摘要
At least one complete surface of at least one metallic part of a can is given a uniform coating of corrosion-preventing lacquer and this part is subsequently worked such that the metal of the part is exposed at regions at least immediately adjacent the coated surface. Dots of lacquer are sprayed by the ink-jet method substantially only on the exposed regions of the part after working thereof and so that the dots together form a continuous layer covering the exposed regions. According to the viscosity of the lacquer the surface coating can be achieved by partially overlapping adjacent dots of the applied lacquer or without overlapping by the running together of the adjacent dots of the liquid, with no excess material having to be applied to and subsequently removed from the regions to be coated.
