StarFire SG1024/MA-2C Printhead
StarFire SG1024 / MA-2C 25PL Printhead
Spectra Starfire 1024 Printhead SG1024 MA-2C 25PL for Witcolor Gongzheng printer


The StarFire SG1024/MA-2C printhead is a breakout inkjet innovation for high performance printing and decorative applications. It is purpose-built for today’s demanding high-speed scanning and single-pass industrial systems designs. It is an easy to integrate, high performance, drop-on-demand printhead for two-color operation at resolutions up to 200 dpi. A robust and repairable construction makes it ideal for Textile, Wide Format and Commercial Printing and Decorating.

Combining superior jetting performance with a high nozzle packing density in a compact, self-contained unit, the StarFire SG1024/MA-2C uses field proven materials to deliver a long service life with consistent and reliable output.

Each SG1024/MA-2C printhead has two separate ink paths each with 512 independent channels arranged in 4 rows in a single nozzle plate for resolutions up to 200 dpi. All 1024 nozzles can be fired simultaneously or individually.

Equipped with a singular, durable, collar mounted, coated metal nozzle plate to withstand abrasion and resist damage, it is removable for cleaning or replacement. The printhead has a nominal 30 picoliter drop size with jetting fluids in the 8 to 20 centipoise range. When combined with VersaDrop™ jetting technology, the SG1024/MA-2C can produce drop sizes up to 80 picoliters and full grayscale without penalty to productivity.

The StarFire SG1024/MA-2C is compatible with solvent, UV-curable, and aqueous based inks and maintenance fluids. Using RediJet™ technology, the SG1024/MA-2C continuously recirculates inks through the printhead at the nozzle and refill chamber to increase open time, reduce downtime and improve startup, especially for highly pigmented and fast drying inks. RediJet allows StarFire printheads to be quickly and easily primed with minimal ink waste thereby increasing the inherent productive capacity of the printing system by reducing maintenance times and associated costs.

The StarFire SG1024/MA-2C printhead has simplified interfaces. The electrical interface consists of one 60-pin connector located topside for power, ground, data, control signals and fire pulse. Two fluid connections for each color channel facilitate easy priming, flushing and continuous ink recirculation and connect to an ink supply via Luer fitting.

Heating configuration includes an internal heater/thermistor for precise control of ink viscosity at temperatures up to 55°C. Precise registration points enable drop-in alignment with customer provided mounting features, reducing set-up and alignment costs during printhead replacement and also allow multiple printheads to be accurately arrayed into print bars for wide width, higher resolution and multi-color printing devices.
