The present invention relates to a method for coating, optionally with specific colouring, an exposed surface of a body with simultaneous formation of a structured surface, including projecting formations, via a device for depositing one or more liquid substances in droplets, in particular by a jet, said method consisting, for each affected site (1") of the surface to be printed (1'), of consecutively depositing at least two vertically adjacent layers (6, 6') of a first substance selected from the group made up of a size, a varnish, an adhesion or attachment agent and a coating agent, preferably white or transparent and at least one second substance such as a colouring substance or a mixture of colouring substances, each of the consecutive layers (6, 6') being formed by depositing droplets (4, 4'; 5). The method is characterised in that it consists of consecutively depositing at least three vertically adjacent layers (6, 6') which are made up, alternatively, of a first substance and a second substance, each layer (6, 6') being made up of separate individual droplets (4, 4'; 5), arranged in each layer according to a predetermined pattern. |
