used to seal holes in the stencil in areas not intended to be screen printed. Bombarding—The process of heating the glass and metal portions of a neon tube to a high temperature to release all absorbed gases and other impurities. Bonderized—A process where sheet metal is zinc-coated, then treated to allow for paint to adhere. Used in creating baked enamel signs. Bounding Box—The area of an on-screen image at its maximum X and Y axes measurements. Altering the bounding box by moving its control points can change the shape or size of an image. Bounding boxes allows scaling of all graphics images in PostScript file types. necting 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 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  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 film 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 film. Cast film is usually thinner, more pliable and more-expensive than calendered vinyl. 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). 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. Casting—A method for mass-producing objects such as sculptures, letters, embellishments or individual signs by pouring liquid material into a prepared mold. Brightness—A measurement of the reflective  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. 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 film is generally thicker and less expensive than cast vinyl. 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. 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. 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. 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. CAM (Computer-Aided Manufacturing)—The process of using specialized computers to control, monitor, and adjust tools and machinery in manufacturing. 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 flatbed scanners. CCD-based scanners typically have 1,000-7,000 elements. Broadcast Folder—A folder on the broadcast server  machine in which published files are received for subsequent broadcast transmission. Broadcast Server—A machine that prepares and transmits broadcast files received from a network manager machine. Also may refer to the broadcasting software that runs on this machine, or the network manager definition of the machine's location. Browser—Software for viewing Websites, HTML  files, 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 con- Candela—A unit of measure indicating the amount of intensity displayed by artificial 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. 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.
