* Says plant employs 270 people

Oct 6 (Reuters) - Quad/Graphics (QUAD.N), a printer of magazines, catalogs and other commercial products, said it will close its St. Jean-sur-Richelieu printing plant in Quebec as it seeks to shift client work to more efficient plants.
The company said the St. Jean-sur-Richelieu plant, which employs 270 people, will begin stepping down operations immediately, and the company expects to cease production by the end of this year.
It said client work will be transitioned to other, more efficient plants within Quad/Graphics' existing network of facilities and the company will "proactively assist" impacted employees in finding new jobs, including those available at other Quad/Graphics locations.
Quad/Graphics said it will cut 30 jobs in its Edmonton facility as magazine and other commercial work currently produced in the Edmonton plant will be transferred to the company's Aurora, Ontario facility.
The company will also invest $23 million in its infrastructure and manufacturing platform within the next year.
