The Xaar 2002 Advanced GS12 is an industrial inkjet printhead designed for high-resolution, single-pass printing with excellent uniformity and reliability, especially in applications like ceramics, textiles, packaging, and functional coatings.
Key specifications
- Resolution: 720 nozzles per inch (720 npi)
- Nozzles: 2,000 nozzles across a 70 mm wide print zone
- Drop sizes: 6 pL to 400 pL using XaarDot greyscale technology; GS12 indicates a 12‑level greyscale mode
- Firing frequency: Up to 36 kHz (some driver electronics support up to 48 kHz)
- Viscosity: Can jet fluids up to ~100 cP
- Laydown: Supports both standard and “High Laydown” / “Ultra High Laydown” modes, with reported coverage up to ~240 g/m² in special configurations
- Dual-channel architecture: Two independently driven channels in one head, allowing:
- Two different fluids/colours in one bar, or
- Same fluid in both channels for 720 dpi single‑colour printing
Core technologies
- TF Technology: Ink recirculation inside the head for fast prime-up, reliable jetting, and reduced nozzle blockages
- XaarDot / Greyscale: Multiple drop sizes and greyscale levels (e.g., 12 levels for GS12) to optimise tonal range, coverage, and image quality
- AcuChp & TAM: Built‑in calibration data to ensure uniformity across the head width and between heads, reducing colour banding and tone variation
- Sure Flow: Ultrasonic self-cleaning to clear/prevent nozzle blockages without removing the head
- XaarGuard: Nozzle protection features to maximise uptime and head life
Typical applications
The Xaar 2002 Advanced GS12 is widely used in:
- Ceramic tile printing (e.g., System Ceramics’ Creaseven machines use 60+ Xaar 2002 GS12 heads for multi‑fluid, high‑resolution patterns)
- Textile and fashion printing, where high laydown and colour gamut are important
- Packaging and decorative printing, including varnish, textures, and special effects
- Functional printing (coatings, adhesives, conductive materials) where higher viscosity fluids are required
Installation and integration
- Designed for relatively fast “plug and print” integration with plug‑in connectors and simplified setup
- Compatible with Xaar’s XPM and third‑party drive electronics (e.g., GIS PHC‑XR‑2002 card) that support Xaar 2002 Plus/Premium/Advanced at GS6 and GS12
- Often sold as a standalone printhead with expected handling by trained technicians, as it is a high‑precision component
