LINCOLNSHIRE, Ill. September 10, 2007 -- Portable DRA is the latest advancement in Digital Register Analysis, Mitsubishi's exclusive press performance measurement and analysis system. Portable DRA is the only system that can identify the cause and location of complex mechanical problems in any size or make of press and recommend appropriate solutions. It absolutely determines whether a problem is mechanical or lithographic in nature.
Portable DRA enables Mitsubishi service technicians to analyze a press's mechanical performance at the customer site. Analysts can confirm the manufacturing precision of new equipment at the time of startup. Print tests done in the field on existing presses will help shorten service visits and reduce costly downtime.
A specially designed test sheet contains computer-recognizable patches. Portable DRA measures unit-to-unit, sheet-to-sheet movement on the gear side, operator side, lead edge, tail and infeed (in both horizontal and vertical directions). The quantitative evaluation is expressed in microns.
Portable DRA consists of a high-resolution desktop scanner with automatic document feeder, a powerful laptop computer and a color laser printer. It is adaptable to various scanning devices and can evolve to meet changing hardware and operating systems.
A typical Portable DRA analysis takes about an hour to complete. It replaces subjective judgments about whether a press is "good enough" with documented proof of performance.
Mitsubishi Lithographic Presses will demonstrate Portable DRA in booth #617 at Graph Expo 2007.
