  • The EJ-640 can produce up to 63 sq m of print per hour
  • Offset-positioned print heads move in a large print pass 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, even at high speeds
  • The Roland Intelligent Pass Control system controls dot placement between passes, producing exceptional solid colours and photographic image quality
  • Variable dot control achieves smooth gradations and deep image saturation on a broad range of media
