Inkjet & CIJ (LCP) Labelling Overview
Kelgray supplies and supports continuous inkjet (CIJ) and large character printing (LCP) for reliable coding on products, containers and outer cases. We select the right inks, printheads and integration approach for your line, then maintain performance so codes remain clear, durable and consistently readable at speed, in everyday factory conditions.
Service information
We provide inkjet coding as an engineered service: we review your substrate, line speed, environment and available space, then match the right CIJ and/or LCP configuration for dependable results.
CIJ gives non-contact, high-speed coding on diverse shapes and materials; LCP focuses on bold, legible marking for secondary packaging like cases and cartons. We design mounts, guards and triggers, integrate with sensors, encoders and PLC I/O, and commission on your line to confirm adhesion, drying time and code readability.
Reliability is protected through correct ink selection, viscosity/temperature considerations, and straightforward operator routines. We offer training, documented set-ups, preventative maintenance and responsive support, plus managed ink/solvent supply to keep performance consistent.
Printing direct-to-pack can reduce label usage and avoid pre-print inventory risk when data changes. We also validate print placement and contrast for reliable scanning. Our ISO 9001 processes and SafeContractor approval support quality-controlled installs and service.
Why this matters and why we’re the right partner :
Maintain Throughput:
Keep throughput high. We configure CIJ and LCP systems for stable performance at line speed, with correct triggers, protective mounting and clear routines that reduce stoppages and downtime every shift.
Right Ink Chemistry:
Get the right ink chemistry. We match inks to substrate, handling and drying time, helping codes resist smudging and abrasion while remaining consistently legible, so you protect quality and traceability.
Reliable Supplies:
Avoid surprises with supplies. We specify inks, make-up fluids and service items, then support managed replenishment so your prints stay consistent between deliveries and your engineers spend less time firefighting.
System Integration:
Integrate cleanly with existing lines. We connect to sensors, encoders and control systems, apply consistent message governance, and commission to your standards delivering a repeatable, scalable approach across multiple lines.
Specialist Coding & Marking Scanners Options
Other options within Coding & Marking: For high-resolution variable printing onto flexible films before pack forming, our TTO systems deliver crisp codes and excellent aesthetics, ideal for wrappers, pouches and sachets.

Our Frequently Asked Questions
Here are all of the answers to your most common questions around Inkjet / CIJ (LCP):
A: CIJ (continuous inkjet) prints smaller characters at high speed and is ideal for coding directly onto individual products or primary packs, including curved or irregular shapes. LCP prints larger, bolder messages often on cases and cartons so information stays easy to read through distribution.
A: Inkjet coding is non-contact and can be configured for many common production materials, including plastics, glass, metals, cartons and corrugated cases. The key is matching the printer type and ink to your substrate, line speed and operating environment.
A: We assess adhesion needs, drying time, contrast, handling conditions and any wash-down or abrasion risk. From there, we specify a suitable ink chemistry and maintenance routine so codes stay legible and reliable without creating unnecessary operator workload.
A: They can, provided the symbol is sized and placed correctly and the print quality is stable. We help you design the message, validate contrast and quiet zones, and confirm scan performance so your barcodes move through the supply chain smoothly.
A: We integrate using appropriate mounting and guarding, then connect print triggers to sensors and, where needed, encoders for timing. For automated data, we can link coding to your control systems so batch, date or serial information is governed and repeatable.
A: Maintenance varies by technology and environment, but reliability improves with simple routines and planned servicing. We set clear operator checks, provide training, and offer preventative maintenance and responsive support so issues are resolved before they become stoppages.
A: We standardise message templates, permissions and set-up documentation, then align consumable specifications so the output is repeatable. This reduces variation between shifts, supports faster changeovers, and helps new lines ramp up quickly.
