(Or "MultIPle Master Font") A font that is a mixture of two or more other fonts. A MultIPle Master font is a single font containing from two to sixteen master designs (the current implementation limit). A weight factor specifies the contribution of each master design for the creation of a multIPle master font instance. A MultIPle Master instance is a single interpolation of a multIPle master font as created by a user or application. {ATM Glossary (http://www.adobe.com/supportservice/devrelations/typeforum/glossary.html)}. {Useable fonts (http://susi.informatik.rwth-aachen.de/Mirror/winsite/win3/fonts_atm.html)}.
