Product Overview: The Spectra Polaris PQ-512/85 AAA is a heavy-duty industrial inkjet printhead engineered for high-volume, wide-format outdoor printing. Featuring a large 85 picoliter (pl) native drop size, this printhead is designed to deliver maximum ink coverage and high density over massive surfaces. It is the premier industry choice for high-speed grand format billboards, mesh banners, and heavy textile printing where rapid turnaround and deep color saturation are critical.

Technical Specifications:

• Total Active Nozzles: 512 independent channels
• Native Drop Size: 85 pL (Configurable up to 150 pL for maximum ink laydown)
• Maximum Hardware Resolution: 400 dpi
• Firing Frequency: Up to 15-20 kHz (Optimized for continuous, high-volume production)
• Ink Compatibility: Highly resilient with aggressive Solvent, Eco-Solvent, and heavy-pigment industrial inks
• Internal Architecture: Built on Fujifilm Dimatix’s durable Q-Class platform with an all-metal nozzle plate, offering unmatched resistance to mechanical wear

Primary Applications:

• Grand-format outdoor billboards, building wraps, and giant vinyl banners
• Mesh banners, fence wraps, and high-porosity outdoor materials
• High-volume solvent printing requiring thick ink laydown and rapid delivery

Key Advantages:

• Max Ink Coverage: The 85pl large drop size delivers rich color saturation and high media coverage in fewer passes, perfect for massive outdoor displays.
• Clog Resistance: Larger nozzle orifices drastically reduce clogging and drying risks, making it highly tolerant of aggressive inks and dusty environments.
• Industrial Durability: Built with a rugged metal housing and robust nozzle plate, it easily withstands frequent wiping and high mechanical stress.
• Low Upkeep Costs: Stable fluid dynamics and thermal control minimize daily maintenance, maximizing production uptime.
