Companies using non-contact high speed Continuous Inkjet (CIJ) technology to mark information (including expiration dates) on their product may not be aware that a key component of their marking system – the fluids – also have expiration dates. CIJ fluids need to be able to adhere to a variety of substrates and dry within seconds. Individual ink drops are manipulated by the application of a negative electrical charge. The technology works because the ink is conductive and able to accept the charge for proper placement to generate characters, barcodes, and graphics. CIJ fluids have expiration dates tied to the ability of the ink to maintain the charge for best print quality. Common maintenance of CIJ printers includes periodic refresh of fluids and filters to keep the printer running at peak performance with optimal print quality.
Linx Printing Technologies has introduced two new CIJ models to the 8900 Series, models 8920 and 8940. These new models offer Advanced System Monitoring which provides real time information about the health of the printer. It monitors printer operating parameters which can identify dirty air filters, dirty fluid filters, and ink degradation resulting from harsh environments and aging. Any CIJ printer under these conditions will experience increasingly poor print quality or even printer failure.
Advanced System Monitoring will provide a warning if any of the above items have been observed. Dirty air filters should then be cleaned to allow the printer to maintain proper cooling of electronics. Dirty ink filters can cause lack of pressure and increased wear on the pump, and ink degradation will result in poor print quality. Dirty ink filters and ink degradation indicate that it is time to change out the service module.
The system monitoring allows you to identify and alleviate problems with the printer before they result in poor print quality or costly downtime. This is predictive maintenance in its purest form and brings manufacturers closer to 100% avoidance of unscheduled downtime.

The latest Continuous Inkjet Printer from Linx Printing Technologies, the 8900 Series, reflects the fundamental Linx design philosophies of Ease of Use and Reliability and is supported by the MK11 hermetically sealed printhead that protects all critical components during operation and cleaning.
The most notable of the 8900 Series' features is the auto flush multi-stage process – the industry’s most thorough automatic self-cleaning process – which allows Linx printheads to run cleaner for longer. Bonus benefit – less solvent waste! Few competitors flush both nozzle and gutter, leading to longer start-ups and more frequent printhead cleaning. Comparatively, older competitor printheads require a scab of ink to form on the nozzle to keep their ink line sealed or a mechanical screw to join the nozzle to the gutter to keep air from fluid lines during shutdown.
In the unique Linx printhead auto flush process, both nozzle and gutter are solvent cleaned then left to dry with a vacuum purge. The head feed valve closes and stops nozzle weeping, leaving the printhead clean and dry for a period of storage or an overnight stop. This entire process is initiated with a simple press of a button, cutting out time needed for operator shut-down procedures and increasing productivity.

(Simplified for demonstration)
As a result of the easy-to-use, push-of-a-button auto flush system, operators can pick up where they left off, with full confidence that the Linx 8900 will start-up quickly and easily without additional cleaning. The process improvements have been tested and reveal with typical inks and in typical application environments, customers can expect 100 starts and stops without the need to clean the printhead. Testing actually found 3 months as typical, and in some cases can go up to 6 months.

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.
CO2 Versus Fiber Laser Feature Comparison
Comparison of CO2 and Fiber Laser Marking Materials
The good news in the FMCG packaging and product identification market space is that there are lot of new materials and innovative packaging designs. Even better, Linx Printing Technologies has introduced a fiber laser with easy integration, reliable operation, and the flexibility to deliver high quality codes across the widest range of materials for both static and dynamic applications. This durable product, which includes the IP54 rated marking head, enables the coders to operate in more challenging environments with the fiber laser beam source lasting more than 100,000 hours.

Did you know there were 80 GMO labeling bills introduced in 20 states in 2015? On July 1, 2016 the first GMO labeling law will go into effect in Vermont. The Vermont law requires raw agricultural commodity and processed food producers who sell food products in or into the state of Vermont to mark the lowest saleable unit of food packaging with a disclaimer that clearly and conspicuously reads “produced with genetic engineering.”
Although the labeling message requirement is clear, the law does not specify exactly how manufacturers need to apply the mark to the packaging container. Determining how to apply the mark is entirely up to the manufacturer’s discretion.
Moving forward, food producers need to keep a keen eye on the changing regulations regarding labeling of food products containing genetically modified organisms (GMOs). Unless or until there is a federal law regarding labeling, individual states make the rules on whether or not products sold in their state need to have labeling that includes warnings such as “Partially Produced with Genetic Engineering”. Companies need to decide whether to change their formulations to eliminate GMOs, adjust the geographical markets they sell into, or modify their labeling to meet individual state requirements. The path of least resistance and expense will usually be to change the labeling.
If your product has regional or national distribution, how do you manage specific variable information for sales to a specific state? Diagraph provides a solution with its Linx 8900 Series Continuous Inkjet (CIJ) printers.
If you can use the same GMO call out to cover the requirements of all the regions you sell into, then you can create, store, and easily select the GMO message to be printed onto your product. If different GMO messages are required, you can choose to print all of the necessary GMO messages on each package or easily create different messages and select the appropriate one for a specific manufacturing run. Regardless of the flexibility you need and the type of packaging material you are marking on, the Linx 8900 Series has you covered.
The 8900 family of CIJ printers is capable of printing between one to five lines of text, logos, and barcodes, and is designed for maximum efficiency and minimal effort. The stainless steel cabinet boasts a minimum IP55 rating, which makes it suitable for a wash-down environment. The 8900 Series printers are designed to run reliably and feature the ability to program 4 to 50 production line settings and up to 1,000 unique messages to enable quick and painless change overs and message updates.
With easy change overs and high quality, high speed print, companies can easily add any required GMO text to existing packaging using Linx CIJ.
Although CIJ technology is ideal for meeting nearly every GMO labeling need, there are a variety of technologies available to you to stay in compliance with the law. All-electric label applicators and thermal inkjet printers may be good alternatives depending on your operation. Contact us today for a free consultation to determine which technology is best suited to meet your unique needs: 800-722-1125 or email info @ diagraph.com.
Diagraph is now offering a newly formulated non-porous ink in an improved 45Si cartridge that will offer Thermal Jet Series technology users greater print quality on some of the most challenging non-porous substrates. Some of the enhancements that make the TJNPMX cartridge the go-to choice for tough non-porous applications include:
3x Darker Print
The new formulation found in the TJNPMX cartridge allows for print messages up to three times darker than the standard TJNPM non-porous ink offering. This allows for greater contrast and improved barcode scan-ability.
2x Greater Throw Distance
The improvements found in the 45Si cartridge allow for a print throw distance up to 3/8”, enabling manufacturers with low volume operations to consider the Thermal Jet Series technology solution as an alternative to traditional continuous inkjet (CIJ) solutions.
Extended Decap Times
The TJNPMX ink formulation combats a common issue found with HP Cartridge technology solutions – printheads that sit idle between prints tend to clog and need to be de-primed to get the print quality back to an acceptable standard. The new formulation allows for excellent decap times lasting up to several hours, assuring consistently high print quality over time.
Non-porous substrates that work well with the TJNPMX formulation include:

Top 3 Tips for Choosing a Coding Provider
It can be difficult to choose a marking, coding and labeling equipment provider with so many available. These tips will help you find the best provider for your business:
1. Total Cost of Ownership (TCO) – This seems like an obvious consideration, but year after year manufacturing companies new to marking and coding make equipment purchases that cost them big over time. Ensure you understand your ongoing costs for equipment parts, consumables and service as well as downtime costs associated with routine maintenance before making a purchase. TCO varies widely from manufacturer to manufacturer.
2. Ease of Use – Can your line operators easily change messages, refill fluids or labels and perform preventative maintenance with as little impact to uptime as possible? Equipment that is the easiest to use and most reliable features design elements that are engineered directly into the machines (as opposed to being applied after-market).
3. Service Support Structure – Coding providers who are most responsive to your needs have field service operations dedicated to your neighborhood. Look for providers that offer telephone support and have layers of expertise available within the organization to ensure that your unique application gets every consideration necessary.

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.

How do you Print on a Sachet or Stickpack?
By Steve Dods, Automated Labeling Products (ALP) & Thermal Transfer Overprinter (TTO) Products Manager
Sachets are packets or sealed pouches that contain liquids, gels, or powders and typically sealed on four (4) sides. Stickpacks are tube-like packaging that is sealed on two ends with a continuous seam side. These convenient packaging methods are highly utilized in the food and beverage additive markets, but can be seen in pharmaceutical as well as cosmetic industries.
This packaging type requires a specialized system to form the packaging receptacle, fill the product into the packet, and seal the ends to secure the product for transport. These systems are known as FFS, Form, Fill, and Seal machines, and they come in two different varieties. Once is Vertical, or VFFS, and the other is Horizontal, or HFFS. Vertical uses gravity to aide in the filling process, where horizontal is generally high speed by using mechanical methods for filling.
Since sachets and stick packs can be sold individually, there can be the need to print information about expiration date and lot code onto the individual products. Since it is far less accurate to accomplish this task once they are filled, due to irregularities in shape and placement control, it is done "upstream". Upstream of the fill process is where the film or web is unwound from a large roll. This is the best location to mark and code the product - before it is individualized in the process. There are many ways to accomplish this type of date / lot / id coding, but there is one that stands out amongst the rest.
In marking the products in the web matrix, there are several "lanes" of product on the master web. That means higher fill rates by handling multiple products in each indexing move through the process. A typical number of adjacent products is 5 or 6, but some are as few as 4 or as high as 12. In rare instances, lanes numbers exceeding 12 have been realized. Due to these high number of prints required at each indexing interval, traditional methods of marking are usually ruled out.
Of the possible marking methods, there are a few that have been used in practice. One is to brute force out the marking process by using multiple ink jet print heads. This is somewhat difficult to manage, as there is a requirement for non-porous ink to mark the web, which tends to have issues with the short decap time and fast dry times that can clog or require higher maintenance. Most objections from OEM FFS manufacturers and end users is the mess and chemicals in close proximity to dispensing foods and powders.
Another method is to use TTO (Thermal Transfer Overprinting) to traverse across the web to mark an indelible print using a clean ribbon method. This works, but the throughput rates suffer due to the time it takes to sweep laterally across the web each time. On the same idea, there are traversing ink jet solutions as well. They again suffer from the points above, and additionally add the time component for the sweep across the web.
The best method that eliminates the weaknesses of the aforementioned methods is the multi-lane intermittent (MLi) TTO system. The MLi incorporates a plurality of print heads to match the number of lanes requiring print. It utilizes one ribbon, to avoid multiple consumables running out at various, unsynchronized times. It is able to print very quickly, since each head can print simultaneously, each covering an area up 100 mm (across the web) x 52 mm (in the direction of web movement). Systems like these may have a slightly higher upfront price, but more than make up for it in much higher uptime and ease of use. Maintenance is fair less, and it requires little skill to perform daily operation functions, since loading a ribbon is straight forward.

Common GS1 Barcodes Pictured Above. The following can be printed by Print and Apply Labeling and most High Resolution Inkjet Technologies:
Barcodes: UPC-A, EAN-13, UPC-E, EAN-8, GS1 DataMatrix, GS1 QR Code, GS1-128, ITF-14
GTIN Types: GTIN-8, GTIN-12, GTIN-13, GTIN-14
Many major retailers and distribution centers require manufacturers to display important information on all four sides of cartons and cases that are intended for backroom storage purposes. This offers retailers ultimate flexibility for their inventory management programs.
The following information is important to effectively manage inventory:
· Product Name and Other Identifiers
· Machine Readable Barcode
· Best By Date Code
· Handling/Storage Instructions
· Lot/Batch Code
Having this information visible on your box is usually not enough. Manufacturers need to ensure that this important information is large enough and clear enough to read from a distance.
4-Side Print Solutions
Unfortunately there are not any one-size-fits-all solutions to accomplish four-sided printing. Flexographic and lithographic pre-printed boxes are not practical for the important variable information needed with every shipment (i.e., best by date and lot/batch code). Manufacturers can turn to a combination of pre-printed information and print-on-demand information if flexographic elements are required. However, complete print-on-demand solutions offer manufacturers the greatest flexibility in terms of cost and supplies.
Print and Apply Labeling 4-Side Print Solutions
Because manufacturers have more options when choosing to use a labeling solution for their four-sided print requirements, the best solution for your particular operation depends largely on the speed of your line and your product throughput. The most efficient option in terms of the equipment required would be to opt for two opposing E-FASA (swing arm) print and apply labeling machines. One machine would apply the label to the front and the side of the box while the other would apply to the opposite side and the rear panel. This solution does not require a bump turn material handling mechanism.
The Diagraph PA/6000 with E-FASA tamp applicator module offers the greatest flexibility for manufacturers. The all-electric design frees the labeler from shop air, allowing it to be placed anywhere on the packaging line. Additionally, the servo motor and smart sensing technology unique to the PA/6000 system ensure that labels are precisely placed on time, every time.
If retailers and distribution centers require flexographic and lithographic printed barcodes, you can more easily manage pre-printed label stock than a large pre-printed box inventory. Utilize flexographic printed labels for all information that will remain the same and utilize the labeler’s printing capability to print the important variable information on demand. With that being stated, it is important to point out that printing barcodes using a wax-resin ribbon and a thermal print head onto consistent label stock is a highly reliable print method. The recommendation to get pre-printed label stock depends entirely on retailer requirements, but is not necessary if you want the print and apply labeler to handle your entire print message – including the barcodes.
Large Character Inkjet 4-Side Print Solutions
Many manufacturers can get away with only displaying information on one or two sides of a case. To accomplish print on two opposing sides, manufacturers need inkjet printers installed on opposite sides of the packaging line. At Diagraph, our high resolution large character inkjet system – Diagraph IJ4000 – can drive printheads on opposing sides of a single line from a single system. The unique centralized ink delivery system in the Diagraph IJ4000 allows floor operators to monitor and change fluids from a single location rather than having to monitor each individual print head.
Additional material handling is required when setting up your packaging line for four-sided printing. A “bump turn” material handling method is required to rotate the box 90° to present the remaining two panels for printing. Two additional opposing printheads need to be installed further down the line, positioned after the bump turn mechanism, to print on the remaining panels. Four-sided box printing can easily be accomplished using the Diagraph IJ4000 once the bump turn mechanism is in place on the packaging line. A single IJ4000 system can drive all four required printheads from a single system, allowing up to a 2” print height for the printed information.
Printing variable information using a Diagraph IJ384e printhead offering a maximum of 2” characters satisfies size requirements for most retailers. If larger characters or a larger print area is desired, manufacturers can opt for the Diagraph IJ768e printhead, which offers up to 4” of print height. A single Diagraph IJ4000 system can drive two IJ768e printheads, which means two systems would be required for a four-sided printing application. Many of our customers opt for the IJ768e 4” printhead to take advantage of the larger print area and future-proof for expanding retailer requirements.
The Diagraph IJ4000 system prints high resolution text, graphics and machine readable barcodes, including GTIN, ITF and GS1 varieties.
Additional Quality Assurance Measures
Both high resolution inkjet and print and apply labeling technologies can print machine readable barcodes with high quality resolution. Many of our customers install a fixed mount barcode imager to test the barcode quality. This information is sent to a PLC which reads the good or bad output from the barcode imager and stops the conveyor when a barcode gives a bad result. This extra quality measure ensures that only readable barcodes reach retailers.
