Adobe Type Manager (ATM) is a font management tool available for both
Mac OS and Windows, and produced by Adobe.
ATM provides:
* Font substitution, to use a similar font when font that's not
installed is requested.
* PostScript Type 1 font scaling (both on-screen, and for non-
PostScript printers or QuickDraw printers).
* Type smoothing (antialiasing), including on-the-fly when an
installed font's matching screen font is not present.
Anti-aliased text appears smoother on screen, and can more closely
resemble that actual letter shapes. To avoid jagged text or distorted
letter shapes, it's especially important to antialias text on the low-
resolution colour and greyscale screens that were common before
"Retina" and other fine-point displays became common.
After the introduction of ATM Deluxe, ATM became the freeware ATM
Light, smoothing the on-screen appearance of Type 1 and OpenType
fonts, and performing font substitution when documents require fonts
that aren't installed.
Note: PostScript font support is built into Mac OS X and Windows 2000
and XP, so ATM isn't necessary for basic font usage. ATM Light is
required for all other versions of Mac OS, including Mac OS X's
Classic mode, as well as for previous versions of Windows. It is also
required for Windows 2000 if you use Adobe's multiple master typefaces
and want to create custom fonts.
