color space array (CSA)

A three-dimensional or four-dimensional lookup table that contains
data for translating a device-dependent color space into a device-
independent L*a*b* color space.

composite mode

A mode of operation in which all the color information associated
with a particular page is described on one page of a PostScript
file. During RIP, the file is separated into process colors and spot
colors, one file for each color. This mode of operation is the fastest
and most efficient in most cases.

contrast

The ratio between the light tones and the dark tones in an image.
If you increase the contrast, highlights become lighter while
shadows become darker.

conventional screening

A method of screening in which an image is broken down into a
series of dots of varying sizes that are placed in a rigid grid
pattern. Color images are separated into the four process colors,
and individual screens of color are created and then skewed at
angles to reproduce the image in print.

creep

The extension of middle pages of a folded signature slightly
beyond outside pages. Shingling compensates for creep.

CT file format

A four-color (CMYK) continuous-tone (or contone) raster file
format. Gradient tones and continuous-tone data are sometimes
converted to CT format.
