METHOD OF CREATION ON SHEET MATERIAL OF IRIDESCENT IMAGE, AND SHEET MATERIAL FOR ITS IMPLEMENTATION |
摘要 |
FIELD: printing.SUBSTANCE: invention relates to special types of printing enabling to create in the body of the sheet material the original image protecting it against forgery. The method of creation on the sheet material of the iridescent image consists in the impact on the image applied on the sheet material with the light flux reflected from the diffraction grating at different angles of its rotation. In the body of the sheet material the image of isolated points in the form of volumetric extended metal-dielectric nanostructures with quantum size effects is created and placed it between the metal layer and the reflective diffraction grating. At that over each point of the image in the metal layer an opening is made through which the light flux is directed to the diffraction grating.EFFECT: proposed invention provides a bright image providing protection of the sheet material against forgery.9 cl, 5 dwg |
