Unique identifiers and variable data on the line

Serialization and other variable-data jobs require a coder that can change content from pack to pack without stopping the line. MARKTECH printers and laser markers support serial numbers, unique 2D codes, and related identifiers; the control system and data path are as important as the print technology itself.

Platforms used for unique codes

• The H200 Series prints text, date, serial number, shift, barcodes, and 2D codes. Variable data can be sent over Ethernet or RS232. The series is also used for UDI-style marks on cartons, films, and labels — a description of the mark type, not a claimed certification.
• Cx-series CIJ printers print date, time, logo, batch, class, and serial data, plus QR and DataMatrix codes, with Ethernet, RS485, and MODBUS-capable I/O for line handshake.
• The 4005 compact UV and the L-series flying lasers are options when a permanent unique mark is required on a compatible substrate.

What we can and cannot claim

MARKTECH supplies capable coding hardware and can work with your team on samples and available installation documentation for the selected configuration. We do not claim regulatory certification — including UDI or serialization scheme approval — on your behalf. Validation remains the responsibility of the producer and their quality team. For packaging context, see the pharmaceuticals industry page.

Planning the data path

Before installation, confirm how unique values will be generated or received, how the product-detect signal is wired, and how failed marks are handled. The integration checklist covers encoder, photocell, I/O, and MODBUS basics used on MARKTECH platforms.

Specification checklist

• Identifier format — serial number, unique 2D code, or UDI-style mark (a description of the mark type, not a claimed certification)
• Whether unique values are generated at the printer or sent from a host system
• The intended interface: H200 Series can receive variable data over Ethernet or RS232; Cx-series printers include Ethernet, RS485, and MODBUS-capable I/O
• Product-detect and reject handling, and the substrate plus required throughput
• Human-readable content that must sit with the unique code, such as batch or expiry — see date and lot coding
