Polaris PQ-512 AAA Family — Which Drop Size Do You Need?
| Model | Drop Range | Max Resolution | Best For |
|---|---|---|---|
| PQ-512/15 AAA | 15 – 80 pl | 800 dpi | Fine-detail, high-resolution wide-format |
| PQ-512/35 AAA | 35 – 80 pl | 800 dpi | Balanced speed and quality, UV and solvent |
| PQ-512/85 AAA (this listing) | 80 – 150 pl | 400 dpi | Heavy-coverage, high-throughput industrial UV and solvent |
The PQ-512/85 is the large-drop variant — it sacrifices resolution (400 dpi vs 800 dpi) for dramatically higher ink laydown and throughput. This makes it ideal for heavy-coverage applications where dense, rapid UV or solvent deposition is more important than fine detail. Contact our team to confirm which PQ-512 drop size your OEM system specifies before ordering.
VersaDrop Technology on the Polaris PQ-512/85
VersaDrop enables the PQ-512/85 to jet adjustable drop sizes from 80 up to 150 pl in binary mode — allowing ink density to be tuned without changing the head or operating frequency. At 50 kHz maximum frequency, the PQ-512/85 delivers the highest jetting rate in the Polaris PQ-512 family, making it suited to continuous high-throughput industrial production where maximum coverage speed is the priority.
Field-Repairable Design
The Polaris PQ-512 AAA family uses a modular field-repairable architecture — components can be replaced on-site without special tools. Combined with built-in heaters and temperature sensors for precise viscosity control, this reduces maintenance downtime compared to sealed non-repairable heads. The design builds directly on the proven reliability of the earlier Spectra Nova and Galaxy printhead platforms.
Compatible Systems
The Polaris PQ-512/85 AAA is an OEM-integration industrial head used across UV, solvent, and aqueous wide-format production systems. It does not have a fixed compatible printer model list — specification is determined at the OEM system level. Contact our team with your printer make, model, and current printhead part number to confirm PQ-512/85 compatibility before ordering.
Warranty Notice
Due to the sensitive nature of industrial printhead components, we cannot accept returns, exchanges, or refunds once the printhead has been installed. All sales are final. Contact our team to confirm compatibility before ordering.

Frequently Asked Questions
What is the difference between PQ-512/85, PQ-512/35, and PQ-512/15?
All three are 512-nozzle Polaris Q-Class heads with VersaDrop binary jetting and identical field-repairable design. The difference is drop size and resolution: PQ-512/15 (15–80 pl, 800 dpi) for fine detail; PQ-512/35 (35–80 pl, 800 dpi) for balanced performance; PQ-512/85 (80–150 pl, 400 dpi) for maximum ink laydown and throughput. The drop size variant your OEM system uses is determined at the factory and cannot be changed. Always confirm which variant your printer specifies before ordering.
Is the PQ-512/85 field-repairable?
Yes — all Polaris PQ-512 AAA heads use a modular field-repairable design that allows component replacement on-site without special tools. This is a key advantage over sealed industrial heads and reduces maintenance cost significantly in high-volume production environments.
What does "VersaDrop" mean on the PQ-512/85?
VersaDrop allows the head to produce adjustable drop sizes within the 80–150 pl range in binary jetting mode — ink density can be varied without changing the head or jetting frequency. At 50 kHz maximum frequency, the PQ-512/85 delivers the highest throughput in the PQ-512 family, making it suited to applications prioritising maximum coverage speed over fine resolution.
Do you ship Spectra Polaris PQ-512/85 AAA printheads to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Our Miami location is ideal for Latin American industrial UV and solvent print shops using freight forwarders in the Doral area.
