DAR Digital Artwork and Reprographics. DCS Desktop Colour Separation, a procedure developed by Quark for the separation of text, graphics, etc. into the classic four-colour process printing. Dagger(s) Symbols used mainly as reference marks for footnotes. Dash A short horizontal rule used for punctuation. Default Thickness of paper. A setting or pre-set value a computer system starts with-until you change it. Density The opacity of the ink or image. Descender That part of a letter which extends below the main body, as in “p”. Deselect To “un-select” a folder, document, image, or text by clicking once somewhere off the item or page. Desk Accessories Small applications for special functions that are always available under the apple menu no matter what other program you may be using at the time. Desktop The working environment of the PC/Macintosh computer. Detail Enhancement The technique of exaggerating picture image edges with unsharp masking or peaking. The observer can easily see the detail of the original in the final reproduction. Dialog Box A box with a square-cornered border asking you to make a choice. Dialog boxes can have regular buttons, pop-up buttons and ballot boxes inside them. Die A hardened steel engraving stamp used to print an inked image. Used in the production of good quality letter headings. Die Cutting/creasing form A hardened steel ribbon of metal set into a wooden base used for creasing and cutting to shape printed matter. Digital Soft Proof Colour video monitor display of picture file, data file or text file. Dimmed The grey-out appearance of a menu, command or option not available to you at the time. Dingbat or Wingding Term used to describe an ornamental symbol indicating the end of an article. Direct Digital Colour Proof (DDCP) Proof made directly from stored data file onto a substrate , using a peripheral device such as a photographic exposure, dot matrix printer or ink jet printer without producing intermediate films. Direct Screen Method of colour separating which adds dots at the same time the transparency is being photographically separated into the four colours. Directory The list of the contents of a folder or a disk. You can look at this list in several ways; e.g. as an alphabetised list, by date with the last item you worked on first on the list, etc. Disk Circular shaped generally plastic material with a coating of material that can be magnetised on its surface. On this surface, which is similar to the same type of material in an audio or video tape, information can be recorded-or “saved”-as patterns of magnetism. Display type Larger type used for headings etc. Normally about 18 point or larger. Document The entity you create when you “save” when working within an application program. Domain Name The unique name that identifies an Internet site. Domain Names always have two or more parts, separated by dots. The part on the left is the most specific, and the part on the right is the most general. A given machine may have more than one Domain Name but a given Domain Name points to only one machine. Usually, all of the machines on a given network will have the same thing as the right-hand portion of their Domain Names; e.g., gateway.gbnetwork.com, mail.gbnetwork.com, www.gbnetwork.command, so on. It is also possible for a Domain Name to exist but not be connected to an actual machine. This is often done so that a group or business can have an Internet e-mail address without having to establish a real Internet site. In these cases, some real Internet machine must handle the mail on behalf of the listed Domain Name. See: IP Number Dot Area Size of the dot is indicated by the percentage of the area it occupies from zero to one hundred percent. Dot Etching Applying chemicals by hand to negatives for increasing dot size which adds colour, or to positives for decreasing dot size which subtracts colour. Dot Gain The increase in the printing dot size from the halftone film to the printed substrate, resulting in darker tones. Double-Black Duotones This process requires two films and two plates. Both plates are inked with black for the most contrast. Double Burn Utilising two (or more) negatives to expose an image on a plate or positive print. Double-click The shorthand way to open a folder, application or document. You double-click by placing the cursor over the icon (of the document, application, etc.) and quickly press the mouse button twice-without moving the mouse. Double page spread Two facing pages of newspaper or magazine where the textual material on the left hand side continues across to the right hand side. Abbreviated to DPS. Downloadable fonts Type faces which can be stored on a disk and then downloaded to the printer when required for printing. These are, by definition, bit-mapped fonts and, therefore, fixed in size and style. DPI (Dots Per Inch) the measurement of resolution for page printers, phototypesetting machines and graphics screens. Currently graphics screens reproduce 60 to 100dpi, most page printers work at 300dpi and typesetting systems operate at 1,000dpi and above. Drag or Grab The way you move icons and other objects in Macintosh windows. Place the cursor over the icon, press and hold down the mouse button, and move the mouse. When the object is at your intended location, you release the mouse button. Drawn on A method of binding a paper cover to a book by drawing the cover on and gluing to the back of the book. Drilling Holes for two, three or four ring binding are drilled, rather than punched. The standard hole punch used in most offices can only punch a few sheets at a time. However, a specialised drilling machine performs the same function on up to 1000 sheets in a single pass. Driver A software program that directs the operation of a device outside the computer. To operate a scanner or a printer, the controlling software program must reside in the machine. Dry transfer (lettering) Characters, drawings, etc, that can be transferred to the artwork by rubbing them off the back of the transfer sheet. Best known is Letraset. Drop-Out Technique that can give a mediocre photo greater contrast by photographically removing some dots to create highlights, showing the actual white of the paper. Drop-in Colour Changing the colour of the original line drawing or text (usually black) to a new colour is sometimes referred to as a Drop-in Colour. Most often used to create text and background colours. Dummy A preliminary layout showing the position of illustrations and text as they are to appear in the final reproduction. A set of blank pages made up in advance to show size, shape, form and general style of a piece of printing. Duotone Two films made by changing the screen angle for each. One plate is made for each film. A duotone is printed in two colours but both plates can be used for the same colour ink for maximum contrast. When using black ink this is called a “double black". DVD (Digital Versatile Disk or Digital Video Disc). This medium is similar to CD except that it holds up to seven times more data.
