A method of determining clogging characteristics of an apparatus for applying a coating medium to an object, the method comprising:

• conducting air through discharge holes of the apparatus with a first parameter setting, the first parameter setting including flow data indicative of a flow of the air, and clogging data indicative of a degree of clogging of the discharge holes;
• determining a first output air pressure between an air flow regulator of the apparatus and the discharge holes for the first parameter setting, the air flow regulator being arranged to regulate the flow;
• conducting air through the discharge holes with a second parameter setting where at least one of the flow data and the clogging data is different from the first parameter setting;
• determining a second output air pressure between the air flow regulator and the discharge holes for the second parameter setting;
• and
• determining a relationship between a degree of clogging of the discharge holes and the output air pressure based on the flow data of the first and second parameter settings, the clogging data of the first and second parameter settings, the first output air pressure and the second output air pressure.
