Positive kerning or tracking values
move characters apart; negative kerning
or tracking values move characters
closer together. Kerning and tracking
values are measured in units that are
1/1000 of an
em space . The width of an
em space is relative to the current type
size. In a 1-point font, 1 em corresponds
to 1 point; in a 10-point font, 1 em cor-
responds to 10 points. Because kerning
units are 1/1000 em, 100 kerning units
in a 10-point font are equivalent to
1 point.
