Mitsubishi has developed a new sheetfed offset press available in a size format of 750mm x 1050mm that significantly enhances net productivity and operability. The new press – designated the DIAMOND V3000 – will be unveiled at IGAS 2007 in Japan on 21 September, at which time the press will become available for global sales.

The sheet-fed printing market has been facing stiff competition from commercial web offset in high-volume runs and electronic printing in short press runs. The inline folding processes of web presses and the variable information features of electronic printing systems provide these respective markets with significant benefits. For sheet-fed presses to remain competitive, it is necessary to improve the addedvalue features of high printing quality and printed product diversification.

The boom in product diversification along with the trend towards smaller lot runs, however, have resulted in greater sheet-fed press downtime, as makeready and press adjustments tend to reduce the operation rate of the printing plant.

Mitsubishi, as a world-renowned press manufacturer, already offers quality control through digital technology and inline processes. In the development of its DIAMOND V3000, Mitsubishi set out to improve net productivity of sheet-fed printing by minimizing press downtime from mechanically related causes, simplifying press operations, and placing even greater emphasis on operator safety and environment friendliness. The result is a press that realizes increased sales potential by increasing the total net operation rate of the press.

In short, the DIAMOND V3000 can be summed up as a press of outstanding performance that is extremely operator friendly and remarkably stylish.

Among the many features of the DIAMOND V3000 are the following:

• Application of international design featuring “soft geometric styling” The simple yet modern ergonomic design features bold cuts and gentle curves, providing outstanding accessibility and operability realized through the collaboration of a team of international industrial designers and Mitsubishi’s own engineering group.



• LED displays of press operation status



• Maintenance mode features that simplify required tasks Includes measures that minimize printing problems, such as scumming, and simplifies other tasks through adoption of non-lubricating bearings, torsion bar for the gripper shaft, automatic positioning of lubricating points, automatic lubrication, and removable dampening water tank.
  
  In addition, an optionally available powder retraction system is available to prevent powder buildup within the delivery.



• Improvements in press operability Includes the application of bender-less plate clamping and improvements in plate changing device, presetting functions, such as impression pressure preset and delivery preset, and wizard function, such as batch preparations.



• Newly developed simultaneous plate changer “SimulChanger” and color adjustment interface
  – DIAMOND Color Navigator – are also optionally available.
