A minimized 5pl droplet size and improved jetting accuracy yields excellent print quality without graininess. With 1,280 nozzles configured in 4 x 150dpi rows, this head achieves high-resolution 600dpi printing. Greyscale features a maximum frequency of 50kHz, allowing for increased productivity.
This head is compatible with UV, Solvent and Aqueous based inks. Specifically, the aqueous ink compatibility and service life of the MH5320/MH5340 is more than double that of the MH5421/MH5441 that preceded it.
