Description

The solution relates to the production of stickers with pseudo-volume (3D, stereoscopic) images.

A sticker is a type of paper or plastic that is sticky on one side and usually with a design on the other, and is used for decoration and / or information depending on the situation. Stickers come in a wide variety of shapes, sizes, and colors and are glued to objects such as boxes, packaging, paper, furniture, walls, and so on. Stickers on flat transparent surfaces (mainly glass), such as car windows, shop windows, office and other partitions, glass doors, stand somewhat separately.

The imagery of the design of the stickers is enhanced when creating pseudo-volumetric images. This can be achieved, for example, using computer prepress (E.A. Wazenmiller, http://www.3dmix.com/eng/articles/pseudo/), cutting out any objects from flat originals and arranging them in layers, shifting relative to each other. There is no complete illusion of volume: the cut objects still look flat, but they appear to be located at different distances from the observer (some closer, others farther). A greater pseudo-volume perception effect is observed when the foreground image shifts relative to the background image when the observation point changes. This can be achieved by printing on lenticular lenses with special preparation of the printed file (patent US 6751024 B1). True, this effect is noticeable when the movement of the observation point is perpendicular to the direction of a parallel row of lenses. In addition, there is no illusion of the distance between foreground and background images.

A method of obtaining an “integrated image” is known from the prior art — it is a true method of “auto stereo image” that is visible without the need for special glasses (Yutaka Igarashi, Hiroshi Murata, Mitsuhiro Ueda (1978) 3-D Display System Using a Computer Generated Integral Photograph. Japanese Journal of Applied Physics, vol. 17, number 9, p. 1683). The integrated image consists of a huge number of micro-images (patterns) that the observer looks through through an array of spherical convex “lens-lenses”, one “lens” for each

microimages. Moreover, spherical lenses are on one side of a flat transparent material, and micro images are on the opposite. Strict requirements for spherical lenses: their centers must be strictly located at the same distance from each other (at the corners of a regular triangle or square) and have the same focal length equal to the thickness of the transparent flat material on the surface of which they are formed. Thus, a layer of special hexagonal spherical lenses (MicroLux ™ fly's-eye lens) is formed on the surface of a thin (380 μm) sheet of polyester or polypropylene (https://dplenticular.com/products/microlux/). Spherical lenses can also be printed. For example, Agfa Graphics developed UV printers such as the Jeti Mira and software for printing both lenticular and spherical lenses (https://www.agfagraphics.com/global/en/articles/news/20161206-jeti- mira-led.html). The patent number RU 2526682 describes a method for forming a lens layer by screen printing.

In all of these options, the formed lenses are integral with a flat transparent material, on the back of which certain printing procedures are carried out (usually printing a pattern and a white layer) to form a three-dimensional image. The focal length of the lenses during their formation is chosen equal to the thickness of a flat transparent material. The volume of the image formed in this way, unlike the lenticular one, is observed inside the solid angle of at least 90 degrees perpendicular to the plane of the lens layer, remaining clear and readable. And, which is very important, it is clearly distinguishable to people with monocular vision. The virtual depth of a pseudo-volume image depends on several factors and can be an order of magnitude greater than the real thickness of a flat transparent material.

Traditional labels, due to their consumer properties, usually have a thickness of a fraction of a millimeter. If you make a sticker with a pseudo-volumetric image on a material of similar thickness, a well-readable virtual image depth will be observed no more than 10 mm, and when you try to enlarge it, the objects will “blur” (the image will become blurry). This is clearly visible when the observer is in the immediate vicinity of it, or at a distance of up to 1-2 meters. The described principles for creating a pseudo-volumetric image allow the manufacture of products with a virtual depth of several (up to 10 or more) centimeters. And it will be distinguishable already at distances of 2-5 or more meters, but this requires the use of transparent material of several millimeters, which limits their use in this quality.

The objective of this utility model is to develop a sticker with increased information content of a printed image - an increased value of the virtual depth of a pseudo-volume image for use on flat transparent surfaces.

The technical result consists in the fact that the sticker is a complementary pair of layers of thin transparent self-adhesive material with a printed image, and the layer applied to the front surface of the transparent material consists of many lenses applied in a specific order to the material in a printed manner with a programmable focal length of each lenses, and the layer applied on the back side consists of printed objects of any shape, and applied in such a way that when combined with the front side layer, a previously predicted moire effect appears, the pattern of which will determine the virtual depth of the pseudo-volume image.

The technical result is provided by the design and technological features of the implementation of the sticker options described below, and methods for their manufacture.

The solution to this problem is based on the initial requirement to create stickers with increased information content for flat transparent surfaces. These are display windows, transparent partitions in rooms, transparent doors of rooms and doors in commercial refrigerators, car windows and others. Usually these are transparent surfaces with thicknesses of 3 to 8 mm. Such surfaces, if they are separated from the application (or are at the stage of blanks), taking into account their known thickness, can be used as a flat transparent material and it is possible to print lenses on one side and print on the opposite side. Here, indeed, it is possible to obtain images with a pseudo-volume depth of several centimeters, but such a structure is cumbersome and has limited capabilities.

A specific solution to the problem lies in creating a design where the lens layer and the image layer are formed independently of a planar transparent material, creating a complementary pair, and can be integrated into a single unit directly at the place of application. For this, the lens layer and the image layer are formed in any known manner on a thin transparent self-adhesive material, and the specific thickness of the transparent surfaces of those objects where such a sticker should be placed is laid in the calculation of printing parameters. The lens layer is glued to the front surface of the object, and the printed image layer, made mirror-like, is glued to the opposite side.

The effect of pseudo-volume is formed in the volume of transparent material directly below the image on the front surface, configured by the geometry of the printing lenses and the limited back with a printed pattern.

Thus, one of the tasks of this utility model was solved: a sticker was developed with increased information content of the printed image — an increased value of the virtual depth of the pseudo-volume image for use on flat transparent surfaces.
