Terms of the Trade MEMS (Micro Electro-Mechanical System)—A manufacturing process done on an extremely small scale (typically involving components between 1 to 100 micrometers in size). In inkjet technology MEMS uses laser systems to cut and shape silicon to create printhead components such as jetting chambers, nozzles and nozzle plates. Typically, MEMS-based printheads feature more nozzles per inch and greater jetting accuracy. Menu Board—A changeable point-of-purchase advertising display that allows the retailer to list products and prices. Mercury—A heavy, silver-white metallic element liquid at room temperature. In neon tube processing, it may be mixed with rare gases, typically argon, to produce ultraviolet light. Mesh—In screen printing, the material stretched across the frame. Also referred to as the fabric. Message Center—Any sign that displays changeable copy through electronic or mechanical means. Message Controller—In an electronic sign, the device that stores messages and conveys them to the display area. Mercury Arc Lamp—A special lighting system designed to produce high levels of ultraviolet (UV) light in order to cure UV-curable inks. Most commonly used technology in UV-curing inkjet printers. Metamerism—In color matching, a characteristic of prints in which color matches under one lighting condition, but not another. Microprocessor—The main computing, or thinking chip in a computer. Micro-Stepping—Process of moving media through a printer in smaller-than-standard motions. Can improve dot gain and density when printing solid areas on film positives. Mild-Solvent Inks—Also known as "light solvent" inks, these use cyclohexanone, the same carrier employed in solvent inks, but in greatly reduced concentrations. Printers using mild-solvent inks employ additional carriers and emit fewer harmful VOCs than standard solvent inks. Mirror/Mirror Print—Function of reversing type or an image to be printed. Used mainly for cutting jobs to be installed on the inside surface of a transparent substrate (such as a window). Often used in digital imaging as part of a process wherein a reversed image is applied to a transfer paper used in dye-sublimation transfer printing. 112 • Mid-June 2013 • S I G N SBGuide.indd 112 Moiré Pattern—A visual defect that occurs when the dots of the different separations used to create a halftone image are unevenly spaced, conflicting or have overlapping angles. Visual artifacts occurs between the dots of the different separations in the halftone images. Monomer—A chemical compound ingredient in UV-curing inks that, when combined with other similar structures and oligomers and exposed to UV radiation, undergoes the process of polymerization and is transformed from a liquid (monomer) to a solid (polymer) state. Monument Sign—A free-standing sign sitting directly on the ground or mounted on a low base. MovieClip—a digital video segment in an ActiveMovie-supported format, such as AVI, QuickTime, or MPEG, that has been loaded as a clip. Movieclips are similar to AnimClips except that they can also have sound associated with them. Movieclips cannot have their frame rate or color palettes adjusted. MPEG (Motion Picture Experts Group)—An industry group that developed a standardized form of file compression for digital video and audio sequences. MPEG digital video sacrifices some image quality to achieve very high compression. MPEG-4—An updated file compression standard developed by MPEG which brings higher levels of interaction with content, controlled by the content developers. It also brings multimedia to new types of networks, including those employing relatively low bitrates, and mobile ones. Multi-Color Printing—Any screen printing job involving the application of more than one color of ink. Multimedia—The combination of various presentation media such as text, sound, graphics, animation, and video. Multimedia Displays—TVs, plasma display panels,  LCDs  or other video display device delivering  multimedia content, often connected to a computer and touch screen. Multimedia Signs—Multimedia signs are a growing trend in the signage industry, where televisions or flat panel display devices such as plasma screens or liquid crystal displays, are turned into updatable signage. Advantages of multimedia signs include the ability to deliver messaging to targeted audiences depending on schedule or environmental conditions. For example, advertise umbrellas when it's raining. N Narrowcasting—Delivers highly targeted and customized messages to audiences in public locations at scheduled times. Usually, this is accomplished with a networked multimedia system allowing rapid production, customization, distribution, and playback to multiple locations on display devices such as televisions and liquid crystal displays. The advantages of narrowcasting over traditional media include lower production costs, greater flexibility, and more attention-grabbing visuals. Narrowcasting Networks—Narrowcasting  networks reach targeted portions of the public. They employ selective broadcasts of media-rich content to a variety of types of "receivers". These receivers are typically some form of television, computer monitor, or flat screen display with a  media  player attached. They emulate the appearance of signs, billboards, and kiosks, located in prime locations for exposure to your desired demographics. These players can then be selectively updated with scheduled, rapidly produced, and rapidly adapted programming. National Electric Code (NEC)—Electrical safety code adopted by many jurisdictions around the United States, published by the National Fire Protection Association. Negative Space—The area around and within the art and copy. Also known as white space. See also  Positive Space. Neon—A rare inert gas which, when an electric current is discharged through it, produces a reddish-orange glow. The word neon is also often used synonymously to describe a type of luminous tube sign, which may contain other inert gases such as argon. Nesting—The ability of a RIP program to intelligently arrange multiple print jobs efficiently in order to minimize substrate waste when printing. Also the efficient placement of images or jobs in order to minimize waste when cutting. Network—Connection of computers with cables and software for constant, on-demand communication. With a network, several computers can use or control software installed on a central computer, or server, dedicated to one or a few functions. Network Manager—In electronic digital signage a device used to control flow of content to screens in various locations. & D I G I TA L G R A P H I C S 5/31/13 12:37 PM
