<p>The invention relates to a method and an arrangement for controlling cross machine properties. A high resolution profile of a property is measured by measuring N points in the cross direction at two instants. A high resolution error profile of a property is formed by comparing the measured profile with the high resolution desired profile. A high resolution enhanced error profile comprising N spatial values is formed by subjecting the formed error profiles to a time-domain enhancement operation. Alternatively, a high resolution enhanced measured profile and a high resolution enhanced desired profile are formed by subjecting the profiles to a time-domain enhancement operation. Thereafter, a high resolution enhanced error profile of a property comprising N spatial values is formed by comparing the enhanced measured profile of each property with the enhanced desired profile. In order to control actuators, M actuator control signals are formed from the high resolution enhanced error profile comprising N spatial values, where M and N are positive integers greater than zero, M < N.</p> |
