Printhead

SEIKO (SII)

SEIKO Group originates from Japan and is a world-renowned precision manufacturing enterprise. Its subsidiary, SII (Seiko Instruments Inc.), has been deeply involved in the inkjet printing industry for many years. The company has launched multiple industrial-grade printheads with piezoelectric technology, widely recognized for their high reliability, long lifespan, and strong ink compatibility. These printheads are essential components in industries such as advertising, labeling, and packaging.

SEIKO 508GS

The SEIKO 508GS is a piezoelectric industrial printhead featuring 4-level greyscale control and 508 nozzles. It supports wide-format printing, stable ink ejection, and broad ink compatibility. Compatible with solvent-based, UV, oil-based, and water-based inks, it is widely used in fields ranging from outdoor advertising to industrial coding.

Technical Specs

Core Advantages

1. Strong Ink Compatibility
Supports water-based, oil-based, solvent-based, and UV inks. One head supports multiple ink types, ideal for various production scenarios.

2. Greyscale Printing for Fine Details
Offers 4-level greyscale control with ink droplets as small as 12pL, ensuring smooth gradients and detailed output, perfect for text-and-graphic combined ads.

3. Internal Recirculation System for Anti-Clogging
The printhead includes an internal ink recirculation system that helps prevent ink sedimentation and ensures long-term stable output.

4. High Jetting Frequency, Reliable Productivity
Maximum jetting frequency reaches 28kHz, suitable for long-time, high-volume production, especially advantageous in labeling and packaging industries.

5. Compact and Durable Structure
Lightweight design (under 300g), suitable for multi-head arrangements and wide-format equipment.

Main Drawbacks

1. Limited Greyscale Levels
Compared to Ricoh G6-level printheads, its greyscale precision is slightly lower, supporting only 4 levels of greyscale control.

2. Relatively Low Resolution
With a native resolution of 180 dpi, it meets most advertising application needs but falls short for ultra-high-definition output requirements.

3. Requires High-Quality Ink and Mainboard
To ensure stable performance, it’s recommended to pair the printhead with high-quality ink and compatible mainboards to avoid voltage instability or control errors.

Application Scenarios

1. Outdoor Advertising & Photo Printing: For lightboxes, vehicle wraps, PP sheets, and advertising boards.

2. Industrial Labeling & Packaging: For tile labels, plastic packaging, paper tags, etc.

3. Pharmaceutical & Cosmetics Packaging: Supports barcodes, QR codes, logos, and expiration date printing.

4. Textile Wash Labels & Tags: For garment labels, care labels, washing instruction tags, etc.

Usage Tips

1. Use high-end solvent/UV ink brands to avoid impurities that may reduce printhead lifespan.

2. Perform regular printhead cleaning and moisturizing for long-term operation.

3. Check ink pressure during startup to ensure the internal circulation system is working properly.

4. Avoid frequent ink type switching. If switching is necessary, thoroughly clean the ink path and recalibrate.
