Waterless Plate (PEARLdry™ Plus)
The 3404DI uses PEARLdry™ Plus,a roll-type
waterless plate.This plate uses laser action to
form surfaces that are either adhesive or repellent
to ink.Each plate lasts for approximately 20,000
impressions,and will accommodate both short
runs as well as longer,large-lot production.
Note: The number of available plate impressions depends on
printing conditions such as the type of ink and paper
stock used.
High Printing Quality From an Offset Press
RYOBI has packed the 3404DI’s compact body with a host of
outstanding printing features.Incorporating RYOBI’s unrivaled offset
printing know-how,it features a highly reliable,robust design that
yields high printing quality and promises a long and productive
service life.
Dimensions
Compact Design Based on a Unique
CylinderArrangement
The 3404DI uses a satelliteV-shaped 5-cylinder
system consisting of two sets of double-
diameter blanket cylinders and plate cylinders,
which rotate around a triple-diameter impres-
sion cylinder. Paper is tightly held by the
impression cylinder grippers and rotated twice
without a gripper change for precise 4-color
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 3404DI
achieves a compact design that’s about the
same size as a conventional 2-color press.

Three Plate Cleaning Devices
Once imaging has been completed, plate
cleaning is carried out by three devices—a dry
cleaning device,a wet cleaning device and a
vacuum,to remove residual silicone on the
plate.

Solid,Reliable Design
The 3404DI uses a bearer contact system to
maintain constant plate pressure with each
rotation of the cylinder.Plus, induction-
hardened ultra-high-precision helical gears and
cylinders fitted with ultra-high-precision
bearings ensure consistent,stable printing
quality over long periods of use.

PaperTravel
Sheets are fed one-per-rotation of the
plate and blanket cylinders.The paper
is held by the impression cylinder
(surfaceA). Blanket cylinder 1 prints
the first color.
Blanket cylinder 2 prints
the second color. The paper printed with the second color is not transferred to the
delivery section, but enters the
second rotation while being held by
the impression cylinder grippers.
During the second rotation,
blanket cylinder 3 prints the
third color on the sheet.
When blanket cylinder 4 finishes
printing the fourth color,the sheet
is delivered to the delivery pile.

Ink RollerTemperature Control System
Roller temperature is maintained at an optimum
level by circulating temperature-controlled water
(warm water and cold water) inside the oscillating
rollers and fountain rollers.By minimizing fluctua-
tions in ink roller temperature,consistent printing
quality is maintained,even during long print runs.

Thanks toAdvanced On-Press
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

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.

operation stand based on this data.This allows
easy control of the ink fountain key opening
volume,dramatically reducing the time and effort
involved in making color adjustments.
RYOBI Program Inking
RYOBI Program Inking automatically supplies ink
to the ink rollers to match the image from the
very start of printing.After the set number of
prints is finished,the ink on the rollers is auto-
matically restored to an even state,allowing the
operator to proceed quickly to the next job and
minimizing the amount of wasted paper generated
at the start of printing.
The RYOBI 3404DI is loaded with automated processes,from
plate advance and imaging to making color adjustments—
operations that once required high levels of experience and skill.
Its user-friendliness ensures that even operators with little
experience can achieve quality printing in a short period of time.
