The firm will handle repro for annual supplements Which? Car 2007 and Which? Tax Saving Guide 2007.

The two titles will be added to Which? Money, a monthly magazine launched in February for which Zebra is also handling repro.

Bev Jordan, production manager at Which?, said: "We appointed Zebra to undertake the reprographics work for our latest magazine title, Which? Money, and have been really impressed by the quality of its service and the commitment of its team.”

Zebra sales director Richard Gambling added: “Having already undertaken the reprographic work for three issues of Which? Money to date, it’s encouraging to have now won the additional Which? business.”

The Which? Tax Saving Guide 2007, which was part of Which? Magazine until 1999, when it became a standalone annual supplement, will be published in June.

Which? Car will be published in July. It was first published in 1962.
