The new machines were installed at the communication specialist's Redruth site in July, joining another GD9630 that was taken on in September last year.

The printers were chosen as upgrades for the company's three ComColor 9150 machines. Head of operations Steve Rowson said that the company had considered high-end continuous-feed systems, but opted for the GD9630s due to their lower cost and easier setup making them more effective for short-run work, despite lower running speeds.

“We were looking for an updated and innovative printing system that will bring additional value to our customers' printed communications,” he said. “A number of factors attracted us to the GD9630s – total cost of ownership, flexibility, ease of use, quality of output and productivity.

“This all meant there were no other serious contenders for cut-sheet inkjet. We will use the machines for critical customer communications and also the reprinting of mail that has been diverted via our inserter integrity system.

“Paragon CC Redruth has enjoyed several years of strong partnership with Riso; a partnership is how I would characterise the relationship. We have previously had ComColor technology and the service and support during that time has been exceptional.”

Riso’s ComColor GD9630 Line-type inkjet system runs CMYK plus grey at resolutions of up to 600dpi and speeds up to 160ppm simplex and 80ppm duplex.

The GD9630s run alongside one remaining ComColor 9150, as well as a Canon Océ continuous inkjet printer, a Canon Océ Variostream 7650, a Ricoh Pro C9110 and a Xerox Nuvera MICR production printer.

The site is part of Paragon CC, which is in turn part of the £616m-turnover Paragon Group.

It occupies a 4,920sqm site and employs 90 full-time staff.
