Overview
Industrial date coders print production dates, expiry dates, batch numbers, barcodes and variable data directly on packets and packaging. They are mounted on packaging lines to provide continuous, automated marking adapted to production speed and package format.

Types

• Thermal embossing ribbon coder: economical, mechanical solution that imprints numbers and letters using a ribbon; limited to 2–3 rows and typically up to 10 characters per row; suitable for simple, low-variability applications and easy onsite repair.
• Digital thermal inkjet printer: touchscreen-programmable system allowing rapid content changes without mechanical adjustments; supports variable text, barcodes and small logos; fast cartridge replacement and flexible formatting for medium to high variability production. Common suppliers: Videojet, Domino, Markem Imaje.
• Laser printing equipment: non-consumable marking solution with low running cost and very high printing speed; suitable for large-volume operations where no inks or cartridges are desired.

Description
The date coder is an inline marking device integrated on packaging machines to apply dates, batch codes, barcodes and other identifiers. Selection of coder technology depends on required print content, line speed, substrate and maintenance constraints. Systems can be interfaced with production controls for synchronized variable data printing.

Applications
Used on packets, pouches, cartons and other packaging in food, pharmaceutical, chemical and industrial sectors to mark production/expiry dates, lot codes, barcodes and small logos. Applicable to low-, medium- and high-speed lines according to the technology chosen.

Technical characteristics / specifications

• Thermal embossing ribbon coder: numeric and alphanumeric printing only; max 2–3 rows; typically ≤10 characters/row; low capital cost; limited flexibility for frequent changes.
• Digital thermal inkjet printer: touchscreen programming; supports variable text, barcodes and small graphics; quick cartridge replacement; adaptable print heights and formats.
• Laser printer: no consumables (very low running cost); high-speed capability for large productions; higher initial investment.
• Integration: designed for mounting on packaging machines, matched to line speed, trigger signals and package formats.
• Print capabilities: production/expiry dates, batch numbers, barcodes, small logos and serialized data.
