Marking Coated Card
Coated card is widely used for premium packaging across food, pharmaceuticals and personal care due to its low cost, versatility and ability to be printed with brand and consumer information. However, its smooth or varnished surface can make it difficult to achieve consistent, high-quality codes.
Challenges in Coated Card Marking
Coated and varnished surfaces are semi-porous or non-porous, making it harder for inks to adhere and dry quickly. Slow drying inks can lead to smudging, especially on high-speed lines or during handling and packing.
Coated card products are often saturated colours or bold packaging designs, for a good contrast code a “knock-out box”, contrasting ink or laser code may be required.
What is an Industrial Card Printing Machine?
Industrial printers can code directly onto coated card in any orientation. They can mark variable information as well as printing barcodes, Data Matrix and QR codes onto boxes, trays and sleeves to enable traceability, and convey quality and safety information to the consumer.
The most commonly used technologies for coding onto coated card are continuous ink jet (CIJ) and CO2 laser coders. Each has unique benefits and the one that is right for you application will depend on your product and code requirements.
Our expertise in product and packaging marking & identification can help you to reduce costs and improve production rates.



Primary packaging
Coated card boxes and sleeves are widely used for food products such as frozen meals, confectionery and dry goods, where clear date and batch coding is essential for safety and traceability. CIJ and laser solutions enable reliable marking on these non-porous surfaces, ensuring codes remain readable throughout storage, transport and retail handling.
In cosmetics applications, coated cartons and sleeves provide a premium finish and support the visual identity of the product.
Secondary Packaging and Sleeves
Coated card boxes and sleeves are widely used for secondary packaging such as beverage can multipacks, where clear, reliable coding supports traceability, logistics and retail requirements. CIJ and laser solutions enable high-speed, high-contrast marking of date codes, batch numbers and barcodes directly onto coated surfaces, ensuring codes remain legible through packing, transport and shelf display.
Cartons
Coated card cartons used for products such as dairy-free milk alternatives and juices require clear, reliable coding to ensure product safety and full traceability. CIJ and CO2 laser technologies deliver high-contrast, legible codes for variable information, helping maintain visibility throughout filling, distribution and retail. Their non-contact operation allows marking in any orientation, making it easy to code sloped or irregular carton tops.
What to look for in a Coated Card Coder
Code Content: The code requirements (batch numbers, dates, 2D codes etc.), the size, colour and the desired marking area will affect the coder most suited to your application. Consider a coder that can mark in any orientation for flexible marking on any part of your product e.g on the base. Also think about how the code requirements may change in the future or on other products you produce.
Durability: For durable codes the printing solution you choose must be able to adhere reliably and still be legible through your production and supply chain.
Speed: Ensure the coder you choose can keep up with your production line speed without compromising on code quality.
Production environment: For food production environments that do washdown procedures the IP rating of your coder may be key. If the production space is limited, investigate coders that are compact or can be mounted in different ways to fit the available space.
Available budget: It is vital to consider not only the initial purchase price but also the total cost of ownership, including consumables and cost and frequency of servicing. Can the product be user maintained and repaired?
Reliability: The reliability of your coder is crucial to avoid product rework, scrappage, line downtime and loss of efficiency. Frequent breakdowns can negate any benefits of a lower purchase price coder; look for automatic cleaning or self-service features.

FAQ
Coated card has a smooth, sealed surface that prevents ink absorption, making adhesion and drying more challenging.
Typical codes include batch numbers, expiry dates, barcodes, 2D codes, logos and traceability information.
CIJ is commonly used due to its flexibility and speed, while laser coding may be suitable for certain coatings requiring permanent marking.
A CO₂ laser marks coated card by using controlled heat to alter or remove the surface layer, rather than adding ink.
