Xerox manual DocuColor 2000 series design guide, Bleed

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.
