The GMG titles - published by subsidiary Greater Manchester Newspapers - include the Manchester Evening News, Manchester Metro News and the Express, Reporter, Observer, Times and Advertiser series of local newspapers in Greater Manchester.

The investment in four state-of-the-art press and inserting lines at MCP Oldham will greatly increase the colour and inserting capability of Trinity Mirror and Greater Manchester Newspaper titles in the North West.

The move is part of the two companies wider manufacturing strategy of enhancing their newspapers' quality while reducing costs and future capital expenditure.

Sly Bailey, Chief Executive of Trinity Mirror said: "This collaborative approach will deliver great value for all concerned. Both parties will benefit from what will be the most advanced printing presses in the world.

"The joint investment will enable Trinity Mirror to deliver a better service to readers and advertisers while significantly reducing the cost of re-pressing at the Oldham site."

Ian Ashcroft, Chief Executive of GMG Regional said: "The move to Oldham means all GMG's regional newspapers in the North West will be printed in full colour at the same plant. Combining with MCP maximises efficient use of pre-press, press and post-press capacity and has facilitated purchase of equipment to the highest technical specification in a plant with a proven track record."
