Konica KM1024aLHG-RC printhead

The Konica KM1024aLHG-RC printhead is a high-productivity, compact inkjet printhead using independent channel, on-demand piezo technology with 1024 nozzles arranged in 4 rows of 256 nozzles each. It has a print width of approximately 72 mm and is designed with dual flow nozzle level recirculation, making it suitable for solvent, UV, oil, and water-based inks, and ideal for high laydown applications such as ceramics and opaque white printing.

What is KM1024aLHG-RC?

A compact, dual-flow recirculating, analogue-driven Konica Minolta printhead designed for high productivity in narrow footprints, suitable for fast drop-on-demand printing with recirculating inks. It supports multiple ink types and is built for robust industrial use..

Key specifications at a glance

• Nozzle count: 1024 (distributed across multiple channels/lines) for high-resolution coverage.
• Drop size: multiple options available; commonly around 25 picoliters in the “aLHG-RC” variant, enabling good balance of speed and print quality.
• Print width: designed for compact footprints with significant width efficiency; compatible with standard 72 mm wide applications in KM1024 family.
• Drive technology: dual-flow recirculation with analogue drive, enabling stable jetting and easier integration into recirculating ink systems.
• Ink compatibility: supports solvent, UV, oil, and water-based inks depending on variant; verify exact compatibility with your chemistry.

Why choose KM1024aLHG-RC?

• High productivity in a small form factor due to compact recirculating design and rapid firing capability, ideal for ceramic, opaque white, and other demanding laydown tasks in narrow machines.
• Simple integration with robust reliability; good fluid compatibility reduces integration risk.
• Frequent availability of different drop-size options (e.g., 25 pl) to tailor gradient and color accuracy to your print job.
• Typical applications
• High-speed industrial printing where multiple heads are mounted in close proximity to minimize transport length and registration errors. Ceramic coatings, white ink laydown, and other demanding graphic/industrial tasks benefit from the KM1024 family.

Pros and cons to consider

• Pros: compact footprint, high nozzle density, suitable for high-productivity systems, compatible with recirculating ink systems, multiple drop sizes for tonal control.
• Cons: as a specialized head, it requires compatible drive electronics and ink recirculation hardware; ensure your system supports dual-flow recirculation and proper fluid chemistry.

What to confirm before purchase

• Ink compatibility: confirm exact ink chemistries (solvent, UV, oil, water-based) supported by the specific KM1024aLHG-RC variant you’re evaluating.
• Electrical/mechanical interface: verify mounting pitch, electrical drive requirements, and connection standards for your printer chassis.
• Availability and warranty: check current stock, lead times, and whether a manufacturer or authorized partner warranty applies to your region.
• Replacement cost and life: understand nozzle life, typical maintenance intervals, and cost of replacement heads for budgeting.

Quick decision checklist

• Do you need high productivity with a compact head in a recirculating system? If yes, KM1024aLHG-RC is a strong candidate.
• Is your ink system compatible (recirculating, correct viscosity, and chemistry)? If yes, proceed with engineering evaluation.
• Can your control electronics handle analogue drive and dual-flow recirculation without extensive redesign? If yes, speed up integration.

If you’re upgrading a ceramic-print line that previously used KM512 heads, the KM1024aLHG-RC can offer double the width per head and eight-level grayscale (depending on variant), enabling faster throughput with comparable tonal control, provided your ink and driver electronics are matched.
