Abstract

A new fast objective method has been developed for the measurement of image clarity of coated steel sheet utilizing an image analyzer. Image clarity is considered as the overall impression of the paint appearance. Two distinct features which contribute to the perception are recognized: short-term waviness (contrast) and long-term waviness (orange peel). This report describes how the Hoogovens (HO)-method registers image clarity and how then both aspects are analysed. For automotive applications, a comparison is made between the results of the HO-method versus the outcome of visual perception, manual assessment methods and instrumental assessment methods. With the HO-method the paint appearance of domestic appliances can also be determined.
