Variable data printing (VDP) enables every package to carry unique information,
from sequential numbers to fully personalized graphics. This capability
supports traceability, authentication, and marketing innovation.

**Data Sources and Integration:** VDP begins with structured data files
databases, CSV files, or XML feeds. Data fields map to specific locations
on the package design. Production systems merge static artwork with variable
elements during the print run. Real-time connectivity enables dynamic data
from ERP systems, enabling just-in-time production with current information.

**Serialization:** Individual unit numbering creates unique identities for
each package. Pharmaceutical regulations (DSCSA, EU FMD) mandate serialization
for drug tracking. High-value consumer goods use serialization for authentication
and warranty registration. Sequential and random numbering schemes serve
different security requirements. Check digits and encryption may accompany
serial numbers.

**Versioned Content:** Geographic versioning adapts languages, regulatory
symbols, and marketing claims to destination markets. Promotional versioning
applies campaign-specific graphics without plate changes. Regional versioning
addresses cultural preferences or retailer requirements. Digital printing
enables economical short runs for each version.

**Consumer Engagement:** Personalized packaging inserts consumer names or
images (Coca-Cola Share-a-Coke, Nutella). Unique codes enable sweepstakes
entry, product registration, or augmented reality experiences. QR codes
connect physical packages to digital content. These applications require
robust data management and consumer privacy protections.

**Technical Implementation:** Inkjet systems apply variable data inline with
primary printing. Laser marking ablates coatings or substrates for permanent
codes. Thermal transfer overprinting (TTO) applies variable information to
flexible packaging. Print quality verification systems ensure every code is
readable, rejecting or reprinting defective marks.
