VersaDrop™ Technology — What It Means for Your Production
VersaDrop™ is Fujifilm Dimatix's variable drop technology built into the Polaris PQ-512 platform. The native 35pl drop size can be scaled up to 80pl using VersaDrop, enabling the same head to deliver finer detail at smaller drops in highlight areas and larger drops for faster solid coverage — without switching heads. Combined with resolution up to 800 dpi and fire frequencies exceeding 50 kHz, the PQ-512/35 delivers both production speed and image quality flexibility that fixed drop-size heads cannot match.
Field-Repairable Design — A Polaris Advantage
Each Polaris PQ-512/35 consists of two 256-channel modules. If a module fails, it can be replaced independently in the field — without special tools, without recalibration, and without replacing the entire head assembly. The integral mounting bezel with precision registration points ensures drop-in alignment after module replacement. For high-production environments, this significantly reduces printhead replacement costs and downtime compared to non-repairable industrial heads.

Frequently Asked Questions
What is the difference between Polaris PQ-512/35 and PQ-512/15?
Both have 512 channels and VersaDrop technology but at different native drop sizes. The PQ-512/35 jets 35pl natively (up to 80pl with VersaDrop) — suited for standard to high-viscosity ink systems and production UV/solvent printing. The PQ-512/15 jets 15pl natively (up to 30pl with VersaDrop) — suited for fine-detail applications and mid-viscosity inks. Contact our team to confirm the correct variant for your printer.
What does field-repairable mean for the PQ-512/35?
Each Polaris PQ-512/35 consists of two 256-channel modules. If one module fails, it can be replaced independently in the field — no special tools, no recalibration required. The integral mounting bezel ensures drop-in alignment after replacement. This significantly reduces total cost of ownership compared to non-repairable industrial heads.
What inks are compatible with the PQ-512/35 AAA?
The PQ-512/35 is compatible with UV-curable inks, aggressive organic solvent inks, and aqueous inks — plus associated maintenance fluids. Built-in heaters allow ink temperature management up to 60°C for consistent viscosity across production runs. Always verify ink compatibility with your printer manufacturer's specifications.
What is VersaDrop™ on the Polaris PQ-512/35?
VersaDrop™ is Spectra's variable drop technology that allows the native 35pl drop to be scaled up to 80pl. This enables the same head to produce finer detail at smaller drops and faster fill at larger drops within the same print pass — at resolutions up to 800 dpi. It is a capability built into the head and does not require external hardware changes.
Do you ship Spectra Polaris 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.
