electronic printing – In digital printing, any technology that reproduces pages without the use of traditional ink, water or chemistry.
electrostatic copying – Process using an intermediary plate or drum (like Xerography) or coated take-off sheet (like Electrofax™) which is electrically charged to attract powder or liquid developer only to the image area.
elemental chlorine-free (ECF) – Indicates virgin or recycled fiber that is bleached with chlorine dioxide or other chlorine compounds. This process significantly reduces hazardous dioxins, but does not completely eliminate them.

embossing – Impressing an image in relief to achieve a raised surface; either over printing or on a blank paper (called blind embossing).
emulsion – The film and print paper coating that is light-sensitive (photo-sensitive). Because coating is fragile, emulsion should be treated carefully. Film should be shipped with the emulsion side carefully protected from scratching.
emulsion up and emulsion down – When asking for film to be output, you must request the emulsion as up or down. Emulsion down is most common. Though a few magazines require film that is imaged emulsion up.
en – In composition, one-half the width of an em.
encapsulated PostScript (EPS) – In digital prepress, a file format used to transfer graphic images within compatible applications. A file containing structured PostScript code, comments and a screen display image.
end-leaf paper – Strong, fine quality papers, either plain or coated and sometimes colored or marbled used at both ends of a book. Also called sheets.
engraving – Printing by the intaglio process. Ink is applied to the paper under extreme pressure resulting in a printed surface being raised. Used for fine letterheads, wedding invitations, etc.
