From the description of the patent (see (19) RU (11) 91716, (13) U1, (51) IPC SS 27/12, (2006.01), (54) multi-layer COMPOSITION) known multi-layer composition, which refers to translucent, mostly decorative multi-layer compositions of the glass. Multi-layer composition includes glass, between which is placed at least one bonding layer and single layer film and/or fabric, which is the carrier of the image caused printing method. The surface of each glass embossed to create three-dimensional images, the shape and contours of the relief surfaces of glass match each other and the image on the film and/or fabric. Embossed glass surface formed concave or convex or plane-parallel multilevel sites or their combination and has a variable thickness. Each layer of the film and/or fabric consists of separate pieces. The image can be also applied to the relief surface of the glass.
The disadvantage of this technical solution is that the claimed relief image complex in the manufacture, as to thetsa create a concave or convex or plane-parallel multilevel sites or their combinations.
It is known device for the formation of images (see patent RU (11), 105507 (13), U1 (51), IPC G09F 19/00, (2006.01) (54) device for the formation of the IMAGE). The device forming the image contains media information printed on its surface the image storage medium is executed in the form of a metallic sheet, the surface of which is coated with the image in the form of through open holes arbitrary configuration with a protruding element, which is made to rotate and/or tilt under any set of positive and/or negative angle relative to the sheet metal surface.

Function base layer is reflected from the top surface of the base of the rays that fall from above the light guide and the light-scattering layer.
On the light guide layer, which may be made of plastic or glass (most often made of acrylic glass), laser marked.
The function of this layer is to deliver with minimal loss of light from the source/s of light to the grooves engraved on the surface of the plate, so that they, in turn, has been focusing delivered to them the light and redirected it into the light diffusing plate.
Engraving can be performed either on the entire surface or only on the part of the surface layer, which is located under the surface area, require greater illumination. The recesses in the glass act as a lens, focusing the rays and changing the direction of their propagation.
