Abstract

Optical density modulation is provided by projecting light through an imaged member 10 having a layer 12 of partially transparent, deforma)Dle material containing dye, pigment or other light absorbent material 13~ The image comprises portions 14, ~5 and 16 of the deformable material layer having different thicknesses to thereby differentially modulate light transmitted therethrough. An optional sub- strate 11 is typically provided during deformation imaging of layer 12 and in replicating the deformation image by contacting same with another layer of softenable materia1~
