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 (27) 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 (26 and 32) 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 (29) downstream of the etching roller (27) 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 (R1) and the post-creep radius (R2).
A printing method for obtaining a precision structure including protruding regions and recessed regions, of which a smallest radius of curvature (R2) of the protruding regions is less than 200 μm, on at least one of the faces of a flat glass advancing continuously at a rate of at least 1 m/min, using a structured tool having surface imprints, wherein:
