Polaris PQ-512/85 AAA Printhead 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.
Primary Applications
