Popis: | In functional printing, film homogeneity is a key criterion, but there are several phenomena leading to inhomogeneities. We shall focus on the solvent evaporation process of gravure-printed thin films. The best aspects of different published approaches are combined to create a new algorithm for optically determining the film thickness development. In this way, small structures as well as the overall thickness of large-area thin films can be tracked while drying. It becomes clear that the biggest challenge is balancing the camera resolution and frame rate to receive plausible and accurate results. |
