A method and a diagnostic device for a printing press are described, wherein data is automatically transmitted by a central data processor of the printing press to a locally distanced central data processor when a threshold value is upwardly transgressed, downwardly transgressed or reached. The data is preferably assessed prior to the evaluation and/or the transmission to the remote central data processor. In this way, a simple telediagnostic service of the printing press is possible.

A method for exposing a printing form includes providing a plurality of exposure channels disposed in a two-dimensional array, and inputting energy, by the exposure channels of a column of the array, for an image element on the printing form. Further included are steps for activating a first row of the array of exposure channels for producing a first component of the input of energy assigned to each column of the array in one row of image elements, moving the printing form relative to the exposure channels, and activating a second row of the array of exposure channels for producing a second component of the input of energy assigned to each column of the array when a point of projection of the exposure channel of a second row of the array comes to lie on the image element of the row already exposed by the exposure channel of the first row and the same column. A device for implementing the method and a printing unit and a printing press including the device are also provided.

A method for structuring a surface includes, by an assigned modification device, creating a latent structure of at least a first layer of the surface, which has a polymer therein, so as to form hydrophilic and hydrophobic regions for producing a printing form for offset printing, by selectively applying a gaseous, readily volatile solvent as a modifying agent to at least one locally limited region of the surface over at least one exposure time interval. A device for performing the method, a printing form exposer, a printing unit and a printing machine including the surface-structuring device according to the invention, are also provided.

A printing unit configuration includes an accessory and a connection mechanism moveably fastening the accessory thereto, throwing the accessory thereon into a working position, and removing it therefrom into maintenance positions. A linear guide can be connected to the accessory and disposed perpendicular to a pivot axis, with the mechanism pivoting the accessory away from the unit about the axis and displacing it along the guide. The mechanism can have two pivot axes disposed parallel to the unit rotation axis and can pivot the accessory away from the unit first about the first axis then about the second. The mechanism can pivot the accessory about an axis perpendicular to the unit rotation axis and/or about a single pivot axis disposed below the accessory. The mechanism can connect the accessory to the unit to project into a recess of a side wall of the printing machine at a side opposite an operator side in a maintenance position.

An apparatus for adjusting the position of a cylindrical image carrier relative to a scanning head is designed to cheaply and easily permit substantially reliable positioning. In the apparatus for adjusting the position of a cylindrical image carrier relative to a scanning head, in which apparatus the image carrier is mounted so as to be rotatable around its longitudinal axis, the image carrier can be swiveled around an axis perpendicular to the longitudinal axis. The invention can be applied to devices that generate images and to devices that reproduce images, in particular for the production of type forms and for the scanning of originals.
