  • Avoid Labeling Mistakes by Removing Plant Air Posted last month
    All-electric label applicators revolutionize the packaging industry by eliminating the reliance on plant air, providing precise applicator control for consistent and accurate label placement and ensuring secure label control for various label sizes.
  • Is training production line workers creating a challenge? No problem!  Posted 6 years ago
    Companies rely on engineers or technicians to keep production lines up and running. These job functions are essential to hitting production targets, so it is key that their skill level on equipment is proficient. When making the decision to replace this equipment, the amount of time and money that will have to be invested in training your labor is a major deciding factor.
  • How do I get labels to stick in hot and humid environments? Posted 3 years ago
    Something to be aware of when considering using labeling for product identification in a hot or humid environment is that labels are sensitive to temperature, making facility environment temperature a determining factor in choosing what label material to use on a product.

(March 1, 2016) – Diagraph ( announces the launch of the IJ4000 high-resolution large character impulse inkjet system for printing alphanumerics, barcodes and graphics onto porous substrates. The cost-competitive printer combines industry-leading barcode decode-ability, industry-leading system durability and industry-leading print throw distance with the lowest maintenance requirements on the market.


Industry-Leading Barcode Decode-ability & Print Throw Distance

Three unique features combine to allow the IJ4000 to provide best-in-the-market print consistency on challenging packaging lines where boxes are rarely perfectly uniform.


First, precision print placement is ensured by a unique roller retractor and a digital level sensor accelerometer. The roller retractor provides a consistent gap between the print surface and print engine. A green LED light on the digital level accelerometer indicates when the print engines are perfectly aligned and perpendicular with the packaging material to be printed- regardless of floor variations. This ensures high-quality print and optimal readability for bar codes.


Secondly, the print engines of the IJ4000 provide throw distance of ½ inch for alphanumerics and an industry-leading ¼ inch for barcodes. This is double the 1/8 inch throw distance currently provided in the market for readable barcodes. In addition to ensuring high-quality print, the increased throw distance also reduces the impact of corrugate dust, glue and contaminants resulting in reduced maintenance needs.


Finally the unique design of the print engine ensures print is up to 15% darker than the last generation offering.


Combined these features allow the IJ4000 to offer a 35% improvement on barcode decode-ability compared to competing systems available in the market.


Industry-Leading Flexibility & Ease of Use
The IJ4000 was carefully designed based on customer feedback for optimal ease of use. The system features a unique HMI (Human Machine Interface) wherein the print engine, encoder and photocell connections run directly and cleanly to the connection hub. This allows the HMI to be moved to a remote location for greater ease of use. The HMI can be as far away as 100 meters when connected via Ethernet and an unlimited distance when connected through a Network.


The system offers a great deal of flexibility with both on-floor and in-office editing capabilities. The intuitive interface provides the option of use with a personal PC, eliminating the need for a separate controller and reducing cost by as much as 15%.


The integrated 10.2 inch touch screen controller interface eliminates the need for a separate keyboard, thereby reducing the system footprint. The system print head is also smaller in all three dimensions and further flexibility is provided by a dovetail track on both side of the print engines for ease of mounting on either side of the conveyer.


While many printing technologies advertise that they are ‘Unicode-ready’ they often mean that language characters are used as locked images. This is not the same as true real-time, variable print Unicode capabilities.  Diagraph’s IJ4000 printers were specially designed to provide real-time printing in 11 languages.


Lowest Maintenance Requirements in the Market

The IJ4000 was carefully designed to provide the lowest maintenance requirements of any similar system in the market today.


The printer features a unique single point ink supply that can feed as many as four different print engines. This greatly reduces downtime and simplifies the fluid refill process as it is not necessary to monitor and maintain individual ink supplies.


The system´s unique digital level accelerometer has a sensor which indicates if the print engine has tilted plus or minus 1.5 degrees both for ease of installation and to assure the print gap between print head and carton is consistent along the entire print image.


A new auto-channel purge allows all 256 printhead channels to be quickly checked by a simple push of a button on the print head right on the packaging line. Maintenance is further simplified by hard-mounted, easily accessible filters and a centralized connection point that simplifies and reduces cabling requirements.

Taken together, these features allow the IJ4000 to provide as much as 30% less downtime than alternative technologies.


Industry-Leading Print Engine Durability 

Featuring unique-in-the-industry stainless steel construction, and patented repairable (rather than disposable) design, shock resistance capability and automatic maintenance modules, the Trident print engines in the IJ4000 provide industry-leading durability. Whereas traditional print engines might need to be replaced as often as every few months, Trident technology can last as long as 10 years or 300 billion firings. This allows the IJ4000 to provide industry-leading durability with projected lifespan being as much as 5 times longer than competitive technologies.

“The IJ4000 is the result of over 5 years of intensive research into user needs,” said Steve Liker, LCIJ Product Manager at Diagraph. “It was thoughtfully designed with a number of unique-in-the-market features to provide customers with significant new performance benefits at the same price point as our last generation technology. We are proud to offer significantly more value at the same competitive price.”

The new print engines are reverse compatible to older IJ3000 systems for existing customers and are available with two inch print height.  Technology featuring market-leading four inch print height is anticipated to launch in 2016 and will be forward compatible with the IJ4000 system.
