Abstract:

Effective visual design enhances the overall success of a manual as much as, if not more than, the other factors that go into its makeup. The presentation shows how we redesigned a 2-volume manual into a 6-volume manual and otherwise maximized the visual impact of the manual. The many examples of improved visual presentations show how important effective visual design is to the overall impact of the manual. While we also changed stylistic and organizational elements of the manual, we found the impact of the changes in the visual elements most powerful.
