The Q-Class platform has enabled FUJIFILM Dimatix to develop new families of high-performance printheads and jetting assemblies that deliver the largest range of drop sizes, broadest ink compatibility, and higher packing density than previously possible. Shared physical features allow printer designs to be easily migrated across different model types and printing applications. The Polaris PQ-512/35 AAA further expands upon Q-Class with a 512-jet design, new spot size capability, and aqueous ink support.
Employing a durable metal nozzle plate and utilizing the binary operating capability of Dimatix’ VersaDropTM jetting technology, the Spectra Polaris PQ-512/35 AAA printhead delivers adjustable ink drop sizes of 35 to 80 picoliters from 512 individually addressable inkjet nozzles. Remarkable jet straightness is achieved at continuous frequencies up to 30 kHz with an 8 meters/second drop velocity.
The new Spectra Polaris 512/35 AAA printhead is equipped with a flexible, fluid interface allowing single or two-color operation. As an AAA designated printhead, the new Polaris now supports aqueous ink formulations in addition to UV-curable, and aggressive organic solvents, making it suitable for a growing range of commercial and industrial printing applications such as wide-format graphics, textiles, ceramics, labels and secondary packaging at resolutions to 800 dpi.
An integral mounting bezel designed with precision registration points enables drop-in alignment – a unique repairable feature allows each 256-channel jet module to be exchanged and accurately registered in the field without the need for special tools or recalibration. Each 256-channel jet module is also dual-ported to facilitate ink flushing and recirculation. Heaters and temperature sensors allow precise control of ink viscosity at jetting temperatures up to 60oC.
