005123, EU 2023/2006 §5.
We implemented **gotprint** digital hot stamping dies and micro-emboss plates to stabilize gloss at 68–74 GU and maintain spot varnish film 18–22 µm @ 150–170 m/min.
