Case Codes

Case codes, logos, text, and product identification are essential for proper delivery and tracking. Companies that produce dog food, shampoo, stationery supplies, and hardware items want their goods labeled for many reasons, not the least of which is free advertising. Scanned barcodes aid in relaying information back to the manufacturer about destinations and dealers.

Mass merchandise is shipped in cases of multiple units, the exact number depending on the size of each unit. Cases of canned dog food would have more units than cases of three-liter wine bottles, and cases of canned tuna would have more units than bottled water. The substrate remains the same, however--corrugated cardboard, a porous surface that requires special inkjet printers and inks.

Printing Case Codes

Inkjet printing systems can print information on the side, top, or bottom of a box. Printheads come in several configurations, and have a range of characters and inks appropriate to the specifications of the particular business. As speed is important in assembly line operations, inkjet systems that print case codes are not only fast, but almost maintenance-free. If a part needs replacing, modular construction permits the exchange in a few minutes.

No-clog ink contributes to this smooth operation and allows ink to remain in the printheads for several weeks without flushing or cleaning. Even when a business uses coated, corrugated containers--which precludes the use of water-based inks--solvent-based inks can do the job. In fact, some inkjet printers can handle both porous and non-porous printing for even greater savings in handling case codes.
