shades per primary color (See RGB). Considered one of best ways to compare true ability of a scanner, although not all manufacturers measure and release figures on it. Dynamic Visual Messaging—The process of using animated graphic design to communicate to target audiences through signs and public displays. E Eco-Solvent Inks—Inks using a less-toxic solvent-based carrier. Printers using eco-solvent inks emit less harmful VOCs (volatile organic compounds). Edge—The part of the sign that encloses the back and face or faces. The frame. Electrostatic Printer—A printing device based on xerography (the technology used in most photo copiers). Electrostatic printers (also called e-stat) transfer toner resins or dyes from an electrically charged plate or writing nib to a substrate, then thermally sets them. Electronic Kiosks—Terminals that disseminate information and services to the public through touch-screens and video displays. Electronic kiosks are often built by display companies and customized to individual needs by multimedia developers and value added resellers. They often incorporate card readers, coupon printers, and other devices specific to their application. Embellishments—Elements added to a sign face for aesthetics and visibility. Cut-outs, pushthroughs, neon strips and clocks are all examples of embellishments. Event—An action in a script; virtually everything that happens in a script is an event, including text, sounds, wipes, animations, etc. Expanded-Gamut Color—A system in which additional colors (usually light cyan, light magenta, light yellow, light black, green and/or orange) are used to supplement CMYK, in order to reproduce a greater number of colors. See also Hexachrome, hi-fi color. Extender—Added to an ink to improve its working quality or for extending the volume. Exterior Illumination—Illumination that is provided from a source separate from the sign itself, such as a spotlight. Also called indirectly illuminated. Electrolytic Capacitor—A type of capacitor that has a lot of capacity for its size and price. It contains an electrolyte than can dry out over time and that in turn decreases its capacity. Every 10C increase in operating temperature reduces the rated life of the capacitor by half. A 20C high temperature decreases life to 1/4. Emboss—The process of producing raised letters, particularly those produced by engraving dies or plates. Extruded Acrylic—Acrylic produced by forcing acrylic resins through a specifically shaped die (see also Cast Acrylic). Usually avoided by laser engravers since it cuts well with a laser engraver but does not engrave well. Emulsion—A semi-liquid material that dries hard and is used in preparing stencils used in screen printing. Extrusion—A part created by forcing a raw material (usually metal or plastic) through a die to create a specific shape. Enamel—a type of paint, usually opaque, that dries to a hard glossy finish. F Electronic Digital Signage—A form of signage using plasma display panels (PDPs), liquid crystal displays (LCDs), light emitting diode signs (LEDs), and/or television (CRTs) in place of traditional signage. Content can be instantly updated, and multiple screens can be networked and managed from a single location. Enclosure—A piece of equipment which houses the components, such as a monitor or display, and in some cases a computing device and/or other option peripherals devices such as printers, keyboards, etc. Electrode—A terminal that conducts an electrical current between two conducting substances. Electrodes are found at both ends of a neon unit. Electronic Digital Signage Network (DSN)—Delivery system for retail media, outdoor advertising and placed-based television content in public spaces, consisting of displays, software and hardware tied together through a computer network infrastructure. (Also known as dynamic digital signage; digital sign system, etc.) Electronic Display—A general term referring to any type of electronic programmable display. Electronic Message Center (EMC)—A sign that utilizes computer-generated messages or some other electronic means of changing copy. These signs include displays using incandescent lamps, LEDs, LCDs or a flipper matrix. Also called changeable message signs (CMS). Electrostatic Film—Vinyl film treated with a small charge of electricity, enabling it to temporarily, but firmly, adhere to glass and similar smooth substrates. Engraving—Method of marking metal, plastic or glass in shallow, negative relief utilizing a bit or graver. Engraving may be done freehand, using a pantograph or computer-driven equipment. EPS (Encapsulated PostScript)—File type that allows different information, such as colors and fill patterns, to be carried between software programs. Files can include bitmap and vector information, including low-resolution files for thumbnail previews. Versions of this include variations from Adobe Illustrator (with .AI filename extensions for DOS and Windows). Equalization—A processing technique where the range of colors in a file is expanded to produce a better image. Error Diffusion—Process where equal-size dots are placed, via computer calculation, based on an image's detail and tones. The result is a continuous tone image. Facade—The front or principal entrance of a building. Face—The decorated surface of a sign; the area on which the copy and art is placed. Fiber Optic Display—A type of sign that transmits its message utilizing light directed through fiber optic cable. File Compression—The process of condensing a file, video, or animation using special hardware and/or software so that it requires less storage space. In color management, the ability of a software to reduce the range of colors in an image to whatever can be reproduced on an output device is called "compression". Fills—Tool-path directions and methods for traveling through substrate to remove, or rout, material. Sweep or hatch fills remove material in consecutive, side-by-side lines; spiral fills trace the edge of area of material to be removed, then work inward to center in one path; island fills trace the edge, then work inward in separate, concentric paths. Flasher—A mechanical device designed to interrupt the electrical current in a sign at regular intervals, turning the light source on and off to create a flashing image.
