4 bump map
"A set of per-pixel color and luminance data used to simulate relief, detail, or texture (bumps) on the surface of a graphic object without modifying the geometry of the object model." -
5 color space
"The three-dimensional space that is defined by a set of coordinates for representing color on devices such as monitors, scanners, and printers. For example, in the LAB color space, the colors are defined in terms of their luminance or whiteness (L), redness-greenness (A), and yellowness-blueness (B); the HVC system uses hue (H), value (V), and chroma (C). The two most common color space models are RGB and YUV." -
6 color space model
"The three-dimensional space that is defined by a set of coordinates for representing color on devices such as monitors, scanners, and printers. For example, in the LAB color space, the colors are defined in terms of their luminance or whiteness (L), redness-greenness (A), and yellowness-blueness (B); the HVC system uses hue (H), value (V), and chroma (C). The two most common color space models are RGB and YUV." -
7 YUV color space
"A color model that describes color information in terms of its brightness (luminance, or Y), and color (chrominance, or U and V)." -
8 YUV
"A color model that describes color information in terms of its brightness (luminance, or Y), and color (chrominance, or U and V)." -
9 HSL
"A color model that defines a color by three values: Hue, the color itself; Saturation, the purity of the color; and Luminance, the amount of light that is either reflected or absorbed by the color." -
10 centerline trap
The small overlap created where two differently colored objects that are close in luminance abut on a printed page.
