On-press digital plate imaging
Advanced New Imaging System with a 16μm Laser Spot Size
Presstek's newly developed ProFire® Excel Imaging System is equipped with two imaging heads with built-in lasers. The two imaging heads can simultaneously form an image onto the plates for four colors with precise registration on each plate cylinder. The laser spot size* of 16μm provides a resolution of 2,540 dpi, ensuring high-precision printing reproducibility. This imaging system can handle AM screening up to 300 lines per inch (120 l/cm) and FM (stochastic) screening (option), providing the flexibility to meet the growing demand for a diverse range of short-run color printing.
*Spot size as measured on a ProFire® Digital Media plate after imaging.

Waterless Plate (ProFire® Digital Media)
The 3404X-DI and 3404E-DI both use ProFire® Digital Media, a roll-type waterless plate. High-powered lasers form the print image on the plate. Each plate lasts for approximately 20,000 impressions, and will accommodate both short runs as well as longer, large-lot production*.
*The number of plate impressions depends on the printing conditions such as the ink type and paper stock.

Fully Automatic Plate Advance
and Take-Up Mechanism
 With the simple click of a button, new printing plates are positioned automatically and the used plates are wound onto take-up spools. An optional plate saver kit advances each plate the minimum distance necessary for each colour according to image size.

Compact Design Based on a Unique Cylinder Arrangement
The 3404X-DI and 3404E-DI use a satellite V-shaped 5-cylinder system consisting of two sets of double-diameter blanket cylinders and plate cylinders, which rotate around a triple diameter impression cylinder. Paper is tightly held by the impression cylinder grippers and rotated twice without a gripper change for precise 4-colour printing. The large diameter of the impression cylinder reduces paper curling as well as damage to the printed material. Thanks to this cylinder arrangement, the RYOBI 3404X-DI and 3404E-DI achieve a remarkably compact design that is about the same size as a conventional 2-colour press.

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.
|
Ink Roller Temperature Control System
Roller temperature is maintained at the optimum level by circulating temperature-controlled water (warm water and cold water) inside the oscillating rollers and fountain rollers. By minimizing fluctuations in ink roller temperature, consistent printing quality is maintained, even during long print runs. |
Built-in Ryobi IVS (Ink Volume Setter)
Image area calculation software. Converts digital artwork into ink duct profiles, dramatically reducing asker times. Runs from a Windows PC, and is has a similar structure to the popular Harlequin RIP system. Can be independent or piggybacked to your existing RIP.
|
Convenient Auto Print Function
The Ryobi 3404X-DI and 3404E-DI feature a convenient Auto Print function. Printing starts by just selecting the Auto Print command on the operation stand's monitor screen. Plate advancing, imaging, printing and blanket cleaning are all carried out with the click of a button.
|
Wide Paper Range
Ryobi DI presses are flexible enough to handle a variety of paper qualities, from regular printing paper to label stock and envelopes.
Simple, Easy Paper Size Changes to Match the Job
Both the feeder table and the delivery table dolly are hoisted by motors. A convenient paper size change button allows quick and easy resetting of the paper guides for different sized stock. Paper sizes can be changed quickly and efficiently whenever the operator needs to start a new print job. |
Ryobi PDS-E(opt)
The Ryobi PDS, Ryobi PDS-E Spectro and RYOBI PDS-E Spectro AUTO measure the color bar of the printed sheet using special sensors in a spectrophotometer(densitometer is used for PDS-E and PDS-E AUTO).Values needed to correct colour densities to match those of the OK sheet are calculated and provided as feedback to the RYOBI Printing Control System which, in turn, makes appropriate adjustments in the openings of the ink fountain keys. Colour profile setter: Option with PDS-E. ICC profiles can be made quickly and easily.

Shortened Drying Times with an Infrared Dryer
The delivery section can be equipped with an infrared dryer* to shorten drying time for printed materials, especially effective for jobs with short turnaround times. It also allows the use of powder sprays to be reduced for a cleaner working environment. *3404X-DI: Standard, 3404E-DI: Option
|
Supports Both PostScript and PDF
The Ryobi 3404X-DI and 3404E-DI support both PostScript and PDF files created in either a Macintosh or Windows® environment. The 3404X-DI and 3404E-DI are open and flexible systems that fuse the prepress and press processes. Features include the optional RYOBI DI Converter, which converts 1-bit TIFF data created on raster image processors (RIPs) from other manufacturers into 3404X-DI/3404E-DI-ready print data.
Advanced RIP (Raster Image Processor)
The RIP for the Ryobi 3404X-DI and 3404E-DI utilizes Harlequin RIP (PostScript Level 3 compatible), which has a proven track record of performance and offers high speeds and reliability. |
MIS Connection Software (for CIP4-JDF) (option)
Software to enable printing process management from a MIS (Management Information System)Boost productivity by integrating workflow including production, sales and administration.
|
Ryobi Print Job Manager (option)
The Ryobi Print Job Manager connects Ryobi printing presses in a network to perform centralized production schedule management by optimally assigning job data to each press. It also gathers real time information on operating status and automatically generates productivity assessment data for each press. Print Job Manager is a powerful support tool for printing companies who want to boost productivity.

UV Printing Capability
The UV curing unit quickly dries surfaces printed with an exclusive waterless UV curing ink, eliminating the time normally spent waiting for the ink to dry, so work can move immediately to subsequent processes such as back side printing,  sheet cutting and bookbinding. Job turnaround time is dramatically reduced and there is no need for extra drying space. Combining UV printing with the high print quality of offset printing greatly enhances versatility. The cold type system adopted for the UV curing unit generates very low levels of ozone and less unwanted heat. The heat from the UV lamps is reduced by an air-cooled pipe, a water-cooled housing and a water-cooled tube. A water-cooled plate assures greater safety when transferring printed materials. Odour and unwanted heat at the delivery section are discharged via an exhaust duct to maintain a clean work environment. |
