The Heidelberg website glossary explains, in alphabetical order, a multitude of terms relevant to printing, as well as some terms used in Heidelberg's product catalogue.

Simply click on the letter of your choice to access the information you need.

E-book
Refers to both the electronic version of a text that can be purchased as a CD or downloaded from the Internet and the electronic device that can be used to display such texts. The latter is, however, properly called an "e-book reader".
E-commerce
Describes business processes or transactions carried out over the Internet.
E-payment system
A system in which purchases and payments are processed electronically using the Internet. Such systems often employ trust centers and digital signatures in order to prevent theft and misuse of data and information. E-payment systems generally require a complex IT infrastructure.
E-procurement
The business-to-business purchase and sale of supplies and services over the Internet. Also referred to as web-enabled electronic purchasing. It automates the traditional manual and paper-based procurement process, thus resulting in reduced maverick buying, lower transaction costs, lower cycle times, and increased efficiency.
EAN code (European Article Numbering code)
Code defined to assist in the universal identification of all types of goods by means of an internationally-standardized article number. Two different versions of this code exist, one containing 13 figures and the other eight (EAN-13 and EAN-8). An EAN code generally includes the country of origin, the manufacturer and the product’s article number.
EB ink (electron beam color)
A printing ink that is dried with the use of electron beams. Similar to UV inks, which are cured by ultraviolet light, EB inks are cured by means of polymerization, which is made possible by the direct effect of the electrons on polymerizable substances. Unlike UV inks, special initiators are not required for EB inks and as a result EB inks are easier to store. The special advantage of EB inks is, however, the thickness of the layers that can be applied, as the electron beams penetrate deeply.
Editor
A software program used to write and edit HTML code.
Effect coating
Coatings used to lend a printed product a unique appearance or quality; usually refers to pigmented coatings, which vary greatly according to the pigments in the ink and the size and shape of the particles.
Electronic paper
In an attempt to combine the electronic activation of a monitor with the superior legibility of printed paper, Massachusetts Institute of Technology (MIT) and various manufacturers are working on what is known as electronic paper. In one version, the paper contains tiny spheres with different colors on different sides, which rotate when exposed to electric fields and thus present different colors. Another type of electronic paper contains small, transparent capsules filled with dye and white particles. When an electrical field is applied, these particles float to the top, making the surface of the paper look white. Otherwise, the effect of the dye is dominant. Back to top


Electronic signature

Em dash
The longest form of the dash, the length of which is equivalent to the width of the letter “M”; used in English to denote a break in sentence structure.
En dash
Shorter than the em dash (its length is equivalent to the width of the letter “N”), it is used to replace the word “through” when listing inclusive numerals or dates.
Enlargement scale
See "reproduction scale".
EPS (encapsulated postscript)
A standard file format used to transfer a graphic from one application or platform to another. Pure EPS can not be displayed on the monitor and therefore a preview must be created in TIFF or another format. EPS graphics can be enlarged without loss of quality.
ERA (European Rotogravure Association)
Headquartered in Munich, the association was founded in 1956 by European gravure print shops; manufacturers from the industry are associate members.
Esthetic program
Feature of a layout program that ensures that the text flows with visual appeal, in accordance with typographic rules. The features of such a program include the individual adjustment of the spaces between certain letter combinations (known as "kerning"), and corrections to the positions of line starts (for example a line beginning with "A" must be moved slightly outwards).
Esparto paper
A soft, bulky printing paper made from esparto grass, the stock of which is extremely opaque and, due to its low moisture pickup, features relatively high dimensional stability.
EUPRIMA (European Print Management System Association)
An association for suppliers of management information systems established in 2000, the primary task of which is to promote the electronic exchange of data between manufacturers, customers and suppliers in the print industry using the Job Definition Format (JDF). EUPRIMA works closely with CIP4 in advancing development work.
Euro scale
A color scale for the CMYK four-color model standardized in Europe in DIN 16 539 for offset printing and DIN 16 538 for letterpress printing. This defines the printing colors yellow, magenta, cyan and black according to hue, saturation and print sequence and enables them to controlled under standard conditions.
External drum exposure
Refers to a writing head that is placed outside the drum. The film or printing plate is clamped onto the outside of the drum and fixed via a vacuum. When the drum rotates, the writing head traverses the material to be imaged line for line. Back to top
