Abstract: A method applying a bead of a coating product to a surface by a print head equipped with nozzles, each centered on a central axis, the coating product application moves the print head and the surface relative to each other, by moving the print head along a fixed trajectory relative to the surface without rotating the print head about an axis parallel to the central axes of the nozzles. The method includes selecting certain nozzles for a point of the trajectory based on the trajectory direction at this point, and activating the selected nozzles at this point. The selected nozzles are arranged in a line, or form part of a nozzle group delimited by a line, whose regression line coincides with a line as close as possible to a line perpendicular to the trajectory direction from among lines that can be defined with nozzles of the print head.

Abstract: This method for painting a surface (S62) of a component (6) with a pattern includes at least the following steps consisting in applying a first coating product on at least a portion of the surface, automatically applying at least one portion of a mask (12) on a portion (Z62) of the surface, applying a second coating product and on the surface and removing the mask (12). Preferably, the mask (12) is at least partially automatically applied in the form of at least one layer (122, 124, 126) of non-atomized fluid, the layer being obtained by moving (A1) an applicator (16) delivering the non-atomized fluid along the portion (Z62) of the surface (S62) where the mask (12) is to be applied.
