| Résumé : |
In this paper it is demonstrated that it is possible to determinethe dry film thickness via a flatbed scanner at a pixel level throughout the scanned surface. A simple stastitical analysis gives information about the distribution of the thicknesses, grey values and reflectances. It is shown that the results of this statistical analysis can be linked with the intrinsic hiding power and the flow behaviour of the paints, allowing one to quantify the latter. |

- FIGURES : 1. Picture of the drawdown at different film builds and films builds as determined by a profilometer and as calculated by the Kubelka-Munk approach based on reflectances - 2. Roller application on a black substrate, conversion of the visual picture to reflectances (the higher the whiteness, the higher the reflectance), 3D map as calculated by the Kubelka Munk equations and histogram of the thicknesses of the appllied paint - 3. Rollet applications of a ppoor flowing paint A, medium flowing paint B and very good flowing paint C on a black surface. Middle, 3D images of the respective roller applications (area 10x14 cm) and details of the respective 3D images - 4. Histograms of paints A, B and C showing the number of pixels with a certain grey value and histogram of paints A, B and C showing the number of pixels with a certain wet film thickness |
