Process for the determination of controlled variables for the inking unit of printing presses

摘要

A process which makes possible a zonal ink control with the use of print control strips with single, double, or multizone repetition cycle of the measurement fields, and by means of which controlled variables can also be determined according to measurement strips without zonal separation for all ink zones. Substitute measurement values are formed by interpolation for each ink zone from determined measurements and from their lateral position in relation to the corresponding ink zones, and these substitute measurements are compared with setpoints, and the difference is used to determine controlled variables.
