1. A coating process for coating components with a coating agent, the coating process comprising the following steps:
a) moving a first printhead with at least one nozzle and an associated printhead valve by means of a multi-axis coating robot over a surface of the component to be coated, and
b) discharging a coating agent jet of a first coating agent through the nozzle of the first printhead onto the surface of the component to be coated,
c) a color change with the following step: exchanging the first printhead by a second printhead for the subsequent delivery of a coating agent jet of a second coating agent through the second printhead onto the surface of the component to be coated, including depositing the first printhead from the coating robot in a deposit device and taking-up the second printhead by the coating robot,
d) circulating coating agent and/or rinsing agent through the deposited first and second printheads, respectively, in the deposit device to prevent the coating agent from drying in the deposited first and second printheads.
