ABSTRACT:
Imaging articles and methods are disclosed that use dual-axis retroreflective elements such as 90 degree prisms and linear lenticular elements in which the imaging is either superimposed on the imaged object or displaced therefrom. If the imaging is superimposed on the imaged object, it is accomplished by retroreflection. If the imaging is displaced from the imaged object, it may be accomplished by dual axis retroreflection or retrotransmission.
