High Speed Stability

High speed, automatic, nonstop operation to handle long runs and deliver performance in deluxe package printing. Providing a stable operation at the 18,000 sph maximum printing speed thanks to new sheet feeding and delivery performance.

Short Makeready

Numerous automated devices are employed throughout the press to meet the diversifying needs of printing with high-level print quality. The Komori Full-APC Fully Automatic Plate Changer changes plates on six units in less than three minutes.

Quality Control Systems

The Lithrone GX40 can also be equipped with an inspection system that includes features such as the ability to inkjet-stamp numbers on the feeder board for identifying irregular sheets, or apply inspection and measurement data between processes.

Print Quality that Shows Real Value in Deluxe Printing

Komori solutions deliver value, with excellent reproducibility, inking, distribution, and high-precision printing with colours to accommodate the increasing diverse and deluxe printing needs. The GX40 is equipped with new functions, such as the inker roller train changeover function and the start-up density stability function. Each unit is equipped with the Komorimatic dampening system working in equilibrium with the high capacity ink train, incorporating an array of ink and dampening rollers for high-grade printing.

1. High-speed stability

Offering a sheet thickness range of 0.06-1.0 mm, this press provides very stable operation at the 18 000 sph maximum printing speed, thanks to new sheet feeding performance.

2. Automatic washing/cleaning

The new automatic ink roller washing system significantly improves colour changing, which can bottleneck when printing with special colours.

3. Automatic nonstop operation

Equipped with a new fully automatic nonstop operation system, the printing of long runs at the maximum printing speed is enabled through linkage with an optional stock transport logistics system.

4. PDF comparator system

A PDF comparator system, which uses sensors to read the printed image for comparison with the originating PDF file data, has been developed and may be specified with PDC-SX. This allows the operator to check for missing or added characters in the initial printing stage, preventing production losses.

High Performance Ink for H-UV Printing

H-UV / H-UV L (LED) Ink is the ideal Komori standard ink for H-UV printing that was developed with the know-how gained through the sale of H-UV systems.


The H-UV System is a UV curing system that uses high-sensitivity UV ink. The system offers reliability and economic and eco-friendly performance.

GX-40 RP for dedicated double-sided offset printing

The Lithrone GX40 has been designed to deliver high quality, short turnaround, high speed, stability and reduced waste in double-sided printing. A new system features single-edge gripping and eliminates sheet reversal. Single-edge gripping makes the margin on the tail edge of the sheets – an unavoidable structural requirement of perfectors – completely unnecessary, enabling paper costs to be cut by minimising the sheet size. Eliminating sheet reversal ensures stable sheet transport capable of handling either light or heavy stocks through the use of four double-size transfer cylinders. Front/back plate imaging is in the same direction, just as with single-sided presses, increasing efficiency in prepress.
