color spaces hp designjet 5500 series welcome how do I ... tell me about ... the problem is ... legal notices glossary index color spaces These color spaces are described: q RGB q LAB q CMYK RGB The additive color primaries are red, green and blue. Together they make 'white', which varies considerably with the type of illumination and the ratio of the primaries. Light behaves in an additive manner, as do computer monitors and other color displays. Scanners and digital cameras use red, green, and blue sensors to separate images into their component colors. Additive color describes the color of light. Combined in pairs, the colors created are yellow, cyan and magenta. Combining the three primary colors creates white light. LAB Short for CIELAB, this color space is used for color calculations in color management systems. CIELAB has the advantage of being 'perceptually uniform', which makes mathematical calculations more efficient. It is possible to convert and save images in LAB color, and some scanners produce images in LAB color. file:///C|/Documents%20and%20Settings/---/Desktop/HP/html/C000-63.htm (1 of 3) [8/5/2002 2:20:38 PM]
