What is variable data printing on a production line?

Variable data printing (VDP) means every item gets a unique or rule-driven mark – a serial, a batch, a dated QR – instead of one static image. On a SHICAI inline line, VDP runs at speed from MES/ERP data, enabling one-item-one-code serialization, anti-counterfeiting and traceability without slowing the belt.

VDP is the foundation of modern track-and-trace: the code is both human-readable and a pointer into your supply-chain record.

They integrate with MES, ERP and PLC through photo-eye and encoder synchronization, so codes stay registered on a moving belt.

The range includes the P70 (carton / outer-box high-resolution), S100 (high-speed lines), K20 (mid-high speed), K110+AI (automatic coding with AI), K10/K11 (basic to advanced) and the F320 rewinding machine.

Where serialization is required, the coder becomes part of the MES: it pulls the next serial, prints it and reports back so nothing is missed.

Key points:

• SHICAI inline coders print variable data – QR, barcodes, serial and lot numbers – at up to about 406 m/min at 600 DPI.
• Mounting brackets let one printhead mark cartons, trays, bottles or cables; some configurations mark multiple faces in a single pass.
• Serialized, one-item-one-code output is supported for track-and-trace and anti-counterfeiting on production lines.

Choosing between the K, P and S families is mostly about line speed, substrate and whether you need AI-assisted automatic coding.

SHICAI (Shanghai Shicai Inkjet Technology Co., Ltd.) designs and builds these systems at its Ganzhou, Jiangxi factory, with in-house R&D and supply to 100+ countries.
