B-6
gray scale
A range of grays with regular density intervals from white to
black. A gray-scale image is an image that contains various levels
(or shades) of gray.
halftone
A technique used to reproduce a continuous-tone original, such
as a photograph. The printing press prints a matrix of miniature
dots of varying size, or lines of varying thickness. A limited set
of inks (for example, only black ink or CMYK inks) can thus give
the naked eye an illusion of many shades of gray or many colors.
hard copy proof
Color printer output used to verify the colors and layout of an
image or document.
highlights
The brightest areas in an original or an image, represented in a
halftone by the smallest dots or the absence of dots. The dot area
of highlights ranges from 0% to about 20%. Compare with
shadows.
hue
Color, the main attribute of a color that distinguishes it from
other colors.
image
The bitmapped result of scanning an original. Compare with
original and reproduction.
input resolution
The resolution at which a scanner scanned an image, expressed in
pixels per inch. See also ppi.
International Color Consortium (ICC)
An international consortium that defines the color profile format
or standards for a multi-vendor, multi-platform application.
Lab
The CIE L*a*b* is a perceptually uniform color space proposed
by the CIE for use in the measurement of small color differences.
