Where it should be used
Related Logos
with a derived logo such as edubuntu or kubuntu it is recommended that this font be used. Changes to kerning are permitted however kerning reductions are advised against.
Printed Documents
This is a title font and therefore not to be used in body text. Use it for topic headings in ubuntu-related printed documents or in digital documents where fonts can be embedded or subset such as PDFs.
Extending This Font
Ubuntu-Title was made using Inkscape and FontForge.
http://nitrofurano.linuxkafe.com/linux/UbuntuTitle_0706252006.zip (1021kb) - 7 different weights for UbuntuTitle (from skinny to bold), in ttf, otf and svg font formats - some fixes and intensive testing are needed, but very probably useful for Ubuntu related graphisms
more to be added soon
