The magazine, Champions, will be published by Haymarket Customer Publishing in three languages. One hundred thousand copies will be distributed across Europe, selling at £3.50 and five euros.
The first issue goes on sale on September 10.
The branding will see the tournament use a more contemporary look, with a starball logo in polished silver. The Champions League anthem will remain the same.
The identity and magazine are aimed at reaching younger football fans, many of whom are unable to watch the games live on TV due to their 7.45pm (8.45pm CET) kick-off time.
The launch coincides with the re-signing of the competition's four main sponsors: MasterCard, Ford, Amstel and Sony PlayStation.
Each will be offered free advertising in the magazine and the chance to publish their own sponsored versions for distribution to clients and guests at matches.
