Type formats: Postscript, TrueType and OpenType
When you make your own layout, one of the things you'll have to do is
choose typefaces. To do that well, you need to know a little bit about
type and typography. In this article, we will look at font formats.
The three digital type formats in use today -- Postscript, TrueType and
OpenType -- are all scalable (or outline) fonts. This means that the fonts
appear on screen the same way they will be printed. Each character is
made up of mathematically defined lines and curves. And the font software
includes a set of instructions that tell your computer and printer how
to draw each character at whatever size and resolution is required.
Of the three, Postscript (also referred to as PostScript Type 1, PS1,
T1 or Adobe Type 1) is the oldest. It was introduced by Adobe in 1985.
The original Postscript fonts were still bit-mapped on screen, but printed
beautifully on Postscript printers. For many years after this, if desktop
publishers and graphic designers wanted scalable fonts, their only choice
was Adobe.
Then, in 1991, Apple introduced TrueType in an attempt to get out from
under the high licensing fees charged by Adobe for using Postscript fonts
in its system software. TrueType fonts were even scalable on screen. Apple
then worked out an attractive licensing deal with Microsoft. In response
Adobe introduced Adobe Type Manager, which allowed Postscript fonts to
be scalable on screen and to be printed on non-Postscript printers. They
also published the Postscript font format specifications which allowed
others to create Postscript fonts.
Apple eventually reached an agreement with Adobe to continue to use Postscript
fonts in their printers. Meanwhile, Microsoft added TrueType fonts to
the Windows 3.1 operating system and contracted with Monotype to create
high quality TrueType fonts that were compatible with the basic fonts
used in Postscript laser printers.
OpenType was originally developed by Microsoft and they were later joined
by Adobe. OpenType is intended to be the successor to both the Postscript
and the TrueType font formats. OpenType fonts began shipping in 2000,
and Adobe finished converting its entire font library to OpenType by the
end of 2002.
OpenType fonts come in two "flavors." OpenType fonts with the
.otf file extension use the Postscript outline format. OpenType fonts
with the .ttf file extension use the TrueType outline format.
One of the most attractive things about OpenType, from a design standpoint,
is the ability to access advanced typographic features like ligatures,
old-style numerals, fractions, and true small caps in one font. Before
OpenType, these features were only available in "expert sets."
These were separate font files from the normal fonts.
