| RYOBI 684 685 686 A2-PLUS SIZE MULTI-COLOR OFFSET PRESSES |
RYOBI 684/685/686 is a unit construction type multi-color offset press (tandem type) which adopts the double-diameter impression cylinder and double-diameter transfer drum for its printing unit. Each printing unit has a built-in CPU system. In the new 684/685/686 offset press series there are 15 models from 4 color through 6 color with or without in-line coating capability.
RYOBI has developed a new Semiautomatic plate changer and incorporated it as standard. The Semiautomatic plate changer enables fast and accurate plate changing with simple push button operation. Furthermore several automatic preset functions including the paper size preset, pull guide preset, impression preset system reduces the paper setting time. RYOBI Program Inking allows the automatic pre-inking and pre-wetting (an initially even ink and dampening supply on rollers) and pre-sets the ink fountain keys for quick start of printing. Of course the blanket cleaning device, impression cylinder cleaning device and ink roller cleaning device, prerequisite for this large press class are available as options. At the operation stand of the newly developed RYOBI PCS-G, major press operations including counter setting, paper size input, registration adjustment, color adjustment and activation of the cleaning devices are performed at the delivery side, increasing the press overall operability and efficiency.
With the introduction of these automated features and advanced labor saving mechanisms, the time for make ready is reduced while increasing productivity.
RYOBI achieves the numerical value control of the printing quality with the introduction of spectrophotometry technique in the new printing density control system RYOBI PDS. Consistent high printing quality is assured with this technique even for repeated jobs or long run printing. RYOBI PDS will be of great benefit in establishing a stable quality control system at the factory.
Toward the new century of in printing industry, RYOBI offers the new A2-size multi-color offset press series, RYOBI 684/685/686, a genuine profitable press meeting the needs for high productivity, quality and versatility

| RYOBI 662HX/662PFHX WITH ADVANCED AUTOMATED FEATURES |
The RYOBI 662HX and 662PFHX offset press are loaded with advanced automated features, including the RYOBI semiautomatic plate changer, plate register remote control device, and optional ink roller and blanket cleaning devices, all of which dramatically shorten make-ready time, thereby increasing your productivity Futhermore, by adding the optional RYOBI PCS-J printng control system, you can make color adjustments with even high precision in a very short time. this system uses prepress data to simplify color control and adjustments, which previously relied on the operator's skill and experience, now allowing you to maintain a high level of quality. | The following new features and functions have been added on the 662HX and 662PFHX. |
| 1. | The standard RYOBI Semi-RPC Semiautomatic Plate Changer allows the printing plates to be changed quickly and accurately by push button operation. There is no need to bend the leading edge or tail edge of the plates. This system allows easy reuse of the stored printing plates and can handle polyester-based plates as well as metal plates. |
| 2. | By combination of the RYOBI RP 740-425AUTO or RYOBI RP740-425F High Precision Register Punch and the Semi-RPC, higher registration accuracy can be achieved from the start of printing. |
| 3. | The standard plate size of Semi-RPC is 650 x 550 mm(25.59 x 21.65"). For flexibility, the Semi-RPC can correspond to the plate size of 670 x 560 mm (26.38 x 22.05") by mounting optional plate clamp. |
| 4. | The plate cylinder cocking device allows diagonal image adjustment even during printing. [Diagonal image adjustment volume of maximum printing area: ±0.2mm (0.008")] |
| 5. | The RYOBI-matic continuous dampening system consisting of water form roller gear-driven mechanism, water fountain roller speed adaptation mechanism and optional oscillating bridge roller (same type as in the RYOBI 680 series) assures stable dampening performance. |
| 6. | The RYOBI AAC, Aqua Automatic Control System can be equipped as an option.This system automatically maintains the optimum dampening supply volume set by the operator. The RYOBI AAC significantly reduces the operator's task of adjusting dampening supply volume. |
| 7. | New single train inking mechanism highly rated for the RYOBI 680 series has been adopted to assure stable ink supply and superb response to ink volume adjustments. |
| 8. | The RYOBI Program Inking (available for the model with RYOBI PCS-J) automatically supplies ink to the ink rollers to match the image from the very start of printing. The image area data is calculated by the optional RYOBI Ink Volume Setter for PostScript data or RYOBI Ink Volume Setter-CIP4 for PPF and then converted using the RYOBI PCS-J to preset the ink fountain keys.
Making effective use of pre-press data greatly reduces the labor involved in adjusting ink fountain keys prior to production printing. |
| 9. | The RYOBI PCS-J new printing control system with the touch panel type liquid crystal display is available as option. With this device, ink fountain key preset via floppy disk from prepress system data, register controls and setting of RYOBI Program Inking can be done remotely from the delivery side. |
| 10. | Paper changing time is reduced with adoption of bellows type paper guides in the pull side guide section (which eliminates adjustment of bridge guides when the pull side guide position is changed), centralized impression pressure dials, in addition to paper size change button and integrated brush and runner wheels movement system. |
| 11. | The optional automatic cleaning devices for the blanket and the ink rollers reduce the operator's workload during color changes and maintenance after printing. | | The 662PFHX builds on the following superb basic features and functions of the 662PFH. |
| 12. | The 662PFHX adopts the unique satellite perfecting printing system that has the two-color front side printing units and single-color back side printing unit.
The double-diameter impression cylinder configuration for two-color front side printing eliminates gripper changes, assuring highly accurate two-color printing.
Simple unit selection done by switch allows quick printing mode selection for 2-color printing (2/0), perfecting (1/1), 2-color front side and single-color back side printing (2/1) , and 1-color printing (1/0). |
