The high performance Lithrone designed for today’s printing environment: the Lithrone G40

Green concept

The Lithrone G40 was developed as a “green”, environmentally friendly printing press

High performance

KHS-AI and H-UV and H-UV L (LED) work in concert to realise OffsetOnDemand – performance at the highest level

High-speed stability

The Lithrone G40 was developed to be a high-performance press that attains both high-productivity and high print quality by means of stable operation

The high performance Lithrone designed for today’s printing environment

The Lithrone G40 promotes green printing by reducing consumable and energy usage and lowering the carbon footprint of print. With a maximum printing speed of 16,500 sheets per hour, the Lithrone G40 is nothing other than the ultimate high-performance printing machine.

Lithrone G40 combines the state-of-the-art technologies from the LSX40 with the award-winning features of the LS40 to deliver a machine symbolising Komori’s commitment to the environment.

The Green Press

Ninety-five percent of the environmental impact of a press takes place during the usage stage. During this critical stage, Komori presses achieve a minimal impact by saving energy and resources through shorter makeready time, minimal paper waste, and reducing harmful chemical substances.

Ingrained Heritage

The technologies of the Lithrone S Series, with cutting-edge short makereadies, have been infused throughout the Lithrone G40. Automatic devices and systems are used to respond to the increasingly complex and diverse needs and demands of the printing industry.

Custom Lineup

The Lithrone G40 enables one-pass printing with a wide variety of in-line options and specifications, special inks, overprint varnish, and UV printing units. Specifying the press with one or more coaters or drying units enables high added value printing meeting an unlimited range of needs.

KHS-AI and H-UV/ H-UV L (LED) in concert realise OffsetOnDemand

The development goals of the Lithrone G40 were high-speed stability, improved print quality, suitability for short-run work, equipment reliability, environmental fitness and improved production efficiency. Equipped with the highly evolved KHS-AI integrated control system, the Lithrone G40 meets the needs for short job cycle time, competence with short runs, capability of producing many different printed products and cost reductions. The press offers a maximum printing speed of 16 500 sheets per hour and delivers very stable, high-speed operation with a user-specified sheet thickness range due to the incorporation of a new feeder and delivery.

1. H-UV / H-UV L (LED)

The Komori H-UV System is an innovative UV curing system that uses a UV lamp developed with Komori know-how and high sensitivity UV ink. With just one lamp mounted in the delivery, this system offers high print quality and reliability, as well as excellent economic and eco-friendly performance.

2. Improved delivery

As a result of improvements to the chain track and changes to the air control system, sheet behaviour is stabilised by shape optimisation. The stabilisation of sheet transport results in stable high-speed sheet delivery. 

3. Benderless Full-APC

Not only is the new Full-APC faster than previous systems, a benderless clamp is used, eliminating the need to bend the plates and making plate discharge and feeding more efficient.

4. Automatic cleaning systems

Efficient and automatic cleaning is delivered thanks to an automatic control programme. The quickest automatic blanket washing system in the industry is further enhanced with the use of pre-soaked cloth for blanket washing and impression cylinder cleaning. 

The Three Pillars of the Green Concept

The green concept has three pillars: clean (prevention of pollution), saving (conservation of resources) and safety. By implementing these three pillars, Komori has shaped the printing press of the future. A printing press that reduces paper waste, saves energy, improves the work environment and reduces noise. The Lithrone G40 is a green machine that protects the environment and is clearly worthy of being called the ‘Green Lithrone'.

The short-makeready performance critical for future success

These features support multiple jobs with differing printing conditions and ensure smooth operation. Significant reductions in makeready times are assured by the combination of ideal sheet feeding and delivery corresponding to the paper size, thickness, grade and grain along with the register presets.

The Lithrone G40 can handle the increasingly frequent short turnaround jobs, the press is not only versatile but it also ensures exceptional productivity and high profitability. This press is packed with the high-order performance needed in a reliable long-term partner to flourish and triumph in the printing business of the future.
