Braille—A form of tactile signage consisting of raised symbols that enabling visually-impaired and unsighted people to read and write. Braille is broken into two grades: Grade 1 Braille involves a character-by-character translation of printed material; Grade 2 Braille uses special contractions (much like the phonetic parts of speech) for messages. Grade 2 Braille is required by federal law according to the Americans with Disabilities Act (ADA). Brightness—A measurement of the refl ective quality of a medium such as paper or vinyl. Different brightness levels can cause changes in the appearance of color on the medium, and may require printer adjustment. Broadcast—A type of connection in which network manager sends information to many media players all at once, rather than making a separate connection to each player one at a time. Broadcast Folder—A folder on the broadcast server machine in which published fi les are received for subsequent broadcast transmission. Broadcast Server—A machine that prepares and transmits broadcast fi les received from a network manager machine. Also may refer to the broadcasting software that runs on this machine, or the network manager defi nition of the machine's location. Browser—Software for viewing Web sites, HTML fi les, and related content, such as Microsoft Internet Explorer. Bulletin Colors—Specially prepared enamel paints preferred by many sign painters for hand- lettering. Burning-In—Recommended to bring a neon tube to its proper brilliance, burning-in involves connecting the completed tube to a transformer similar to that which will be used in the installation and allowing it to remain lighted until proper brightness, color and electrical properties are achieved. Also called aging. Burnish—To polish by rubbing, a common practice in the gilding process. Bushing—In a neon sign, insulates the electrode from a metal sign. Requires a separate connection between the electrode and the high-voltage line. Byte—The basic unit of computer storage, comprising eight bits. Typically, a byte can store one character of text, or one pixel. C Cabinet—An electric sign, not including the components and structure. A cabinet is made up of a face and back, or two faces, along with the edge. Also called "can". CAD (Computer-Aided Design)—The use of computer programs and systems to design detailed two- or three-dimensional models of physical objects, such as mechanical parts, buildings, and signs. Calendered Vinyl—Vinyl sheeting squeezed between a series of heated rollers (also extruded) to achieve a small-enough thickness for cutting with a knife plotter. Calendered fi lm is generally thicker and less expensive than cast vinyl. Calibration—Operation of matching color shades and hues between any input devise(design software/monitor/scanner/camera) and output device (printer). Also the operation of keeping colors consistent during printer operations, compensating for changes in humidity, media, toners, etc. CAM (Computer-Aided Manufacturing)— The process of using specialized computers to control, monitor, and adjust tools and machinery in manufacturing. Candela—A unit of measure indicating the amount of intensity displayed by artifi cial light. Abbreviated as cd. Capacitor—An electric circuit element used to store charge temporarily, consisting in general of two metallic plates separated and insulated from each other by a dielectric. Also called condenser. Captive Audience Networks—A captive audience network is a digital advertising media network installed where your target audience is assured to remain in place for a period of time. Typical captive audience networks are installed in supermarket queues, gas station pumps, banks, and wherever people gather and wait. Carrier—Substance in which pigments in inks are suspended. Aqueous, solvent and eco-solvent SIGN & DIGITAL GRAPHICS carriers evaporate after printing. Monomers are considered carriers in UV-curing inks, but are transformed into solid polymers after curing. Carrier Sheet—Generally, a backing material used to temporarily hold or protect another material. Cast Acrylic—Acrylic sheet produced by pouring acrylic resins into a mold and allowing them to cool. (See also Extruded acrylic). Yields best results from laser engraving. Cast Vinyl—A type of vinyl fi lm formed by spreading a molten plastic mixture on a carrier sheet in a thin layer, and then baking at high temperatures to remove solvents and fuse the remaining material into a fi lm. Cast fi lm is usually thinner, more pliable and more-expensive than calendered vinyl. Casting—A method for mass-producing objects such as sculptures, letters, embellishments or individual signs by pouring liquid material into a prepared mold. CAT5 Cable—A data and communications cable adopted by the Telecommunications Industry Association (TIA) and International Standards Organization (ISO). This version of Category 5 uses all four pairs of wires to both send and receive. Cationic UV-Curing—A form of UV-curing ink chemistry. Cationic inks are said to adhere to an extremely wide range of substrates. Unlike free radical UV-curing, with cationic UV curing the cure reaction continues to completion even after exposure to UV energy has ceased. CCD (Charged Couple Device)—A device made up of semiconductors arranged in such a way that the electric charge output of one semiconductor charges an adjacent one. The light-sensitive element inside many fl atbed scanners. CCD-based scanners typically have 1,000-7,000 elements. Channel—In electronic digital signage, a channel is a script that has been published in such a way that when its contents change, the updated material is forwarded to machines running the viewer that have subscribed to the channel. Channel Letter—The outline of a letter, with extended sidewalls that create depth, into which a light source is placed. GLOSSARY
