Komori GX40 offset printing machine

The legendary Lithrone S Series has evolved to become the Lithrone G Series. Komori introduces the innovative Lithrone GX40 - the ultimate expression of Komori's technologies and expertise. In addition to extremely stable printing at a maximum speed of 18,000 sheets per hour, even on heavy paper, the Lithrone GX40 offers significantly improved print quality and greater agility in color changes.

It has enough potential to cover high-end editorial and commercial printing as well as packaging printing, thanks to its outstanding print quality and reliability. It offers everything you need to cover a wide range of needs, such as automatic non-stop operation and control systems to manage long runs at high speed; advanced automatisms; new cleaning systems; and the availability of special configurations for high added value jobs.

Categories: Print, Offset

Specifically, new functions and systems for packaging printing have been added. The compact machine design that helps save energy, coupled with low heat emissions, offer real benefits for the environment. The Lithrone GX40. Komori's flagship to meet the highest demands.

Automatic high-speed operation to handle long runs and deliver world-class performance in luxury packaging printing. With a sheet thickness range of 0.06–1.0 mm, this machine offers stable operation at the maximum print speed of 18,000 in. Thanks to a new sheet feed and exit system.

Equipped with a fully automatic nonstop system, long run printing at full print speed is possible through an optional media transport logistics system.

The machine's high-speed long-run performance enables packaging to be printed on heavyweight materials, an industry with ever-increasing demand. A powerful new automation system, which integrates a paper flow throughout the printing machine and the entire plant, ensuring high productivity and profitability.

Control system

KHS-AI (Advanced Interface) is a productivity enhancement system that optimizes various presets through self-learning based on changes in the machine, environment, and media, and achieves high-precision startup.

In addition, KHS-AI ensures stable sheet entry and exit thanks to air presets that adapt to sheet size, thickness, paper type and grain direction.

Smart Sequence achieves a practically automated work sequence. Not only does the system make it easy to monitor jobs and manage the activity log and maintenance data, it is also equipped with a self-diagnostic function that helps prevent problems.

These features shorten changeover and make-up times, save resources and reduce machine downtime.

Special surfactant for ink rollers

In packaging printing, color changes are frequent in each task, as well as changes from dark colors to bright colors. Previously, ink cleaning sometimes took a long time to reduce color contamination when changing colors. Special surfactant for ink roller, rubber and print cylinder wash cycles minimizes color contamination by changing from dark colors, gold, silver, white, fluorescent and photoresist or UV colors to bright colors such as yellow. In addition, it optimizes cleaning work when changing colors and improves productivity.

Ink mist eliminator

This machine reduces the amount of ink mist generated in the inker that is dispersed outside the printing machine, as it absorbs and collects it with a special filter. This helps to reduce maintenance of the air conditioner and peripheral devices, as well as to decrease the need for cleaning maintenance of the printing machine.

Automatic Anilox Roll Changer

When varnish thickness is changed, the anilox rollers must also be changed. However, due to the weight of the rollers, changing them can require a great deal of time and maneuvering. The Komori Automatic Anilox Roll Changer automates the roll changing process. The unique structure of our drum unit allows the rollers to be changed and placed in printing position simultaneously, reducing operator workload and dramatically increasing the time required for changing rollers. If the varnish is not also changed, changing the rollers requires less than three minutes, allowing jobs to be processed continuously.

PDF comparator

Sensors to read the printed image and compare it with the data in the original PDF file. The system can be included in PDC-SX. In this way, the operator can look for characters that are surplus or missing in the initial phase of printing, thus avoiding production losses.

Sheet numbering system,

It lists each sheet in the feeder, and masking software *, which automatically creates inspection areas in advance from the die data, can be specified with PQA-S. This improves the quality control of packaging printing.
