Adobe PostScript

A page description language developed by Adobe Systems Incorporated.

The standard Postscript type 1 fonts Times, Helvetica, Courier Symbol and Zapf Dingbats with associated italicised and bolded styles.

The representation of black using only the K component, instead of a combination of C, M, and Y.

Extending the image beyond the finished trim size so that the image runs right to the edge of the printed sheet after trimming and binding.

Graphic images consisting of many tiny cells of numerical computer data. The number of cells determines the resolution of the bitmap, while the value of each cell establishes the density or darkness of each cell and therefore its tone.

An acronym for the four process colours: cyan, magenta, yellow, and black.

An acronym for Desktop Colour Separation, a data file standard defined by QuarkXPress™ to assist in making colour separations with a desktop publishing system. Using DCS, five files are created: four colour files containing cyan, magenta, yellow, and black image data, and a composite colour view file of the colour image.

Dots per inch.

Software that aids in the transfer of information between the computer and the peripheral controlled by the driver software program. In publishing, the most common drivers are printer drivers. Such as the Adobe postscript printer driver included with Adobe Acrobat 4.05 (Adobe .ps)

A halftone image created by over- printing two different halftone screens of the same image with different tonal values. Duotones are printed using two black inks or a black and a coloured ink. Duotones are created to increase the detail and saturation of the black part of an image, or to create a special effect.

An acronym for Encapsulated PostScript, a file type that is created by a wide variety of computer programs. EPS files contain all of the vector and bitmap information necessary to image a single page. These files are usually not intended to be printed by themselves, but are placed in a page design and then printed.

Data represented by only the K component.

Adobe’s new page layout program. Enables you to create PDF files from directly within the application. See http://www.adobe.com/products/indesign/main.html

An acronym for Joint Photographic Experts Group, an ISO group that has established a standard for the compression of bitmapped, scanned, and rendered colour images.

A single colour. Monochrome usually refers to a black- and- white image.

An acronym for Open Prepress Interface, a communication connection developed by Aldus Corporation that facilitates links between CEPS and desktop publishing systems. Using OPI, view files or high resolution scans can be transferred to desktop publishing systems and placed in page layout software. When the page file is sent back to the CEPS for processing and output, the high resolution image data is automatically swapped for the view file. OPI is frequently used by systems that seek to maintain high- resolution image data separate from page layout files. OPI is often compared to DCS.

An acronym for Portable Document Format. Created by Adobe Systems, PDF is a file format used to represent a document in a manner independent of the application software, hardware, and operating system used to create it.

An acronym for PostScript Printer Description file. Each PostScript printer has an associated PPD file, which contains information used by printer drivers and some applications to control the PostScript creation criteria. Such as the (Acrobat PPD).

A printer description file used by QuarkXPress™ 3.3.1 and earlier versions of the software to read PPD files. Quark PDF files are not used in QuarkXPress™ 3.3.2 or later.

A third party Ad Delivery System for supplying advertising material to some magazine and newspaper publishers. See http://www.quickcut.com.au

An acronym for red, green, and blue, the three primary colours blended to create the spectrum of colours displayed on a colour monitor.

An acronym for Tagged Image File Format, a standard format developed by Aldus Corporation for bitmap or raster graphics – usually scanned images. TIFF can handle a variety of image data, from 8- bit black- and- white images to 24- bit colour RGB or CMYK images.

The intentional overlapping of colours along common boundaries to prevent unprinted paper from showing in the event of misregistration in printing.

An acronym for undercolour removal. UCR is the technique for reducing the cyan, magenta, and yellow content in neutral gray shadow areas of a reproduction and replacing them with black ink so that the reproduction will appear normal but will use less process colour ink.

A compression method that does not remove data to achieve compression.
