Date, batch & expiry coding

Manufacturing and expiry dates, batch and lot numbers — printed on every pack by contact or non-contact coders, inline or by hand.

01 What it is

Date & batch coding, explained

Date and batch coding is the most common marking task on a packaging line. PACODE’s About page describes it directly: contact and non-contact coding systems “used for the printing of Manufacturing & Expiry dates, Batch Numbers and Price”.

The printer updates the code itself. On X1JET and Integra systems, date and time are available from the Basic configuration and counters and date offsets from Advanced, so an expiry date can be calculated from the production date automatically.

What can be printed

Date & time
Basic configuration and above (X1JET, PP 108); all Integra One configurations
Date offset
Advanced configuration and above — e.g. expiry calculated from production date
Counters
Advanced configuration and above
Text & logos
All configurations

Configuration names refer to PACODE’s published comparison tables.

06 How it works

Step by step

  1. 01

    Create the layout

    Layouts are designed on a PC — Markoprint iDesign for inkjet systems, PCset graphic for REINER handhelds — and transferred by USB stick, Ethernet or Bluetooth depending on the model.

  2. 02

    Trigger on the product

    An integrated or external photo sensor starts each print as the pack passes; a rotary encoder keeps the print in step with line speed. Hot ink roll coders print with the packing machine’s cycle.

  3. 03

    Print the code

    Inkjet printheads mark without touching the pack; hot ink roll coders press heated type, inked by a solid-ink roll, onto the film.

  4. 04

    Dates update themselves

    Date/time, counters and date offsets update automatically in the configurations that support them, so the code changes without stopping the line.

Questions

Frequently asked

Can the printer calculate the expiry date automatically?

Yes, in configurations with a date offset. PACODE’s comparison tables list date offset from the Advanced configuration of X1JET and Integra PP 108, and in the Print, Advanced and Pro configurations of Integra One.

What is the difference between contact and non-contact coding?

Contact coders — such as Dikai hot ink roll coders — press heated type onto the pack. Non-contact coders — thermal and piezo inkjet printers — spray ink without touching it. PACODE supplies both types.

Which materials can be date coded?

PACODE lists paper (coated or non-coated), PE/PP/PET materials, aluminium foil, wood and metal tin sheet. Individual models list their own surfaces on each product page.
