Consulting and Products
If you want to print expiration dates, automatically apply best-before dates, or integrate date coding into your existing production processes, you should look for more than just a printer.
Date Coding: A Key Requirement for Modern Manufacturing
Printing expiration dates is one of the most important tasks in modern industrial product marking. Whether for food, beverages, cosmetics, pet food, pharmaceutical products, or chemicals, almost every product must be marked with a best-before date, expiration date, batch number, lot number, or other production-related information.
These markings provide transparency and safety for consumers. For manufacturers, they are an essential part of quality management, traceability, and regulatory compliance. As a result, modern coding and marking systems must deliver reliable, durable, automated, and cost-effective printing, even on high-speed production lines.
Today, it is no longer enough to simply print a date. Modern production environments require flexible systems capable of processing variable data automatically, connecting to ERP and warehouse management systems, and integrating seamlessly into digitalized production lines.
Printing Best-Before Dates, Expiration Dates or Use-By Dates?
Different terms are often used interchangeably in everyday language, even though they have distinct legal meanings. Common search terms include:
- Print expiration dates
- Print best-before dates
- Print best-before date
- Print expiration date
- Mark use-by dates
- Print expiry date
- Print production date
- Print batch number
- Print lot number
- Print batch code
- Product marking with date
- Print date codes on packaging
For manufacturers and service providers, the challenge is always the same: the required information must be applied automatically, accurately, and permanently legible to the product or its packaging.
Why the Right Date Coding Technology Matters
Many companies initially search for a printer to print expiration dates. In practice, however, it quickly becomes clear that the real challenge is much more complex. Choosing the right technology depends on factors such as:
- Packaging material
- Production speed
- Print resolution
- Environmental conditions
- Available installation space
- Variable data requirements
- Traceability requirements
- Integration into existing systems
Printing a best-before date on a plastic cup places different demands on the printing system than applying an expiration date to a shipping carton or a batch code to an aluminum container.
For this reason, the focus should not only be on selecting the printer, but on finding the right coding solution for the entire marking application.
Thermal Inkjet (TIJ): The Modern Solution for Printing Best-Before and Expiration Dates
In many manufacturing facilities, Thermal Inkjet (TIJ) systems have become the preferred technology for date coding. TIJ printers use high-resolution printheads to produce sharp, highly legible markings, even with very small characters. They are particularly well suited for printing:
- Best-before dates and expiration dates
- Batch numbers and serial numbers
- QR codes, DataMatrix codes, and GS1 barcodes
The excellent print quality ensures that even the smallest characters can be read reliably. At the same time, companies benefit from low maintenance requirements, as many systems use easily replaceable ink cartridges. For modern packaging lines, TIJ is often the most cost-effective solution for printing expiration dates and variable production data.
CISS Systems for Low Operating Costs
Where high print volumes are required, systems with a Continuous Ink Supply System (CISS) become an attractive option.
These solutions combine the advantages of high-resolution inkjet printing with external ink reservoirs, making large-scale production both efficient and economical.
Typical applications include:
- Carton coding
- Secondary packaging
- Shipping cartons
- Production marking
- Logistics coding
Especially in high-volume production environments, CISS systems can significantly reduce operating costs.
Piezo Inkjet for Large Print Formats
When expiration dates need to be combined with larger graphics or additional information, piezo inkjet systems are often the ideal choice.
This technology is particularly suitable for:
- Outer packaging
- Pallet marking
- Large character printing
- Carton printing
- Logistics codes
In addition to date codes, these systems can print logos, graphics, large barcodes, shipping information, and other variable data directly onto the product or packaging.
The wide range of compatible inks makes piezo systems an excellent choice for demanding industrial applications.
Laser Marking for Permanent Identification
Laser marking is another reliable method for applying expiration dates and other production-related information.
Unlike inkjet systems, laser technology does not apply ink. Instead, the laser permanently modifies the surface of the material.
Key advantages include:
- No consumables
- Permanent marking
- High protection against counterfeiting
- Low maintenance requirements
Laser systems are particularly suitable for glass, metal, certain plastics, cans, and closures. For traditional carton and packaging coding applications, however, inkjet systems are often the more flexible and cost-effective solution.
Printing Expiration Dates in Automated Production Lines
As manufacturing becomes increasingly digitalized, the demands placed on modern coding and marking systems continue to grow.
Today, production data is often transferred automatically from:
- ERP systems
- Warehouse management systems
- MES solutions
- Production databases
As a result, manufacturers benefit from:
- Automatic date calculation
- Error-free batch management
- Reduced operator errors
- Greater process reliability
- Complete product traceability
Especially in environments with frequent product changes or small production batches, digitalization delivers significant efficiency gains. Modern coding systems communicate directly with higher-level software to ensure that the correct data is always printed on the product. Manual intervention is minimized and the risk of errors is significantly reduced.
At the same time, production data can be recorded and documented in real time. This greatly simplifies audits, quality control, and product recalls while providing the foundation for complete digital traceability.
Robotics and Intelligent Coding Systems
Robotics is also playing an increasingly important role in product marking and date coding.
Modern robotic cells can position printing systems flexibly for different products or automatically orient products for marking. This allows even complex geometries to be coded reliably.
Combined with vision systems, sensors, and automated quality inspection, fully digitalized coding processes become possible.
Typical applications include:
- Food production
- Pharmaceutical packaging
- Automotive manufacturing
- Electronics production
- Logistics centers
The combination of robotics, inkjet technology, and digital data management opens entirely new possibilities for efficient and reliable coding processes. Print quality can be inspected automatically, defective products removed from the production line, and production parameters adjusted in real time.
These capabilities offer significant advantages in terms of productivity, quality assurance, and process stability, particularly in high-speed production environments or where products frequently change.
The Right Solution Starts with Professional Consulting
If you want to print expiration dates, automatically apply best-before dates, or integrate date coding into existing production processes, you should look beyond simply purchasing a printer. Choosing the right complete solution is what truly matters.
Every production environment has unique requirements regarding materials, production speeds, data management, traceability, and automation. For this reason, every successful coding solution begins with a detailed analysis of the specific application.
Whether you choose high-resolution TIJ systems, cost-efficient CISS solutions, powerful piezo inkjet technology, or laser marking depends on numerous technical and economic factors.
Professional consulting considers not only the printing technology itself, but also integration into existing production lines, connectivity with ERP and automation systems, and future requirements related to Industry 4.0, robotics, and digital manufacturing.
The result is a future-proof coding solution that reliably and economically prints best-before dates, expiration dates, batch numbers, and other production-related information with consistently high print quality.
