The Spectra Polaris PQ-512/15 AAA is a high performance inkjet
printhead designed for a broad range of industrial and commercial
printing applications at resolutions up to 1000 dpi. Robust
construction and repairable design make it ideal for solvent, UV
and aqueous based wide format printers built for demanding
production environments.
Building upon the legendary reliability and performance of the
Spectra Nova and Galaxy printheads, the Polaris PQ-512 AAA family
of printheads uses field proven materials and a repairable design
to deliver a long service life and consistent output. And by
leveraging the inherent flexibility of the Q-Class platform, the
Polaris PQ-512 AAA offers even greater jetting performance, nozzle
packing density, and configuration flexibility.
The Polaris PQ-512/15 AAA Printhead has 512 independent channels
arranged in multiple rows at 200 dots-per-inch spacing for single
color operation, or 100 dots-per-inch spacing for two color
operation. The printhead is designed for binary jetting using a
15-picoliter native drop size with 8-meters per second nominal drop
velocity for jetting fluids in the 8 to 20 centipoise range. Using
VersaDrop jetting technology, the printhead is capable of
adjustable binary operation at drop sizes up to 30 picoliters.
The PQ-512/15 AAA Printhead is compatible with a broad range of
inks, including UV-curable, aggressive organic solvent and aqueous
inks and associated maintenance fluids. The unique design of
Polaris PQ-512/15 AAA Printhead allows each 256-channel module to
be replaced and accurately registered in the field with no special
tools or recalibration. An integral mounting bezel with precision
registration points enables drop-in alignment with other carriage
features.
