Office Hours in InnovationLab:
Tuesday – Friday
On Mondays: Institute of Printing Science and Technology
My research is about functional gravure printing of organic electronics. My focus is on the doctor blading process which is one of the most important sections in gravure printing. Doctor blading fulfills two important tasks: On the one hand it shall wipe excessive printing fluid off the printing cylinder to fill the printing nips with ink or fluid. On the other hand it shall cover the cylinder surface with a very thin layer of fluid to allow fluid to transfer from the surface to the substrate. In functional printing it is necessary to reach a high level of precision to allow the production of high performance organic electronic devices. For getting an optimal printing process, the doctor blading process plays an important role. During this process, the fluid has to deal with enormous pressures and fluid currents. Material properties of the doctor blade and the printing form influence the process as well. My job is to understand the doctor blading process and to learn how the different parameters influence each other and to get the highest optimization in gravure printing.
