Concept

High production efficiency and high rate of return of one-pass printing

The Lithrone G40P enables high-quality two-sided printing in one pass and straight multicolor printing in one machine. Equipped with Komori’s own high-performance perfecting mechanism configured by three double-size cylinders - impression cylinder, transfer cylinder and perfecting cylinder. Komori’s unique sheet transport system - enabled by the stress-free sheet transfer attributable to this ideal cylinder configuration and by the lower unit air control - allows two-sided printing at 15,000 sheets per hour. Stable sheet transport thanks to the minimal movement along with the small number of gripper changes reduces scratches and smears, lessens curling, and at the same time assures exceptional register accuracy.

In addition, a variety of automatic devices and systems, including the KHS-AI integrated control system, the benderless Full-APC system*, and suction drum lateral movement linked to paper size presets, slash the need for spare paper for printing and preparation tasks and also dramatically cut lead time. Superb performance with heavy stock in either single-sided or double-sided printing mode means that a variety of stunning high added value printing effects can be obtained with special inks and overprint varnish. The Lithrone G40 is a machine of matchless flexibility that addresses a variety of needs at the highest level. By maximizing the benefits of one-pass printing, the Lithrone G40 yields highorder print quality as well as outstanding productivity and profitability.
