Skeleton Transfer Cylinder Specification Adds Versatility
to the RMGT 970 Model of A1-Plus Size Offset Presses
RYOBI MHI Graphic Technology Ltd. (RMGT, President: Katsushi Hirokawa) has announced theaddition of a skeleton transfer cylinder specification to the 970 model, popular for its exceptional
cost performance and advanced operator assist functions. Sale of the presses with the newspecification will begin in August 2023.
The newly developed skeleton transfer cylinder specification option for the 970 model corresponds
the demands from commercial printing to light package printing.
In addition to the flexibility to handle sheet thicknesses from 0.04 to 0.8 mm, the maximum feed
size of 650 x 965 mm is ideal for a wide range of multi-up printing on A1-plus size sheets, providing
exceptional cost performance. Employing many of the flagship RMGT 10 series’ sheet transporttechnologies together with a skeleton transfer cylinder, it can handle a wide variety of printing work,
including packages, cards, mounting boards, and book covers.
With the launch of the skeleton transfer cylinder specification for the 970 model enabling low-cost, highquality light package printing, RMGT is contributing to the creation of new business opportunities forprinting companies.

1. Features
1) Generate new business through added flexibility for commercial printing
Handles sheet thicknesses from 0.04 to 0.8 mm for printing packages and various sales promotion
materials on substrates, expanding business opportunities.
2) High flexibility
The maximum sheet size of 650 x 965 mm enables the flexibility to handle a wide variety ofmulti-up jobs on A1-plus size sheets.
3) Enhanced competitivenessLow-cost light package printing is achieved thanks to approximately 20%* lower plate costs andabout 65%* lower power consumption compared to an RMGT B1-size press.
* In-house comparison: actual results will vary according to operating conditions.

14) Sheet transport mechanism incorporating RMGT 10 technologies
From the feeder, register and printing unit, the press employs RMGT flagship 10 series
technology to ensure stable transfer and prevent scratches for a wide range of paper thicknesses.
●Improved heavy-stock feed performance*Changes to the feeder board section and infeed section—including the runner wheels and afront lay swing sheet guide—improve heavy-stock feed performance.
●Pneumatic side lay device with push-pull mechanism*
To increase side lay pulling force and enhance register precision for heavy-stock, the pneumaticside lay is equipped with a push–pull mechanism that simultaneously operates the side lays on
both the operation side and drive side.
●Skeleton transfer cylinder*
A skeleton transfer cylinder has no cylinder surface to touch the image area, preventing
scratches during paper transfer. Three air management mechanisms— an air blower before theimpression cylinder, an air chamber and a venturi system —ensure reliable sheet transfer forwide range jobs of paper thicknesses.
* Including in a skeleton transfer cylinder specification.

5) Capable of high value-added printing using special colors and coating varnishes
Combining a coating unit and LED-UV/UV curing unit with 2- to 6-color printing units enables
a variety of high value-added work, including chemical embossed printing using varnish as wellas printing on metallized paper.
●Retractable chamber type coating unit
This model adopts the retractable chamber type coating unit, which can apply a wide selectionof aqueous and UV varnish coating. When not in use, the coating unit retracts upward and asafety guard moves into position, enabling preparations for the next job to be performed while
printing is in progress.
