Being part of the Collaborative Research Center SFB 1194 "Interaction between Transport and Processes“, project C01, I deal with flow phenomena in ink splitting. I am especially interested in the phenomenon of viscous fingering which describes the formation of fascinating, finger-like patterns on printed samples. These patterns are often unwanted in printing practice, because they lead to inhomogeneity of the surface. The goal of my research is a better understanding of such phenomena. Therefore, I conduct gravure printing experiments, characterize printing inks and printing forms, digitalize the printed samples with a scanner, evaluate the image data in MATLAB and Python and compare the experimental results for characteristic parameters with predictions from mathematical models. Machine learning and deep learning are also used. Moreover, high-speed imaging of fluid splitting on a specially designed gravure research platform is performed.
