Abstract

An apparatus and method for treating a rotating printing technology surface, especially a re-imageable printing form, with a process liquid, such as cleaning, covering or rinsing liquid, include jet nozzles disposed along a straight line substantially parallel to the axis of rotation of the printing technology surface, and a cloth device substantially parallel to the axis of rotation. The nozzles pivot about a pivot axis substantially perpendicular to the axis of rotation for producing a substantially uniform distribution of process liquid parallel to the axis of rotation. The cloth device preferably has a cloth with segmented or calendered portions substantially parallel to the axis of rotation, for substantially limiting spread of process liquid in the cloth parallel to the feed direction of the cloth and assisting substantially uniform distribution of process liquid parallel to the axis of rotation. Machines for processing printing material and for treating printing forms are also provided.
