Journal Sentinel Inc. has made a three-year agreement with the Chicago-based Sun-Times Media Group to print 39 weeklies published by STMG-owned Pioneer Press, the Milwaukee Journal Sentinel reported on Monday.

The STMG has said it will close its Northfield printing plant to cuts costs as it makes its way through bankruptcy proceedings, according to a report Tuesday by The Associated Press. The closure is expected to include 70 jobs cuts. The transition to printing at the Journal Sentinel's Burnham St. plant will not affect readers or advertisers, according to the AP.

"Pioneer Press Publications join other newspapers we serve like the Kenosha News, USA Today, La Raza, and the Chicago Reader," said Elizabeth Brenner, president and chief operating officer of Journal Communications' publishing group.
