Large Character Inkjet

A large character inkjet printer prints larger text and, on suitable high-resolution models, barcodes and graphics directly onto outer packaging. It is commonly used to identify corrugated cases as they move along a packing line. Rather than marking each individual bottle or pouch, the printer identifies the box holding those products. The code might show the product name, batch, packing date or information needed by a warehouse. LETO’s range includes basic valve-jet case coders and high-resolution carton printers, so the starting point is what the finished box needs to communicate.

Large character inkjet printers can put product identification and variable production information directly on shipping cartons. Depending on the model, this can include product names, batch numbers, dates, counts, barcodes and logos. Keep the message relevant to the people receiving and handling the case: a warehouse may need a scannable product code, while production staff may need a clear batch and packing date. Decide which information stays the same and which changes between runs. Then check that the chosen printer can produce the full message within the available carton panel.

Choose the Unicorn or Unicorn II for basic alphanumeric case coding, and consider the Videojet 2380 when the carton needs detailed text, barcodes or logos. The Unicorn and Unicorn II are compact, low-resolution valve-jet printers: the Unicorn prints one line, while the Unicorn II supports one or two lines. The Videojet 2380 is a high-resolution case printer. A simple batch or date message does not need the same print capability as a carton barcode. Send LETO the actual message layout before choosing a model.

High-resolution case printing can let you use a common carton design and add product-specific information during packing. For businesses managing several products in the same box size, this can reduce the number of preprinted carton versions held in storage. The Videojet 2380 is designed to print text, barcodes and logos on generic cases. The practical benefit depends on how much of your carton artwork can be printed within its available print area. Compare the proposed layout with your existing box, including branding, handling instructions and customer requirements, before changing carton orders.

Direct carton printing suits applications where the box surface provides a suitable background for the required code. Print-and-apply labelling is worth considering when a label provides a more suitable print surface or when the customer specifies a label. Brown corrugate, coloured artwork and coatings can all affect the result. Compare the two options using the same carton, message and receiving requirements, rather than equipment price alone. LETO offers both corrugated box printing solutions and print-and-apply labellers. A sample comparison can show which approach gives the clearer, more practical identification for your cases.

A suitable high-resolution large character inkjet printer can print carton barcodes directly onto corrugated packaging. The Videojet 2380 supports linear and 2D barcode formats, including Code 128, DataMatrix and QR codes. Barcode capability alone does not establish that a finished case meets your customer’s requirements. Check the required format, encoded data, size, clear space around the code and print position. Test the actual carton at the intended production speed, and request barcode verification where a specified quality grade is required. A successful scan is useful, but it does not replace verification against a required grade.

Case coding ink must match both the printer and the carton surface. Uncoated corrugate absorbs ink differently from coated board, so an ink that works on one box may not produce the same result on another. LETO lists high-resolution inks for porous substrates and low-resolution formulations for different porous and non-porous applications. That does not mean every ink works in every printer. Share the board specification and send finished cartons, including printed or coated areas, for testing. LETO’s case coding inks page provides a starting point for selecting compatible supplies.

A suitable carton printing system can mark more than one side of a box using multiple printheads. The Videojet 2380 supports up to four printheads from one touchscreen, allowing different print positions within an appropriate line setup. The number of heads needed depends on the carton faces to be marked and the message layout. Before specifying the system, check how boxes travel past the printer, whether their position varies and whether guides or mounting changes are needed. Printhead access also matters: operators need room to inspect the printed result and carry out routine care.

The cost of a large character inkjet system depends on the message, printer model, printhead arrangement and work needed to fit it to the packing line. A basic date coder and a system printing detailed codes on several carton faces are different projects. For a useful quote, provide carton sizes, board finish, a sample message, production speed and the sides that need printing. Compare running costs using your expected ink coverage and production volume, alongside maintenance and operator time. Contact LETO with those details to request an application-specific equipment quote.

Clear, correct carton codes depend on both printer care and a consistent job-change process. Check the selected message and the first printed case at every changeover, including the batch, date and barcode data. Follow the model’s instructions for cleaning and ink replacement. The Videojet 2380 includes automated nozzle cleaning and a touchscreen for message editing and job selection; these features support production but do not remove the need to inspect the output. If print quality changes, check the carton surface, box position and printhead condition. LETO’s technical training can help operators establish a repeatable routine.

LETO can arrange sample marking so you can assess the proposed carton code before choosing equipment. Send representative finished cartons and the message you want printed, including any barcode data. Include different board finishes or colours if they are used in production. LETO advises that sample testing typically takes four to six weeks, depending on complexity; confirm the timing for your request. Marked samples are returned with a report covering results and recommendations. Use the LETO Sample Lab to discuss the test, and ask which checks will address your carton, handling conditions and customer requirements.

LETO Technology supplies large character inkjet printers and provides service and support across Australia from its base in Wacol, Brisbane. Its range includes the Unicorn, Unicorn II and Videojet 2380 for different case coding requirements. When discussing a new system, include your site location, carton examples and packing-line details so the equipment and support arrangements can be scoped together. For an existing printer, have the model and a sample of the print problem ready. Explore LETO’s service packages or call 1300 02 02 04 to discuss your application and ongoing support needs.
