Letwin, who leads the party's policy development, paid a visit to the four-staff company to see the work being printed on its third Xerox machine.

The Dorchester-based company specialises in fine art repro prints, as well as marketing for trade publishers and London design agencies.

Its £350,000 machine is 25-30% more productive than its predecessor. At the time, Anderson said that the purchase was a result of the company's longstanding relationship with Xerox and the printer replaces an existing iGen3.

The digital printer was also the UK's first Xerographic printer to meet the Fine Art Trade Guild print standard.
