Quad/Graphics Inc., which became the nation’s second-largest commercial printer through an acquisition last year, on Tuesday announced the closure of its facility in Mount Morris, Ill.

The Mount Morris plant encompasses approximately 644,000 square feet and employs about 230 people. Customer work will be consolidated at  other facilities.

“Today’s announcement is a necessary step to integrate operations, remove excess capacity from our platform and strengthen our overall competitive position,” Chief Executive Joel Quadracci said in a statement. “We remain resolute in our goal of creating the industry’s most efficient and modern manufacturing platform to benefit our clients and drive shareholder value.”

In reporting its earnings last week, Sussex, Wis.-based Quad/Graphics outlined measures to integrate struggling Canadian rival World Color Press Inc., which it acquired last year.

The “new Quad,” as it calls itself, has plants around the world and prints hundreds of titles including Newsweek, Wired, Time, Sports Illustrated and Rolling Stone magazines and the L.L. Bean catalog.

Quad noted that it’s carrying out the integration at a time when the global commercial printing industry is beset by overcapacity and many publishers are opening digital channels, compelling Quad to close North American printing facilities outside Wisconsin as well as World Color’s former headquarters in Montreal. It has cut employment by 3,000 to date; none of the plant closures were in Wisconsin.

The company has been adding jobs in its Wisconsin network of printing plants. It regards its Wisconsin plants as among its most efficient and productive.
