The group will print titles including New Scientist, Computer Weekly and Flight International at its Colchester and Watford web offset plants.

The extension is worth 25m, excluding paper, over the contracts duration and continues a relationship that has been in place for more than 35 years.

RBI operations director Martin Bloomfield said Polestars adoption of CTP had helped it to win the contract. Between 80% and 90% of RBIs advertising is now received in digital format.

Polestars commitment to CTP was important, said Bloomfield. Weve got well-established digital workflows.

Bloomfield also said Polestars performance had been very good.

The two additions to the contract are Commercial Motor and one title that RBI is yet to launch.

Earlier this year Polestar awarded its group-wide CTP contract to Creo and Heidelberg (PrintWeek, 26 April). Heidelberg was asked to supply workflow to Colchester, which already used its platsetters, while Creo won the deal to install CTP at the groups other UK web offset plants. Watford was chosen as one of its imaging hubs.
