The move means the two companies will be able to expand the range of services they provide.
MMi Creative will fulfill all creative, design and production requirements for Blackburn-based Granby, which in return will provide MMi's entire direct marketing fulfillment.
Negotiations began in September 2004 and were finalised in January 2005, shortly followed by the completion of a new design and print management contract.
The companies say they are confident the new partnership will improve the quality of service offered to existing and future clients.
Richard Connolly, managing director of the MMi Group, said: "This partnership promises to be exciting and beneficial to both our organisations and especially to client companies."
