Method for controlling film production

A method for controlling film production, in which at least one film is produced depending on at least one recipe information,

• where the following steps are performed:
• initiating a method execution for film production so that a film is produced based on specific recipe information,
• determination of monitoring information during method execution,
• determining at least one fingerprint from the specific recipe information and from the monitoring information such that the method execution is characterized by the fingerprint,
• comparison of the fingerprint with a control matrix, so that at least one comparison result for controlling film production is determined on the basis of the control matrix as the basis for evaluation,
• wherein the following step is performed after comparing the fingerprint:
• evaluating a quality of at least the method execution or the produced film based on the at least one comparison result, so that an evaluation result is determined, wherein the quality is correlated with a correspondence between at least one determined product property of the produced film and a given product property, whereby the control matrix is specific for the given product property and wherein a high quality corresponds to a high agreement between the determined product property and the given product property,
• wherein the following step is performed after evaluating the quality:
• storing the evaluation result as a function of a roll identifier.
