GRAFI-r: Gravure printing finger instability dataset (raw data)

The GRAFI-r dataset contains high speed videos of finger instabilities during fluid splitting in gravure printing. The high speed videos were recorded on a custom-built gravure printing research platform, which enables optical access to the printing nip. The printing nip is the line of contact between the engraved printing cylinder and the impression roller. The aim of the dataset is the in-situ visualization and temporal analysis of hydrodynamic pattern formation phenomena during fluid transfer. The influence of the engraving raster on the finger instability can be investigated. The GRAFI-r dataset comprises raw video data whereas processed video data can be found in the related GRAFI-p dataset. <br> <br> GRAFI-r dataset stands for <b>gra</b>vure printing <b>f</b>inger <b>i</b>nstability dataset. The suffix -r stands for <b>r</b>aw data. <br> <br> Metadata for the GRAFI-r dataset can be found in the dissertation of Pauline Rothmann-Brumm (2023) and in the provided README-file (last item in dataset, click 'show more').
