Why Ink Matters: Choosing the Right CIJ Ink for Reliable Traceability
When manufacturers invest in a continuous inkjet (CIJ) coding system, the focus often falls on the printer itself. While printer performance is very important, the ink plays an equally critical role in determining whether codes remain clear, durable and consistently readable throughout production and beyond.
In fact, many common coding issues can be traced back to ink selection rather than the printer. Choosing the right ink can improve code quality, reduce waste, minimise downtime and help ensure compliance with industry traceability requirements.
At Linx, we view ink as a vital part of the overall coding solution. That’s why we develop and manufacture our inks in the UK and continuously create new formulations designed to solve real-world customer challenges.
The Hidden Costs of Using the Wrong Ink
Not all inks perform the same way. An ink that works perfectly in one application may struggle on another due to differences in packaging substrates, environmental conditions or downstream processes such as freezing, exposure to moisture, shrink-wrapping, transportation and handling.
Using an unsuitable ink can lead to:
- Poor adhesion on challenging materials such as plastics or coated packaging
- Smudging when products are handled before the code has fully dried
- Reduced code durability when products are exposed to moisture, chemicals, sterilisation or abrasion
- Poor contrast and readability, making traceability more difficult
- Increased waste and rework due to rejected products
- Unplanned downtime caused by coding performance issues.
Factors such as line speed, temperature, humidity, condensation, packaging coatings and product handling requirements can all influence ink performance. The result is that successful coding depends on matching the ink to the application – not simply selecting a printer and assuming any ink will suffice.
A CIJ Ink for Every Application
Different applications require different performance characteristics. That is why Linx offers a comprehensive portfolio of CIJ inks, developed to meet a wide range of coding requirements.
General Purpose Inks
Designed for everyday coding applications across a variety of substrates, these inks provide reliable performance, are fast-drying and have excellent readability.
Plastic Substrate Inks
Rigid and flexible plastics can present unique adhesion challenges. Linx plastic substrate inks are formulated to deliver optimum adhesion and high-quality codes on a wide variety of plastic materials.
Contrasting and Coloured Inks
Where standard black codes do not provide sufficient visibility, coloured and high-contrast inks can improve readability on dark substrates such as rubbers, plastics and metals.
Process-Specific Inks
Some products undergo demanding downstream processes such as sterilisation, retorting, curing, fluid washes or chemical exposure. Linx process-specific inks are developed to maintain code integrity under these conditions.
MEK-Free Inks
Linx offers a range of MEK-free inks that have low odour and are suitable for ‘closed’ environments where fumes cannot vent freely and have an improved health and safety profile.
Halogen-free, non-CMR and PFAS-free inks are also available.
Security and UV-Readable Inks
For manufacturers of high-value products, specialist security inks can help support product authentication and traceability while remaining discreet within the production process.
Industry-Specific Formulations
Linx also provides inks developed for specific industry requirements, including beverage, electronics, and other specialist applications.
By offering a wide range of formulations, Linx helps customers find an ink that meets the demands of their production environment, product and customer requirements.
UK Formulation and Manufacturing: Quality You Can Trust
The quality of a CIJ code begins long before production starts. Consistency in ink formulation and manufacturing is essential for achieving reliable coding and printer performance day after day.
Linx inks are formulated and manufactured in the UK, giving us direct control over production quality and raw materials, testing within the printer and in controlled conditions, and supply. This enables us to maintain high manufacturing standards and ensure consistency from batch to batch.
For customers, this provides several benefits:
- Consistent code adhesion, helping to eliminate rework
- Dependable product quality, through accurate, durable codes
- Reliable printer performance, supporting continuous production
By controlling the manufacturing process, we can focus on delivering inks that perform as expected in real production environments.
Solving Customer Challenges Through Ink Innovation
Manufacturing environments continue to evolve. New packaging materials, sustainability initiatives, stricter regulations and faster production lines create fresh coding challenges.
That’s why Linx invests in ongoing ink development. Our teams continually research and evaluate new raw materials, application requirements and industry trends to develop formulations that meet changing customer needs.
When developing inks, factors considered include:
- Adhesion to new and challenging substrates
- Drying performance at high line speeds
- Code durability throughout the product lifecycle
- Regulatory requirements
- Application-specific functionality
- Manufacturing and quality requirements.
This focus on innovation helps ensure that customers can continue to print traceability codes reliably, as their products, packaging and production processes evolve.
More Than an Ink Supplier
At Linx, we understand that reliable coding depends on more than just a printer. It requires the right combination of printer technology, application expertise and ink performance.
By offering a comprehensive range of specialist CIJ inks and continually developing new formulations to address emerging customer challenges, we help manufacturers achieve durable and reliable batch and date codes across a wide range of applications.
Because when the right ink is matched to the right application and the right printer, printing becomes one less thing to worry about.
