Finding the correct batch coding machine for your company is a massive decision. Choosing between all of the different types of batch coding machines that Domino Amjet offers, there's a big difference between the technologies and finding the perfect one for your line can be a daunting decision. 

But, never fear, because the experts at Domino Amjet are here to help. In this blog, you'll discover the most efficient and cost-effective solutions for the unique needs of your company.

Choosing the perfect batch coding machine is an absolute necessity because the needs of each and every company is so specific. Even two companies within the same industry can be vastly different, depending on size, number lines, specific subset of the industry, etc. That's why it's absolutely imperative to ensure that products can move seamlessly throughout a supply chain. But with so many batch coding options available, it can be difficult to know which machine is best.

Which Factors Should You Consider? 

Different industries require batch coding machines capable of applying codes and data to a wide variety of products and packaging. Consider the type of substrate and product and have that in-mind when considering a coder. There are several other variables to consider as well, including production line speeds, factory environment and other considerations. These will all come into play when you're looking at a new coder or printer for your line. 

In this post we will take you through details of all the different technologies on offer, and how these apply to different industries and products so that you can make a truly informed choice when choosing the batch coding machine for your business.

What is batch coding?

Batch coding is the process of adding an identifying code, typically made up of a selection of letters and numbers, to a set of identical products that share the same production time, date, and location. Batch coding is critical for traceability, enabling a single item to be traced through all stages of production, processing, and distribution.

The importance of batch coding

Whether you work in industrial and manufacturing applications, food and drink production, or the pharmaceutical or automotive industries, batch coding will feature as an integral part of your manufacturing process.

Batch codes are critical for traceability, enabling a product to be traced through all stages of production, processing, and distribution. Individual batch numbers are made up of a combination of different identifying codes, relating to the product, production line, production date, the time of production, and so on.

When a customer buys two identical items from a supermarket, they may have exactly the same ingredients, in exactly the same quantities, but if they were made on a different day, or on a different production line, or with ingredients sourced from a different supplier, they will still have different batch codes.

As the product base has diversified across several industries, proper coding has become even more important. More products means more codes and more codes means a better chance to limit the damage if there's a recall.

Batch Codes are vitally important for product recalls. If a consumer, retailer, or anyone further down the supply chain finds a problem with a product, the batch code allows the product to be traced back to the source to a limited batch of product for the recall as opposed to a massive general recall, vastly limiting costs.

Products with the same batch code can then be withdrawn from sale at a reduced cost to the manufacturer. After all, the larger a product’s batch, the more costly it is to facilitate a product recall.

Types of batch coding machine

Manual batch coding solutions

Manual batch coding machines are operated by hand and generally only suitable for very small production runs. Examples of these machines include traditional hot stamps, and ink pad, or sticker roller coding machines. This type of machine will typically be used by small manufacturers, producing a small range of products, often by hand and for limited distribution.

Semi-automatic batch coding solutions

Semi-automatic batch coding solutions are electronically driven, and apply codes automatically, but do not integrate onto automatic supply lines, meaning that product feeding and collection must be done by hand.

Automatic batch coding solutions

Automatic batch coding machines apply data to products as they run along a production line without the need for any operator intervention. Once an automatic batch coder is set up with the required code, product feeding and printing are carried out automatically until a change in product or code is required. Automatic batch coding solutions are the preferred choice for large scale production or automated production lines.

Contact or non-contact?

All batch coding machines, whether manual, semi-automatic, or automatic are further divided into two main categories – contact and non-contact. Whether you require a contact or non-contact batch coder will depend on your industry, and the type of product being produced.

Contact batch coding machines

Contact batch coding machines come into direct contact with the surface of the product or packaging being coded. Contact batch coding solutions include traditional rubber or metal stamps, as well as automatic thermal transfer overprinting (TTO) machines.  

Non-contact batch coding machines

Non-contact batch coding machines do not physically meet the surface of the product being coded, and instead use techniques such as lasers and ink sprays to apply the desired code. Non-contact machines are good for batch codes which need to be changed frequently. Examples of non-contact batch coding solutions include continuous inkjet (CIJ) and thermal Inkjet (TIJ) printers, and laser coders.


Thermal transfer overprinting

Domino’s V-Series range of thermal transfer overprinters can be used at high speeds to produce high-quality codes on flexible films and labels. TTO printing is a preferred technology for batch coding processed and convenience food, with printers integrated into packaging and processing equipment including tray sealers, flow wrappers, and baggers.

In a TTO solution, a code is transferred directly onto a product packaging or label, using heat applied to an ink ribbon in a specified target area, as such the print head must come into full contact with the print area in order to produce a code.

Continuous inkjet printing

For some applications, a non-ink-based batch coder may present the best solution. For example, in the beverage sector, printing batch codes on the bottom of beer cans, wine bottles, and water bottles will require a system capable of printing on foil seals, PET, and glass, such as a scribing laser.

Such a solution can be found in Domino Printing’s range of durable D-Series CO2 lasers and F-Series fiber lasers – high-speed, harsh environment laser marking machines capable of coding onto a wide range of items and materials. This includes glass, plastic, foil, and metal.

Options for handling batch code information

Another important consideration when choosing a batch coding machine is how you would like to handle your data. There are various options available from manual data entry, through to full coding automation.

Manual data control

At entry-level, data can be entered directly onto a batch coding machine for printing onto a product or packaging. In such a scenario, an operative would be employed to enter all data onto a label design or code template. The machine would then print the code onto the product. Such a system can be susceptible to coding errors if an operative makes a mistake during data entry, which can necessitate product recalls.

Semi-automated control                                                                           

Another option for manufacturers is semi-automated data control, where a batch coder can automatically populate a label or code template based on certain information. In such a scenario, an operative would be required to enter data from defined categories, for example, date, product code, line number, etc., into a piece of software that would then translate the data into final code for printing. Domino’s QuickStep user interface is provided with all Domino batch coding machines, enabling operatives to design labels and code structure, and automatically populate designs based on manually entered information.

Fully-automated data control

A more advanced solution for manufacturers comes in the form of a batch coding software that can integrate into an existing supply system to create batch numbers based on product data and automatically populate the label software. Domino’s QuickDesign coding automation and label design software enables all Domino printers to integrate into MES and ERP systems, to accurately collect and curate data and automatically switch messages. A coding automation system eliminates the need for human touch, resulting in fewer errors, less downtime, and greater operator capacity to carry out tasks elsewhere on the factory floor.
