A technique for the imaging of offset plates, by which a thermal erosion layer is removed. The printing plates then only require mechanical treatment and in some cases can be rinsed with water. The main disadvantage of this system is that it produces debris which must be removed from the CTP system.

See zig-zag fold.

A software program developed by Adobe, which allows documents to be viewed using a reader (available free of charge) on every commonly used computer platform and to be printed on PostScript printers. The major advantage of the program is that all fonts, colors and the layout itself are identical to the original document, even if the fonts or the program used to create it are not installed on the viewer's computer. It is a global standard in document management.

A shortened form of a word or compound term usually formed from its initial letters.

A color produced through the addition of light of various colors. In theory, every color can be produced by mixing the primary colors of the visible light spectrum: red, green and blue (RGB), as the color vision of the human eye works through red-, green- and blue- sensitive sensory cells. RGB is the usual additive color system and is used predominantly for television screens, computer monitors and scanners. Combining two of the primary colors in equal parts produces the secondary colors cyan, magenta and yellow, which in turn form the basic colors of the subtractive color system (CMYK).

This is the process of producing color through the addition of different colors of light. Computer and television screens use thousands of red, green, and blue phosphor dots, which are so small and close together that the human eye cannot see them individually. Instead, the eye sees the colors formed by the mixture of light.

A binding method which uses thread-free adhesives to secure loose leaves into a solid text block.

Administrator Person with all rights of access to a network and responsible for its management and maintenance.

To place the material to be cut at the correct position in the machine.

An eight-bit storage segment reserved for masks in an image processing software program; a feature incorporated into image processing software programs and image data formats for storing processing routines and an image's special properties (for example, background transparency).

Folding a sheet of paper so that two flaps are formed that can be opened from either side.

A halftone screening method in which equidistant dots are used, the variation of the size of which produces continuous tone pictures. In combined printing, several color forms must be arranged at varying, exactly defined screen angles in order to avoid moiré patterns.

Defines the start or end of a path segment (a path consists of one or more segments). They fix the path at a specific position. The path segments and the shape of the path are changed by moving the anchor points.

An old term for flexographic printing whose name is derived from the aniline-based inks employed during the process. Printing presses using this process employ rubber rollers as letterpress forms and print with quick-drying, low-viscosity inks. The first presses of this type appeared on the market at the beginning of the 20th century. They were mainly used to print packaging material.
