ABSTRACT:
A new technique and apparatus for printing that includes the formation of a hologram, or other type of diffraction pattern, directly on a desired end product of paper, or other sheet material. The hologram, or other diffraction pattern, is formed by casting a surface relief pattern directly onto the sheet material in a limited area.
