Abstract
A method for setting a drop shape in a printing process, including the steps of controlling (S101) a piezo element of a printing nozzle by a first voltage profile; detecting (S102) an electric current value averaged over the first voltage profile or a sound amplitude averaged over the first voltage profile; controlling (S103) the piezo element of the printing nozzle by a second voltage profile; detecting (S104) an electric current value averaged over the second voltage profile or a sound amplitude averaged over the second voltage profile; and selecting (S105) the voltage profile with the lower detected current value or the lower detected sound amplitude.
