Definitions
- the invention relates to an anti-copying film or layer, consisting of a film or a layer of transparent material with a plurality of spaced-apart, at least partially non-transparent areas, the planes of which are in approximately the same predetermined position with respect to the upper ⁇ surfaces of the film or layer are arranged so that it is essentially transparent from a predetermined angle of view of the surfaces of the anti-copy film.
- Such a film which is intended to enable copy-proof documents, is effective in covering up graphic information and / or characters of a document or generally a document, in a vertical line of sight, as is present in a copying machine, and the graphic information and / or characters below to make a predetermined other point of view, based on the level of the document, visible.
- such an anti-copying film is a transparent plastic film with opaque parts located therein or with any notched or sawtooth-shaped surface in cross-section, in which a first oblique or vertical surface is either black or reflective with respect to a vertical viewing angle , related to the level of the film or the document, and the other oblique surface is transparent from a different angle, so that the information or characters are legible.
- a first oblique or vertical surface is either black or reflective with respect to a vertical viewing angle , related to the level of the film or the document, and the other oblique surface is transparent from a different angle, so that the information or characters are legible.
- Such notched or sawtooth-shaped surfaces are very difficult to produce, since the surfaces first have to be embossed or hammered in, and then the inclined surfaces have to be provided with a black or reflective material, the accuracy of these operations having to be so great that the Transparent surfaces are not affected, that is to say also partially provided with black and reflective material.
- black ink is provided in a cross-section of a sawtooth-shaped film in the valley between two successive teeth, which at least partially covers part of the substrate.
- Practical manufacturing designs are not described here either.
- An anti-copy Mectium for writing or printing is known from AU-A-610 614, in which the medium contains a photosensitive color system which, when irradiated in a photocopier, makes the scnft unreadable or makes the copy distinguishable from the original , so that either the original is clearly worthless as copied.
- Anti-copy film or layer for documents consisting of a film or a layer of transparent material with a plurality of spaced apart, at least partially non-transparent areas, the planes of which are approximately the same predetermined position relative to the surfaces of the film or Layer are arranged so that from a predetermined angle of view of the surface of the film or the layer of the anti-copying film is essentially transparent, since it is resolved that the regions consist at least partially of a material which is photochemically non-transparent or reflective material is converted.
- a second practical solution to the problem is an anti-copying film or layer consisting of a film or a layer of transparent material with a plurality of spaced apart, at least partially non-transparent areas, the planes of which are approximately the same are positioned opposite the surfaces of the film or layer so that from a predetermined point of view of the surface or layer the anti-copy film is substantially transparent, so that the areas are made of coextruded transparent and not transparent transparent plastic material are produced.
- an anti-copying film or slide consisting of a film or a layer of transparent material with a plurality of spaced-apart, at least partially not transparent areas, the planes of which are arranged in approximately the same predetermined position with respect to the surfaces of the film or layer, so that from a predetermined angle of vision on the surfaces of the anti-copying film it is essentially transparent, that the areas consist of non-transparent or reflective strip material, which are inserted into the same after the extrusion of the transparent material with grooves or grooves.
- the non-transparent areas are inclined layers, which consist of exposed and developed photosensitive material.
- the transparent material consists, for example, of a thick photo emulsion that is partially exposed and then developed.
- the inclined layers are essentially formed through the thickness of the film or layer.
- the transparent material can also consist of a plastic which contains at least one photosensitive material, and the exposure can take place locally and in an inclined plane relative to the material surface.
- the film or the layer can be provided on at least one surface with a plurality of approximately parallel and approximately equally spaced grooves or grooves into which the at least one photosensitive substance is introduced.
- the grooves or grooves can be arranged perpendicularly or obliquely to the film or layer surface.
- non-transparent or reflecting areas as first opaque or reflecting layers on the top of the film or layer and as second opaque layers on the underside which are horizontally offset from the first opaque layers of the film or the layer are formed on the underside of the film or the layer. Exemplary embodiments of the invention are described below on the basis of schematic drawings.
- Figure 1A is an anti-copy film with opaque sloping layers
- 1B shows an anti-copy film with a sawtooth cross section on the surface
- Figure 2A shows an anti-copy film with rectangular shape grooves and unexposed photosensitive material therein
- FIG. 2B shows an anti-copy film with diamond-shaped grooves according to FIG. 2A
- FIG. 3A shows the rectangular shape grooves from FIG. 2A with exposed, opaque photosensitive material
- FIG. 4A shows a double-sided groove design according to FIG. 3A
- 4B shows a double-sided groove design according to FIG. 3B
- photochemically convertible material is any photosensitive material that changes in its physical properties due to the action of radiation (photons, corpuscles), here changes from a transparent to an opaque state.
- FIG. 1A shows an anti-copying film F or an anti-copying layer consisting of transparent to transparent plastic material, in which a number of parallel inclined layers SS are provided at equal distances from one another, the layers SS being separated by the Total thickness d of the anti-copying film F are continuously formed.
- the plastic material preferably contains photosensitive substances which are reactive to light of a special wavelength and which make the affected areas opaque or opaque.
- the effect of light can be limited locally to the predetermined areas of the inclined layers via masks, or rows of light (arrays) or a surface (matrix) can ensure the limited incidence of light.
- arrays can be any type of light.
- the radiation should be incident obliquely in order to be able to form the oblique layers SS at a predetermined angle ⁇ , between ⁇ approximately 30 ° to ⁇ approximately 73 °, in particular at ⁇ approximately 45 ° to ⁇ approximately 60 c .
- the information I of the document D is visible through the transparent layers TS at the angle ⁇ or in the direction of the viewing arrows VI. According to arrows VV, however, information I is hidden and invisible.
- the opacity of the layers SS should therefore be chosen so that the information is at least indistinctly recordable for standard copying machines and is unreadable for humans.
- FIG. 1B shows an anti-copying film F1 or an anti-copying layer with a sawtooth-shaped surface OS in cross section.
- the one flanks of the sawtooth shape are e.g. arranged at an angle ⁇ and the others placed approximately perpendicular.
- the triangular shape grooves E are in turn filled with photosensitive material-containing plastic PH, whereby, as described above, locally limited light, e.g. every second groove E2 becomes opaque (PHE) and every first groove El remains partially transparent.
- the inclined surfaces Q can be designed optically such that total reflection occurs with vertical radiation, or they can be formed with a reflective layer QS. This also results in an oblique viewing direction corresponding to the direction VI and an approximately vertical covering direction W (FIG. 1).
- the film or layer material F1 should be transparent to transparent plastic material which is either designed as a self-supporting film or layer (F1) or is provided with a carrier film or layer G.
- the grooves of the surface OS can be embossed or during manufacture, e.g. by extrusion or mechanically attached, e.g. by cutting.
- FIG. 2A shows a further anti-copy film F3 or layer version with longitudinal grooves NU which are approximately rectangular in cross section and which are in turn filled with photosensitive material PH, as described above for FIG. 1B.
- the plastic of the base material is again transparent to transparent and the grooves NU are made according to the methods described.
- the PH material is exposed by opaque exposure (arrows LU) and opaque (PHE), as shown by hatching in FIG. 3A.
- W only part information PI can be copied in the copier, while the supplementary information PP is only visible at an angle (here about 63 °).
- FIG. 2B Another more favorable embodiment of an anti-copy film F3 or layer is shown in FIG. 2B.
- the diamond-shaped grooves RU here are either as grooves NU
- the finished anti-copying film F3 or layer with opaque inclined layers SS in the angular range ⁇ is obtained with FIG. 3A.
- the grooves NU and RU are formed approximately up to half the thickness d of the film F2 and F3. They can also be deeper. Corresponding to the total thickness d, the depth T of the grooves NU and RU can only be formed if a carrier film or layer G, not shown here, is used, to which the layer F2 or F3 is attached or applied.
- FIG. 4A shows a rectangular groove film F4 or layer in comparison to F2 on both sides and provided with rectangular grooves NU.
- the grooves NU1 on the top and NU2 on the bottom are arranged offset from one another.
- the opaque groove content is produced as described above by means of a photochemical material PH and its full-area exposure (PHE).
- Partial information is visible in directions VI and VII, the completeness of the visible information increasing with a decrease in the depth T of the grooves NU1 and NU2 regardless of the width bb of the individual grooves NU1 and NU2.
- FIG. 4B shows a film or layer design F5 corresponding to FIG. 4A, which, in contrast to F3, is formed on both sides with inclined layers SSI and SS2, which can be produced as described above.
- the sloping layers SSI and SS2 are horizontally offset from one another.
- the information I is hidden in the vertical viewing direction W and at least partially visible in the oblique direction VI
- FIGS. 1B, 2A and B, 3A and B and 4A and B can also be realized with opaque or reflective, strip-shaped inserts K without photosensitive groove or groove fillings.
- the latter can e.g. be inserted into the grooves or grooves immediately after the extrusion of the groove or groove shape material.
- Anti-copying film or layer consisting of a film or a layer of transparent material with a plurality of spaced-apart, at least partially non-transparent areas, the planes of which are roughly in the same predetermined position with respect to the surfaces of the film or Layer are arranged so that it is essentially transparent from a predetermined viewing angle on the surfaces of the anti-copying film.
- the areas consist at least partially of a photosensitive material which is converted into non-transparent or reflective material by the action of radiation, wherein grooves or grooves in which the photosensitive material is located can also be provided in the transparent plastic material.
