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.

We claim: 1. A method of forming two composite images on a microlens sheeting, comprising the steps of:providing a sheeting having a plurality of microlenses and a material layer adjacent the plurality of microlenses;providing a first donor substrate adjacent the material layer of the sheeting, wherein the first donor substrate is radiation sensitive;providing a radiation source;transferring at least a portion of the first donor substrate to the sheeting using the radiation source to form individual, partially complete images on the material layer associated with each of the plurality of the microlenses, whereby the sheeting exhibits a first composite image, provided by the individual images, that appears to the unaided eye to float above, in, or below the sheeting;thereafter removing selected portions of the individual, partially complete images using the radiation source to form a second composite image, provided by the individual images, that appears to the aided eye to float above, in, or below the sheeting.
