Dainippon Screen shows new direction
with the introduction of Its first digital imaging solution - TruePress.

Dainippon Screen Mfg. Co., Ltd., (headquarters: Kyoto Japan; president: Akira Ishida) announces the introduction of its first digital imaging system - TruePress, which will make its world-wide premiere at IPEX'98 in Birmingham, UK in September.

Incorporating Screen's renowned expertise in the field of high quality digital imaging devices and proofing presses, the TruePress is a compact, highly automated imaging and printing solution for the rapidly changing print industry where, the importance of going digital, to reduce lead-times and overheads has increased with the growing demand for short run printing.

The TruePress solution comprises of the NP-1500, which houses the digital imaging and print units and the HC-110 a high performance controller that handles a variety of tasks such as job control and RIP processing of page files.

Running on a PC platform under Windows(r) NT, the HC-110 incorporates an Adobe(r) PostScript(r) 3(tm) RIP and utilises the latest JAVA technology that enables it to be controlled from either a Macintosh(r) or Windows LAN client. Features include soft proofing of the job on-screen, job scheduling, as well as generation of the ink control data to name just a few.

On the NP-1500, flexible plates are imaged directly on the cylinder where resolutions of up to 3,000 dpi and 175 lpi are supported. Full automation including plate loading, unloading, exposure, development and registration is provided.

After imaging, printing is made using the offset printing process that provides a level of quality approaching that of conventional stand-alone offset presses. TruePress can print at speeds of 4,000 impressions/hr for four-color work or 8,000 impressions for two-color work. TruePress employs conventional process inks. Paper format is up to and including A3+ where a range of stock up to 0.3 mm can be utilised. As well as the standard single-sided printing, double-sided printing is available by use of a perfecter sub-system. Using this option one or two color work can be printed at the same speed as single sided three or four colour work.

Other automated functions that remove the tasks from traditional press operations include blanket cleaning, printing pressure adjustment and ink area control.

The TruePress has been designed to handle the ever-increasing diversification of work that is made today by most prepress service bureaux and printers. These include proofing on the final printing stock up to four color short-run.

The first TruePress commercial unit will be shipped in January 1999.
