Abstract: A method for correcting a measurement value of a reference mark on a material web is disclosed. A controller, a machine, a computer program and a computer program product can perform a correction of this type. To improve determination of the position of a reference mark on a material web, a machine in which the material web is moved in a conveying direction has at least one tool that functions in a non-positive locking manner, a second tool that functions in a non-positive locking manner and is located downstream of the first tool in the conveying direction, and a sensor that is located between the two tools. A measurement error in the sensor which arises as a result of an adjustment of the second tool is determined at least approximately at least via parameter values of the second tool. The measurement value is corrected by the measurement error.
