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.

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.
