The ink drop fixing method has a preliminary stage of applying an ultraviolet beam (32) concentrated on the ink drops (31) on the surface, avoiding exposure of the plastic support (30) for the printing. The ink drops are deposited point-by-point on the surface. The ink is made of a material that is polymerisable under ultra-violet radiation. The ultra-violet radiation is provided by an ultra-violet laser (43), which is swept point-by-point across the printed surface. The ultra-violet beam is directed by an optic fibre (71) of a network (70) of optic fibres. The beam is interrupted when it is directed toward the un-inked surface. |
