Character Generator—A device for creating text on video. Character generators are often used to make information channels and electronic bulletin boards for TV and Cable. Chase—The illusion of movement in neon tubes or incandescent bulbs created by turning the light sources on and off in sequence. Also, to decorate metal, typically by engraving or cutting. Chromaticity—The quality of a color as determined by its purity and dominant wavelength, which is relative to saturation and hue, as used in the HSV model. Chrome—High-quality positive color fi lm, ordinarily shot by professionals. It includes 35-mm slides, 2 1/4" x 2 1/4" medium-format fi lm and 4" x 5" view-camera transparencies. Chrome positives are often used for proofi ng. Chrominance—The property of a color that describes its saturation, intensity, or colorfulness, used in differentiating two colors of equal brightness and hue. CIE (Commission Internationale de l'Eclairage)—A color-standards organization based in Vienna, Austria. The CIE's chromaticity diagram is a two-dimensional reference for defi ning colors and color spaces based upon physiological measurements of human color vision. An abbreviation for the CIE L*a*b* (CIELAB) color space. Cladding—Cover material applied over the framework of a structure. Classic Glass—Tubing used for neon signs or artwork in which the glass itself is colored achieving a deep, saturated color not possible with clear glass and phosphor coatings; typically a soda-lime based glass. Clip—A predefi ned graphic image, such as a picture, drawing, symbol, etc., that can be imported and positioned on a background. Clip Art—Ready-made, royalty-free pieces of printed or computerized graphic art. Clogging—The result of dried ink molecules in an inkjet printhead.

Coat-Out—To paint the surface before the art is applied. Codec—A software module responsible for compressing and/or decompressing an encoded media format such as AVI digital video. Cold Cathode—The technical name for all forms of neon lighting. The term "cold cathode" is used to refer to 18mm to 25mm tubing operating at currents 60mA to 240mA. These gas discharge lamps also have electrodes that depend on a large emission surface area rather than high temperature for their operation. Color Calibration—Hardware and/or software that allows a color match to be made between multiple digital devices. Color Curve—Visual control used in photo- illustration and other graphics software to display color measurements and make tonal changes to an image.
