Ryobi, Miyakoshi Develop Next Gen Liquid Toner Press

TOKYO, JAPAN | Miyakoshi Printing Machinery Co. Ltd. and Ryobi Ltd. have jointly developed a 6-up, 29-in. liquid toner-based digital printing press. It is reported to be the world’s first digital sheet-fed press in its class capable of B2-size printing at up to 8,000 sheets/hr. The new press will be exhibited as a pre-market model at the Miyakoshi booth (Hall 9, Stand A04) at drupa.

“This ‘next generation’ printing press is a significant milestone in Ryobi’s 68-year commitment to innovation and the success of printers worldwide,” said John Torrey, president of Ferrostaal Equipment Solutions North America.

Digital printing technology has been attracting wide interest for its ability to handle short-run variable data printing with short lead times, and a variety of digital presses are already on the market. But traditional offset printing technology still offers many advantages over digital printing, including higher printing quality, lower running costs, faster printing speeds, and the ability to handle long-run jobs.

This has led to strong demand for a new type of press that combines the strengths of both technologies. Responding to that need, Miyakoshi and Ryobi jointly developed a new type of digital press that enables high-speed printing on media as large as B2 size with quality comparable to that of an offset press.

The new press combines the 1,200 dpi high resolution and ultrafine particle liquid toner electrophotographic technology Miyakoshi demonstrated on a web press at drupa 2008 with the high-speed sheet feed technology Ryobi has perfected for its sheet-fed offset presses.

Through offset transfer of ultrafine particle liquid toner from a photosensitive drum to the media, this new digital press is able to offer high printing quality comparable to offset printing. Although recent advances have been made in commercial inkjet printing quality, this high level of quality is not yet achieved with an inkjet system, the company reports.

In addition to short-run printing applications such as catalogs, posters and packages, the new B2-size liquid toner-based digital printing press is called ideal for high quality, large-size variable printing. Based on the response it receives at drupa 2012, preparations will move toward its market release.
