An ink dosing device for inking units of printing presses has several dosing elements that are adjustable independently of one another. The dosing elements are provided for over the length of an ink fountain, whereby each dosing element shows a dosing area that is adjustable in its clearance to the ink fountain roller, and in each zone the smallest amounts of ink can be adjusted.

Ink dosing device for inking units of printing presses

A method of washing an offset printing press having a plate cylinder, a rubber blanket cylinder, an impression cylinder, an inking unit a paper thickness compensator and a damping unit. The inking unit and the damping unit include, respectively, inking rollers and damping solution applicator rollers. The offset printing press also includes a washing apparatus. The washing apparatus, when in the wash mode, is placed in engagement with the rubber blanket cylinder of the printing press by control apparatus. Also, in the wash mode, the impression cylinder is engaged with or disengaged from the rubber blanket cylinder by a paper thickness compensator. The usual purpose of the paper thickness compensator is to compensate for the thickness of the stock in running-on mode but is employed herein also to effectuate washing of various rollers and/or cylinders of the printing press.

Method of washing a printing press with a washing apparatus

The invention relates to a rotary printing press, particularly offset printing press, the printing unit of which comprises a printing form, a damping unit as well as an inking unit, said inking unit being provided with a set ink profile. In order to obtain a fast change of ink profile, it is proposed that, in order to eliminate the previous ink profile and to prepare the buildup of a new ink profile, the printing form 32 is inked over its entire surface area with the inking unit 1.

Preparation of the inking unit of a printing press for a change of

A printing press having an inking unit and a wetting unit, which cooperate with a printing form by means of an inking roller and a wetting roller, having a control device for moving the wetting roller into an engagement or disengagement position with respect to the printing form. To expedite simple handling in the application of another substance onto the printing form, the wetting roller is supplied with the another substance by an apparatus provided therefore and moved into its engagement position with respect to the printing form by a control apparatus.

Sheet fed rotary printing press

A process for setting a production run ink zone profile on an offset printing press. Initially, an ink zone profile is established which is the reverse of the desired ink zone profile, and, thereafter, this reverse ink profile is switched over to the ink profile actually desired.
