An instrument is described for measuring the thickness of a paint coating on a rotating roll of a roll coating applicator roll for determination of the thickness of a paint coating to be applied to a moving substrate comprising: sensor means arranged for emitting and detecting signals reflected from the surface of the paint coating on at least one roll of the roll coating applicator to generate data indicative of the position of the surface of the paint on the roll, the sensor means being distanced from the paint coating for the emission and detection of the signals; and processing means for processing the data generated by the sensor means to determine the thickness of the paint coating to be applied to the substrate. |
