It involved the installation of new print equipment with supporting ancillary kit and an increase in floor space, as well as increasing staffing by 10 to 140.

Field Group marketing manager Bob Houghton said: "The expansion was driven by our pharmaceutical clients, who are required to provide more information to patients. We already supplied leaflets, but now we are able to offer cold-glued booklets that have the print quality of a real book."

The new service was a result of collaboration between Chesapeake and pharmaceutical companies to find a solution to the increasingly bulky and reduced type size booklets being used. The mini-booklets are typically the size of a credit card with up to 150 pages.
