Coding and Marking Systems: Which Solution is Right for Your Business?

By Grainne Carroll

Coding and marking are essential to ensure traceability, accurate identification and regulatory compliance across a wide range of industries. Whether it’s barcodes, batch details or expiry date applications, an efficient system will enhance the security and productivity of your supply chain.

In this blog, we’ll explore the benefits of a quality coding and marking solution and take a closer look at the most commonly used technologies today.

Why a Good Coding & Marking System Matters

A quality system supports better inventory management. Clear and durable printing reduces supply chain errors and ensures accurate product identification throughout the logistics process.
A quality printing system will minimise print errors. This in turn will reduce waste material, downtime, and improve overall production efficiency.
A high-speed marking or labelling system that integrates effectively into a production line, maintains production efficiencies and keeps operations running smoothly.
Quality printing of barcodes, batch numbers and expiration dates is essential for compliance with industry regulations. For companies operating in sectors such as Food and Pharma, regulations on coding on containers and secondary packaging is even more stringent, and a quality marking system is essential.

Coding and Marking Technologies

Choosing the right marking system for your operation depends on a number of factors, including your product, packaging, production speed and industry regulations. Let’s examine some of the more popular options available.

Inkjet Marking

Inkjet marking is widely used due to its versatility, speed and precision. This system offers the advantage of direct printing, without contact with the surface, which reduces equipment wear and avoids damage to the packaging. Inkjet printing is suitable for both porous and non-porous surfaces, ensuring a quality print across a variety of packaging such as boxes, trays and sacks.

Laser Marking

Becoming more popular in recent years particularly in the electronics and automotives industries, a laser creates a high-quality marking with the advantage of being wear resistant. However, adjustments can be costly, if either the packaging material or coding needs to be altered.

Thermal Transfer

Using an ink ribbon to transfer the markings by heat to the material surface, this method is ideal for printing on labels or flexible packaging. It achieves a durable quality finish with high resolution. As it uses consumables (ink ribbon) the cost of this method can mount up over time. In addition, its application is more limited to flexible materials, which restricts its use on certain types of packaging.

Industrial Labeling

Industrial labelling is an effective solution for product and packaging identification, particularly when real time variable data is needed. These systems support automatic printing of labels with barcodes, logistical information and other relevant data, ensuring accurate and GS1-compliant labeling.
