ABSTRACT:
A method for detecting diffuse reflections of full-tone and half-tone fields in order to prepare diagnoses on problem factors and/or changes in process parameters, such as blurring, dampness, machine temperature. During printing, the diffuse reflections of the full-tone and half-tone fields are detected with scanners. This is done in such a way that for at least two printed copies, in at least two fields of each copy, the diffuse reflections of full-tone and half-tone areas, or of at least two half-tone fields of different area coverages are compared, and based on the results of this comparison, diagnoses and/or control recommendations are made.
