Abstract: The disclosure relates to an operating method for a coating system for coating components (e.g. motor vehicle body components) with a coating agent (e.g. paint) by means of an applicator (e.g. rotary atomizer), including the following, The components may be coated with the coating agent, whereby component-related process values are obtained which represent operating variables of devices of the coating system during the coating of the individual components, and whereby a specific component-related coating quality results during the coating of the individual component. Component related process values of the coating system may be determined. Quality relevant anomalies in the process values may be determined. The position of the coating defects corresponding to the anomalies may be determined.

Abstract: In order to provide a method for analysing quality deficiencies of workpieces, preferably vehicle bodies and/or vehicle attachment parts, in particular after and/or whilst passing through a production process in industrial-method plants, preferably after and/or whilst passing through a painting process in painting plants, by means of which method quality deficiencies can be avoided and/or by means of which method quality deficiency causes in the production process can be determined, avoided and/or remedied, it is proposed in accordance with the invention that the method comprises the following steps: creating a workpiece-specific data set, uniquely assigned to a workpiece, at the start of a production process, in particular at the start of a painting process and/or creating a workpiece-carrier-specific data set, uniquely assigned to a workpiece carrier, at the start of a production process, in particular at the start of a painting process; supplementing the workpiece-specific data set while a workpiece is
