The method of obtaining image

 

(57) Abstract:

A method of obtaining images to improve image quality lies in the fact that simultaneously with the formation on the carrier main raster carry out the formation of additional raster from the core, out of one or both axes by the amount of the portion of the period of the primary raster and formed on the additional raster form an additional image. 6 C.p. f-crystals, 8 ill.

The invention relates to a method of obtaining images, in particular a latent image.

A method of obtaining images, consisting in the formation of the carrier main line of the raster with the period, less the original image, to allow the placement of multiple periods raster (patent England N1041639, CL 44 F 1/10, 07.09.66, is similar and prototype).

The disadvantage of this method is the low quality of the received image.

The technical result of the invention is to improve image quality, and it is hidden.

This is achieved by the fact that in the method of obtaining images, consisting in the formation of the carrier main screen p raster, unlike the prototype simultaneously with the formation on the carrier main raster carry out the formation of additional raster from the core, out of one or both axes by the amount of the portion of the period of the basic raster formed on the additional raster form an additional image that represents the intersection of the original hidden image with an additional image, followed by placement of additional images in the remote place of the main image on the main raster, and after the formation of the last image, perform the obtaining of the latent image by imposing on it the primary raster.

And also the fact that after receiving the latent image carried out positive or negative developed image by superimposing on the latent image of the main pattern for various shifts.

And also the fact that when receiving a latent image on a uniform background, the primary raster form in black and white raster.

And also the fact that when receiving a latent image on the background of the visible image base raster form by eliminating visible izobretennyh rings.

And the fact that the primary raster before applying on the last image rotate, preferably 90o.

The method of obtaining images is illustrated by drawings, where:

Fig. 1 - formation of basic linear black-and-white raster with the original image:

Fig. 2 - placing the original image and its subsequent removal;

Fig. 3 - the formation of additional linear screen, out of 1/8 of the period of the basic raster;

Fig. 4 - the formation of the additional image;

Fig. 5 - extra image in a place remote from the main primary source raster image;

Fig. 6 - formation of the latent image;

Fig. 7 is superimposed on the latent image of the primary raster and visualization of the latent image;

Fig. 8 - formation of the primary image with the visible image.

The method of obtaining image is education on the media (not shown) of the primary, for example linear, raster 1 with the period, the smaller the size of the original image 2, to allow the placement of multiple periods of the raster.

Simultaneously with the formation on the carrier main raster 1 sustinet on value (Fig.3 - 1/8), part of the main period of the raster 1, formed on the additional raster form an additional 3 image 4, represents the intersection of the original image 2, with an additional raster 3, followed by placement of additional images 4 in place of the remote primary source image 2 on the primary raster 1.

After the formation of the additional image 5 is carried out imposing rotated, for example 90othe primary raster 1?, for the formation of the latent image 6. After the formation of the latent image 6 to increase the effect of stealth carry out overlay on the last primary raster 1 or more raster 3, out of half of the period corresponding to the coordinate axes to obtain a developed image 7.

To get on the same field hidden and non-hidden images, including hidden on the background visible, the main source raster form 1 with the exception of the visible image 8 raster 1, thus obtaining the image 9, and use it to create a latent image by applying the image 5 instead of a rotated raster 1, and the latent image appears of the image in terms of its stealth.

Industrial applicability.

The invention can be used to create images on the seals, stamps, stamps, money, etc.,

FIELD: manufacture of multi-layered films with optical effects, and also decorative products, covered in multi-layered film.

SUBSTANCE: multi-layered film for manufacture of decorated product, which contains a base decorated by multi-layered film with curved sections of surface, represents IMD-film or film, usable for deep stretching, which is made with possible deformation during manufacture of decorated product to match the curvature of base of decorated product. The IMD-film or deep stretching-compatible film contains a transparent structural layer with spatial structure which creates a visually perceptible effect and a deflecting layer, positioned in direction of viewing under the structural layer. The decorated product, in particular, Handy-cover or Handy-window, contains a base with curved sections of surface and at least one decorative element, positioned in the area of one or several curvatures of base surface. The decorative element is composed of multi-layered film, which during manufacture of the base is deformed to match one or several curvatures.

EFFECT: possible creation of stable image without distortions, on sections, where the base has curvatures of surface.

FIELD: printing.

SUBSTANCE: optical raster is used, which posterior surface coincides with the focal plane of the optical elements of the raster. The spatial separation of images belonging to the group of images that form the parallax panoramagram or vario-image is carried out by sequential ablation of sites of posterior surface of the optical raster, on which in turn the images are printed belonging to the group of images that form the parallax panoramagram or vario-image.

EFFECT: exclusion of the dependence between the maximum number of images, from which panoramagram or vario-image is formed and resolution capability of a particular type of printing.

SUBSTANCE: proposed element comprises first and second optically variable element including the first and second optically variable thin-film laminar interference devices. Note here that said the first and second optically variable thin-film laminar interference devices are located so that they can be viewed together. The band covered by second device 3rd and 4th lengths waves lies in the band covered by first device 1st and 2nd lengths waves. This allows determination of definite light incidence angle whereat peaks of k-order of reflection of said 1st and 2nd interference coincide. Said 1st and 2nd optically variable interference devices feature identical interference structures so that they display true spectral matching at said preset light incidence angle while at other angles they feature different spectra.
