High Printing Quality Fr om 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.

Compact Design Based on a Unique
Cylinder Arrangement
The 3404DI uses a satellite V-shaped 5-cylinder
system consisting of two sets of doublediameter 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-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.
Paper T ravel
Sheets are fed one-per-rotation of the
plate and blanket cylinders. The paper
is held by the impression cylinder
(surface A). Blanket cylinder 1 prints
the first color.
During the second rotation,
blanket cylinder 3 prints the
third color on the sheet.
Blanket cylinder 2 prints
the second color.
When blanket cylinder 4 finishes
printing the fourth color, the sheet
is delivered to the delivery pile.
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.

Solid, Reliable Design
The 3404DI uses a bearer contact system to
maintain constant plate pressure with each
rotation of the cylinder. Plus, inductionhardened ultra-high-precision helical gears and
cylinders fitted with ultra-high-precision
bearings ensure consistent, stable printing
quality over long periods of use.
Ultra-high-precision helical gears are used
on the impression cylinder
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.
11-Zone Divided Ink Fountains
Ink fountains are divided into 11 zones, each
having its own motor. The ink supply volume
for each zone is remotely controlled from the
operation stand.
Inking Mechanism
Each inking unit consists of 15 rollers including
4 form rollers, ensuring uniform inking.

Vacuum
Ink Roller Temperature 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 fluctuations in ink roller temperature, consistent printing
quality is maintained, even during long print runs.

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-Speed, High-Precision Imaging
Thanks to Advanced On-Press
Imaging T echnology
• 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 resolution 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.
Laser module
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.
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.
Fully Automatic Plate Advance and
Take-Up Mechanism
After four roll-type plates are set inside the
plate cylinder gaps (one in each cylinder gap),
the plates are advanced automatically and
simultaneously (Auto Plate Advance Mecha-

nism). With single-button operation, new
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

The RYOBI 3404DI is capable of flexibly handling a wide variety
of paper types and inks, and offers unmatched versatility. It can
handle many types of printing, ranging from pamphlets and
presentation materials to postcards.
Wide Variation of Paper
The RYOBI 3404DI can accommodate a wide
range of paper sizes and stocks to match the
printing job—from smaller-than-postcard size of
90 x 100 mm up to a maximum 340 x 460 mm,
and thicknesses from 0.06 mm onion skin to
0.3 mm card stock. It is also flexible enough to
handle a variety of paper qualities—from regular
printing papers to label stock and envelopes.
Simple, Easy Paper Size Change 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
paper guides for different stock size. Thus, paper
sizes can be changed quickly and efficiently
whenever the operator needs to start a new print
job.
Paper feed section
Push side guide registration
Push Side Guide and
Underswing Infeed System
• The push side guide ensures accurate paper
positioning on the feeder board. Consistent
registration accuracy is achieved even when
printing on the back side of the paper.
• Thanks to a simple, yet precise underswing
infeed system with cam-closed type sheet
grippers and an accurate front lay system, the
RYOBI 3404DI maintains stable registration
accuracy.
• Mechanical and electronic double sheet
detectors and multiple sensors monitor paper
travel. The OK monitor on the operation stand
clearly indicates the source of the paper trouble
so the operator can take quick action.
• Suction wheels and a decurling system come as
standard equipment, ensuring stable paper
stacking in the delivery section.
Waterless Offset Printing Inks
The RYOBI 3404DI uses waterless offset printing
inks. These inks are available in standard
process colors, as well as in
custom specialty colors
designed for printing spot
colors such as logos and
corporate names.
User-Friendly Operation Thanks to Automation
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.
Simple, Straightforward Centralized
Control from the Operation Stand
All major operations for the RYOBI 3404DI are
initiated and controlled from the operation stand.
Setting the number of printed sheets; job data
entry, interruption and recall; presetting the ink
fountain keys; and cleaning are all centrally
controlled from the operator’s position. A large-
format 14.1-inch LCD ensures user-friendly
operation.
Automatic Ink Fountain Key Presets
Calculating the image area ratio for each color is
done simultaneously with imaging. Presetting the
ink fountain key is done automatically from the
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 automatically 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.
RYOBI Program Inking Flowchart
Convenient
Auto Print Function
The RYOBI 3404DI features a
convenient Auto Print function.

by selecting the Auto Print
command on the operation
stand’s monitor screen. Plate
advancing, imaging, printing and
blanket cleaning are all carried
out at a click of a button.
Automatic Cleaning
Devices
The RYOBI 3404DI comes
standard with an automated cleaning system for
both ink rollers and blankets (including an impression cylinder cleaning function). This reduces the
cleaning time required when switching jobs, thus
lessening the workload for the operator.
RYOBI PDS-E
Printing Density Control System (option)
The RYOBI PDS-E Printing Density Control System
is an option on the 3404DI. Color adjustments
previously based on the experience and intuition of
