Máquina impresión offset Komori GX44RP

The latest no-flip double-sided printing press compatible with the OffsetOnDemand concept follows the philosophy of the Lithrone G series.

The 44-inch GX44RP can be equipped with different UV drying systems *.
It is designed to offer high quality, short lead times, high speed, stability, and reduced waste in double-sided printing.

The new single edge grip system eliminates sheet flipping. This grip system makes the necessary margin at the end of the sheet - an unavoidable requirement in turning machines -, completely unnecessary, which allows to reduce paper costs by minimizing the size of the sheet. Elimination of blade tipping ensures stable transport being able to handle light or heavy materials through the use of four double size transfer cylinders. Front / back imaging is done in the same direction as with single-sided presses, increasing efficiency in prepress.
This machine expands the world OffsetOnDemand by means of a short set-up and instant dry without powders makes it a very interesting option for short runs and reduced lead times thanks to the integrated KHS-AI * 1 start-up control system and to the UV curing system *. . In addition, this press can be optionally equipped with the A-APC asynchronous automatic plate changing system, the PDC-SX spectral print density control system and the PQA-S print quality system for sheets achieving even higher levels. quality and productivity.
The Lithrone GX44RP stands for: state-of-the-art technology and knowledge to achieve automation, standardization and innovation in printing. A powerful platform for the new generation of printing companies.

It can be equipped with the following drying systems: H-UV • H-UV L (LED) or UV

Categories: Print, Offset

A high-speed, high-quality, single-pass duplex printing press, the Lithrone GX series offers high stability and fast makeready.
Labor-saving automated systems such as the KHS-AI (Advanced Interface) and Full-APC bend-free are standard equipment.
The single-pass, duplex printing press configuration, which does not use flipping, contributes to efficient paper use because the trailing edge margin required for a flipping process is unnecessary.
Equipped with the asynchronous automatic plate changing system (A-APC)*, it significantly reduces setup times.
Equipped with the H-UV / H-UV L (LED) * system, it allows for fast drying of the print and short delivery times.

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.
