Method for determining spraying parameters for controlling a paint-spraying apparatus using a spraying agent

A method for determining spraying parameters for controlling a paint-spraying apparatus using a spraying agent is disclosed. A known spray pattern is provided which has been determined by means of known spraying parameters for the use of a first spraying agent. A provisional spray pattern is calculated using the known spraying parameters and the characteristics of a second spraying agent. The known spraying parameters are altered in order to acquire changed spraying parameters which yield a further spray pattern. The changed spraying parameters are altered to the point where the further spray pattern is similar to the known spray pattern within a similarity criterion. The changed spraying parameters corresponding to the further spray pattern are intended as spraying parameters for the second spraying agent and are provided to the paint-spraying apparatus whenever the second spraying agent is used. The spraying parameters comprise a plurality of air currents which influence the spraying behavior of the paint-spraying apparatus.
