| Imagesetter An ultra-high resolution large-format computer output device which exposes rolls or sheets of either photographic film or bromide paper to a laser light source. Once the film or paper is developed, a very high quality black-and-white image is revealed. Development usually occurs in a unit separate to the imagesetter |
Imposition One of the fundamental steps in the prepress printing process. It consists of the arrangement of the printed product’s pages on the printer’s sheet, in order to obtain faster printing, simplify binding and reduce paper waste.
Correct imposition minimizes printing time by maximizing the number of pages per impression, reducing cost of press time and materials. To achieve this, the printed sheet must be filled as fully as possible. |
| Impression Cylinder The part of an offset lithographic printing press which carries the paper or other substrate through the printing unit and beneath the inked press blanket. The impression cylinder also provides a hard backing which allows the blanket to press a strong and solid impression on the paper. |
| Ink Balance Maintaining the ratio of cyan, magenta and yellow ink to produce a picture with the desired color and without an unwanted color cast or color bias. |
| Ink Holdout The ability of paper to prevent ink from penetrating into its surface (in contrast to ink absorbency). |
Ink Jet Printing The type of computer printing that recreates a digital image by propelling droplets of ink onto paper, plastic, or other substrates. Inkjet printers are the most commonly used type of printer, and range from small inexpensive consumer models to expensive professional machines.
The technology was first extensively developed in the early 1950s. Starting in the late 1970s inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, HP, and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Epson, and Brother. |
| Insert In print advertising, an insert or blow-in card is a separate advertisement put in a magazine, newspaper, or other publication. They are usually the main source of income for non-subscription local newspapers and other publications. |
Intaglio Printing The family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. It is the direct opposite of a relief print.
Copper or zinc plates are usually used as a surface or matrix, and the incisions are created by etching, engraving, drypoint, aquatint or mezzotint. Collagraphs may also be printed as intaglio plates. Intaglio printmaking emerged in Europe, the earliest known surviving examples originating from 15th Century. The technique was extensively used in art production. Albrecht Dürer, William Blake, Francisco Goya, Rembrandt and Max Klinger are, among other things, renowned for their intaglio artwork. |
| Integral Proof A proof made by exposing each of the four-color separations to an emulsion layer of primary colors. These emulsion sheets are stacked in register with a white sheet of paper in the background. Types of integral proofs are cromalin, matchprint, ektaflex, and spactraproof. |
| Interleaves Slip sheets between prints as they come off press. |
ISBN The International Standard Book Number (ISBN) is a unique numeric commercial book identifier.
An ISBN is assigned to each edition and variation (except reprintings) of a book. For example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, and 10 digits long if assigned before 2007. The method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. |
