ABSTRACT:
In a picture-element-by-picture-element and picture-line-by-picture-line recording of printing forms, at least two picture signal sequences are acquired, and the picture signal sequences are influenced by mask signals. A recording signal sequence for the control of a recording element for the printing form is generated with the assistance of the influenced picture signal sequences. A signal sequence is acquired from every picture signal sequence, this signal sequence containing the picture signal values of the corresponding picture sequence to be recorded for picture elements lying within a sub-area of the printing form to be recorded and in which the picture signal values of the corresponding picture signal sequence which are not to be recorded for picture elements lying outside of the sub-area are respectively replaced by a mask signal value. The signal sequences are combined to form a resulting signal sequence. The possible signal value combinations of the resulting signal sequence have recording signal values allocated to them, which, during recording of the printing form, are called in by the respective signal value combinations as a recording signal sequence.
