Replace pre-printed boxes and manual marking with large character inkjet printing for outer cases, transit cartons, sacks and end-of-line packaging.
Before buying a coder, confirm the pack surface, speed and code requirement. The same date code can need a different machine depending on whether it is printed onto a curved bottle, carton, flexible film or outer case.
| Common uses | Outer case coding, carton batch marking, destination print, product ID |
|---|---|
| Typical products | Cardboard cases, trays, sacks, timber, drums and transit packs |
| Line integration | Side mounted print heads, product sensors, encoders and conveyor guides |
| Selection data needed | Print height, number of lines, carton surface, line speed and required data source |
Print expiry dates, batch numbers and traceability codes onto plastic bottles, glass bottles, jars, tins and small containers.

Yes. Porous carton coding is a common use, with ink selection and print height matched to the packaging.
Many systems can receive variable data from a controller, scanner or database, depending on the model and integration scope.
Direct-to-case printing can remove pre-printed carton variants or labels, but the result depends on the box surface, print height, viewing distance and barcode-quality requirement.
Absorbent board often accepts water- or oil-based inks, but recycled fibre, dust, coatings and colour variation can reduce edge definition and contrast. Test every case grade that will be approved for production.
Coated board, plastic totes and glossy cartons may need a different ink system and longer drying or protected handling. Do not assume an ink proven on brown corrugated will work on a coated white case.
Provide the complete case mark, including text, symbols, date, lot, product code and barcode. Confirm the viewing distance and whether one or more printheads are needed to build the required height.
| Decision | Direct large-character inkjet | Print-and-apply label |
|---|---|---|
| Variable text | Efficient for changing text and simple graphics printed directly on the case. | Useful when detailed layouts, compliance labels or multiple media fields are required. |
| Surface | Best where the ink is proven on the actual case and presentation is controlled. | Label stock creates a consistent printed surface but adhesion to the case must be checked. |
| Barcode control | Can be suitable, subject to print resolution, contrast and case quality. | Often preferred for demanding logistics barcode grades and complex labels. |
| Consumables | Ink supply and cleaning routine. | Labels, ribbon where used, printhead wear and applicator maintenance. |
| Changeover | Message change without changing physical packaging artwork. | Message and label format change, with media replenishment. |
Cases must pass the printhead with a stable face and controlled gap. Confirm conveyor speed, case spacing, side guides, flap condition, vibration and the risk of skew. An encoder may be required where speed varies. If data changes case by case, define the source, record queue and behaviour when data is missing.
For multiple case sizes, record the printhead adjustment method and whether recipes, handwheels or automatic positioning are required.
Agree whether the requirement is a scanner read, process monitoring or formal verification. For formal grading, the verifier, lighting and applicable standard must be defined. Case colour, fibre, corrugation and ink spread can affect symbol contrast and modulation.
Include a reject or line-stop strategy where a missing or unreadable code creates a traceability risk.
It can where the printhead or case guide can be adjusted safely and repeatably. The adjustment range, datum and changeover method should be defined in the quotation.
Supply every board grade, colour and coating that represents normal production, including recycled or printed cases. Send the complete mark and the intended code location.
Not always. Labels may remain preferable for complex logistics content, strict barcode grades, customer-mandated formats or surfaces that do not accept direct ink reliably.
Use the actual print area, coverage, number of sides, cases per shift and cleaning routine. Compare those assumptions with label and ribbon use if print-and-apply is the alternative.
Send case samples, the full mark and conveyor details for a direct-print versus label review.
