Before you print a publication, it’s wise to check the publication for errors. You should make sure that you didn’t accidentally create, move, or resize objects so that they overlap, spill into the margins, or otherwise just look funny. To check your publication for errors, choose Tools | Design Checker. This displays the Design Checker dialog box.
Select the All option button to check all of your publication’s pages and click OK.
If Publisher spots a potential problem in your publication, it alerts you to the problem and provides a suggested solution. You can choose to ignore the problem or to solve it.
