Technology of the third millennium

The DI technology employs direct transmission of the digital image in the computer to the printing plate in the printing press. The imagining process is executed by the means of 32 laser diodes.
The digital imagining technology serves as a bridge between all electronic pre-press systems and the printing press ADAST DOMINANT. Thus the full dat integrity from image setting to transmission to the printing plate in the machine is maintained.
The press processes are completely waterless, i.e. usual chemical wastes produced by dampening systems are eliminated.
We have won the time-race
Traditional offset printing methods require many time-consuming production steps and the setup time takes from 2 to 3 hours, while the DI press can do it in less then 20 minutes.

  • Advantages of the DI technology
  • Transmission of the printing image direct from the computer to the printing press
  • Elimination of the manual pre-press jobs and cut-down of make-ready time to one half
  • Reduction of error sources
  • Immediate color balance
  • Waterless print process
  • Higher ROI (Return of Investment) at smaller printing jobs
  • Material costs reduction up to 30%
  • Quick shift to new job, backup of jobs and fast search of archived jobs
  • Virtually no impact on the environment
  • Maximum production speed up to 10 000 iph
  • Sharp printing dot created by 32 laser diodes and height quality of the final impression
  • Advantages of the conventional printing technology are maintained

    Auxiliary equipment answers the purpose of additional jobs on the printing presses ADAST DOMINANT. It can be used for numbering, imprinting, cross and radial perforating, cutting and creasing.  The auxiliary equipment is located behind the last printing unit in front of the press delivery.  The print and auxiliary jobs can be provided at one sheet pass through the press.
    Numbering can be provided in cross and radial direction.  According to the kind of job many numbering boxes including special ones are available.  The necessary cams and numbering boxes can be ordered in the factory.
    Imprinting is executed as letter press with plastic clichés, which are glued to the supplementary print segments or discs.  The segments and discs can be set in the both cross and longitudinal directions.  The segments and discs are delivered in the basic accessories, on demands additional elements can be delivered afterwards.
    Cross perforating is executed by perforating knives mounted in the clamping bars on the numbering cylinder shaft.
    Two bars with different lengths according to the paper size are delivered in the basic accessories.
    Radial perforating is executed by perforating disc knives cutting against the steel pad glued on the surface of the impression cylinder.
    Creasing is executed by the same means as radial perforating (the perforating knife is replaced by creasing disc, which creases the paper against the rubber pad. The equipment for envelope creasing is delivered in the basic accessories.
    Cutting knife makes possible to divide sheets in half (bisect) in the longitudinal direction.
