A method for applying a pattern of granular material on a receiving surface, comprising in sequence associating said granular material with a transferring surface together with a liquid aggregating phase and according a prefiguration of said pattern; facing said transferring surface carrying said granular material and said liquid phase to said receiving surface in a transferring zone; the method further comprises heating at least one portion of said liquid phase in said transferring zone in order to detach from said transferring surface said granular material and applying the latter on said receiving surface. An apparatus for applying a pattern of granular material on a receiving surface, comprises: a transferring surface movable along a loop path with a transferring zone defined in a portion facing said receiving surface; applying means arranged upstream of said transferring zone , suitable for applying said granular material on said transferring surface together with an aggregating liquid phase and according a prefiguration of said pattern ; the apparatus further comprises heating means suitable for suddenly evaporating in said transferring zone at least one portion of said aggregating liquid phase and thus cause said granular material to detach from said transferring surface and to cause said applying on said receiving surface.
