Case Coding on Corrugate Trays: Improve Tray Visibility

Printing on corrugate trays varies widely based on composition, surface texture, and rigidity. Their porous nature causes ink to absorb unpredictably, which can lead to blurred or faded codes, especially in high-humidity environments. Adding vibration from corrugated conveyor printing makes maintaining code clarity even harder.

Tray movement introduces inconsistency. Even slight vibrations or vertical fluctuations can cause code placement to be skewed. The MSU continuously monitors print height, detects target vibration, and tracks line speed to maintain stable print quality. If abnormal motion is detected, like a jolt or collision, the system alerts the operator before quality is compromised. That kind of real-time feedback helps avoid downtime and keeps code legible.

TIJ printers offer a lower upfront investment, but rely on replaceable cartridges that can drive up long-term costs. For high-volume operations, the cost of frequent swaps quickly adds up. High-resolution PIJ systems operate on bulk ink, using fewer consumables and resulting in a lower cost per mark. Combined with KEYENCE self-cleaning modules and long-lifespan components, this creates a low-maintenance, cost-effective platform designed for sustained industrial use.
