A service tracking system for a printing press (1), spray applicator (1′) or the like includes at least one replaceable component (10) having at least one memory unit (20). The service tracking system further includes a controller (30) which is connected to the memory unit (20). The controller (30) is configured to control the operation of the replaceable component (10) and to periodically update data stored on the memory unit (20) related to run-time data regarding the operation of the specific replaceable component (10).

The cleaning device (20) for cleaning a cylindrical roller (50), for example an anilox roller of a printing machine, includes a cleaning head (30) with a cleaning chamber (110), in which there is housed a mechanical cleaning member (60), and with which there are associated feeding members (70) for feeding a cleaning liquid into the cleaning chamber (110). The mechanical member (60) and cleaning liquid dispensed by the feeding members work in combination inside said cleaning chamber (110) to clean the lateral surface of the roller (50)

A cleaning device for a surface of a cylinder of a printer and/or a copier includes a cylindrical cleaning element which can be rotated by at least one drive and which includes a cleaning fitting on its outer periphery, and a suction or suctioner conducting at least one suction medium with at least one suction channel aligned towards the outer periphery of the cleaning element and extending along the longitudinal alignment of the cleaning element. In order to achieve a simple technical structure and a low maintenance effort apart from a good cleaning result and reliable dirt removal, a suction slit extending longitudinally of the suction channel is aligned towards the cleaning element opens into the suction channel tangentially to the suction channel cross section.

In an example, a method includes rotating a print apparatus component to be cleaned about a first rotational axis. A cleaning element having a cleaning surface in contact with the print apparatus component may be driven such that the cleaning surface has a component of motion which is parallel to the first rotational axis in a contact region. A relative velocity of the cleaning element and the print apparatus component may be varied during a cleaning operation.

The present invention aims to provide a method of producing a printed matter that shows suppressed scumming in planography. A method of producing a printed matter, the method including the steps of: allowing a dampening water to adhere to a hydrophilic layer of a planographic printing plate having at least the hydrophilic layer and a heat sensitive layer; allowing an ink to adhere to the heat sensitive layer; and transferring the ink adhering to the heat sensitive layer to an object to be printed; wherein the pH (A) of the ink and the pH (B) of the dampening water are both from 1 to 6.5.
