Multiple Master Fonts
585
In MM fonts it is important to know how much the property connected
with the design axis can be changed. If we take the Weight axis, for
instance, then it might be changed from normal (120) to bold (700), a
moderate change, or from light (50) to black (1450), a much larger change:
50
120
1450
700
The range within which the property of the axis may be changed is called
the dynamic range. It is the distance between the two masters that define
an axis measured using a standard scale line.
In our example the first dynamic range is 580, from 120 to 700, and the
second dynamic range is 1400, from 50 to 1450.
So that desktop publishing programs can use MM fonts that were designed
by different manufactures some standards have been set for axes types and
names.
