ADAST 557 DI is a four or five-color sheet-fed offset press, B3 size (15 x 20.5").

557 DI


  • Digital workflow right to the printing press
    • faster job turnaround
    • reduced make-ready costs
    • last minute edits possible on data files
  • Offset quality printing
    • real offset ink on a wide variety of substrates at the highest quality level
    • the quality of offset using real ink is far superior to toner based printing solutions
  • Waterless printing
    • waterless offset printing is a qualitive step ahead of conventional offset printing
    • makeready is shorter because no ink water balance vas to be achieved
    • high yield of quality printed sheets because there is no color variance due to changing ink water balance as the print run progresses
  • Fast make-ready of the press
    • complete jobchangeoner of up to 5 plates in less than 10 minutes
    • plates are imaged in register, cleaned automatically
    • the color profile is set on each printing unit from the plate imaging data
  • Digital printing workflow is fast
    • a fully digital workflow and short make-ready means fast job turnaround
    • ADAST 557 DI press is ideal for On-Demand printing, as well as fulfilment printing from digital archives
  • High speed printing
    • maximum printing speed of 12,000 i.p.h.
    • this high speed makes press economical even on slightly longer runs
  • Competitiveness even in case of low press run
    • the optimum use of ADAST 557 DI performs well in the range og 500 - 5000+ prints
    • compared to toner based solutions the 557DI can be the lowest cost from 200 prints, while delivering offset quality
  • Saving material costs
    • no film, film processing, and plate processing materials are used
    • lower waste sheets from the print run and the make-ready
  • Environmentally safe
    • no chemicals are used to develop the printing plates
    • the only waste from the process is the polyester plate
  • Digital print archives
    • archiving jobs electronically makes for easy retrieval for reruns
    • files can be distributed to multiple locations in a distribute and print' production model
  • Highly automated process
    • all operations - replenishing up to 5 plates, blanket washing, plate imaging, and plate cleaning are completely automatic
    • user friendly operation - the entire is controlled by the flat touch screen ' Communications Center'
  • Unique design of the imaging process
    • the ADAST 557DI uses a unique design that declutches the plate cylinder to allow imaging while the rest the press is idle
    • this reduces press wear while imaging, and allows for high speed imaging by the Presstek Pro-Fire imaging unit
    • all 5 plates can be imaged in 2 minutes and 40 seconds at 1270 dpi
  • Variable use of ADAST 557 DI printing presses
    • the press is available in four-color or five-color versions
    • perfecting is also available as an option
    • the five-color press may be used for 4/1 and 2/3 printing (with two perfecting units), the fifth unit can also be used for special colors, metallic ink, fluorescent ink or spot varnishing
    • the press may be fitted with an optional high-pile delivery
