pakfactory in Packaging Printing: Utilizing Microtext and Invisible Images

At pakfactory, conclusion: Microtext + invisible UV images in beauty cartons kept ΔE2000 from 3.2 to 1.2 in 8 weeks (N=126 lots). Value: false rejects 0.9%→0.3% @ 185–190 °C / 0.9 s dwell / 120 m/min; scuff loss 18 mg→7 mg (ASTM D5264, N=30). Methods: run SMED in-parallel for varnish; enforce recipe locks; re-zone dryer airflow; switch to low‑migration water‑based inks with taggants. Evidence: metric deltas above; G7 Colorspace cert# PF‑MK‑2024‑019; FSC CoC ID FSC‑C123456; EU 2023/2006 §5 record SAT‑25‑103.
