Definitions

• Technological design described below involves an optical three-dimensional effect resulting from decorating flat transparent materials subject to special treatment such as foils and organic or inorganic glass that may find application in advertising and publicity, packaging, bookprinting and other areas of polygraphic industry.
• the three-Dimensional decor for flat transparent materials pursuant to this Utility Model allows for creating a broad range of three-dimensional patterns apparently located both in front and behind the relevant surface plane.
• transparent materials include foils and sheets of organic or inorganic glass.
• the face of such transparent materials is provided with cylindrical lenses whose focus points lie in the plane of the reverse side of the materila applied.
• the reverse side is provided with a screen the individual elements of which are based on the patterns to be obtained, yet transformed in a certain manner:
• Reverse side screens may be combined with normal planography print to stress, in a more expressive manner, the three-dimensional effect of the decor. This combination may be achieved in several ways.
• First, the assembly of planography print and reverse side screen may be achieved using the usual procedure of painting out in the manufacture of original.
• Another possibility consists in first printing the planography print and, subsequently, the reverse side screen on the reverse side so that, viewed from the front side, the three-dimensional decor will appear only on places free of the planography print.
• Yet another possibility consists in the completion of planography print on the front side of the material by means of stickers or direct printing which requires, due to a certain unevenness of the surface material used for lenticular screens, the selection of an appropriate printing technique such as silk-screen printing or tampon printing.
• Fig. 1 shows a three-dimensional pattern in the form of a square standing on its edge. It is our intention to create a three-dimensional decor involving a network of such squares appearing as if situated behind the foil's plane.
• Fig. 2 shows one of the elements comprising the chosen decor drawn following to transformation completed in accordance with the principles as desribed above. It is evident from the figure that any height dimensions have been preserved while the width has been reduced to approximately 95 % of the spacing between the individual elements of the optical screen.
• Fig. 3 shows a schematic view of a portion of the transparent material including the back-face screen 2 and the resulting pattern 3 creating the three-dimensional decor.
• Three-dimesional decor for flat transparent materials may be used for consumer goods packaging, materials intended for use in design of industrial products, book envelopes, CD, LP, video-cassettes, in polygraphic industry, publicity, architecture and in applied art.
