FEATURES
Wide Paper Size
The RYOBI 750W Series comes in two types: the SW type press with a maximum printing area of 765 x 545 mm, and the XLW type press with a maximum printing area of 765 x 580 mm, enabling a wider range of printing applications. The XLW type allows 6-up printing of 8.5" x 11" letter-size. The press can flexibly handle a wide range of paper from 0.04 mm onion skin to 0.8 mm thick cardboard. |
Cardboard printing (opt)
With a cardboard printing configuration, paper thicknesses of up to 0.8mm can be handled without adversely affecting the existing performance for thin papers. A very simple manual change will switch the thickness range from 0.04-0.6mm to 0.6-0.8mm with no requirement for gripper height adjustment. |
Suction Tape Feeder Board
The suction tape feeder board simplifies the setting of the brush and runner wheels and shortens the time required for changing paper sizes. The suction belt holds the paper securely and feeds it smoothly to the front lay. |
Double-Diameter Printing Mechanism
The printing unit consists of a double-diameter impression cylinder and a double-diameter transfer drum. These cylinders, which have a large curvature ratio, transport paper with minimum flapping, providing stable paper transport even when printing on heavy stock. |
Choice of plate changing
Semi-RPC allows plates to be changed quickly and accurately. The operator merely sets the plate on the positioning pins and presses the button. The Semi-RPC does not need the leading edge or tail edge of the plate to be bent.
With Full-RPC, both plate mounting and plate removal are automatically performed on all printing units in sequence with single button operation, freeing the operator from all plate changing work. The Full-RPC takes only about 4 minutes and 30 seconds to change the plates on an 8-color press, and eliminates human error for greater plate changing accuracy.

Ryobi Program Inking
Ryobi's program inking system automatically supplies ink to ink rollers to match the image from the early start of printing. After the set number of prints are finished, the ink on the rollers is automatically restored to an even state.

Ryobi-matic Continuous Dampening System
The Ryobi-matic continuous dampening system assures a uniform dampening supply on the plate surface to reproduce sharp halftone dots, glossy solids and finely detailed text. Starting is quick and this system is designed to minimize wasted sheets. The optional Ryobi-matic D Remote Continuous Dampening System substantially reduces hickeys by adopting a new drive mechanism for the water form roller that creates a rotational speed difference between the water form roller and plate cylinder. |
 |
RYOBI PCS-G Printing Control System
Almost the entire operation flow from make-ready through printing can be centrally controlled using the touch panel of the RYOBI PCS-G Printing Control System, greatly shortening make-ready time for changing the paper, cleaning, registration adjustment, color tone adjustment, dampening volume adjustment, and other tasks when switching jobs. |
Ryobi Print Density Control System (opt)
The Ryobi PDS, PDS-E Spectro AUTO, PDS-E Spectro, PDS-E AUTO and PDS-E Printing Density Control System measure the colour bar of the printed sheet using a spectrophotometer with special sensors (a densitometer is used for the PDS-E AUTO and PDS-E). Values needed to correct the colour densities to match those of the OK sheet are calculated and provided as feedback to the Ryobi PCS, which appropriately adjusts the openings of the ink fountain keys. Quality control that previously relied on human experience and intuition is now done using precise numerical values, contributing to consistent printing.
Options vary depending on model.

Various Dryer Units for High Value-Added Printing
 
An inter-deck UV curing unit can be installed over the storage drum, and a cassette type inter-deck UV curing unit can also be installed over the impression cylinder of each unit. Combining a coating unit and these UV curing units not only provides quick drying for a shorter delivery time, it also makes possible high value-added printing such as printing on film, metallized paper and other non-absorptive media, as well as chemical embossed printing and lenticular printing.
|
LED-UV curing
The 750 Series can also be equipped with an energy saving, eco-friendly LED-UV curing unit.
Inline Coating System
When the varnish coating system is not being used, the entire coating cylinder and anilox roller can be easily slid upward at the touch of a button to prevent marking on the sheet. Models with coating units offer a choice of an open type doctor blade system or an optional chamber type doctor blade coating system which features automatic setup and cleaning functions.
Automatic Cleaning Devices
Automatic blanket cleaning device, Automatic Ink roller cleaning device, Automatic impression cylinder cleaning device (option) |
Ryobi IVS
(Ink Volume Setter) (opt)
Image area calculation software. Converts digital artwork into ink duct profiles, dramatically reducing makeready times. Runs from a Windows PC, and has a similar structure to the popular Harlequin RIP system. Can be independent or piggybacked to your existing RIP.

Paper Size and Impression Pressure Presets (opt)
The RYOBI 750 Series allows the operator to enter preset values for paper size and thickness using the touch-panel display. Positions of the feeder head and delivery section guides* as well as pull guides* can be preset. Plus, an impression pressure preset system is also available.
*Standard equipment: The pull guide preset system, Options: Feeder head preset, delivery section preset, and impression pressure preset system |
 Fully Automatic Convertible Perfecting Device (750)
Switching between straight printing and perfecting can be performed remotely from the delivery side via the RYOBI PCS-G Printing Control System. The operator simply inputs the paper size and selects a printing mode from the touch panel display.
One-pass full-colour perfecting
Unlike a straight printing press, no time is lost waiting for the front side to dry after printing, or for paper piling when printing the back side. Printing time, obviously, is cut in half compared to printing both sides with two passes on a 4-color straight printing press.
