An inkjet printing machine for printing individual sheets comprises at least one printing station and a transport system defining a transport track () for transporting the individual sheets through the printing station, along a transport direction. The transport system comprises a plurality of gripper conveyors () running along the transport track () for holding the individual sheets during a printing process in the printing station. At least one of the plurality of gripper conveyors () comprises a gripper mechanism () for gripping a leading edge of one of the individual sheets and at least one of the plurality of gripper conveyors comprises a gripper mechanism () for gripping a trailing edge of the individual sheet. The transport system further comprises a linear motor () being controllable in such a way that movement of each of the gripper conveyors () along the transport track () is individually controllable. The printing machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.

The transport system comprises a plurality of gripper conveyors () running along the transport track for holding the individual sheets during a printing process in the printing station. Each of the gripper conveyors () comprises an energy storage () for providing energy for operating a gripper mechanism () of the gripper conveyor (). The printing machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.

A suction box, intended for a system for transporting flat media () includes at least one endless belt (), formed with a plurality of through-holes, in a media-printing machine (), equipped with at least one printing unit (). The suction box has a face () past which the belt () passes. A suction device () generates a vacuum in the suction box. The face () of the suction box is formed with at least one zone at a first suction pressure (), which is in communication with the suction device (), so as to apply the vacuum through the holes in the belt () to the media being transported by the belt (), and the face of the suction box has at least one zone at a second pressure (). The zone at a second pressure is situated in the region of the printing unit (). The magnitude of the second pressure is greater than the magnitude of the first pressure.
