How to Choose a Date Coding Machine: 7 Questions

Last Updated: 2026-09-05

The search phrase how to choose date coding machine usually hides a simpler question: which coder will not let me down on my actual line. The answer is rarely a brand. Seven questions, asked in order, will eliminate most wrong purchases before any money moves.

The Short Answer

Seven questions cover the decision:

One: what surface am I coding? Porous cartons, glossy film, glass, and metal each eliminate technologies. Two: how fast does the line run? Speed separates the inkjet families. Three: what data, and how often does it change? Daily date changes need a fast, foolproof controller. Four: how long must the code survive? Distribution-grade and life-of-product point to different methods. Five: what does it cost per thousand codes? Consumables decide the total. Six: who services it in my region? Seven: can I see it print on my product before paying?

A supplier who welcomes all seven questions is telling you something; so is one who deflects them.

What to Know in Practice

Price the second year, not the invoice. Ask for ink consumption at your code size and duty cycle, spares pricing, and the service channel to your region, then project across a full production cycle. Quote rankings often reverse once running costs enter the comparison.

Involve the operators early. A date coder that fights the people running it collects workarounds, and workarounds are where wrong dates and unreadable codes are born. If the interface and daily routine pass the operator test, you have verified something no specification sheet covers. Finally, agree the acceptance test in writing before you order: your substrate, your speed, your code, run for a full shift, and readability checked at the end of handling. A supplier who signs that test is one you can hold to it.

Related Questions

What is the most common date coding mistake?

Buying on machine price while ignoring consumable cost and support reach. The invoice is the smallest number in the lifetime of the deal.

CIJ, TIJ, or laser for date coding?

CIJ for fast lines and hard surfaces, TIJ for cartons at moderate speed, laser when the code must never fade. Let substrate and speed decide, then verify with samples.

How often should a date coder be serviced?

Daily checks take minutes and prevent most failures: fluid levels, a cleaning cycle, and a test code someone actually reads.
