Abstract: The present invention relates to a method for surface-treating a part (2), comprising: a measurement step, during which movement means (3), to which the part (2) is secured, are moved and a set of instantaneous velocities, at the surface (1) of the part (2), is determined by means of a measurement sensor (9), a signal processing step, during which a microcontroller (8) determines, from the data representative of the set of instantaneous velocities, a pulse train signal (S) representative of a set of frequencies of ejection of a substance (13) to be deposited, a deposition step, during which the microcontroller (8) transmits the pulse train signal (S) to the deposition means (6) in order to eject the substance (13) according to the pulse train signal (S).

Abstract: The present invention concerns a facility (1) for printing surfaces of parts comprising: —apart support (3) mounted on a movement device (4) having at least five degrees of freedom, —at least one spray printing head and means (8) for sensing speeds and/or coordinates mounted on a support (11), —means (10) capable of controlling the printing means and the movement device (4), the movement device (4) and the support (11) being arranged opposite each other and a spatial reference frame (X, Y, Z) being assigned to said fixed support structure (11). A printing facility (1) characterised in that the printing means (5) consist of at least two monochromatic or bi-chromatic printing heads that are able to rotate and/or move in translation with at least one degree of freedom.

Abstract: The present invention concerns an installation for printing and drying a part having a surface. The installation includes a printing means comprising a printhead, a control unit, a support device suitable and intended for supporting the part, the support device and printhead being movable relative to each other, drying means including a source and an emission output, the emission output and support device being movable relative to each other, and means for adjusting and orienting the beam specifically associated with the source and/or with emission output.

Abstract: 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).
