Meet the new EJ-640 large-format color printer. With dual staggered print heads and a rigid new industrial design, productivity and quality are built in. So are big-time savings. The EJ-640 runs with new Roland DG EJ INK that costs up to 35% less than the competition. The result? High-volume, low-maintenance printing and bold, exciting colors with higher profit margins.

SOLJET® EJ-640 Large-Format Color Printer Features

Gain an Edge With the 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 color 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
  • Patent-pending 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 INK produces 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 to run without frequent cartridge changes. Need more? Configurable to dual-CMYK or CMYKLcLmLk for finer details, smoother gradations and more neutral grays (made possible with Light Black ink).

Count On a Quick-Dry Finish

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