The Ryobi 3302 professional grade two-color offset printing press is available in three models: the 3302M, the 3302H and 3302HA. The models differ slightly. The 3302M is a single-lever model that uses molleton dampening, in which cloth-covered rollers absorb excess liquid. The 3302H uses Ryobi’s Super Dampener instead, which is a motorized continuous dampener. The 3302HA uses the same dampening system as the 3302H, but also features auto plate loaders.
The Ryobi 3302M, 3302H and 3302HA print on paper a maximum size of 13.39 inches by 17.72 inches. The Ryobi 3302M will also print on paper with a minimum size of 3.54 inches by 5.12 inches. The Ryobi 3302H and 3302HA models take smaller paper sizes, down to a minimum size of 3.54 inches by 3.94 inches. The paper used in all three models can vary in thickness between 0.0016 inches and 0.012 inches. All models have a maximum printing area of 12.99 inches by 17.24 inches.
The Ryobi 3302 prints between 3,000 and 10,000 sheets per hour, although the rate may vary depending on the ink type, paper stock and printing plates. All models use a two-color printing process use just two inks that you can blend to achieve many shades. The Ryobi 3302 can also four-color print -- also known as full color printing -- but each sheet needs to pass through the machine twice. This doubles the time requirements for any job.
The Ryobi 3302M printing plates measure 3.86 inches by 19.09 inches, while the 3302H and 3302HA plates measure 13.19 inches by 19.09 inches. This varies by plus or minus 0.04 inches in the case of the 3302HA, depending on whether the plates used are metal or polyester. The Ryobi 3302M is 7 feet 3 inches in length, 3 feet 2 inches wide and 5 feet 2 inches in height. The 3302H and 3302HA measure 7 feet 8 inches in length, 2 feet 10 inches in width and 5 feet 2 inches in height.
Optional accessories increase the printer's functionality. For example, the Ryobi PCS-F printing control system enables remote control of the ink fountain keys and offers operators the ability to download print data to disk. Other options include software to control ink volume settings, a blanket cleaning device, an electronic double sheet detector, a pile board for multiple paper sizes, a tape inserter, a non-resettable print counter that tracks the total number of sheets printed, an intermediate tank and a lever-control ink fountain.
