Konica Minolta launches successor to KM-1 sheetfed digital press

  • AccurioJet KM-1e
by Andy Thomas-Emans, strategic director
Konica Minolta has launched the AccurioJet KM-1e sheetfed inkjet press, successor to the established KM-1 B2+ LED-UV press for the commercial print market. 
UV inkjet technology allows the AccurioJet KM-1e to print, without pre-coating, on a wide range of media including plastic substrates, foiled and embossed paper, metallic media, canvas and synthetic substrates. It will accept paper stocks in a thickness range between 0.06mm and 0.6mm.
The press prints at a resolution of 1200 x 1200 DPI at 3,000 B2+ (585 x 750mm) sheets/hour, with automatic duplex printing at 1,500 s/h.
An exciting development on the KM-1e is a new online interface allowing direct connection to third party post processing lines. Konica Minolta is working closely with partner MGI on integrating MGI’s JetVarnish digital embellishment equipment with the KM1-e, including digital varnishing, digital cold foil and laser cutting. A tape inserter further improves work efficiency in post-processing.
The AccurioJet KM-1e prints in four colors in a single pass. The imaging system uses Konica Minolta’s patented Dot Freeze technology (DFT) to ‘self-freeze’ ink drops immediately upon contact with the substrate. This works by a rapid change in temperature which turns high-viscosity inks coming from the printhead nozzle into a low-viscosity, immobile ink droplet when it hits the material. Konica Minolta says this eliminates mottling and allows printing on porous materials while extending the CMYK colour gamut, reducing the need for special colors.
Toshi Uemura, executive officer in Konica Minolta’s professional print division, said: ‘The AccurioJet KM-1e is a key pillar in our strategy to help our customers seize the many new opportunities digitalization brings along, supporting the trend to switch from offset to inkjet printing in a fast-growing market.’
