RYOBI 3404DI

A3-Size Portrait Format 4-Color Offset Press with Built-in Direct Imaging

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.

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.

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.

During the second rotation,	When blanket cylinder 4 finishes

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.

Ink roller temperature control system

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.
