Abstract: The invention relates to a reflective feature, e.g., reflective security feature or reflective decorative feature, comprising a first element at least partially coplanar with a second element. The first element causes incident light to be reflected with a first intensity that varies as the angle of incidence changes relative to a surface of the reflective feature. The invention also relates to a direct write printing process for forming such a reflective feature from an ink comprising metallic nanoparticles.
