Abstract
Process and apparatus for measuring optical, especially calorimetric, parameters on liquid, colored media, especially on wet lacquers, in which the liquid, colored medium is applied to a continuously moving, cylindrical support, a film of the liquid, colored medium forms on the continuously moving, cylindrical support, and optical, especially calorimetric, parameters are measured on the film of the liquid, colored medium.
Claims10
Process for measuring optical parameters on liquid, coloured media, characterised in that the liquid, coloured medium is applied to a continuously moving cylindrical support, a film of the liquid, coloured medium forms on the continuously moving cylindrical support, and optical parameters are measured on the film of the liquid, coloured medium using conventional optical measuring devices.
Process according to any one of the preceding claims, characterised in that the liquid, coloured media measured are liquid lacquers.
Process according to any one of the preceding claims, characterised in that the measurement is carried out on the moving or stationary cylindrical support.
Process according to any one of the preceding claims, characterised in that the cylindrical support is arranged horizontally or vertically in front of the measuring device.
Process according to any one of the preceding claims, characterised in that, once a uniform, bubble-free film has formed on the surface of the cylindrical support, the cylindrical support is brought up to the measuring aperture of the measuring device.
