B. Glossary Of Color Management Terms Absolute Colorimetric Associations Calibration CIELAB CMYK Coated Color Cast Colorimetric Contrast A rendering intent that maps colors to the nearest hue based upon a perfect illuminant. When printing using this intent, highlights tend to be washed out and colors appear lighter. The DocuSP controller uses stock associations to create color groups of similar stocks that can use a single calibration. Once a stock is associated with a color group, it 'inherits' attributes from the group. Calibration is a process that enables the user to measure the printer's output against a known standard, by using a Spectrophotometer to scan test patterns. The process enables the user to adjust for "drift" in the color response of the printer and achieve consistent results. A standard color space model defined by the Committee Internationale de l'Eclairage, an international standards committee. L*A*B* is a color space that describes color in terms of human eye response. A color space model that defines the relative amounts of Cyan, Magenta, Yellow, and Black toner or ink that will be applied to the print. CMYK can be found in both input and output profiles. Coated refers to whether the stock in use has been coated or was left uncoated. Generally, prints on coated stock will appear glossier than do prints on uncoated or matte stocks. This visual color difference may not be measurable, but it exists. The technical term for an overall color imbalance affecting an entire image. The DocuSP controller enables you to adjust the color cast in order to balance the image. Refers to mapping an output color directly to the input color. In display systems, the relation between the intensity of color, brightness, or shading of an area. High-contrast images have darker shadows and brighter highlights, while low-contrast images have lighter shadows and duller highlights. Color Management Guide B-1
