Standard Type 1 Fonts (Standard 14 Fonts)

The PostScript names of 14 Type 1 fonts, known as the standard 14 fonts, are as
follows:

    Times−Roman         Helvetica                Courier               Symbol
    Times−Bold          Helvetica−Bold           Courier−Bold          ZapfDingbats
    Times−Italic        Helvetica−Oblique        Courier−Oblique
    Times−BoldItalic    Helvetica−BoldOblique    Courier−BoldOblique


These fonts, or their font metrics and suitable substitution fonts, must be avail-
able to the consumer application. The character sets and encodings for these
fonts are listed in Appendix D. The Adobe font metrics (AFM) files for the stan-
dard 14 fonts are available from the ASN Web site (see the Bibliography). For
more information on font metrics, see Adobe Technical Note #5004, Adobe Font
Metrics File Format Specification.

Ordinarily, a font dictionary that refers to one of the standard fonts should omit
the FirstChar, LastChar, Widths, and FontDescriptor entries. However, it is per-
missible to override a standard font by including these entries and embedding the
font program in the PDF file. (See implementation note 62 in Appendix H.)

Note: Beginning with PDF 1.5, the special treatment given to the standard 14 fonts
is deprecated. All fonts used in a PDF document should be represented using a com-
plete font descriptor. For backwards capability, viewer applications must still pro-
vide the special treatment identified for the standard 14 fonts.

Multiple Master Fonts

The multiple master font format is an extension of the Type 1 font format that al-
lows the generation of a wide variety of typeface styles from a single font pro-
gram. This is accomplished through the presence of various design dimensions in
the font. Examples of design dimensions are weight (light to extra-bold) and
width (condensed to expanded). Coordinates along these design dimensions
(such as the degree of boldness) are specified by numbers. A particular choice of
numbers selects an instance of the multiple master font. Adobe Technical Note
#5015, Type 1 Font Format Supplement, describes multiple master fonts in detail.
