Sun-Times publisher and editor-in-chief Jim Kirk tells Romenesko readers:
Tribune’s printing plant somehow received an unedited version of the page long before deadline Thursday evening. A few hours later when we sent the edited version of the page that included the headline, that page didn’t get on the press. Ordinarily we get papers delivered between editions. That didn’t happen Thursday night, so no one in our building saw the problem before our last edition. We are investigating every aspect of the process in an effort to make sure something like this doesn’t happen again.
In terms of the e-edition [which had the correct headline]: we push all the pages for the e-edition from here after the final edition. So the e-edition carried the final edited page.
