Embodiment Construction

[0032] Printing plate 01 (e.g. printing plate 01, in particular lithographic printing plate 01) is designed as printing plate 01 of a printing press, e.g. machine) plate cylinder plate 01. Preferably the printing press is designed as a printing press for waterless offset printing. A corresponding offset printing unit has at least one plate cylinder (in particular a plate cylinder), a transfer cylinder (in particular a blanket cylinder) associated with the plate cylinder, and an impression cylinder associated with the transfer cylinder. At least one printing forme 01 is arranged on the forme cylinder. A plurality of printing formes 01 are preferably arranged successively on the printing plate cylinder in the direction of the rotational axis of the printing plate cylinder. Regardless of whether several printing formes 01 are arranged successively in the direction of the axis of rotation of the printing forme cylinder, several printing formes 01 can also be arranged one after t...

Abstract

The invention relates to a printing plate and a method for producing a printing plate. First, a first of two opposite main surfaces of a metal web or a metal sheet is defined as a working surface, and a second of the two main surfaces is defined as a bearing surface. A coating is applied onto the working surface, and at least one printing plate is then separated from the metal web or from the metal sheet. During said separation process and / or during at least one additional separation process, at least one printing plate lateral surface that adjoins both the first and the second of the two main surfaces is produced, said lateral surface having at least one ridge that projects past the first main surface in a first direction of a surface normal of the first main surface. After the at least one separation process, the at least one ridge is shaped in at least one shaping step such that said ridge projects less far than before the at least one shaping step and / or no farther past the first main surface.

Description

technical field [0001] The invention relates to a method of producing at least one printing form according to the features of claim 1 and to a printing form according to the preamble of claim 13 . Background technique [0002] The printing formes, in particular the printing forme cylinders of a rotary offset printing press, each carry at least one printing image with a print and are usually arranged exchangeably on the corresponding printing cylinder. Printing plates are often used as printing plates. It preferably consists of a dimensionally stable but flexible support plate made of metal, such as aluminum, and usually at least partially has a coating that is hydrophilic and / or ink-impermeable. In the manufacture of such printing plates, metal sheets or strips are usually used, from which the printing plates are separated in suitable dimensions. After the first separation of the printing plate and, for example, after mapping, other separations can be used, such as to corr...
