    Cardboard Printing [RYOBI 752G/RYOBI754G/RYOBI 755G/RYOBI 756G] (option)

    With the cardboard printing, paper thickness up to 0.8 mm (0.031″) can be handled without adversely affecting the existing printing performance for thin papers. These cardboard printing provide substantial functions to perform high quality printing with easy operation to meet a wider range of printing needs.

    • A very simple manual change will switch the thickness range from 0.04-0.6 mm (0.0016″-0.024″) to 0.6-0.8 mm (0.024″-0.031″). However, no gripper height adjustments are required on all grippers at a range of 0.04 mm thin paper to 0.8 mm cardboard printing and the make ready time when changing paper can be greatly reduced.
    • Double-diameter impression cylinders and double-diameter transfer drums ensure stable paper transport with minimum flapping, providing stable paper transport even when printing on cardboard.

    Reliable Paper Feeding Mechanism

    A High Grade type Feeder ensures reliable paper feed even when printing at a high speed of 16,000 S.P.H. 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 tape holds the paper securely and feeds it smoothly to the front lay.

    Efficient job changeover improves profitability

    RYOBI Semiautomatic Plate Changer Semi-RPC

    The RYOBI 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.

    RYOBI Fully Automatic Plate Changer Full-RPC (option)

    The RYOBI 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.

    Fully Automatic Simultaneous Plate Changer (option)

    The «Full-RPC» RYOBI’s conventional fully automatic plate changer ejects the used plates and then inserts the new plates one by one sequentially. Compared to this, the new «Smart-RPC» switches the phase of all plate cylinders to the same position, and then changes the plates simultaneously on all printing units. Thanks to this new system, plate changing can now be performed approx. 2 minutes even though it takes approx. 5 minutes using the conventional Full-RPC for the 928P (convertible 8-color perfector).

    Full-RPC (option)

    Automatic Cleaning Devices

    Automatic blanket cleaning device, Automatic impression cylinder cleaning device (option), Automatic Ink roller cleaning device (option)

    Paper Size and Impression Pressure Presets (option)

    The RYOBI 750G 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 side guide preset system, Options: Paper size preset, and impression pressure preset systems (The impression pressure preset system includes program-controlled impression cylinder cleaning function.)

    RYOBI Program Inking

    • RYOBI Program Inking 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.

    Various Innovative Mechanisms Guarantee High-Quality Printing

    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.

    Double-Diameter Printing Mechanism

    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 «RYOBI-matic-D / RYOBI-matic-D Remote Continuous Dampening System (option)

    These dampening systems substantially reduce hickeys on plates 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- including paper changing, cleaning, printing settings, registration, color adjustment, water control, and other operations -can be centrally controlled by the RYOBI PCS-G printing control system.

    Image Area Calculating Software [Ink Volume Setter/Ink Volume Setter-CIP4 (PPF)] (option)

    RYOBI Ink Volume Setter uses PostScript data created on Macintosh computers to calculate the image area ratio for each ink fountain key on a RYOBI printing press, while RYOBI Ink Volume Setter-CIP4 (PPF) uses CIP3/CIP4 (PPF) files created with CIP3/CIP4 (PPF)-compatible software on a PostScript RIP. The calculated data is loaded via a 3.5-inch floppy disk or through a network into a RYOBI Printing Control System connected to a RYOBI printing press. The system then converts the data into the opening degree of each ink fountain key.

    Printing Density Control System RYOBI PDS-E SpectroJet/ RYOBI PDS-E SpectroDrive (option)

    The RYOBI PDS-E SpectroJet, PDS-E SpectroDrive Printing Density Control System measures the color bar of the printed sheet using a spectrophotometer Values needed to correct color densities to match those of the OK sheet are calculated and provided as feedback to the RYOBI PCS-G, which appropriate adjustments in 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.

    Boost Productivity and Add Value

    Various Dryer Units for High Value-Added Printing and reduction of environmental impact

    An infrared dryer unit and/or UV curing unit can be installed in the delivery section. 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.
