Features

SOLJET 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 digital printer is designed to ensure quality results even at high speeds:

  • Dual eight-channel piezo inkjet heads house 180 nozzles per channel
  • Offset-positioned print heads move in a large print swath for increased production and follow a mirrored pattern to reduce the chance of banding
  • Advanced media feed allows media to feed through the printer accurately at high speeds
  • Rigid industrial design ensures quality output
  • Roland Intelligent Pass Control system controls dot placement between passes, producing exceptional solid colors and photographic image quality
  • Variable dot control achieves smooth gradations and deep image saturation on a broad range of media

Produce Rich, Vibrant, Durable Color for Less

New, specially formulated, quick-drying EJ INKs produce amazingly brilliant colors. The inks also provide unmatched long-term outdoor durability, scratch and chemical resistance, broad media support and a wide spectrum of color. And the available 1-liter cartridges allow the EJ-640 to run without frequent cartridge changes. Need more? Configure it for dual-CMYK or CMYKLcLmLk for finer details, smoother gradations and more neutral grays.
