This Komori L428C is a used 4-colour press — also known as a four-colour offset press — a sheet-fed offset printing machine designed to apply four separate ink colours in a single pass, making it a core piece of equipment for commercial, packaging, and general print production. Komori is a well-established Japanese manufacturer with a long history of producing high-performance offset printing presses for the graphic arts and printing industries worldwide. This example was built in 1999, is currently located in Italy, and has accumulated approximately 97 million impressions.
The press is configured with four printing units plus a dedicated varnish (lack) unit equipped with a camera doctor blade system and two anilox rollers, enabling inline coating alongside four-colour printing. It runs at a maximum speed of 15,000 sheets per hour and accepts a maximum sheet size of 520 × 720 mm (20 × 28 inches), with a minimum sheet size of 230 × 305 mm. The usable print area measures 510 × 710 mm. Plate size is 600 × 730 mm at 0.30 mm thickness, and blanket size is 670 × 740 mm at 1.90 mm thickness. Stock thickness range is 0.04 to 0.6 mm. The overall machine footprint is 9.70 m long, 3.20 m wide, and 2.50 m tall, with a total weight of approximately 18,000 kg.
The delivery section is a high-pile configuration, raised 30 cm, and is paired with a long delivery unit. The press features chrome-plated cylinders and double-diameter transfer and impression cylinders, both of which contribute to careful sheet handling and consistent print quality across the range of stock thicknesses.
The included accessories and systems are extensive. Dampening is handled by the Komorimatic continuous dampening system. Ink and register control is managed remotely via the PQC console, which also controls the Cooking plate cylinder cocking function. The KMS4 monitoring system provides press oversight, while the S-APC semi-automatic plate change system reduces makeready time. Automatic wash-up is provided across three systems: AIRC for automatic ink roller cleaning, ABW for automatic blanket wash-up, and ICC for automatic impression cylinder wash-up. A Weko powder sprayer is fitted to the delivery, and an IR dryer is included. Sheet control features include electronic double-sheet detection and manual sheet thickness and sidelay preset. Steel plates are present on both the feeder and delivery sections. The press is offered complete with an oil drip pan, tools, documentation, and all standard parts and accessories.
