A laser mark can be used as an important security feature to avoid the counterfeiting of your products.
Counterfeiting can be defined as illegally making something that imitates an authentic product. This could include consumer products such as handbags, watches and fashion clothing. It can also be consumables such as alcoholic spirits, cigarettes and pharmaceutical products.
Each year, thousands of counterfeit goods are seized. However, with the necessary tools becoming more accessible, the quality of counterfeit products have risen to a point where they are much harder to detect than ever before.
Counterfeiting is a global issue which continues to increase year over year. Some estimates state the international trade in counterfeit and pirated goods could reach close to $1 trillion by the end of the decade.
The impact of counterfeiting can affect the profitability of the legitimate company and its reputation. Fewer goods sold results in revenue declines. And the potential lower quality of the counterfeited goods can also negatively affect a company’s reputation.
Refilling genuine packaging with counterfeit product also has a large impact. While this has typically been seen in the beverage industry, more recent examples include the practice of refilling CBD oil bottles and tinctures.
Anti-counterfeiting measures provide a method which can reduce or eliminate the ability of a counterfeiter to copy a product.
Coding and marking can be the surest way to protect against counterfeiting today. The best coding and marking solutions provide excellent protection against counterfeiters and the robust, permanent and complex codes they produce are increasingly the best defense.
What are the benefits of using laser coding to avoid counterfeiting?
Of all the different coding technologies, laser coding is often most attractive to companies concerned about counterfeiting because a laser coder can print permanent, high-quality codes at all line speeds onto a wide range of substrates including glass, coated metal, labels and plastic.
Laser codes can’t be rubbed off, making them the ideal solution for traceability and anti-counterfeiting.
Whether you are a small operation or a large-scale manufacturer, consider a laser-based marking solution to protect your business. It will provide you with high-quality codes, save you money in the long term and increase your protection against the counterfeiters who seek to profit from your brand.

A different laser technology has been getting some new press lately, thanks in part to growth in the Fast-Moving Consumer Goods (FMCG) market. Fiber lasers aren’t new, but their application in the consumer packaged goods market has definitely hit a growth spurt. Product packaging is evolving and making use of different materials, like High Density Polyethylene or HDPE which is most desirable for its high-quality presentation, durability, and versatility in handling liquids from automotive oils to shampoo and specialty drinks. It’s no mistake then that the fastest growing laser marking technology is fiber laser which has the ability to mark directly onto HDPE as well as a range of materials not previously well served with CO2 lasers.
What then, are the other key differences between CO2 and fiber lasers?:
Fiber lasers don’t necessarily use more power, but do use power differently. The laser beam produced is in a different part of the light spectrum and is a much tighter beam. This is what allows the laser to mark materials that other lasers can’t, such as HDPE. Or, mark into other materials better such as rubber and metals.
By comparison, fiber laser can be quite small and compact. Instead of a bulky tube of gas, fiber lasers use optical fiber as their lasing medium. The exact science of it can be quite detailed but the bottom line is: these lasers are compact and have a small footprint. This allows for easy and convenient installation to the packaging line.
Like most industrial equipment, fiber lasers do come with their own set of safety requirements which can be managed safely through proper guarding and training.

It is estimated by the US Grocery Manufacturers Association that over half of recalls cost companies over $10M. In addition to the financial implications, recalls for defective products could be harmful to the health of your customers and ultimately damaging to your reputation. These two major factors support the necessity of product identification in the form of date codes, lot codes and batch codes to track and trace in the event of a recall.
Two common automated marking and coding solutions for food packaging are continuous inkjet and laser coding. Which solution best fits your application is dependent on a number of factors. To help you in this evaluation process, we have outlined a few consideration questions:
Continuous Inkjet Considerations
Continuous inkjet (CIJ) can mark onto virtually any substrate type, rounded or flat, ranging from plastic bags, glass jars, metal cans, paper cartons and more. Because of the variety of ink types and colors available, you can achieve a high-contrast mark on nearly any color packaging.
Laser Coding Considerations
Laser, by comparison, creates a permanent mark on most surfaces although not all packaging types will guarantee a high-contrast batch, lot or date code. The etched marks from laser will last, although on clear plastics and glass the coding may not be as easily visible as black ink from CIJ.
Continuous Inkjet & Laser Coding Considerations
Accurate batch, date and expiration codes are essential for customers and retailers alike. If your production lines perform multiple changeovers for different products each shift, this leaves room for errors. Leading CIJ and laser solutions have features for storing unique, variable messages and icon-based interfaces that can be operated without extensive training for message creation and retrieval. Reliable, accurate coding methods will keep your line running in uptime and ensure speedy recall of products in that event.
If your products have high retail value, they may be susceptible to counterfeiting. There are internal tracking and security codes that can be made on a product discreetly, that are only visible under certain circumstances by the manufacturer to verify authenticity and product origin. For CIJ, one option is security UV inks that are nearly invisible until exposed to UV light.
The low-contrast, permanent marks created from laser etching are a benefit in the case of anti-counterfeiting codes. Codes can be applied to packaging in an inconspicuous location without compromising the appeal of the packaging design.
These are only a few considerations to keep in mind when selecting between continuous inkjet and laser coding for your food or beverage packaging line. For more information on how coding ties into food safety and traceability, download our full whitepaper.
Coding for Safety & Traceability in the Food Supply Chain: A Comparison of Continuous Inkjet & Laser Coding
(March 1, 2017) - Linx Printing Technologies is launching two laser coders that will open up the benefits of laser technology to more companies and applications. Key benefits of the new Linx CSL range are even faster printing speeds and greater versatility, making the coders ideal for a wider variety of products. Quicker and easier installation and set-up help to make laser coding simpler and more accessible.
The Linx CSL10 (10 watt) and CSL30 (30 watt) laser coders feature a new, more powerful processing board with the ability to relay the message from the control unit to the marking head more quickly, delivering higher speeds. Ideal for the requirements of high speed packing and bottling lines, the coder can handle complex messages and graphics without any loss of quality. Both models apply crisp codes onto many different packaging materials including coated paper and card, plastic, glass, rubber, coated metal and anodized aluminum.
A new marking head has been introduced for wide web applications, enabling the coders to code across multiple lines using just a single laser where previously two machines would have been required. An area of up to 440mm x 600mm can be coded – ideal for applications such as flexible sheet for lids.
In addition, a wider range of marking heads and positions mean that the Linx lasers offer over 20,000 standard configurations, and can therefore be tailored to the precise requirements of each coding application. This unique feature makes the Linx CSL10 and CSL30 the most versatile laser coders available. Tailoring the laser application to the customer’s precise requirements means optimal use is made of the laser system, contributing to the lasers’ long tube life.
An increased choice of conduit lengths – 3, 5 and new 10m sizes – together with a more flexible conduit design, detachable marking head, connectors and conduit, and quick disconnect umbilical cable, have made installation of the coders easier, particularly where the lasers cannot be placed close to the power supply or where space is limited. These same features speed up service times and make it simpler to relocate the machines in the factory.
Both models can be specified in an IP65 version, allowing the coder to operate in harsh, wet and dusty environments such as frozen, dairy, beverage, chemicals and construction.
Both the Linx CSL10 and Linx CSL30 retain the proven features of Linx laser technology including a highly efficient operating system that delivers one of the longest tube lives on the market – around 45,000 hours – and its unique VisiCode® function for producing unsurpassed high quality codes on glass and PET while reducing energy usage by up to 50%. An enhanced version of its LinxVision® operating system allows for fast and simple set-up that minimizes errors.

We all know that bigger is better and we all want more. It’s what we do, right? If 10 of something is good, then getting 20 of it is great, and 30 of it is fantastic! Well that is up until we have to pay for it anyway. When cost becomes the focus of our attention, it’s safe to say that less is more. Regardless of what we are buying, we need to look at what we need, and this tampers down all the enthusiasm for bigger is better. A Bugatti Veyron could get me to the office faster than almost any other car on the road, but with a growing family that spends its time in the Suburbs and semi-rural areas, a minivan with a bunch of cup holders ranks higher on the “needs” list.
With laser coding we should take needs into consideration in each application, and power may or may not factor into it. Yes, lasers can really power up if you want to go looking for power. While much of the technology has consolidated, choices in power ratings seem to keep increasing. In some respects it’s almost as if there is a nuclear arms race in laser power rating. Sure you have 10 watt lasers in your widget plant, but the guy on the other side of the business park just got 50 watt lasers on his bottling lines. You might be missing something, and need to upgrade, right?
Probably not, and here are some straight forward concepts to keep in mind with laser coding and power ratings. First, you are going to pay for power. No if and or buts about it, regardless of laser type, as the power rating goes up, so will your cost of equipment. Economically, it’s in your interest to get the lowest power laser possible.
Second, what power really gets you is speed on production lines. Often power is thought of as “burning harder” into materials and while there is truth to that, the reason we burn harder is most likely to keep up with production rates. Low power lasers can mark most product and packaging materials…if we give them enough time. We are talking seconds for some materials, whereas for many coding operations a typical message might code in the range of 100 milliseconds, or even less for high speed lines.
So the bottom line becomes, what material are we marking and how fast is it moving through production? When we dial in on these factors with testing and sample codes, we can narrow it down to the lowest power option. This will help make the project justification and keep your line operators from slicing open the new plastic bottles on your brand new conveyors.
If you are near the top of the chosen lasers output, there is a question left to ask and it might make the case for tweaking up the power. So, what does your crystal ball say? If your line speeds and production might increase, or your materials might change, a power upgrade might be sensible. Typically, lasers last a long time without much intervention. So while some coding technology can get cycled on a regular basis, you want to plan ahead with lasers.
At Diagraph Marking & Coding, we’ve got the people and experience to work with you, in your plant and with your crystal ball, to work out the best, but not necessarily the biggest, solution. We’ll focus on coding for cost, letting you manage your business.
Step one of a manufacturer’s game plan for packaging compliance is to understand your manufacturing code and print application requirements, in order to pick the product identification solution that is best for your needs.
What kind of information needs to be included in your print message? In many cases, especially in food and beverage, consumer-readable information must be included for buyers to determine freshness. In other instances, government and global regulatory agencies have set the requirements for manufacturers to adhere to. In order to meet packaging compliance, manufacturers may need specific product information, manufacturing codes, and barcode information, including:
Once specific print requirements and message placement are determined, manufacturers should also consider their application specifications. What type of packaging substrate does a manufacturer’s product or products use? What other processes in your material handling are occurring to take into consideration? And what kind of line speeds are they trying to achieve?
It will be important to understand which criteria your application falls under for a marking and coding partner to best match you with a solution that will deliver your desired results.
After determining the print requirements and application specifications, manufacturers can look at the available product identification solutions and select a technology that is right-sized for their material handling set-up.
A full portfolio range of product identification solutions are available to manufacturers including:
The tables below show how each type of product coding technology is suited to fill specific manufacturer print and application requirements.
In order to achieve packaging compliance, it’s necessary to pick the best marking and coding technology for the product in question. By taking the time to understand print message and application requirements, manufacturers can begin to compare compatible product identification methods and equipment.
Picking the best product identification solution is one step in a multi-step process to achieve packaging compliance. After the information has been applied to your product, message validation is the next step.
Ensuring manufacturing codes are printed on products is not enough by itself to achieve packaging compliance. The codes need to be validated to make sure they are present, accurate, and scannable.
There have been many advancements in product identification and machine visioning technology that have enabled manufacturers to automate the monitoring of real-time print quality. Scanners and vision systems are common components added to the production line postprint to inspect and report any illegible codes or incorrect stock.
Manufacturers know their requirements best, and working with a partner that offers a portfolio of all types of product coding technology will give you a fair assessment of the best solution for your needs. It’s also wise to choose someone who can provide support beyond installation for maintenance and servicing as age and wear and tear occur on your equipment. A reliable partner will also provide training for your maintenance staff should you choose to be as self-sufficient as possible.
However, there are still more steps to ensure manufacturers achieve packaging compliance.

You went to the trouble to build a factory, develop a product, built the production line, worked out operations, purchased all the raw materials, toiled hours longer than you should have on the perfect package design, and then do what at the end of it? Smear some code on the corner that’s supposed to stand out to the customer? Good news – you don’t have to deal with smudged codes anymore.
To avoid smeared, smudged and illegible date and lot codes, turn to the high print quality made possible from today’s scribing lasers. Yes, there is a past where lasers were producing a “dot matrix” type of code too, but thanks to better controllers and development, we’re past all that history. Today’s lasers fire a single beam that is digitally controlled and “writes” across the surface being marked with smooth fonts, high quality graphics and bar codes when needed.
A lot of end user packaging is coated paper and, when coupled with scribing lasers, produces exceptional print quality. No, lasers won’t print in color – that’s a technology off in the future. We achieve the high contrast by ablating away the top layer of print exposing the lower bleached or kraft paper color.
Simple messages are a slam dunk in this type of application, but complex messages such as those with bar codes or graphics are not too difficult either. They do require some design, and a good software package to drive the laser. Most likely you will want to control separately the different elements of the message. This allows setting different mark delays and times to correctly image those elements on the package.
Using the Linx Laser Systems, Diagraph can help you produce great marks on your products. We have the latest in lasers and software to produce the best mark without overpowering, or overselling, the application.
