Lithographic Multiple Color A2 Format Offset Printing Machine Book Printing
Model: Ecoo JY 44
Introduction:
This press is a four-color offset printing machine. It incorporates
the CC-LINK technology bus module from Mitsubishi for enhanced
functionality. Featuring a double-diameter impression cylinder with
a transfer drum design, it minimizes paper sheet transfer time
between printing units. The plate cylinder offers adjustments in
the circumferential, lateral, and diagonal directions for precise
printing control.
Highlighted Features:
1. Semi-automatic Plate Changer (APC) expedites setup time.
2. Allows for presetting paper thickness for various paper types
and automatic, rapid, and synchronized adjustment of printing
pressure in each unit.
3. Features a continuous feeder for uninterrupted production,
facilitating swift pile changes, particularly advantageous for
handling thick paper and long print jobs offline.
4. Integration with Mitsubishi's CC-LINK technology bus module
enhances operational capabilities.
5. Utilize a double-diameter impression cylinder and transfer drum
to minimize sheet transfer between print units.
6. Provides adjustable plate cylinder settings in the
circumferential, lateral, and diagonal directions for precise
printing control.
7. Incorporates five rollers on the plate cylinder, including an
intermediate roller in the alcohol damping system, effectively
eliminating ghost images, achieving rapid ink-water balance, and
reducing paper consumption.
8. Split (staggered) ductor features 23 zones for enhanced printing
precision.

Machine Spare Parts:
Feeder:
- Utilizes a synchronized cam system. The forwarding mechanism
regulated by a linear guide rail enhances machine speed and
stability.
- Incorporates a patented rotary valve for automatic paper dust
removal, minimizing potential faults.
Printing Components:
- The frame and base are cast as a single unit for structural
integrity.
- Transmission accuracy is ensured through high-frequency quenching
of gears.
- The use of helical gears with a high overlap coefficient
minimizes noise levels.
Cylinders:
- Impression cylinders and plate cylinders are coated with
stainless steel for enhanced durability.
- Incorporating dynamic balance design minimizes printing
vibrations.
Console:
- The press memory or job storage device (disk) retains the current
job details. Any modifications and adjustments made during the
current job are synchronized with the press.
- During printing operations, preset values for the next job can be
inputted into the press memory or saved onto a disk.
- CIP3/CIP4 compatibility is supported.
Pneumatic Clamp Bar, Change Plate Without Tools:
- The tension of the clamping bar is regulated using imported
tubing and disc springs, enhancing operational flexibility.
- Cylinder corners are monitored by a high-precision encoder.
Plates are automatically installed and removed through programmed
actions, accommodating both long and short-print job requirements.
- The tail of the clamping bar is designed to be detached,
facilitating smoother paper handling.
Ink Amount Control Console:
- Each ink control within every unit can be configured via the
console interface.
- Digital display of ink levels is available and can be stored for
future use.
Accurate Grippers:
- Enhanced longevity and easier replacement are facilitated after
heat treatment of the high-strength steel pads.
- The stability of paper transfer and precision in paper handling
is guaranteed by durable, abrasion-resistant soft pads.
- Improved the stability of the gripper system is achieved through
the use of high-precision needle roller bearings and articulated
bearings.
Automatic Device For Adjusting Paper Thickness:
Automated Paper Thickness Adjustment System:
- Utilizing gear drive technology, the distance between cylinders
can be automatically fed back to the screen via a potentiometer.
- Stability in printing pressure is ensured by a permanent magnetic
generator drive, known for its ample torsion and robust
self-locking mechanism.
- Direct input of paper thickness on the screen offers enhanced
ease and convenience.
Vacuum Suction Feeder Table:
- Equipped with a high-capacity imported air pump.- Capable of accommodating various types and sizes of paper
automatically, facilitating quicker and easier paper format
changes.
- Enhanced cylinder protection is provided by an ultrasonic
double-sheet detector.
