Microtype Express

A technology developed by AGFA for compressing TrueType font data, used for the *EOT files in Internet font embedding. AGFA describe Microtype Express here.

multiple masters

These are Type 1 fonts capable of producing a continuous range of type designs. In effect, a multiple master font is a whole family of type - where all the "in-between" typefaces are available to the font user. MM fonts have from 1 to 4 *design axes, most often weight (from light to bold), width (from condensed to expanded) and optical size (from 6pt to display). But a type designer could propose any axis where the extremes are made by moving the same set of outline points. Because you need a master at each extreme, multiple master fonts have 2, 4, 8 or 16 masters for each glyph. Adobe has a multiple masters webpage.
    *OpenType fonts, in their Type 1 flavour, can be multiple master fonts.
    If you're creating multiple masters, *FontLab has a far better interface and is more reliable than *Fontographer.
    The TrueType equivalent of multiple masters, only available on the Macintosh, is GX font *variations.
