Microlens sheetings with different types of composite images are disclosed, in which the composite image floats above, in, or below the sheeting, or some combination. One type of composite image may be viewable to the unaided eye or an observer and another type of composite image is viewable only to the aided eye of an observer. Methods for providing such an imaged sheeting are also disclosed.

1. A sheeting comprising: an array of microlenses;a material layer adjacent the array of microlenses;a first donor material in contact with the material layer, wherein the donor material forms at least two individual, partially complete images formed on the material layer associated with each of a plurality of the microlenses;a first composite image, provided by at least one of the individual images, that appears to the unaided eye to float above or below the sheeting, or any combination thereof;a second composite image, provided by at least one of the individual images, that appears to the aided eye to float above, in, or below the sheeting, or any combination thereof, wherein the at least one of the individual, partially complete images includes a gaseous void. 2. The sheeting of claim 1, wherein the second composite image is aligned with the first composite image. 3. The sheeting of claim 1, wherein the individual, partially complete images on the material layer associated with each of a plurality of the microlenses form negative contrast second composite images. 4. The sheeting of claim 1, wherein the individual, partially complete images on the material layer associated with each of a plurality of the microlenses form positive contrast second composite images. 5. The sheeting of claim 1, wherein the first donor material comprises a colorant, wherein at least a portion of the first or second composite image exhibits a color similar to the colorant in the first donor material. 6. The sheeting of claim 1, wherein the first or second composite image appears under reflected light or transmitted light to float above the sheeting. 7. The sheeting of claim 1, wherein the first or second composite image appears under reflected light or transmitted light to float below the sheeting. 8. The sheeting of claim 1, wherein the first composite image also appears to be at least in part in the plane of the sheeting. 9. The sheeting of claim 8, wherein the first composite image is a three-dimensional image. 10. The sheeting of claim 1, wherein the second composite image appears substantially to float only in the plane of the sheeting. 11. The sheeting of claim 1, wherein the donor material comprises radiation sensitive material. 12. The sheeting of claim 1, wherein the second composite image appears to move relative to the sheeting as the viewing position changes relative to the sheeting. 13. The sheeting of claim 1, wherein the second composite image is an angularly variable array of images. 14. The sheeting of claim 13, wherein the second composite image appears to scroll relative to the sheeting. 15. The sheeting of claim 1, wherein the sheeting is adhered to a substrate, and wherein the substrate is a document, a sign, an identification card, a container, a display, a credit card, or wherein the sheeting is used for advertising, decoration, authentication or identification purposes.
