Method for producing an optimized coating, and coating which can be obtained using said method

A method for producing at least one coating (B1) on a substrate, the method comprising:

• (1) provision of a coating material composition (BZ1),
• (2) determination of at least one characteristic variable of a drop size distribution within a spray formed on atomization of the coating material composition (BZ1) provided as per step (1), and/or of a homogeneity of this spray,
• wherein the homogeneity of the spray corresponds to a ratio of two quotients TT1/TTotal1 and TT2/TTotal2 to one another as a measure of a local distribution of transparent and nontransparent drops at two different positions within the spray, with TT1 corresponding to a number of transparent drops at a first position 1, TT2 corresponding to a number of transparent drops at a second position 2, TTotal1 corresponding to a number of all drops of the spray and hence to a sum total of transparent drops and nontransparent drops at position 1, and TTotal2 corresponding to a number of all drops of the spray and hence to a sum total of transparent drops and nontransparent drops at position 2, with position 1 being nearer to a center of the spray than position 2,
• (3) reduction of the at least one characteristic variable of the drop size distribution and/or homogeneity of the spray formed on atomization of the coating material composition (BZ1), determined as per step (2),
• (4) application of at least the coating material composition (BZ1) obtained after step (3), with reduced characteristic variable of the drop size distribution and/or reduced homogeneity, to a substrate, to form at least one film (F1), and
• (5) physical curing, chemical curing and/or radiation curing at least of at least one film (F1) formed on the substrate by application of the coating material composition (BZ1) as per step (4), to produce the coating (B1) on the substrate.
