The Ryobi 524 GX is a used 4-color offset press — sometimes referred to as a four-color litho press — designed for commercial sheet-fed printing. Ryobi is a well-established manufacturer of offset printing equipment, producing machines used across commercial print, packaging, and general trade printing applications. This example was built in 2008 and is located in Germany, offered in very good condition with a total print count of 55 million impressions.
The press handles a maximum sheet format of 375 × 520 mm and is available for immediate delivery. Its specification list is extensive. Ink density and color consistency are managed through the Ryobi PCS-H Printing Control System and the Ryobi PDS-E Printing Density Control System, which together provide closed-loop monitoring and adjustment of print quality across all four units. Dampening is handled by the Ryobi-matic Continuous Dampening System, and a Technotrans cooling and circulation device supports stable ink and dampening temperatures throughout the press run.
Makeready is supported by a Semi-RPC semiautomatic plate changer, reducing downtime between jobs, and a plate punch is included for accurate pre-registration of plates before mounting. Remote control of plate register — covering vertical, lateral, and diagonal adjustment — is available directly from the console, and preset functionality allows job parameters to be stored and recalled. Automatic washing systems cover ink rollers, blanket, and impression cylinders, keeping press downtime for cleaning to a minimum.
Sheet feeding is via a stream feeder with a suction tape feeder board. Sheet integrity at the feeder is monitored by both mechanical and electronic double-sheet detectors as well as an electronic missing-sheet detector, providing reliable protection against misfeeds reaching the printing units. Delivery is configured as a high-pile delivery, accommodating larger stacks between lifts. Anti-setoff powder is applied by a Grafix Digital 3000 powder spray device. The machine is described as being in very good condition and is available immediately.
