1. A method for coating components, the method comprising:
performing a testing operation for quality assurance,
wherein the testing operation comprises:
a) specifying a test pattern to be applied to a test surface,
b) determining control signals for controlling a coating system with an applicator guided by a coating robot, wherein the control signals
b1) are determined from the predetermined test pattern, and
b2) are intended to control the coating system in operation in such a way that the applicator applies the test pattern to the test surface,
c) applying the test pattern with the applicator to the test surface by controlling the coating system with the control signals,
d) recording an image of the test pattern applied to the test surface by means of a sensor,
e) determining a deviation between the predetermined test pattern and the recorded image of the actually applied test pattern, and
f) determining correction values for the control signals as a function of the deviation between the predetermined test pattern and the recorded image of the actually applied test pattern, and
g) wherein individual coating agent jets either consist of separate coating agent droplets or are coherent in the jet direction.
