color depth
The maximum number of colors an image can contain. Color depth is determined by the bit depth of an image and the displaying monitor.
For example, an 8-bit image can contain up to 256 colors, while a 24-bit image can contain roughly up to 16 million colors. A GIF image is
an example of an 8-bit image; a JPEG image is an example of a 24-bit image.
CMY
A color mode made up of cyan (C), magenta (M), and yellow (Y). This mode is used in the three-color printing process.
CMYK
A color mode made up of cyan (C), magenta (M), yellow (Y), and black (K). CMYK printing produces true blacks and a wide tonal range. In
the CMYK color mode, color values are expressed as percentages; therefore, a value of 100 for an ink means that the ink is applied at full
saturation.
code page
A code page is a table in the DOS or Windows operating system that defines which ASCII or ANSI character set is used for displaying text.
Different character sets are used for different languages.
color channel
An 8-bit grayscale version of an image. Each channel represents one level of color in the image; for example, RGB has three color channels,
while CMYK has four. When all the channels are printed together, they produce the entire range of colors in the image.
See also RGB and CMYK.
color gamut
The range of colors that can be reproduced or perceived by any device. For example, a monitor displays a different color gamut than a
printer, making it necessary to manage colors from original images to final output.
color mode
A system that defines the number and kind of colors that make up an image. Black-and-white, grayscale, RGB, CMYK, and paletted are
examples of color modes.
color model
A simple color chart that defines the range of colors displayed in a color mode. RGB (red, green, blue), CMY (cyan, magenta, yellow), CMYK
(cyan, magenta, yellow, black), HSB (hue, saturation, brightness), HLS (hue, lightness, saturation), and CIE L*a*b (Lab) are examples of color
models.
color palette
A collection of solid colors from which you can choose colors for fills and outlines.
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 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.
