01
Front label hierarchy
Variable data and traceability packaging need more than a QR code on the back panel. They require data ownership, artwork rules, proofing discipline, scan testing, and a clear decision about what changes by SKU, batch, market, or campaign.
02

Material and finish callout
Turns traceability into a production-ready brief.

Back panel, barcode, lot/date
Back-panel and variable-data zones are fixed before proof so quote review, artwork approval, and reorder files stay aligned.
