Konica Minolta

KONICA MINOLTA is a globally renowned imaging technology company from Japan. Its Inkjet Division has long been dedicated to the research and innovation of industrial inkjet printing technologies. The Konica series printheads are widely recognized for their advantages in grayscale printing, high jetting speed, and strong stability, making them highly popular in the global market.

Konica 512i LNB

The Konica Minolta 512i LNB printhead is designed for high-speed, high-definition output. It adopts a 512-nozzle structure and supports a native resolution of 360 dpi, delivering a firing frequency of up to 30 kHz. It is suitable for printing environments that require continuous long-term operation and high-volume output, such as wide-format advertising and industrial inkjet production.

Core Advantages

1. High Frequency & High Resolution

The firing frequency reaches up to 30 kHz, with a native physical resolution of 360 dpi. It supports grayscale printing, meeting the dual requirements of high-clarity imaging and high-speed output.

2. Multi-Drop Grayscale Control

It supports 14–27 pl drop sizes, making it suitable for achieving both sharp text output and smooth image gradients, providing a balanced performance between print quality and ink efficiency.

3. Wide Material Compatibility

Compatible with both solvent-based and oil-based inks, it enables high-quality printing on a wide range of substrates, including frontlit/backlit banner media, self-adhesive vinyl, soft film, label paper, PVC, and more.

4. Compact & Robust Design

With a compact printhead design, it is well-suited for multi-head printing platforms and scanning systems. Its internal structure is stable and reliable, meeting the demands of continuous industrial operation.

Technical Specs

Main Drawbacks

Higher price: As a high-frequency printhead, the cost of procurement and maintenance is relatively high.

High ink quality requirements: Requires well-filtered and stable ink to avoid nozzle clogging.

Not suitable for ultra-small droplet printing: Minimum droplet size is 14 pl, limiting ultra-fine art printing.

Requires professional installation and maintenance: High firing frequency and precise ink supply demand experienced technicians.

Application Scenarios

1. Outdoor Advertising & Large-Format Printing

Frontlit/backlit banners

Vehicle wraps, vinyl, outdoor posters

Suitable for 2-head, 4-head, 6-head or more multi-head high-speed printing systems

2. Indoor High-Definition Printing

PP paper, poster paper, photo media

Lightbox film, exhibition materials

Ideal for multi-layer color applications that do not require ultra-small droplets

3. Packaging & Label Printing

Soft packaging film, labels, stickers

PVC shrink film, heat-transfer film

Industrial-grade packaging applications

4. Industrial Decorative Printing

Leather, aluminum plate, PVC board, glass fiber fabric

Building materials, custom décor boards

Suitable for durable and high-strength printing needs

5. Electronic & Thin-Film Material Printing

PET film, PP sheet, PCB substrates

Flexible electronics, protective films

Ideal for high-precision industrial printing environments

Usage Recommendations

Use original solvent/UV-compatible ink to avoid nozzle clogging from contaminated or unstable ink.

Ensure clean ink interfaces before installation and maintain stable ink pressure/negative pressure during operation.

Use recommended waveform parameters and adjust under guidance from engineers.

Perform nozzle checks regularly to avoid missing lines caused by ink starvation.

When using for the first time, confirm waveform debugging is completed for optimal performance.
