This Ryobi 928P is a used 8-colour offset press, a category of sheetfed printing machine — sometimes referred to as a perfector press in configurations where both sides of the sheet are printed in a single pass — used in commercial print production for high-volume, multicolour work across packaging, publishing, and general commercial printing. Ryobi is a well-established Japanese manufacturer with a long history of producing sheetfed offset presses for the print industry worldwide.
Built in 2012 and currently located in China, this machine carries an impression counter of 165 million, reflecting substantial but typical use for a press of this class. It operates in two configurations: straight printing at up to 16,200 sheets per hour in 8+0 mode, and perfecting at 13,000 sheets per hour in 4+4 mode, allowing double-sided printing in a single pass without re-feeding.
The press accepts sheet sizes up to 920 × 640 mm and handles stock thicknesses from 0.04 mm to 0.6 mm, making it suitable for a wide range of substrates from thin papers through to light board. Dampening is handled by an alcohol dampening system, which is well suited to high-speed production and consistent ink-water balance.
Automation features are extensive. The machine is equipped with automatic plate changing to suit both packaging and book work, an automatic impression cylinder washer, an automatic blanket washer, and an automatic roller washer, all of which reduce makeready times and operator intervention between jobs. Ink control is managed via a dedicated desk with a display, and print quality is monitored through a PDCG print control system, providing inline density and colour management.
