Printing Terms E - H
EPS (Encapsulated PostScript)
A standardized format that is used to store PostScript images.
A popular LAN (Local Area Network) used on many desktop publishing systems. It usesthree different connections, thin-net, thick-net, and twisted pair.
The period of time during which a light-sensitive surface is subjected to the action ofactinic light.
A cable that carries light instead of electricity. It is used to send massive amounts of information, far more data then possible over other transmission methods.
A device (usually another computer) that is part of a LAN, and is used to store and manage files.
Sheets of flexible translucent or transparent acetate, vinyl, or other plastic-based materials that are coated with a photographic emulsion.
A sheet of film or goldenrod paper to which negatives or positives have been attached (stripped) for exposure as a unit onto a printing plate.
A photographic defect in which the image is either locally or entirely veiled by a deposit of silver. Caused by stray light or improperly compounded chemical solutions.
A complete set of alphabet characters with a specific unique design that include upper and lower case, the numerical figures and punctuation marks.
The process of dividing a diskette or hard drive into the system required sectors and tracks.
Four-Color Processing Printing
The photomechanical reproduction of multicolor images achieved by overprinting specified amounts and areas of yellow, magenta, cyan, and black inks.
FTP (File Transfer Protocol)
The tool used to retrieve information in the form of electronic files from any number of computer systems linked via the TCP/IP protocol. Users in effect transfer copies of information found on remote computers either directly to their own computers or to a service provider's network and then to their own computers.
An image extending to all four edges of the press sheet, leaving no visible margins.
(1) The raw output of a phototypesetter, usually in the form of single columns of type on longs sheets of photographic paper, which serve as preliminary proofs. (2) the final typeset or imageset copy output to photographic paper, or directly to film.
The greatest possible range.
GCR (Gray Component Replacement)
A more sophisticated version of Under Color Removal that uses the most modern scanners and digitizing techniques available. This process replaces with black ink those areas where the three colors – Magenta, Cyan and Yellow – overlap in equal amounts. Because black ink is cheaper and easier to run on press, this technique has reduced the cost of color printing.
GIF (Graphic Interchange Format)
Originally developed specifically for compressing photographic images online, GIF is the most common method of encoding and storing picture files on the World Wide Web.
Means one billion bits.
Means one billion bytes of characters.
Allied industries, including printing, publishing, advertising, and design, that participate in the production and dissemination of text and images by printed or electronic means.
A computer video board that allows the monitor to display graphics and illustrations.
The values for yellow, magenta, and cyan that produce a neutral gray with no dominant hue when printed at normal density.
A reflection or transmission film strip showing neutral tones in a range of graduated steps. Exposed along with originals during photography, it is used to time development, determine color balance, or measure density range, tone reproduction, and print contrast.
The neutral clamps or fingers located on impression cylinders and transfer cylinders that grasp and hold a sheet while being transported through the press.
Tone values represented by a series of evenly spaced dots of varying size and shape, the dot areas varying in proportion to the intensity of the tones they represent.
A magnetic storage device.
The portion of the photograph that is lightest. In a halftone, these highlight areas have the tiniest dots or no dots at all in some areas.
HTML (Hypertext Markup Language)
The hypertext document format used on the World Wide Web.
HTTP (Hypertext Transfer Protocol)
The Internet standard supporting the exchange of information on the World Wide Web
