Alcatel-Lucent PowerPoint Design Guidelines
When necessary Portfolio/Program Name can wrap to a second or third line to maintain consistent typographic spec
For title slide only, a 5% gray background has been added
General specifications
Page Setup set to “On Screen” format
Update footer to include appropriate “Portfolio/Program Name”
Ensure that only one font “Trebuchet” is used throughout. Following pages provide font sizes for text and graphic pages.
Ensure all text boxes sit in proper location. Sometimes the automatic PowerPoint settings are not exact
Titles on slides, Agenda and Division pages use “Title Case”
Text is set predominantly with regular weight. Bold Trebuchet is used to highlight key words or phases
When a slide has more text than comfortable fits on the page using standard font sizes, treat this instance as an exemption and reduce the font size of the entire block until it fits
For graphic only slides, use as much of the object area as possible to enhance legibility and emphasis
Slides with multiple logos should be adjusted so all logos appear visually equal in size and weight
Please remove any tinted or light color backgrounds from slides other than Agenda and Division slides
