color profile
A description of the color-handling capabilities and characteristics of a device.
color separation
In commercial printing, the process of splitting colors in a composite image to produce a number of separate grayscale images, one for each
primary color in the original image. In the case of a CMYK image, four separations (one for cyan, magenta, yellow, and black) must be made.
color space
In electronic color management, a virtual representation of a device or the color gamut of a color model. The boundaries and contours of a
device’s color space are mapped by color management software.
See also color gamut.
color swatch
A solid-colored patch in a color palette.
color tolerance
The value that determines the color range or sensitivity of the Lasso mask tool, Magic wand mask tool, and Fill tool. Tolerance is also used in
the Color mask dialog box to determine which pixels are protected when you create a color mask. A pixel is included in the specified color
range if its grayscale value falls within the defined tolerance.
color trapping
A printing term used to describe a method of overlapping colors to compensate for misaligned color separations (misregistration). This
method avoids white slivers that appear between adjoining colors on a white page.
See also spread, choke, and overprinting.
contrast
The difference in tone between the dark and light areas of an image. Higher contrast values indicate greater differences and fewer
gradations between dark and light.
control points (Corel PHOTO-PAINT)
The points that extend from a node along a curve that is being edited with the Shape tool. Control points determine the angle at which the
curve passes through the node.
crop
To cut unwanted areas of an image without affecting the resolution of the part that remains.
cubist
An abstract style of art that stresses several aspects of the same object simultaneously, generally in the form of squares or cubes.
D
DeviceN
A type of color space and device color model. This color space is multi-component, allowing color to be defined by other than the standard
set of three (RGB) and four (CMYK) color components.
distortion handles
The outward-facing, double-headed arrows located at each corner of the highlighting box.
dithering
A process used to simulate a greater number of colors when only a limited number of colors are available.
dpi (dots per inch)
A measure of a printer’s resolution in dots per inch. Typical desktop laser printers print at 600 dpi. Imagesetters print at 1270 or 2540 dpi.
Printers with higher dpi capabilities produce smoother and cleaner output. The term dpi is also used to measure scanning resolution and to
indicate bitmap resolution.
