- ECF
- Elemental Chlorine Free Pulp bleached without the use of chlorine gas.
- Eco System
- The plants, animals and microbes that live in a defined geographical area and the physical environment in which they live. An eco-system has the means of producing both energy and the materials for life on an ongoing basis.
- Electronic dot generation (EDG)
- A method of producing halftones electronically on scanners and pre-press systems.
- Electronic printing
- Any technology that reproduces pages without the use of traditional ink, water or chemistry.
- Electrophotography
- Image transfer systems used in copiers to produce images using electrostatic forces.
- Elliptical dot
- In halftone photography, elongated dots which give improved gradation of tones particularly in middle tones and vignettes-also called chain dots.
- Em
- In composition a unit of measurement exactly as wide and high as the point size being set. So named because the letter ?M? in early fonts was usually cast on a square body.
- Embossed finish
- Paper with a raised or depressed surface resembling wood, cloth, leather or other pattern. The embossing can be partially "pulled out" during printing, this may cause misregister in multi colour printing on embossed stocks.
- Embossing
- Impressing an image in relief to achieve a raised surface; either overprinting or on blank paper (called blind embossing).
- Emulsion side
- In photography, the side of the film coated with the silver halide emulsion.
- En
- In composition, one-half the width of an em.
- Enamel
- A term applied to a coated paper or to a coating material on a paper.
- Environmental Management System
- Part of a general management system, consisting of organisation structures, planning functions, responsibilities, practices, procedures, processes and resources for developing, implementing, fulfilling, analysing and maintaining a company's environmental policy.
- EPSF (encapsulated postscript file)
- An alternative picture file format that allows postscript data to be stored and edited and is easy to transfer between Macintosh, MS-DOS and other systems.
- Etch
- In photoengraving, to produce an image on a plate by chemical or electrolytic action. In offset lithography, an acidified gum solution used to desensitise the non-printing areas of the plate; also, an acid solution added to the fountain water to help keep non-printing areas of the plate free from ink.
- Expanded type
- A type whose width is greater than normal.
- Exposure
- The step in photographic processes during which light produces the image on the light-sensitive coating.
