MEGA Jprint Series Providing Outstanding Performance for 44-inch Applications

It has been 15 years since Akiyama developed the Jprint Series Press, the world’s first single-pass sheet-fed press capable of printing on both sides of the sheet in multiple colors. Since then, the Jprint Series has achieved dramatic improvements in productivity and performance and has many new value-added features including a double-sided coater and Roll Feeder. In 2007 at the IGAS show held in Tokyo, Akiyama introduced the MEGA Jprint 40 series Perfector, a new model which brings together all of Akiyama’s experience and expertise into a single machine. In response to many requests for a larger format press, Akiyama then developed the MEGA Jprint 44 series, 44-inch (32-1/4″ x 44 1/16″) Perfector.
Check out the performance of the MEGA Jprint 44 series – the new standard in 44-inch Perfectors.

Non-Stop Feeder
The non-stop feeder ensures continuous sheet feeding during a print run by using the auxiliary paper tray.

Feeder Static Eliminator System
This system removes static electricity from the sheets as they are fed from the feeder.

Supersonic Double-Sheet Detection System
This system sends supersonic waves over the sheets delivered from the feeder, thereby detecting even small changes in sheet condition. If a double-sheet is detected, the system stops the feeder. The detection performance of the system has been dramatically improved.

Anti-Curl System in the Infeed Section
Air is supplied through an opening in the infeed section to prevent the sheet from traveling beyond the specified position, and at the same time the gripped side of the sheet is flattened.

Swing Fan-Out Prevention Mechanism
When the sheet is transferred from the swing to the transfer cylinder, its gripped end is straightened in order to prevent fanning as the sheet is printed.

Swing Air-Blower System
Air is blown onto the gripped end of the sheet while it is being transferred by the swing, and as a result the sheet is lifted and held during transfer. This has the added benefit of preventing the sheet from being scratched and marked by the swing gripper.

Transfer Cylinder Air-Blower System
Air is blown onto the transfer cylinder as it passes the sheet to the impression cylinder, thus preventing the sheet from wrapping itself around the transfer cylinder.

Special Impression Cylinder Jacket
Each impression cylinder is equipped with a special jacket. This jacket minimizes leftover ink, and as a result the problems commonly associated with ink buildup are eliminated.

Fan-Out Prevention Plate Lockup
This unique plate lockup, with its fan-out adjustment function, maximizes registration accuracy.

Blanket Cylinder Air-Blower System
This system evaporates the dampening solution that is transferred from the plate cylinder to the blanket cylinder, preventing the sheet from stretching due to the solution.

Continuous Dampening System
Akiyama’s unique roller configuration helps produce a uniform water film over the surface of the plate, facilitating consistently high print quality.

Water-Fountain Roller Drive System
The seamless speed variation achieved by a motor drive, coupled with a follow-up roller that operates in unison with the speed of the main press, promises stable dampening throughout every operation.

Inker Air-Blower System
Air is blown onto the inking rollers, which is minimizing the emulsification to what the print job requires.

Automatic Ink Roller Wash-Up System
Each time a color is changed, cleaning solution is injected onto the ink rollers to clean them, after which the dirty cleaning solution is collected. All these steps are performed automatically, helping make job set-up more thorough and efficient.

Inker Temperature-Control System
Three temperature-control rollers are used to ensure the constant temperatures of the ink-roller and plate surface, and thereby achieve stable ink delivery.

Antistatic Delivery System
The delivery section is equipped with an electrical antistatic system for the effective removal of electrostatic buildup.

Sheet-Release Cam Speed-Alignment Mechanism
The speed of the sheet-release cam is synchronous with the printing speed. Moreover, a unique speed-control method allows the operator to make the correct paper-thickness setting to support any type of sheet.

Air Regulation System for Sheet Alignment
A special air-shower system and fan provide consistent sheet alignment, even when printing on very thin stock.

Delivery Slowdown Suction Wheels Mechanism (split-type suction wheels)
The slowdown suction wheels can be moved right and left according to the image on the reverse side of the sheet. Additionally, the wheels of different widths can be installed to suite the image layout.

Flood Button
Raising the speed of the water-fountain rollers increases the volume of dampening to prevent the spoilage of the printed surface and other problems associated with the drying of the sheet.

The MEGA Jprint is a new style perfecting press offering a number of advanced functions for the sake of greater efficiency
and higher quality.

Printing Speed of 15,000 sph
The model MEGA Jprint 4p440 achieves printing speeds of up to 15,000 sheets per hour!

Suction-Tape Feeder with Improved Sucker-Head Durability
The feeder table employs an air-suction tape that creates a vacuum to reliably pick up and transfer the sheet to the swing table at high speed. The table also comes with a newly developed sucker head. Greater overall rigidity of this system ensures stable sheet-feed even at very high speeds of operation.

Lower Power Consumption, Greater Heat Resistance
The energy-saving design of the MEGA Jprint incorporates measures to limit negative impact on the global environment.

New Operation Stand (ACC)
The ACC (Akiyama Color Control) operation stand supports higher processing speeds. In fact, the values entered from the stand are executed by the ink keys in half the time required on a traditional stand, or even less. This makes it easier to design a CMS (Color Management System) to allow printing jobs to go full-scale more quickly. Akiyama’s original, simplified MIS is a standard feature. The plate data, ink-fountain data and various other inputs can be controlled for each job. When a repeat order is received, simply call up the past order to automatically restore the settings. Now all operation tasks can be performed via the touch panel, which makes operation easier than ever.

Additional Transfer Cylinders and Adoption of Belt-Type Sheet Guide
The delivery system has two additional transfer cylinders to reduce the unwanted movement of the sheet. The sheet-guiding endless belt protects the sheets from scratches and rub marks.

Detachable Slowdown Suction Wheels
An all-new structure of the slowdown suction wheel has been incorporated in the MEGA Jprint. The suction wheels can now be detached and attached along with the auxiliary suction wheels, while lateral movements are made easy with the crank handle.

Improved Roller Oscillation and Ink Air-Blow Method
The oscillation of the rollers has been improved to eliminate ghosting. Furthermore, the ink air-blow method has been modified to prevent the excessive emulsification of the ink while protecting the roller coating from peeling.

Inker Clutch (Optional)
The inking drive of a printing unit not currently being used for printing can be disengaged from the main power train through a simple operation on the touch panel, thus providing further energy savings. This mechanism also prevents the unnecessary wear of rollers not currently in use.

Full Auto Plate Changer (Optional)
You can also choose the optional FAPC (Full Auto Plate Changer). When the FAPC is installed, simply set the new plate on the plate guide, and all the required operations
