Lab (CIE L*a*b): A color model created
by the Commission Internationale de l'Eclairage (CIE).
It contains a luminance (or lightness) component (L)
and two chromatic components: "a" (green
to red) and "b" (blue to yellow).
Lap register: used with knockouts,
images of different colors are slightly overlapped,
to avoid the appearance of a white line between
the two inks.
Leader: a line of dots or dashes
to lead the eye across the page to separated copy.
Leader tabs: A row of characters
placed between text objects to help the reader follow
a line across white space. Leader tabs are often
used in place of tab stops, especially before text
that is flush right such as in a list or table of
Leading: (pronounced "led-ding")
the space between lines of type, traditionally measured
baseline-to-baseline, in points. Text type is generally
set with one or two points of leading; for example,
10-point type with 2 points of leading. This is
described as 10/12, read ten on twelve.
Letterforms: in typography, the
shapes of the characters.
Ligature: in typography, characters
that are bound to each other, such as "oe"
and "ae." In professional typefaces, the
lowercase "f" is also often set as a ligature
in combination with other characters such as "fi"
Light (font): a font that is lighter
than the roman (normal, plain, or book) version
of the typeface.
Line art: black-and-white artwork
with no gray areas. Pen-and-ink drawings are line
art, and most graphic images produced with desktop
publishing graphics programs can be treated as line
art. For printing purposes, positive halftones can
be handled as line art.
Logotype: a symbol, mark, or identifying
LZW: A lossless file compression
technique that results in smaller file size and
faster processing time. LZW compression is commonly
used on .gif and .tiff files.
