Xaar has launched a new printhead, the 501 GS8, which is aimed directly at the wide format graphics market. It uses a new PrecisionPlus architecture that builds on Xaar’s Hybrid Side Shooter design. It optimises the actuator performance for better drop velocity, drop volume and drop placement profiles giving consistent colour across the print swathe for better print quality with smooth tints, gradations and edge definition.
It can print in binary mode at up to 1440 dpi with an 8 pL drop size or with 4 grey levels at 360 dpi to deliver high productivity with an effective resolution of over 600 dpi. It is compatible with a range of solvent and UV inks.
There’s an option to use Xaar’s TF recirculating technology, which reduces sedimentation when using heavily pigmented inks such as white, extends maintenance cycles and improves reliability. There are two modes for the TF technology: Pulsed mode recirculates ink during non-printing periods only; High Flow gives continuous ink flow at a high rate directly past the back of the printhead nozzles during drop ejection to carry away any air bubbles or unwanted particles.
The new 501 head will be shown for the first time worldwide at this week’s Shanghai International Ad & Sign Technology & Equipment Exhibition.
