Continuous inkjet printers (CIJ) use super-fast drying solvent-based inks. One of the technology challenges presented by these inks is that they aren't too particular where they dry. With CIJ technology, the formation of drops from an inkjet stream creates a mist (or satellite drops) which builds up a layer of ink over time on the components inside the CIJ print head, causing print failure. Routine cleaning of ink with solvent from the components in a print head is required to maintain best print quality and uptime.
Some CIJ manufacturers developed an automatic solution to clean the print head by adding a solvent spray cycle in the print head. Some solutions add components to the print head to attract the ink mist which is then washed out with solvent. One assumes operator time will be reduced with an automated process. However, that is not the case. An automatic cleaning process still relies on manual intervention for the following steps:
Cleaning processes that promise to protect the user from solvent fumes still expose the operator to fumes when disposing of the solvent.
CIJ users assume a cost of ownership savings with an automatic cleaning feature. Note that you CANNOT print when cleaning a print head. Automatic cleaning requires solvent flowing in a set cycle (usually takes 10 to 17 minutes) and cannot be interrupted once begun. The automatic function produces excess solvent waste compared to manual cleaning.
Linx 8900 series CIJ systems are designed for visual inspection of your print heads with an expectation to manually clean it in a 5- to 10-minute process every 100 starts/stops or 3 months. Our print heads are kept cleaner by being fully sealed and by using a unique flushing sequence at both start up and shut down.

The final step in your production process can often easily be overlooked. After rigorously completing all the upstream processing, packaging and coding processes, the final palletized product seems to be a small step before crossing the finish line. However, labeling at the pallet level is a crucial process for identifying palletized products being shipped to retailers.
Imagine this: You’re completing a custom job for products specific to one regional retail chain. To differentiate the pallets for the custom job from your standard products, you plan on printing the identifying batch information on the license plate label and applying it to the outside of the shrink-wrapped pallet. When the time comes, your shipment is sent to the retailer only to discover that the products sent are not the custom printed containers they ordered. Now not only is your relationship with this retailer tarnished, but you are on the hook for reprinting all of their products at your own cost.
This scenario might sound familiar if you’re still in the business of manually applying labels. Some level of human error is always a risk and it can be a costly one. Ensuring a consistent, accurate label on every pallet that leaves your facility doesn’t have to be a trying task. It is possible to guarantee proper label placement while also avoiding common safety issues often occurring from the entanglement of the labeler in the pallet shrink wrap.
Our pallet labeling experts at Diagraph have complied a helpful guide for assessing automated pallet labelers for your production line. This guide steps through the main questions you should ask when evaluating your pallet labeling automation process and reviews the top areas of consideration you should work through before you make any kind of investment.

Errors can create downtime and missed deadlines. In today's environment, extended downtime is not something a company can afford to have happen. It is vital to understand why errors are occurring and to keep those coding errors to an absolute minimum. If an error is made at the start of the process but not detected until the end, the cost of rework and rescheduling reduces profits.
Mistakes can and do happen. Below are some of the main reasons coding errors occur so frequently.
Of course, it is a good practice to audit coding errors and analyze their causes. This can pinpoint clear actions for improvements such as individual or group training requirements or identify which equipment needs updating or replacing if it has become unreliable.
Eliminating 100% of coding errors is not possible due to the human factor. However, with the wide choice of user interfaces on the market, it makes sense to incorporate as many beneficial features as possible which suit your requirements and workforce. This approach helps reduce operator errors and keeps your downtime to an absolute minimum.
Remember, no one piece of equipment is going to solve your coding errors. You will always need good staff training, teamwork and processes. However, a good user interface that guides employees through initial set up can ensure errors are kept to a minimum. This will go a long way to keeping costs low, reducing downtime and most importantly, keeping your customers happy.
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
The Container You Choose for Your Brew Determines Which Coding Technology You Should Choose
An excerpt from 2016 Comprehensive Guide to Date and Batch Coding in the Craft Brewing Industry
Different types of technology are needed for printing on your primary (bottle or can) package and on your secondary (outer box) package. Continuous ink jet (CIJ) and laser are the most common options for printing date codes, batch codes, other text, graphics, barcodes, QR codes and other codes onto primary beverage packages.
When selecting a coding system for your primary packaging, the first step is to consider what type of material you will be printing on. Keeping in mind that you can reasonably expect the printer to last five to seven years, what types of packages are you using now and do you plan to use in the years ahead? Bottles can be coded with either laser or CIJ systems. Cans are coded with CIJ technology. This means that a craft brewer who wants to be able to code on both cans and bottles will need a CIJ system.
The next consideration that should factor into your coding technology decision is production volume. Download our free guide to view cost comparisons based on the number of bottles and/or cans you fill per day.

Analogue coding technology is still found throughout the meat processing industry, such as hot stamp or roller coders. As a relatively cheap printing solution, these could be used by meat processors to keep costs down on their fast production lines.
Of all the analogue coding technologies available, hot foil stamping is perhaps the most common in meat processing. Our best-of-industry Norwood hot stamp printers are still widely used today. With that being said, relying on analogue based technology can have its drawbacks, and that’s where digital coders come in.
The drawbacks of analogue coding technology
When it comes to analogue coding, the messages that are available for coding are restricted by the amount of information that can actually fit on the die wheel. Therefore, the coders are not as flexible as they could be when it comes to having to incorporate larger messages on the pack. Also, with hot stamp technology, there is a wait for the coder to ‘warm up’ – meaning that valuable coding time is lost through setup.
In an industry dealing with fresh produce where packers need to respond to changing legislation quickly and efficiently, having a technology that needs this amount of time to set up is not ideal in many meat processing lines. Also, errors in coding cannot easily be amended, as codes are manually changed on the die wheel which means stopping the printer, removing the die wheel and replacing individual characters which is a fiddly and time-consuming process. Worn code wheels can also potentially lead to perforation of the packaging, something that could potentially lead to scrappage.
Hot foil stamping is also a contact technology, something that could further constrain the speed of the production line, and even present packers with problems when it comes to maintaining the hygiene of their line.
Digital coding and marking technology in meat processing
SmithersPira has recently examined the benefits of digital coding for many industries including food manufacturing. Their analysis of other industries helps to highlight the advantages of digital coders within the meat processing sector.
For example, when looking at drug production lines, the requirement for frequent and error-free changeovers would appear to be a driver towards the implementation of digital technologies. This is no different in the meat processing industry, where errors in coding could lead to potentially costly downtime or scrappage.
The research also identifies how digital coders can help packers deliver consistent traceability. With late-stage customization for example, when codes need to be added or changed at the last moment, flexibility becomes a primary concern for packers – something that is not delivered as effectively with analogue coding technology. And with a reduction in errors as mentioned above comes more effective traceability.
Not only can all of this be delivered by digital coders, but the non-contact nature of the machinery can help to maintain hygiene and even deliver codes at faster speeds.
Therefore with fewer errors, flexibility, and faster, more consistent coding, digital technology represents a more cost effective solution for meat processors in the long term. And with uncontrollable variables such as adverse weather events, disease outbreaks and increased competition from seafood, meat processors need to deliver codes in an effective way that allows margins to be maintained.
