Description

Method for producing optical lenses, in particular for viewing a lenticular image, method for producing a

Lenticular image, method for making Braille and products produced by these methods; Printing machine for the production of lenticular images, optical lenses or Braille characters

The invention relates to a method for producing optical lenses according to the preamble of patent claim 1, in particular for viewing a lenticular image, a method for producing a lenticular image according to the preamble of patent claim 3, a method for producing braille according to claim 11, produced by these methods Lenticular images, the use of one of the methods for producing certain products and a printing press for applying one of these methods or for producing one of these products according to claim 19.

The existing lenticular method is based on the effect that a substrate printed with a plurality of images, connected to a plurality of specially arranged convex objective lenses above, gives the viewer the illusion of a three-dimensional (3-D) image, or a multi-image, generate moving image depending on the viewing angle. The lens layer is thereby produced as a special film and bonded by gluing or laminating with the image plane printed on the substrate, or the lens layer film is used as a substrate for the back-printing. The specially made lens film and the required Process steps of exact positioning on the image plane and bonding to the substrate or positioning for the production of the image plane on the back of the film make this imaging technique so far relatively expensive and have thus limited their spread.

A method in which the lens layer is formed on one side of the substrate by embossing the lens bodies in a transparent layer applied by laminating a transparent film or by screen printing is known from US20020135873A1. In this case as well, after the printing of the image or the images and the application of the transparent layer, the further process step of embossing the lenses is necessary.

US Pat. No. 6,833,960 B1 discloses a lenticular image system in which a multiplicity of spaced-apart convex lens bodies are arranged in different orientations to the image-forming objects on the substrate in order to produce new image effects, such as different color intensities in different image areas. In addition to the production of the lenses by casting, extrusion or embossing, the possibility is also mentioned of applying the lenses to the image side or the back side of the substrate by printing. However, the person skilled in the art will not receive any indication as to how the lenses can be produced by printing.

From DE 100 57 526 A1 a method for the production of microlenses by means of a piezo-dosing device is known in which an organically modified silane is deposited in droplet form on a primer pretreated surface of a substrate and cured there.

The object of the invention is to provide a method by means of which optical lenses can be produced in a simpler and more cost-effective manner, as well as further advantageous methods, products and printing machines that use this method. This object is achieved by a method for producing optical lenses having the features of claim 1, a method for producing a lenticular image according to claim 3, a lenticular image according to one of claims 7 to 10, a method for producing braille according to claim 11, a text - and / or image information containing document according to claim 14, several advantageous uses according to claims 17 and 18 and a printing machine according to claim 19 solved. Advantageous embodiments of the invention are specified in the respective dependent claims.

According to the invention, creation of the lenses is possible by a material-applying method, such as various printing or injection or casting methods. One or more lens base layers, which are arranged with a smooth surface under the actual lens bodies, can also be produced by lamination of a film, which is also to be regarded as material-applying process. The application of the lens material takes place in one or more layers, preferably followed by the application of the individual layers each immediately followed by a curing step, which preferably takes place by influencing the material with energy, such as UV light, microwaves or laser. The lenses are formed from a plurality of superposed material layers or material regions, which are preferably produced by printing a plurality of transparent layers, either in one pass through a plurality of printing units arranged one behind the other or through several passes on the same printing units. If for a lenticular image first the

Image layer (s) and then the lenses are applied to the substrate, which can be done in the same or another material applying method, the object lenses or lens layers produced directly above the image layer on the substrate can be made variable and so by the individual nature and arrangement of the printed, stamped, molded, cast or embossed lens body different, sometimes completely new effects are generated. By means of the method according to the invention with a direct application of raised areas, further advantageous application possibilities can also be realized. Braille characters which can not be attached to a substrate as before in embossed or stamped form, but are applied directly to the substrate by means of this method in the form of a layer elevation, can be generated by the layer elevation necessary for this purpose. In a particular embodiment, the transparent raised dots of braille can even be applied directly to the corresponding fonts and / or image passages, so that documents generated by such a method can be used by both sighted and blind users. For the generation of Braille characters usually a single lens layer is sufficient.

The production of the lens surfaces or of the raised lens layers is particularly preferred by a printing process, which then generates the lens layers or, for example, Braille characters in one operation or in the same printing machine immediately after the image plane has been generated. Thus, special order cylinder for generating certain lens structures or other raised structures are integrated into the printing press, so that the substrate (sheet or printing web) immediately after generation of the image plane with the overlying single or multi-layer lenticular or other raised preferably transparent areas is still provided in the same printing press. Alternatively, the printing press is provided with a lamination, which is arranged after the printing units for the production of the image plane and before the application cylinders for applying the lens structure and laminated as a transparent intermediate layer, a film on the image plane, on the one hand protects the image plane and sealed and another forms with its height a lens base layer. The lens base layer produced by a film can be made thicker than is possible with a single layer application by a printing unit. In a correspondingly thick lens base layer is sufficient to produce the desired Focal already a single lens layer to produce the actual concave or convex curved lens body.

In principle, all printing processes, such as flexographic printing, offset printing, screen printing, gravure and gravure printing, laser printing processes (such as, for example, the LaserSonic® process, registered trademark of Aurentum Innovationstechnologien GmbH, D-55129 Mainz), thermal sublimation printing, inkjet printing are used as the printing process , thermoplastic printing, electroplating, or other application methods suitable for applying the lens layers. As already mentioned, the lamination of a lens base layer is also to be understood as a material-applying method.

Because of the simpler structure of the machine, the same method as that for forming the image plane can be used for the application of the lens layers. However, it is also possible to print for different

To arrange printing process in a printing machine in a row, or to produce the image layer and the lens layers in different printing machines or applicators. By directly applying the lens layer or the lens layers to the substrate lens body or raised layers with different shape and

Dimension can be generated, whereby a very individual image design - if desired, even in different areas of the image plane - is possible, which was not possible in the previous use of the entire image plane through uniform lens sheets. The method according to the invention thus not only enables a considerably accelerated and more cost-effective production of lenticular images, for example as 3D images on high-quality packaging or braille characters, but also creates considerably greater design freedom.

Suitable materials for the lens layer (s) or raised layer (s) are, in particular, thermoplastics, in particular polymers, intumescent paints and lacquers, resins, wax or even glass, provided that they are at least partially transparent. The lens layer or Individual lens layers can also be selectively colored to achieve special effects, but always a partial transparency is guaranteed. In the swelling colors or paints an increase in volume is achieved by an energy input, which, for example, lens body can be increased from initially low height to a multiple of this height.

Particularly noteworthy is the creation of Braille characters on substrates in the listed method that when using clear print materials for the raised areas braille can be printed directly on the human-readable textual and / or visual information without losing the readability of this text or image to influence. However, it is also possible to generate braille characters by applying raised transparent or non-transparent areas below or above, or next to, the visible text and / or image information by material-applying methods.

As the substrate, all materials printable by the above-mentioned printing methods in sheet form, sheet form or sheet form such as paper, paperboard, plastics, metals, textiles or the like are suitable. The applications are extremely diverse. An outstanding one

Possibility is the design of advertising leaflets and packaging, which receive a high degree of attention through lenticular images at low prices.

By means of the method according to the invention, however, not only

Lenticular lens layers are produced - even if this is a preferred application. A variety of types of optical lenses can be produced on a wide variety of substrates, for example disposable spectacles or sunglasses, or contact lenses, which are removably printed on a substrate and can be removed as needed for use by the substrate, or a lens layer on an image chip of a digital camera or video camera for producing different focal lengths, for example to compensate for the edge distortions or for the different colors, or diopter films.

In Fig. 1, there is shown a lenticular image on a substrate 1 in a conventional, known printing process, such as flexographic printing, offset printing, screen printing, gravure and gravure printing, laser printing processes (such as LaserSonic®, registered trademark of Aurentum Innovation Technologies GmbH, 55123 Mainz), thermal sublimation printing or inkjet printing, an image plane 2 composed of a plurality of image strips 3, 4, 5, 6 is produced. The image strips 3, 4, 5, 6 together form two or more sub-images, which generate a three-dimensional image or a moving image comprising a plurality of images through the subsequently applied lens bodies 8 of a single-layer or multilayer lens layer 7 at different viewing angles of the observer.

The lens layer 7 with the lens bodies 8 is applied according to the invention directly by a material-applying method, for example by a printing process on the image plane 2. In this case, the same printing method that was used to produce the image plane 2 can be used as the material-applying method for producing the lens layer (s) 7. However, it is also possible to use a different printing method than the printing method used to produce the image plane 2 to produce the lens layer (s) 7.

As an alternative to application by a printing method, it is also possible to apply the lens layer (s) 7 by means of a casting method or a spraying method or a galvanic method. It is essential for the invention that the lens layer (s) 7 is produced directly on the substrate 1 or the image plane 2 already present thereon by a material-applying method, so that the separate manufacture and subsequent application of a lens film is avoided.

The applied (n) lens layer (s) 7 consists of a colorless or slightly colored, clear or at least partially transparent substance of a respective application method and the respective substrate 1 and the image plane 2 compatible material. In question come especially thermoplastics, swelling paints and varnishes, resins, wax, polymer-containing substances or glass.

The lens body 8 of the lens layer 7 can be printed by surface or selective application of more or less lens material in different shapes and sizes in one or more passes on the image plane 2.

In the embodiment according to FIG. 1, the lens bodies 8 correspond to a conventional lenticular arrangement with a plano-convex lens shape. This can be used to create three-dimensional image representations but also alternating images with resulting morph and move effects.

In the embodiment shown in FIG. 2, a second lens arrangement with plano-convex lens bodies 9 is printed on the substrate 1 provided with the image plane 2 in addition to a first lens arrangement with plano-convex lens bodies 8 in their interspaces. The effect achievable with this increases the three-dimensional image representation many times over. In a change of image representation, the individual motif objects are no longer clearly separated from each other, but deliberately blur at the edges into each other.

In the embodiment shown in Figure 3, a lens array is printed by printing on the substrate 1 and the image plane 2 printed thereon, in which a lens layer 7 with plano-convex lens bodies 8 has a bottom lens layer formed in one or more material application passes or by a laminated film 10, by which the distance of the lens body 8 is enlarged to the image plane 2. By increasing the lens base, the viewing distance of the viewer can be changed. A typical layer thickness of a lens base layer 10 for a normal viewing distance of a lenticular image or document is, for example, about 0.4 mm. This can be done in one pass using a fast curing lens material with an immediately following Curing by UV light, by microwaves or treatment with a laser are applied or through multiple passes in a printing unit or by multiple printing units, the layer thickness of the individual layers depending on the printing process and consistency of the selected lens material in the range of one to several microns lies. When using a film laminated to the image plane 2 as the lens base layer 10, it is generally sufficient to use a single layer because of the freely selectable film thickness. With a sufficiently high lens base layer 10, in some cases a single lens layer 7 is sufficient to produce the desired lens body.

In FIG. 4, a lens layer 7, which is composed of a plurality of successively applied lens layers 11, 12 and 13, is applied to the image plane 2 applied to the substrate 1. The plurality of lens layers 11, 12 and 13 can be applied successively by the same printing device in several passes. However, several similar or different printing devices can be provided in succession, by means of which the different lens layers 11, 12 and 13 are applied in one pass or several passes. Preferably, each application of a lens layer 11, 12, 13 is immediately followed by curing of the respectively applied layer. If the individual applicators have sufficient distance, the lens layers can also harden independently or with low energy exposure before the next layer application takes place. In the example according to FIG. 4, the lens body 8 produced overall by the plurality of lens layers 11, 12 and 13 forms a lens mold based on a Fresnel lens, the outstanding feature of which is extremely straightforward image reproduction. In contrast to the traditional plano-convex lens shape, the effect achievable with this is an abrupt change of the individual image motifs in a change-over image representation (hard changes instead of soft transitions). The total height of a lens layer 7 consisting of one or more layers is for example about 90 μm. The embodiment according to FIG. 5 shows a lens layer 7 which is printed on a substrate 1 and an image plane 2 printed thereon and which here is composed alternately of plano-convex lens bodies 14 and plano-concave lens bodies 15. Depending on the viewing distance, this makes it possible to achieve different partial influences on the switching effects in the case of a change picture.

In the embodiment shown in FIG. 6, the lens layer 7 has lens bodies 16 and 17, respectively, with different lens shapes with different focal lengths, which in the exemplary embodiment are all designed as plano-convex lens bodies, but can also be designed as other lens shapes. As a result, various effects such as three-dimensional image display, tilt, morph and move effects can be combined in a single image.

FIG. 7 shows an image layer 2 containing text information which is applied to a substrate 1 and to which a layer of spaced braille characters 18 corresponding to a lens layer 7 from the preceding exemplary embodiments has been applied to a method applying material directly. As a result, it is ideally possible to generate documents in a single pass through a printing press that contain information for sighted people as well as information that is transparent, sublime, and therefore palpable information for blind people, both directly and indirectly to the text and / or image information. In an arrangement next to (above or below) the text and / or image information of the image layer 2, a non-transparent embodiment of the Braille character 18 is also possible.

As a result of the more direct printing of a substrate 1 according to the invention with an image plane 2 and the subsequent more direct printing of the image plane 2 with at least one lens layer 7, documents containing lenticular images or braille characters 18 can be manufactured considerably more cost-effectively than hitherto, thus creating broad new application possibilities, for example in advertising and the packaging industry. As the various embodiments according to FIGS. 2 to 6, the direct application of the lens layer 7 according to the method of the invention has also substantially increased the freedom of design for such images since, unlike a laminated lens film, not only one type of lens but quite different lens shapes and sizes are used for the different image areas are usable.

The material for producing the lenses or the lens layer (s) is applied by a plurality of successively applied material layers or material subregions. For the hardening of the material layers, there are basically two alternatives: on the one hand the hardening of each individual applied layer immediately after the application, or the joint hardening of all material layers after the application.

As a hardening method, it is particularly suitable to apply the applied to the substrate 1 lens layers 7 and lens body 8 by an application of energy, such as a treatment with a UV light, with microwaves or irradiation with a laser. As a result, both enlargement by expansion of the lens material (in particular when using source paints or lacquers) and solidification of the lens body 8 or lens layers 7 can be achieved, for example by crosslinking or targeted alignment of particles contained in the lens material.

Suitable materials for the lens layers, for example, UV coatings, as they are known in flexographic or screen printing, or by energy input in their orientation modifiable photopolymers (for example, the company BASF) are considered. However, in a special case, lenses can even be made from water if they are suddenly frozen by energy removal and the lenses thus produced are constantly used in a temperature range below 0 ^° C. during their use. In FIG. 8, stripe-shaped image regions 210, 211, 212, 213, 214 of a first motif region and strip-shaped image regions 220, 221, 222, 223 of a second motif region, for example an alternating image of a lenticular assembly, are alternately shown in plan view. These strip-shaped image areas form the image plane 2, which are applied to the substrate 1 in a first method step, for example by printing. 9, in a next method step, a lens base layer 10 is applied to this image plane 2 by a method applying a material, preferably by printing. According to FIG. 10, at least one lens layer 11 is applied to the lens base layer 10 in a next method step, and optionally a further lens layer 12 is applied in a further method step. The application of the lens base layer 10 can also be carried out by successively applying a plurality of layers - see the lens base layers 10 or 11 in FIG. 14 - to a desired thickness. Due to a different thickness of the lens base layer 10, the lenticular image can be adapted to a different viewing distance. The size, the distance and the curvature of the lenses in the lens layers 11 and 12 is decisive for the desired resolution or the desired effects when viewing the lenticular image.

As the first lens base layer 10 above the image plane 2, as shown in FIG. 21, a transparent lacquer layer 101 or laminated film layer is preferably used, by means of which several advantages can be achieved. On the one hand, differences in height, as may arise in transition areas of different color areas 201, 202, 203, 204, 205 due to their different layer thicknesses, are completely leveled out by the film or lacquer layer 101, so that for the lenses 7, 8 arranged further up , 9 a uniform distance from the image plane 2 is generated. The film or lacquer layer 101 further protects the color layers of the image plane 2. Furthermore, it is achieved by the film or lacquer layer 101 that, in the case of a very rough, coarsely porous or absorbent substrate 1, the material of the lens layers 10, 11, 12 or 71 - 77 does not pass through the color layers of the Image plane 2 are sucked into the substrate 1. Finally, the film or lacquer layer 101 advantageously already forms at least part of a lens base layer 10, which in many cases is required in any case for the desired optical purpose.

Depending on what height of a single lens is needed for the desired effect, it may be sufficient to apply a single lens layer. For larger focal lengths in each case several lens layers are useful. Thus, the convex lens body 8 shown in FIG. 11 is approximately modeled in its contour by the plurality of lens layers 71 to 77 shown in FIG. 12. Alternatively to an application of lens layers, the same lens body 8 according to FIG. 13 can also be formed by a plurality of layers 71 to 75 of individual lens layer particles 19. These are shown schematically cubic in Figure 13, but they may have any geometric shape.

As shown in FIG. 15, the structure of a lens body 8 can also be formed by a plurality of lens-shaped lens layers 71 to 74. In the Fign. 15 and 16 - as generally in all sectional views - the dividing lines between the individual layers 71 to 74 are shown in order to illustrate the layer structure. In contrast, in the actual embodiment, the separation between the individual layers is not recognizable, but the lens body 8 acts visually like a single homogeneous body.

FIG. 17 shows a concave lens body 8 made up of a plurality of lens layers 71 to 74. The concave structure is produced, for example, by a nozzle-shaped application device 26 whose distance from the substrate is also variable, as is its lateral movement and its rotation with respect to a plane parallel to the substrate 1. It is therefore given a mobility with at least three degrees of freedom for the applicator 26. FIG. 18 illustrates the possibility of producing a lens body 8 from a plurality of lens layers 71 arranged one above the other by a spiral guide of such an application device 26.

In FIG. 19, similar to FIG. 13, the structure of a lens with a plurality is shown

Lens layers 71 to 74, consisting of individual lens layer particles 19 illustrates, wherein in contrast to Figure 13, the lens body 8 produced has a concave shape.

The method can be realized with conventional printing machines, wherein in the simplest case, a part of the device, which is intended to apply a color, is used for the application of the transparent lens material or the raised areas. However, it is also possible to integrate special printing units into the printing press which, in the same or a different printing method, produce the lens layers or the raised areas following the printing of the substrate 1 with the image plane 2.

FIG. 20 schematically shows, by way of example, a printing machine 20 suitable for producing optical lenses on a substrate 1. Thus, for example, during the passage of the web-shaped substrate 1 through the successively arranged printing units 21, 22, 23 and 24 successively the first strip-shaped interrupted image motif of the image plane 2 in the first printing unit 21, the strip-shaped, staggered second image motif of the image plane 2 in the second printing unit 22nd , the lens base layer 10 in the third printing unit 23 and the example convex lens body 8 in the fourth printing unit 24 are generated. In this case, for example, the first printing unit 21 and the second printing unit 22 generate the image plane 2 in offset printing and the third printing unit 23 in the flexographic printing process, the lens base layer 10 apply. In fourth printing unit 24, for example, the manner of a

Ink jet printing printer is configured with a plurality of nozzles, then the one or more lens layers for the convex lens body 8 is applied and if necessary in the immediately downstream Hardening station 25, cured by UV light or by irradiation with a laser. Optionally, instead of or additionally to the printing unit 23, the printing machine has a spraying device for applying a transparent lacquer layer 101 or a laminating device for laminating a foil layer 101 as at least part of the lens base layer 10. The above assignment of the different order process steps to the respective printing units is only an example; Any material-applying method may be used in any desired combination of suitable application devices, the image plane, if necessary one or more lens base layers and one or more lens layers, or exclusive production of optical lenses whose lens layers or, if necessary, braille characters Combine with text and image information to create their required layers. This can be done in a single continuous pass or in several successive passes through the same or another downstream application device.
