Seiko SPT510 Printhead | 35PL & 50PL Industrial Inkjet Head
The Seiko SPT510 printhead is a durable binary piezo head for grand-format signage, coding and industrial graphics. Its 510 active nozzles provide 180 npi native resolution across a 71.9 mm print width, with 35 pL and supplier-listed 50 pL configurations for compatible oil, UV and solvent ink systems.
Why choose the Seiko SPT510 print head
SII Printek describes the current 510BN as a stable binary industrial inkjet printhead for harsh production environments. The broad drop range, optional heater and durable platform suit large-format coding, outdoor graphics and high-coverage advertising work.
Industrial drop-on-demand piezo
The SPT510 uses piezoelectric drop-on-demand technology for reliable binary jetting without thermal ink ejection.
Two production-focused drop sizes
The 35 pL version favours finer detail, while the supplier-listed 50 pL version provides heavier ink laydown for high-throughput graphics.
Industrial ink compatibility
The platform supports validated oil, UV and solvent ink systems. It is not officially listed for water-based aqueous ink.
Flexible machine integration
A parallel interface, single ink inlet and optional heater support custom grand-format and coding-system designs.
