Xerox 2000, Owner'S Manual, Page: 180 / 192

Bleed An image that extends to all four edges of a page. The extra amount of
the image that is printed on a sheet beyond the crop marks (the sheet
is then trimmed to size).
Calendered Paper that has been passed through a series of stainless steel rollers
that produce a very smooth finish to the paper.
Calibration A procedure to set equipment (such as displays, printers, presses, and
scanners) to a standard level to ensure predictable results.
Caliper The thickness of a sheet of paper, measured in microns.
Chalking Pigment dusts off of prints because the ink was absorbed too rapidly
into the paper (when printing on an offset press).
Choke A form of trapping. A choke traps a light background to a dark
foreground. The lighter colour is spread inward slightly into the darker
colour to maintain the visual edge. See also spread.
Chroma The vividness or dullness of a hue. One of the three characteristics that
describe colour (along with hue and value). Also called saturation.
CIELAB A device-independent colour space in which three variables (L*, a* and
b*) are used to describe a colour. L* represents lightness, and the
chromatic axes are a* (the red/green axis) and b* (the yellow/blue
axis). CIELab defines the largest gamut or colour space.
CMM Short for Colour Matching Module. A part of the colour management
system that connects together profiles to produce colour transformations
for a group of devices.
CMS Short for colour management system.
CMYK Short for cyan, magenta, yellow and black – the four printing, or
process, colours. They are the three subtractive primaries (cyan,
magenta and yellow), as well as black, used to enhance colour and
improve contrast.
Coated Paper that has additional pigments and binders added to enhance the
surface quality and printability of the stock.
Collate The ability of the printing press to assemble sheets in the correct order.
Collating The process of gathering signatures together so that page 1 is followed
by page 2, page 3, and so on.
ColorSync The colour management framework that is used in the Macintosh
environment.
Colour management
system
A software system that controls the transformation of colour values of
different devices to ensure consistent results between different devices.
Profiles are generated for input devices (like scanners and digital
cameras), displays, and output devices (like printers and presses). These
profiles tell the conversion routines of the colour management system
how to convert the colour values of one device to another.
