Specifications

For PDF environments, ZapfDingbats is added to this standard font set.
PostScript Type 1 fonts
PostScript Type 1 fonts were originally developed by Adobe Systems for use in PostScript printers.
PostScript Type 1 fonts are outline fonts. They use lines and cubic Bézier curves to define letter
shapes or “glyphs”. A “glyph” is the shape in a font that is used to represent a character code on
screen or paper. Examples of glyphs are the letters of the alphabet or the symbols in a font like
ITC ZapfDingbats (i.e. ), J or 4).
Type 1 fonts have the following characteristics:
• They are smaller in file size than TrueType fonts, which means that they occupy less space on
your system’s hard disk.
• Being outline fonts, Type 1 fonts are scalable to almost any size. They remain sharp and smooth
on any platform and in print, and their legibility remains good, even when printed at small point
sizes on low-resolution laser printers.
• PostScript Type 1 fonts are commonly used in professional publishing environments and are
supported by most high-end output devices, because most of these devices use PostScript as
their page description language.
• A PostScript Type 1 font is stored in two separate files: one which contains the character outlines
and one which contains the font metric data. In Microsoft Windows, you can recognize these by
their extensions: *.pfb for the character outline and *.pfm for the one containing the metric
data. The former (.pfb) is commonly called the printer font, the latter (.pfm) is also known as
the screen font. The combined file size of both files, however, is smaller than the file size of its
TrueType counterpart. The file size of the PostScript font may sometimes even be as little as
half of the size of the corresponding TrueType font.
PostScript Type 3 fonts
PostScript Type 3 fonts are primarily decorative ornaments fonts with a lot of tonal variations and
filled-and-stroked objects in the same character. Indeed, Type 3 fonts can have grayscale fills and
strokes and other “special effects”, whereas Type 1 or TrueType fonts are entirely black.
Consequently, Type 3 fonts have the following characteristics:
• Their file size is bigger than the corresponding of Type 1 or TrueType fonts.
• They may take longer to print or output.
• They look worse than Type 1 or TrueType fonts in very small point sizes and when printed at
low resolutions.
• They are not always displayed well on screen.
Note: PostScript Type_3 fonts can’t be converted to outlines by PitStop Server.
TrueType font
The TrueType font format was developed by Apple Computer as an alternative to the Adobe Type 1
standard. It is used both on Macintosh and Windows computers.
Like PostScript Type 1 fonts, TrueType fonts also use outlines to describe the letter shapes.
TrueType fonts have the following characteristics:
• Their use is widespread and they are integrated in almost every desktop office software program
for Microsoft Windows or Macintosh systems.
