In the 1990s, when we were still relying on print documents at McKinsey, I would hold the deck against a strong light source to look through it to see whether repeating elements such as titles and page numbers were lined up properly. (Something like this cartoon machine)
"Jumping titles" are the result of slightly misplaced items on a slide sequence: when you hit page down and scroll through a series of slides quickly you see the titles moving up, down, right, and left. How to prevent it?
  1. Use drawing guides (excellent post on PowerPoint Ninja)
  2. Control-C object on one page, control-V on the next page. The element will appear in exactly the same location. Good for sequences of diagrams with buildups.
  3. Set the exact location of an object in PowerPoint (format ribbon, size, position)
