This Ryobi 3304 HA is a used four-colour press — sometimes referred to as a four-colour offset press — dating from 2007. Four-colour presses are commercial printing machines designed to reproduce full-colour work by laying down four successive ink impressions, typically cyan, magenta, yellow, and black, in a single pass through the press. Ryobi is a well-established Japanese manufacturer with a long history of producing sheet-fed offset printing presses for commercial printers, trade shops, and print-on-demand operations worldwide.
The press is configured for a sheet format of 320 × 460 mm, placing it in the small-format sheet-fed category suitable for a wide range of commercial print jobs. It is equipped with remote control operation, allowing press settings to be adjusted from a central console, and features semi-automatic clamping of printing plates, which streamlines makeready between jobs.
Dampening is handled by a Ryobimatic humidification system with MGE cooling, a dedicated solution that maintains consistent moisture delivery to the printing plates and helps stabilise ink-water balance during longer runs. The press also includes a powdering unit, which applies a fine coating of anti-setoff powder to freshly printed sheets as they are delivered, preventing ink transfer between stacked sheets.
Additional equipment included with this machine comprises a Punch Ryobi RP 520-220F register punch, a Schneider envelope loader, and an Ergoline envelope unloader, making this a well-equipped configuration for production environments handling envelope printing alongside standard sheet work.
