A method operates a flexographic printing press. The press contains a printing cylinder carrying a sleeve with at least one flexographic printing forme or a flexographic printing cylinder and an impression cylinder forming a printing nip with the printing cylinder to print on a web of printing substrate. The method includes automatically adjusting the transport speed of the web of printing substrate as a function of a dot density of the flexographic printing forme, i.e. of a location-dependent density of printing elevations on the flexographic printing forme, or of data computationally derived therefrom, or as a function of gaps of the flexographic printing forme or printing cylinder or data computationally derived therefrom. The printing press advantageously provides a cost-efficient way of producing high-quality prints in an industrial flexographic printing process while avoiding undesired vibration. In addition, the method of the invention advantageously provides further automation of the printing process.

The present invention pertains to a device for producing printed products comprising an arrangement of cooperating rollers that are arranged parallel to one another, wherein at least the gap width between the rollers of one roller pair is adjustable. For this purpose, one roller of the pair is pivotably mounted by means of a pivot arm, wherein a driver arranged on the pivot arm displaces a linearly movable reference element by means of a sliding block guide such that the position of this reference element corresponds to the adjusted gap width. The sliding block guide is preferably realized in such a way that the gap width and the position of the reference element are proportionally correlated.

A web transport system for transporting a web of media along a web transport path in an in-track direction, including a liquid application system for applying a liquid to at least one surface of the web of media. An air skive is positioned along the web transport path downstream of the liquid application system, wherein the air skive directs one or more streams of air onto the web of media thereby removing at least some of the liquid that is being carried along with the web of media. A vapor source adds a vapor into the one or more streams of air provided by the air skive before the one or more streams of air are directed onto the web of media.

In some examples, a sheet processing machine includes at least one infeed system including at least one transport means including at least one upper holder and at least one lower holder. The at least one transport means can be and/or is arranged in at least three states: a maximally closed state corresponding to a minimal distance, a minimally closed state corresponding to a maximal distance, and an at least one mean state corresponding to at least one mean distance between at least one upper holding surface at least of the respective upper holder, and at least one lower holding surface of the lower holder of the at least one transport means that is assigned to the respective upper holder. During a machine cycle, the at least one transport means has each of the minimally closed state, the maximally closed state, and the at least one mean state at least once.

A printing press is provided which includes a printing unit for printing on a web. The printing unit includes a plate cylinder, a blanket cylinder, and an impression cylinder. The press further includes a web displacement bar movable between a first position in which the web displacement bar is spaced apart from a web passing between the blanket cylinder and the impression cylinder, and a second position in which the web displacement bar holds the web in contact with the impression cylinder and spaced apart from the blanket cylinder. A method of operating the press is also provided.
