Abstract: Process for selectively and locally treating the surface of a part, wherein—a part having a surface to be treated is provided, said surface being defined by a direction P and a direction Q; —three-dimensional profilometric data are acquired from the surface to be treated, in order to obtain a set F1 of three-dimensional data on the surface to be treated, said set F1 associating a height with each point in the plane PQ; —this set F1 of digital data is processed digitally with a view to subtracting said curves, to obtain a set F2 of reprocessed three-dimensional data; —this set F2 of data is processed digitally, to obtain a set F3 of binary data on the surface to be treated, said digital processing attributing, to each point on the surface, a first binary value or a second binary value, depending on at least one criterion related to the height of the point on the surface; —the surface is selectively and locally treated using said set F3 of binary data, said surface treatment being performed only at points on the surface the binary datum of which has said first or said second binary value.

Abstract: Inkjet printing module (1) capable of being picked up by the arm (111) of a robot (101), characterized in that said module includes: a print head (2); an ink reservoir (3) capable of supplying ink to said print head (2); compressed-gas supply means (4) capable of suppling compressed gas to said print head (2); a mechanical interface (7) capable of engaging removably with a complementary mechanical interface (107) of a robot arm; an electronic interface (6) capable of engaging removably with an electronic interface (106) of said robot arm in order to transfer data between said module and the robot; and at least one fluid interface (5) placed in fluid communication with the compressed-gas supply means or with the ink reservoir.
