3404DI

Supports Both PostScript and PDF

The RYOBI 3404DI supports both PostScript

and PDF data in the Macintosh and Windows

environments, and achieves the fusion of

prepress and press in a flexible, open system.

In addition, by using Ethernet to link the

RYOBI 3404DI to a digital front-end system,

digital data received from the prepress side

can be printed directly with impressively fast

turnaround times.

Advanced Digital Technology To Boost Productivity

High-Speed, High-Precision Imaging

Thanks to Advanced On-Press

Imaging Technology

• FirePower™ multi-beam lasers developed by

Presstek loosen the silicone layer on the

surface of the plate, directly forming the

screen dots. The RYOBI 3404DI is equipped

with two imaging heads. Both imaging heads

contain six laser modules, each of which

emits four laser beams. A total of 24 laser

beams burn the image onto the two plate

surfaces (two colors) on each plate cylinder.

• The two imaging heads burn the plates for

the four colors simultaneously in precise

Select from Either 1,270 or 2,540 dpi

Imaging Resolutions

You can select 1,270 dpi or 2,540 dpi resolu-

tion depending on turnaround times and

quality of printing demanded. The laser spot

size* can be formed in two sizes—28 µm at

1,270 dpi and 21 µm at 2,540 dpi. The 2,540

dpi setting enables output equivalent to 200

lines per inch.

* Spot sizes were measured on the PEARLdry™ Plus

plate after imaging was completed.

From prepress directly to the press—direct imaging technology from

Presstek incorporated into the RYOBI 3404DI makes it possible to

completely eliminate the need for analog intermediate processes such as

film output and image exposure onto the plate. The RYOBI 3404DI

raises productivity even with frequent job changes, and is the ideal

system for short-run color printing jobs that demand quick turnarounds.

An Ideal Work Flow for Digitalization

The rapid transition of prepress operations to computer-based digital

processes and the spread of the Internet have made it possible to send

original document data directly to the printer over ordinary telecommu-

nications networks. By incorporating the RYOBI 3404DI into corporate

network environments, it can be positioned as a high-performance

output device.

Advanced RIP

(Raster Image Processor)

• The RIP for RYOBI 3404DI SV770 utilizes

Harlequin ScriptWorks (PostScript Level 3

compatible), which has a proven track

record of performance and offers high

speeds and reliability. Its Windows NT

Server operating system also has a long

established reputation for stability and

functionality. Optimized bitmap data for

printing is generated quickly based on

PostScript or PDF data received from a

Macintosh or Windows-based computer.

• Generated bitmap data can be previewed

on the RIP or on the monitor screen at

the operation stand, allowing for quick and

accurate verification of text and the print

image.

• An optional color printer plug-in makes it

possible to network with an EPSON ink

jet color printer for proofing of layout and

text.

Faster Processing Thanks to Shorter

Make-Ready Times

The RYOBI 3404DI carries out high-speed

imaging for four plates simultaneously thanks to a

high-speed plate cylinder rotation of 18,000 rph.

This allows four-color imaging in approx. 4 min.

30 sec. at 2,540 dpi and approx. 2 min. 20 sec. at

1,270 dpi. Printing operations are fully automatic,

from plate advancing and imaging to presetting

the ink fountain keys and running a test print.

Even at 2,540 dpi, make-ready time is short—

approx. 9 min. from plate advance to start of test

print, dramatically increasing productivity.

printing plates are positioned automatically,

and used plates are wound onto take-up

spools. Each roll contains 28 plates.

Shortened Drying Times with an

Infrared Dryer (option)

The delivery section can be equipped with an

infrared dryer to shorten drying time for

printed materials, an especially effective option

for jobs with short turnaround times. Also, the

use of powder sprays can be reduced for a

cleaner working environment.
