A system in which colors are produced by combining red, green, and blue light (the
additive primaries). An RGB video monitor is based on an additive color model.
additive primaries
Red, green, and blue light used in additive color systems. When blended together in
proper amounts, these colors of light produce white.
artifact
A visible defect in an image, usually caused by limitations in the input or output process
(hardware or software); a blemish or error.
banding
Visible steps between shades in a color gradient.
bit depth
Amount of information used for each pixel in a raster image. Black and white images
require only one bit per pixel. Grayscale images with 256 shades of gray require 8 bits (or
1 byte) per pixel. Photographic quality color images can require 24 bits per pixel (RGB
images) or 32 bits per pixel (CMYK images).
bitmap (or raster)
An image comprised of small squares arranged in a grid. Each square in the grid is a
pixel. The number of pixels per inch defines the resolution of a bitmap.
blasting
An undesirable effect that occurs when excess amounts of toner, possibly combined with
certain types of paper stock, cause objects in an image to spread beyond the boundaries
defined in the file.
BMP
A graphics file format established by Microsoft; native to the Windows operating system.
calibration

specifications.
