Using Large Character Marking for Traceable Codes and Images | InkJet, Inc.

When most people think about traceable product markings, they likely first imagine small character codes. This association makes sense. After all, small character codes like expiration dates, batch numbers, barcodes, and data matrices are located on nearly all mass distributed products, including pre-packaged food, beverages, pharmaceuticals, and cleaning products.

Although it's hard to walk into a store and not see small character markings, large character codes are also an important part of fostering product traceability. For example, large-scale barcodes and logos are often placed on cardboard shipping cartons and other forms of secondary packaging to ensure that the packages can successfully make their way across the supply chain. 

With the help of these large character markings, companies can better meet distributor guidelines, maintain tracking of their goods, and help maximize distribution efficiency. Conversely, if these codes and images are not applied properly, it can lead to many supply chain issues, including delays, rerouted shipments, and lost inventory. 

For those new to the world of large character marking, here’s how you can successfully create vibrant images and long-lasting machine-readable codes.

What Exactly Is Large Character Marking?

Before exploring the different types of large character marking systems on the market today, it’s important to understand what exactly we mean when we use the term “large character marking”. 

Large character marking is an umbrella term that refers to creating codes, text, and images that are around an inch tall or larger. Large character marking devices are most commonly used to mark secondary packaging (and especially cardboard shipping cartons) with traceable information and brand-associated images/logos. 

By using a large character marking system to perform secondary packaging applications, companies can eliminate the need for adhesive labels—a move that helps to both lower material costs and enhance operational efficiency

Large character marking can be performed by a few different technologies, with the most common being:

  • High-resolution, large character case coders, which use piezoelectric printheads and inkjet systems to create DPI-rich images and codes on porous substrates. Depending on model and printhead specifics, case coders can create markings anywhere from 1” to 4” high.
  • Thermal inkjet printers, which use thermal dynamics to launch liquid ink onto porous and non-porous materials. Although not all TIJ printers are capable of large character marking, many models are built with 1” printheads to create larger codes and text. 

Additionally, many TIJ models are built with stitching capabilities, meaning that multiple printers can be used simultaneously to create one large image (i.e., four stitched 1” printheads can be used to create one 4” image).

  • Thermal transfer overprinters (TTO), which melt ink-covered wax ribbons to place high-DPI markings onto porous and non-porous surfaces. As with case coders, TTO code size capabilities are influenced by printer model and printhead specifics, with the largest TTO codes reaching above 4”.
