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.
