Roman Baseline Leading occurs based on the Roman Baseline. Leading is measured from the baseline of the current
line to the baseline of the previous line. This leading method is the same as that which is used in the Roman composer.
The Roman Baseline is different for each font. The character position may vary even within the same font size if the
fonts are different.
Embox Bottom/Left Leading occurs based from the bottom of the embox for horizontal type or from the left of the
embox for vertical type. Leading is measured from the left or bottom of the current line to the left or bottom of the
previous line.
Note: The same item is present in Grid Alignment in both the Paragraph panel menu and in the Control panel menu. These
items are the bases for aligning to the grid, and not bases for leading. Do not confuse these.

Kerning and tracking
About kerning and tracking
Kerning is the process of adding or subtracting space between specific pairs of characters. Tracking is the process of
loosening or tightening a block of text.
Note: Values for kerning and tracking affect Japanese text but normally these options are used to adjust the aki between
roman characters.
Types of kerning
You can automatically kern type using metrics kerning or optical kerning. Metrics kerning uses kern pairs, which are
included with most fonts. Kern pairs contain information about the spacing of specific pairs of letters. Some of these
are: LA, P., To, Tr, Ta, Tu, Te, Ty, Wa, WA, We, Wo, Ya, and Yo.
InCopy uses metrics kerning by default so that specific pairs are automatically kerned when you import or type text.
To disable metrics kerning, select "0".
Optical kerning adjusts the spacing between adjacent characters based on their shapes. Some fonts include robust kern-
pair specifications. However, when a font includes only minimal built-in kerning or none at all, or if you use two
different typefaces or sizes in one or more words on a line, you may want to use the optical kerning option.
Optical kerning adjusts the spacing between adjacent characters based on their shapes, and is optimized for use with
Roman glyphs. Some fonts include robust kern-pair specifications. However, when a font includes only minimal built-
in kerning or none at all, or if you use two different typefaces or sizes in one or more words on a line, you may want to
use the optical kerning option for the Roman text in your document.
