Forced Wetting of Surfaces by Gravure Printing Cylinders


C01 investigates wetting and dewetting in gravure printing. The subject of the study is the extremely fast wetting dynamics of fluid bridges during ink splitting in the gravure printing process, as well as pattern formation phenomena of the liquid-gas interface during fluid splitting. The focus is on simple, Newtonian as well as complex, shear-thinning fluid mixtures and solutions. The fluid splitting in the printing gap is considered in conjunction with the doctor blade process, which introduces the pressurised fluid into the engravings of the gravure cylinder.

High-speed video recordings of these processes, which are carried out together with A03 , create the experimental data basis for the evaluation of different simulation strategies of the fluid splitting and wetting process with OpenFOAM, among others, which are carried out with the projects B01 , B04 , B06 and B07 .
