Look-up table (LUT)
A negative or positive image whereby detail of the image is
reproduced with dots varying area but of uniform density. Creates the
illusion of continuous tone when viewed with the naked eye.
The whitest portions of the original or reproduction that have no
color cast. The highlight dot is ranged in the reproduction from the
smallest printable dot to approximately 25%. See also Midtones and
Shadows.
Abbreviation of Hue, Saturation and Lightness. This is a color model,
which specifies a color by its wavelength (Hue), chroma or purity of
the color (Saturation) and value of its brightness (Lightness).
Portion of a negative or plate corresponding to inking on paper. The
portion of paper on which ink appears.
The arranging of pages in a press form to ensure the correct order
after the printed sheet is folded, bound and trimmed.
A proof of a digital image printed by using jets that squirt minuscule
drops of ink. Ink jet proofers can print onto a variety of surfaces.
Job flow refers to the job parameter settings of selected virtual
printers that are automatically applied to all jobs printed using that
virtual printer. These settings determine how a sent or imported file
is processed. For example, a file sent to a virtual printer with a Process
& Print job flow will be RIPped, printed and stored in the Storage
Folder. A file sent to a Process & Store job flow virtual printer will be
RIPped and stored, without printing.
A printer page orientation, where pages are delivered long edge first.
A part of the Macintosh system software which generates PostScript
instructions from an application file when the Print command is
activated.
A two or three-dimensional array of values stored for specified input-
output relationships. When one input value is known, the system can
automatically determine the correct output value. For example, the
system can find the needed 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 are one of the many
kinds of LUTs.
