The new presses, which the company bought directly from Xerox, were installed in December and have replaced one of the company’s two Xerox 8000 digital presses.

According to finance director Keith Cooper, the company decided to upgrade due to the superior quality of the Xerox 1000, which has a list price of $395,000 (£253,880), and the optional fifth print station, which allows users to apply a clear dry ink.

Cooper said: "We chose the Xerox 1000s because they have the new clear ink technology, which is like a spot UV varnish, and the quality we can offer is superior."

Marketing manager Simon Lewington added: "Staff are now fully trained up on the new machines and we are delighted with the upturn in quality and productivity."

Cooper said that the investment, which is expected to reach £1.8m over the life of the machines, was aimed at growing the company's share of the "short-run quick turnaround market".

The Xerox 1000, which was launched last year, can print up to 100 A4 pages per minute on a maximum sheet size of 330x488mm and can handle stocks ranging from 55-350gsm.

The £3m-turnover Printroom Group, which was founded in 1977 by father and son team Ron and Barry Lewington, specialises in print management but also has its own litho and digital print facilities.

It has a design arm called Printroom Creative and in addition to its headquarters in Bracknell, the group has high street retail sites in Reading and Camberley.
