  • the utility model relates to printing products, such as secure plastic bank and credit personal cards, but can equally apply to discount cards, passes, greeting cards, book covers, etc.
  • a common feature of printing products, to which the claimed utility model relates, is that in their design, in addition to attributes that are integral to each particular product, elements that reproduce optical effects, namely stereo and / or vario images, are introduced.
  • one of the common design techniques for obtaining printing products with a stereo / vario effect is the use of imaging systems based on lenticular lenses or lens structures.
  • parallel convex lenses are formed on one side of the transparent plastic substrate, and images are printed on the other side, and to obtain a qualitative effect, the focus of the lenses F must necessarily be on the image (see Fig. 1).
  • Printing products may contain areas where drop-shaped lenses are selectively formed on top of the graphic image, creating the illusion of depth at this point.
  • increased demands are placed on the quality of reproduction of logos and texts depicted on the front side.

  • the disadvantage of this solution is that the image is printed on the back of the sheet of material with lenticular lenses, whose focus is on the back of the sheet of material, and therefore small details of images with clear contours (logos, etc.) acquire geometric distortions type of "saw".

  • the insert 6 has a thickness at which the foci of the lenticular lenses F of the layer 4 placed on the front side of the sheet 3 are located strictly on the stereo / vario image 8. This allows you to get the highest quality stereo / vario effect.
  • the second zone - images that should not be affected by the stereo / vario effect, and which should be reproduced with maximum quality - for example, logos, company names, etc. They are applied on the top (front) side of the insert and in the multi-layer pie of a plastic card are in close proximity to the lenticular lenses of the upper layer (80-150 microns.), outside the focus area of these lenses. As a result, when viewing these images through the lenses, they are reproduced with maximum quality, without distortion like a “saw”, since the lenses do not work in the out-of-focus area, since the top layer 4 behaves like a simple transparent material.
  • the claimed plastic card has two zones over which the images are spaced.
  • a stereo / vario image is placed, which provides a high-quality stereo / vario effect when viewing.
  • the second zone in which a simple image is placed, is free of stereo / vario effect, the images placed in it are reproduced with maximum quality.
  • the presence during visual viewing of such images, perceived simultaneously at different levels, allows visual verification of the authenticity of the card.
  • the insert 6 with its reverse side by means of the adhesive layer 9 is bonded to the lower layer 10 made of transparent or opaque plastic (polyvinyl chloride, polyester, polyethylene terephthalate, acrynitrile-butadiene-styrene, polycarbonate, etc.).
  • This layer typically has a thickness of 100 to 500 microns.

  • the lens relief is partially removed from it on predetermined coverage areas.
  • the material with lenticular lenses in the form of a roll, from which layer 4 is made is passed through a die-cutting rotary machine before cutting into sheets, in which the upper embossed layer is notched to remove notched sections.
  • a thin lenticular coating acquires smooth areas free of lenses, which can be used to apply holograms and emboss personal data.

  • the card is assembled using the high-temperature lamination method and is a standard procedure commonly used in the production of bank cards.
  • the product which is described as an example as a personal bank card
  • the latter carries out all the financial transactions established for it.
  • the use of heat-resistant material as layer 4 eliminates the melting of the lenses during lamination (using standard plastic, lamination leads to a loss of relief at the lenses, which makes viewing stereo / vario images impossible).
