System information

• TrueType fonts can print well on both non-PostScript and PostScript output devices. However,
to print well on a PostScript device, the TrueType font must be converted to PostScript outlines,
which may affect the visual quality of the resulting font. This is why many prepress service
providers are reluctant to support TrueType fonts.
• On Windows-based systems, a TrueType font is physically stored in a single file, the name of
which has the .ttf extension. On Macintosh, it is stored as a single Suitcase.
• You can recognize a TrueType font by the following icons:
TrueType font in Microsoft Windows
TrueType font in the Mac OS
• A TrueType font, or a combined use of TrueType and PostScript fonts in one document, may be
troublesome in high-end PostScript devices, especially imagesetters.
Multiple Master fonts
The Multiple Master font format is an extension of the PostScript Type 1 format. “Multiple Masters”
are fonts offering design variations at the extremes of the “design axis”. This design axis represents
a given variable property for that font, such as:
• Weight (light vs. bold)
• Width (condensed vs. expanded)
• Optical size
The mechanism of Multiple Master fonts is that the two masters at the extremes of the design axis
have a fixed design, but you can create any variation between these masters. Typically, Multiple
Master fonts have two design axes, which require four masters. These masters can be considered
the cornerstones of the matrix.
