A method for the indirect application of printing liquid onto a printing material provides an intermediate carrier, preferably a circulating belt, a liquid conditioning medium including a first substance applied onto the intermediate carrier and a printing liquid, in particular an inkjet ink, including a second substance applied onto the conditioning medium on the intermediate carrier. The printing liquid is situated as droplets or a layer substantially on the conditioning medium and the droplets or the layer form a contact region on their underside with the conditioning medium. The printing liquid is heated, preferably by way of a dryer and the printing liquid is transferred from the intermediate carrier onto the printing material.

A printing unit for a printing press includes a plurality of distributor rollers for carrying out an axial movement. At least one of the distributor rollers is associated with a separate drive motor exclusively for driving the axial movement and is adjustable independently of the movements of the other distributor rollers by using a control device.

A system for coating a printing material with a fluid includes a printing press. The printing press includes a metering apparatus for metering the fluid, which is disposed within the printing press, an intermediate storage container for the intermediate storage of the fluid, which is disposed within the printing press, and a first delivery pump for delivering the fluid from the intermediate storage container to the metering apparatus, which first delivery pump is disposed within the printing press. The metering apparatus, the intermediate storage container and the first delivery pump together form a circuit. A supply storage container stores the fluid and a second delivery pump delivers the fluid from the supply storage container to the intermediate storage container.

A cylinder for processing sheets of printing material includes a clamping channel having a central region and edge regions. A tool plate punches and/or scores and/or perforates the sheets. A support plate carries the tool plate. A first clamping system clamps the support plate and has a first holding device for holding a front end of the support plate and a second holding device for holding a rear end of the support plate. The first holding device and the second holding device are disposed in the edge regions. A second clamping system clamps the tool plate and has a third holding device for holding a front end of the tool plate and a fourth holding device for holding a rear end of the tool plate. The third holding device and the fourth holding device are disposed in the central region. A printing press having the cylinder, is also provided.

A printing press includes a cylinder, rollers each being selectively displaceable into an active position on the cylinder, a roller magazine for the rollers, and a protective cover for the roller magazine. The protective cover is mounted so as to be adjustable movably between the roller magazine and a respective one of the rollers that has been displaced into the active position.
