METHOD OF MAKING PROTECTIVE HOLOGRAM

摘要

FIELD: marking of data carrier by means of protective hologram. ^ SUBSTANCE: method is based upon making necessary image, recording of hologram from the latter, creating of metal array from the hologram and subsequent reprinting of protective hologram along the surface of polymeric film by means of stamping the array onto it. Before making the array for reprinting holographic images of necessary image composed by set of images, the operation of making common metal array is conducted from any single holographic image and mirror image being like necessary one is recovered. ^ EFFECT: improved adaptability to manufacture. ^ 5 dwg
