    Gain an Edge with the new EJ-640 Large Format Digital Printer

    More than a job, it’s your reputation coming out of that printer. Which is precisely why the EJ-640 large format colour printer is designed to ensure quality results even at high speeds:

    • Dual eight-channel Piezo inkjet heads house 180 nozzles per channel

    • Advanced media feed allows media to feed through the printer accurately at high speeds

    New, specially formulated, quick-drying EJ inks produce amazingly brilliant colours. The inks also provide unmatched long-term outdoor durability, scratch and chemical resistance, broad media support and a wide spectrum of colour. And the available 1-Litre cartridges allow the EJ to run without frequent cartridge changes. Need more? Configure it for dual-CMYK or CMYKLcLmLk for finer details, smoother gradations and more neutral grays (made possible with Light Black ink).

    Free Up More of Your Time

    Because the EJ-640 large format colour printer doesn’t need constant attention, you can concentrate on other important tasks. Here are just a few features that get you through longest print runs:

    The EJ-640 dries prints quickly – even in high-speed mode – for immediate finishing, installation or collection by the take-up system.

    The integrated tri-heater system features:

    • Pre-heater to improve media receptiveness
    • Print heater to accelerate ink fastness and brightness
    • Dryer to accelerate drying and ensure greater productivity and scratch resistance

    An optional dryer/blower unit evenly dries large prints and enhances image saturation at high speed.
