Abstract: The invention relates to a method for automated error management in a printing machine, wherein a recurring print image is imprinted on a moving material web. To improve automated error management for existing inspection systems, the invention provides a method wherein the print image is acquired by a line scan camera and forwarded to a control unit, in which a print error is recognized in the acquired print image, using an error recognition algorithm, and is saved by the control unit together with a position information and a status information. The position includes at least the margin position of the print error on the material web, and a plurality of recognized print errors are entered by the control unit in a cluster image depending on the position information and the status information, wherein the control unit recognizes an error cluster and error cluster information is output via the error cluster.

Abstract: The invention relates to a drying device (10) for a drying between inking units of a printing machine (1), with which a substrate (2) can be transported via rotating cylinders (3.1, 3.2, 3.3) and is printable with a coloring agent (4), with an air supply unit (11) for supplying of air (5) in direction of the substrate (2) in order to effect a drying of the coloring agent (4), a suction unit (12) for discharging the air (5), a control unit (20), which controls and/or regulates the air supply unit (11) in dependence of the operating parameters (B) in a way that altering drying areas (13.1, 13.2, 13.3) are adjustable at the substrate (2).
