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, wherein the material layer comprises a first side and a second side opposite the first side, and wherein the second side is 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 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 an unaided eye to float above or below the sheeting, or both;a second composite image, provided by at least one of the individual images, that appears to an aided eye to float above, in, or below the sheeting, or any combination thereof,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, and wherein the second composite image includes micrographics. 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 positive 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 negative contrast second composite images. 5. The sheeting of claim 1, wherein the first composite image also appears to the unaided eye to be at least in part in the plane of the sheeting. 6. The sheeting of claim 1, wherein the first donor material comprises radiation sensitive material. 7. 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. 8. The sheeting of claim 1, wherein the second composite image is an angularly variable array of images. 9. The sheeting of claim 8, wherein the second composite image appears to scroll relative to the sheeting. 10. The sheeting of claim 1, wherein the eye is aided by magnification. 11. The sheeting of claim 10, wherein the second composite image is vieweable under magnification. 12. A method of forming two composite images on a microlens sheeting, comprising the steps of: providing a sheeting having an array of microlenses and a material layer adjacent the array of microlenses, wherein the material layer comprises a first side and a second side opposite the first side, and wherein the second side is adjacent the array of microlenses;providing a mask adjacent the array of microlenses of the sheeting;providing a first donor substrate adjacent the material layer of the sheeting, wherein the first donor substrate is radiation sensitive, and wherein the first donor substrate comprises a colorant;providing a radiation source; transferring at least a portion of the first donor substrate to the sheeting using the radiation source and the mask to form at least two individual, partially complete images on the material layer associated with each of a plurality of the microlenses, whereby the sheeting exhibits a first composite image, provided by at least one of the individual images, that appears to an unaided eye to float above or below the sheeting, or any combination thereof, wherein the sheeting exhibits a second composite image, provided by at least one of the individual images, that appears to an aided eye to float above, in, or below the sheeting, or any combination thereof, and wherein at least a portion of the first or second composite image exhibits a color similar to the colorant in the first donor substrate, and wherein the second composite image includes micrographics. 13. The method of claim 12 further comprising the step of: removing the first donor substrate;providing a second donor substrate adjacent the material layer of the sheeting, wherein the second donor substrate is radiation sensitive; andrepeating the transferring step with the second donor substrate. 14. The method of claim 13, wherein the second donor substrate comprises a colorant different from the colorant of the first donor substrate. 15. The method of claim 12, wherein the first composite image also appears to be at least in part in the plane of the sheeting. 16. The method of claim 12, wherein the mask assists in forming either positive contrast or negative contrast second composite images. 17. The method of claim 12, wherein the second composite image is an angularly variable array of images. 18. The method of claim 17, wherein the second composite image appears to scroll relative to the sheeting. 19. The method of claim 12, wherein the eye is aided by magnification, and wherein the second composite image is vieweable under magnification. 20. The method of claim 12, wherein the eye is aided by a viewer having specific wavelengths of light, and wherein the second composite image is viewable using the specific wavelengths of light. 21. The method of claim 12, wherein the transferring step transfers portions of the first donor material to the first side of the material layer.
