High-speed printing of massive variable data — text, numbers, barcodes, QR codes, and serial / sequential numbers change on demand, variable from a single piece, accurate batch after batch.

Barcode · QR code · sequential numbering
Support for Code128, EAN, QR Code, Data Matrix (DM) and other symbologies, plus continuous / skipping sequential numbering schemes for retail, logistics, anti-counterfeit and traceability scenarios.

Multiple error-proofing mechanisms
Closed-loop verification between data generation and printing automatically checks against preset rules, eliminating skipped, missing, duplicated or wrong numbers to ensure every hang tag has a unique identity.
-
Integrated inspection system
Post-press integration with the DaHeng machine-vision inspection system verifies variable-data readability (barcode grade ≥ C), automatically rejecting defects so only qualified codes ship.
