Abstract
A printed dynamic optical illusion printed on a printing device using a plurality of colorants, wherein one or more of the colorants are appearance mutable colorants having spectral characteristics that can be controllably switched between a first colorant state and a second colorant state by application of an appropriate external stimulus, and wherein one or more mutable portions of the optical illusion image are printed using at least one appearance mutable colorant. The mutable portions are controllable such that when they are in a first appearance state the printed optical illusion image has a first illusion state, and when they are in a second appearance state the printed optical illusion image has a second illusion state, thereby changing the optical illusion image from the first illusion state to the second illusion state so as to affect the perception of an optical illusion by a human observer.
