Definitions
- the invention relates to the field of protection against counterfeiting of printing products, including plastic and paper: banknotes, securities, documents, passport pages, certificates, bank cards.
- the basis for the formation of security features is the use of multilayer transparent elements in which rasterized images are formed on spatially separated surfaces of the transparent layers.
- various optical effects formed by the moire addition of elements recorded in different layers of images are possible.
- the closest analogue of the claimed invention is the solution described in patent RU 2503767, 01/10/2014.
- a transparent or translucent information carrier is proposed, which is protected from counterfeiting by printing methods on one side of the image carrier, rasterized with periodic linear elements in the form of a lattice with a given period and line thickness, and on the other side of the medium - a uniform linear raster with the same period and line thickness .
- the thickness and orientation of the lines of the raster lattice in the rasterized image on the first side of the medium and the lattice of a uniform raster on the opposite second side of the medium are the same, but the lattice in the image and the raster is spatially shifted relative to each other by a distance less than the spatial period of the raster lattices. This distance is selected in such a way that when the viewing angle is changed, the contrast of the observed image formed on the first side of the medium changes.
- a disadvantage of the known technical solution is that when the viewing angle is changed, only the contrast of the visually observed image formed on the first side of the protective element carrier changes, which limits the possibility of recognizing the protective element.
- the degree of change in the contrast of the image of the security element during the circulation of the printed product may vary for various reasons, and determining the authenticity of the products becomes difficult.
- the problem solved by the invention is to increase the degree of security of printing products and valuable documents.
- a multilayer transparent structure contains two different rasterized images located in one layer, and a linear raster is made in the other layer, and these layers are spaced from each other at a distance determined by the resolution of the rasterized images, while when viewing the protective element in light or reflection at different angles, they are alternately visible various images.
- Rasterized images can be printed, embossed, by exposure to optical radiation in a photosensitive layer. Rasterized images can be portrait or other identification images.
- Rasterized images can be graphical symbols, or geometric shapes, or text.
- the layers can be made of polymeric, paper or composite materials.
- One or more rasterized images can be made using dyes of different colors.
- FIG. 1 shows the layers of the claimed security element with rasterized images.
- FIG. 2 shows a diagram of the passage of light through the claimed protective element when viewing it at different viewing angles.
- the spatial periods and the orientation of the raster gratings in the images of the first layer should be the same and must coincide with the spatial period and the orientation of the raster formed in the second layer.
- the spatial shift and duty cycle of the raster gratings in the generated images should be different. They will determine the degree of visibility of images observed in the light at a certain angle to the surface of the medium. As the viewing angle changes, the contrast of the observed images will change. One image will appear and the other will disappear.
- FIG. 1 shows a multilayer structure consisting of two transparent layers 1 and 2, placed one above the other at a certain distance h.
- the images of circle 3 and square 4 are formed on the upper surface of layer 1 .
- the spatial period d of the raster lattices 5 and 6 is the same in both images.
- Symmetric linear raster gratings are shown with a line width L equal to half the grating period d. In the general case, gratings can also be asymmetric.
- the spatial period and orientation of the raster lattices are the same and coincide with the spatial period and orientation of the raster lattice 7 formed on the lower side of layer 2.
- the rasterized images formed on layer 1 will be to be visualized with different contrast depending on the direction of observation and the magnitude of the spatial displacements ⁇ 5 and ⁇ 6 respectively of the screening gratings 5 and 6 in the images of circle 3 of square 4.
- P the spatial spatial displacements of the lattices are determined by their displacement relative to the raster lattice 7 on the lower side of layer 2.
- the spatial period of the raster lattices should not exceed 100 ⁇ m (as a rule, it lies in the region of 20–50 ⁇ m).
- the human eye practically does not distinguish between the periodic structure of rasters.
- applying raster gratings 5 and 6 in images 3 and 4 on layer 1 and lattice 7 raster on the lower surface of the layer 2 is their moiré addition.
- FIG. 2 shows the passage of light through a screening grid 5 of the image of a circle 3 when
- the grating 5 is located above the grating 7 of the raster formed on the layer 2.
- the spatial displacement of the grating 5 relative to the grating 7 is ⁇ 5 .
- the problem is solved when, when the viewing angle is changed, the image itself changes, and not just its contrast.
- Using colored paints when rasterizing images it is possible to obtain the effects of the appearance and disappearance of images when changing the direction of observation, as well as the effects of changes in both color and contrast.
- With the right choice of the parameters of the raster gratings it is possible to form not only spatially separated images, as shown in this example implementation of the present invention, but also to form them by practically superimposed images with a slight displacement of the raster gratings.
- the saturation (optical density) of the linear elements of the gratings and the duty cycle of the gratings can vary over the area of the images, which allows visualization of grayscale images.
- the invention is applicable in the field of protection against counterfeiting of printing products, including plastic and paper: banknotes, securities, documents, passport pages, certificates, bank cards.
