L*a*b*
A device-independent color measurement system that measures
Lightness (or Luminance) and two color coordinates, A (red/green)
and B (blue/yellow). It may be used as an intermediate color space
used when converting from one color space to another (for
example, from CMYK to RGB).
line work
Data characterized by sharply defined lines and very clear
transitions from one color to another—for example, text. Line work
is stored in the computer as a series of geometric (vector) drawing
instructions.
long-edge first (LEF)
A printer page orientation where pages are delivered to the printer
with the long edge of the paper going in first.
lookup table (LUT)
A two or three-dimensional array of values that stores information
about specified input-output relationships. When an input value is
known, the system can automatically determine the correct output
value. For example, the system can find the required dot size for a
given set of printing conditions based on the stored gray level.
Color setups can be saved in color tables (color transformation
tables), which is one of the many kinds of LUTs.
