A method for producing a security article, the method comprising: printing personalization information on a substrate having a top surface and at least one radiation sensitive layer located within the substrate placing a transparent microlens sheeting on the substrate such that a second broad face of the microlens layer is located proximate to a top surface of the substrate, wherein the transparent microlens sheeting has: at least one transparent layer collectively forming a stack of layers having a first broad face and a second broad face opposite to the first broad face and located on a bottom layer of the stack of layers, the stack of layers comprising one or more layers including: a first transparent layer being a layer of microlenses; the layer of microlenses located on the first broad face of the transparent microlens sheeting and containing a first microlens array and a second microlens array on the first broad face of the transparent microlens sheeting, wherein the first microlens array has a focal plane essentially coplanar to the second broad face and the second microlens array has a focal plane that lies beyond the transparent microlens sheeting; and a first microimage array comprising a plurality of individual at least partially complete images located on the second broad face of the transparent microlens sheeting and associated with each of a plurality of the microlenses of said first microlens array, whereby a composite image, provided by the individual images, appears to the unaided eye to be floating above or below the sheeting, or both when the first microimage array is viewed through first microlens array; and laser engraving a second microimage array through the second microlens array onto the radiation sensitive material such that the second microimage array comprises a plurality of individual at least partially complete images located on the second focal plane and associated with each of a plurality of the microlenses of said second microlens array, whereby a second composite image, provided by the individual images of the second microimage array, appears to the unaided eye to be floating above or below the sheeting, or both when the second microimage array is viewed through the second microlens array, and wherein the step of placing the first microimage under the first portion of the transparent layer follows placing the first translucent layer over the substrate and is performed by laser engraving the first microimage array on the bottom broad face of the transparent layer through the first microlens array. a first transparent layer being a layer of microlenses; the layer of microlenses located on the first broad face of the transparent microlens sheeting and containing a first microlens array and a second microlens array on the first broad face of the transparent microlens sheeting, wherein the first microlens array has a focal plane essentially coplanar to the second broad face and the second microlens array has a focal plane that lies beyond the transparent microlens sheeting; and a first microimage array comprising a plurality of individual at least partially complete images located on the second broad face of the transparent microlens sheeting and associated with each of a plurality of the microlenses of said first microlens array, whereby a composite image, provided by the individual images, appears to the unaided eye to be floating above or below the sheeting, or both when the first microimage array is viewed through first microlens array; and laser engraving a second microimage array through the second microlens array onto the radiation sensitive material such that the second microimage array comprises a plurality of individual at least partially complete images located on the second focal plane and associated with each of a plurality of the microlenses of said second microlens array, whereby a second composite image, provided by the individual images of the second microimage array, appears to the unaided eye to be floating above or below the sheeting, or both when the second microimage array is viewed through the second microlens array, and wherein the step of placing the first microimage under the first portion of the transparent layer follows placing the first translucent layer over the substrate and is performed by laser engraving the first microimage array on the bottom broad face of the transparent layer through the first microlens array.
