RYOBI-Matic Continuous Dampening System (Dampening Solution
Cooling/Circulation System)
The RYOBI-matic continuous dampening system assures a uniform dampening supply
onto the plate surface. Startup is quickly ready to enable an excellent response
of dampening volume adjustment. As uniform and stable dampening water can be supplied
quickly, thereby minimizing waste sheets during test printing and production printing.
In addition, as this system is equipped with a dampening solution cooling/circulation
system, printing can be performed without using alcohol.
Paper waste reduction by the "RYOBI-matic-D/RYOBI-matic-D
Remote" Continuous Dampening System with Hickey Removing Function
This Dampening system substantially reduces hickeys on plate by adopting the new
drive mechanism for the water form roller that creates a rotational speed difference
between the water form roller and plate cylinder. This system virtually eliminates
the need to interrupt press operation and remove hickeys from plates. So the paper
wastes due to hickey problem can be greatly reduced.

Paper waste reduction by the upgraded RYOBl Program Inking
The newly upgraded version of RYOBI Program Inking automatically sets the conversion
curve for each color according to the image area ratio calculated at prepress.
The ink key settings, ink fountain roller speed, and number of contacts by the
ink ductor roller are all controlled based on the conversion curves to assure
the optimum ink volume. New printing parameters for automatically correcting ink
density during job changes have been added to match the various printing conditions,
which enables to reduce the press down time and number of paper wastes.


Automatic Blanket Cleaning Device
Using
a cleaning cloth that is moistened with a cleaning solution of environmentally
friendly, lower VOC (Volatile Organic Compound) enhances safety for both the environment
and the human body. This device does not generate waste liquid.
Coating Unit and UV Curing Unit
|
UV printing employs ink that does not contain VOCs (Volatile Organic
Compounds), so there is no emission of such VOCs into the atmosphere.
By also reducing the amount of spray powder, it is further possible to
improve the operator's working environment.
Moreover, with printing presses that include a coating unit, glossy
prints using UV varnish coating and protection of the surface
of the printed sheet can be accomplished without using polyvinyl chloride. At Ryobi, we have not
only offered a UV curing unit for the delivery section but also an inter-deck UV curing unit that is
installed between printing units, and we are proposing a variety of high value-added printing
processes that take the environment into consideration.

RYOBI Fully Automatic Plate Changer Full-RPC/RYOBI Semiautomatic
Plate Changer
The
newly developed RYOBI Fully Automatic Plate Changer Full-RPC has been added to
RYOBI's 750 series of B2-size multi-color offset press. With the Full-RPC, plate
changing is fully automated with mounting and removal of the plates handled entirely
by button operation from a touch panel, so operators can prepare for the next
job while plate changing is underway. Using Ryobi's automated Full-RPC or Semi-RPC
units to deliver high precision to plate changing work also greatly reduces paper
loss incurred by registration prior to printing.
RYOBI RP740-425AUTO (High-Precision Register Punch)
The
RYOBI RP740-425AUTO uses a pair of high-precision CCD cameras to scan for registration
marks that are exposed on the plate. It then automatically adjusts the lateral,
vertical, and diagonal position of the plate, and punches holes in the plate to
match the image position. This punch additionally enhances the plate loading accuracy
of the RYOBI semiautomatic plate changer and reduces the amount of waste paper
that may be required for conventional registration adjustment.
Direct Imaging System
The
RYOBI 3404X-DI/3404E-DI adopt imaging method that images directly onto a plate
that is loaded on the printing press. This method minimizes toxic materials, such
as developer, that were required in the plate making process as well as materials
required for conventional intermediate processes, such as films.
