The following definitions will appear on the DTP quiz. The quiz will take place in class on Monday, October 31.                  
ASCII
(American Standard Code for Information Interchange) A Standard editable format for encoding data.
Bezier curve
A curved line segment< consisting of anchor points with direction lines with which the curve can be reshaped. Bezier curves can be created in illustration software such as SuperPaint, FreeHand and Illustrator.
Bit
(Binary Digit) The smallest unit of information on a computer. Eight bits equal one byte.
Bit depth
The number of bits used to store a pixel¹s color or grayscale information on a computer screen.
Bitmap:
The display of a picture on  computer screen via the geometric mapping of a single layer of pixels on a rectangular grid.
Byte
The basic unit of storage memory. One byte is equal to eight bits.
Clipboard
An area of memory used to  temporarily store a selection. The Clipboard is accessed via the Cut, Copy, and Paste commands
CMYK  
(Cyan, Magenta, Yellow, and Black) The four colors of ink used in process printing. Cyan, Magenta, and Yellow are the three subtractive primaries. When combined in their purest forms, they theoretically produce black. Actually, they produce a dark muddy color. CMYK colors are simulated on a computer screen, using additive colors. To color separate a picture from PhotoShop, it must be in CMYK Color mode
Color separation
The production of a separate sheet of film for each color of ink that will be used to print a document. Four plates are used in process color separation, one each for Cyan, Magenta, Yellow and black.
Continuous-tone Image
A picture, such as a photograph, in which there are smooth transitions between gray shades or colors.
Contrast
The degree of difference between lights and darks in a picture. A high contrast picture is comprised of only the lightest and darkest pixels.
Crop Marks  
Short, fine lines placed around the edges of a page to designate where the paper is to be trimmed by a print shop.
Digitize
To translate flat art or a transparency into computer-readable numbers using a scanning device and scanning software.
Dot gain
The undesirable spreading and enlarging of ink dots on paper.
DPI
(Dots Per Inch) A unit used to measure the resolution of a printer. DPI is sometimes used to describe the input resolution of a scanner, but ppi or ³sampling rate² is a more accurate term.
EPS
(Encapsulated Postscript) A picture file format containing PostScript  code and, in the case of Photoshop, an optional PICT image for screen display. EPS is a commonly used format for moving files from one application to another and for imagesetting and color separating.
Film negative 
A film rendition of a picture in which dark and light areas are reversed.
Gigabyte
(G) or (Gb) A unit of memory equal to 1,024 megabytes. (see Megabyte)
Grayscale
A picture containing black, white, and up to 256 shades of gray, but no color. In Photoshop, Grayscale is a one-channel mode.
Halftone screen
A pattern of tiny spots used for printing a picture to simulate smooth tones. (see Screen frequency).
Highlights
The lightest areas of a picture.
Imagesetter
A high-resolution printer (usually 1,270 or 2,540 dpi) used to generate paper or film output from computer files.
Kern
To adjust the horizontal spacing between a pair of characters.
Leading
The space between lines of type, measured from baseline to baseline. 
LPI
(Lines Per Inch),The unit used to measure the frequency of rows of spots on a halftone screen.
Marquee
The moving border that defines a selection.
Megabyte
(M, MB) A unit of memory equal to 1,024 kilobytes. (see Kilobyte)
Midtones
The shades in a picture midway between the highlights and shadows.
Object-oriented
A software method used for describing and processing computer files. Object-oriented graphics and PostScript type are defined by mathematics and geometry. Bitmapped graphics are defined by pixels on a rectangular grid. Photoshop  and Paint pictures are bitmapped, not objected-oriented.
Pica
A unit of measure used in typography equal to 1/6 inch or 12 points.
PICT
Quickdraw picture. The original file-swapping format developed by Apple for transfering bitmapped and object-oriented pictures from one graphic application to another. The College scanner software saves in PICT.  PCIT can be imported into RSG.
PPI
(Pixels per inch) A unit used to measure of the resolution of a scan or a picture.
Point
A unit of measure used to describe type size (measured from ascender to descender), leading (measured from baseline to baseline), and line width. Equal to 1/72 inch.
PostScript
The page description language created and licensed by Adobe Systems Incorporated for displaying and printing fonts and pictures.
Process color
Ink printed from four separate plates, one  each  for Cyan (C), Magenta (M), Yellow (Y), and Black (K), which in combination produce a wide range of colors.
RAM
(Random Access Memory) The system memory of a computer used for running an application, processing information, and temporary storage.
Registration marks
Crosshair marks placed around the edge of a page that are used to align printing plates.
Resolution
The fineness of detail of a digitized image (measured in pixels per inch),  a monitor (measured in pixels per inch-usually 72 ppi), a printer (measured in dots per inch), or halftone screen (measured in lines per inch).
Scan
To digitize a slide, photograph or other artwork using a scanner and scanning software so it can be displayed, edited, and output from a computer.
Screen frequency
(also known as screen ruling) The resolution (density of spots) on a halftone screen, measured in lines per inch. (see lpi)
Shadows
The darkest areas of a picture
Spot color
A mixed ink color used in printing. A separate plate is used to print each spot color. Pantone is a commonly used spot color matching system. (see Process color)
TIFF
(Tagged Image File Format) A file format used for saving bitmapped images, such as scans. TIFF pictures can be color separated.
