Examples include a device for aligning magnetic or magnetizable particles contained in a coating agent applied to one side of a web-format or sheet-format substrate. An alignment device comprises one or more magnetic elements that, during normal operation, are fixed to a frame at the transport path and, in a working position, enter into magnetic interaction with magnetic or magnetizable particles on the substrate guided past the device along the transport path. The one or more magnetic elements are arranged at a carrier that extends transversely to the transport direction over a working width provided for processing the substrate. The carrier is mounted, on both sides, in or at a respective guide and can be moved in or at the guide, together with the one or more magnetic elements, along a movement path from the working position into a makeready position.

A system including a non-contact plate sensor and a processor configured to characterize a configuration of a plate based upon information received from the sensor, such as position on a press or plate quality. The processor is configured to initiate a responsive action based upon the characterized configuration. A related method includes setting pressure of a printing plate relative to an ink-receiving substrate and register of a printing plate relative to another printing plate on a press, without generating printed waste. The non-contact plate sensor measures a distance of the printing surface of the plate relative to the sensor in locations along the plate longitudinal axis to characterize a starting configuration of the plate. The plate longitudinal axis is adjusted to correspond with a desired position of the plate for exerting a desired pressure on the substrate, based upon a difference between the measured starting position and the desired position.
