Abstract
A method for printing a precision structure on the surface of a glass strip advancing continuously at a rate of at least 1 m/min, using an etching roller () applying a printing force against the surface to be etched, the structure to be produced including protruding and recessed regions which have radii of curvature, a preliminary thermal conditioning (and) being performed upstream of the etching roller; the thermal conditioning is designed to ensure a temperature of the strip (J) over the print thickness and a cooling () downstream of the etching roller () to ensure a controlled fixing of the structure; the method according to the invention making it possible to determine the parameters that are intimately linked for obtaining a particular structure, notably the print temperature, the printing force and the cooling rate, taking into account a degree of creep between the molding radius (R) and the post-creep radius (R).
