Supports Both PostScript and PDF
The RYOBI 3404DI supports both PostScript
and PDF data in the Macintosh andWindows®
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.

ImagingTechnology
•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
register.
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 IdealWork 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. ItsWindows 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 orWindows-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 ProcessingThanks to Shorter
Make-ReadyTimes
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.

Shortened DryingTimes 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.
