Printable aluminum foil

The invention relates to an article of manufacture. One with Translucent aluminum foil with paper on the back provides a base for the formation of a printed one Pattern. The mirror-like surface is printed by successive imprints of which at least some are translucent. In some areas of the foil all of the sequential ones are printed Shapes translucent. There is a translucent print on at least some parts of the printed form or pattern Coating present, which is arranged to the underlying adjacent translucent imprints that the incident light passes through it and through the neighboring forms underneath, in order to distinguish it from the mirror-like metallic surface to be reflected. This printed film is then on one side on a fiber board and the opposite side is treated to make it impervious to moisture. The order is then brought into conformity with the printed shape.

For many years there has been an increasing need for process, handcrafted, multi-material and multi-part existing items for use as decorative panels,

409834/0378

To reproduce billboards and billboards through mass production, exist. Because the cost of wood and metal, especially for work, is the need to process it and replacing lower cost materials has become more urgent. Accompanying the desire for a reproduction Achieving lower cost is the increasing need for a greater degree of realism or reproduction, which goes far beyond the level of known methods available. Since the end consumer also As it becomes more and more demanding, it is very important to have the highest level of realism in terms of factors such as aesthetic Achieving responsiveness, skin tones, hair colors, wood grain, fabrics, metals, etc.

The invention relates to the use of various printing techniques, combined with the blowing technique, in order to produce cheap surface shapes in large quantities Present appearances of reality and the real worth of the item being reproduced. There are many important differences when looking at a three-dimensional object and its plane color reproduction. To the extent where these differences are reduced to the drift or some other way of treating a flat printed form one can get closer to the impression of reality. To the extent that differences remain, one can counteract this effect by providing the viewer with other clues through the eye or feeling as to of the real article. The clues are impressions that the observer used to make with the object learned to connect, which move the observer to put three-dimensional marks in the printed form. The necessary clues can be a series, whereby each part of the series is of no great importance on its own which, however, in their entirety produce the desired impression on the viewer. One of those clues are "changing shadows". A moving observer

409834/0378

eighth of a three-dimensional object sees changing shadows or lighting, with these changes are not present when he is looking at a planar image of the object. The effects of changing Shadows are a clue in the subconscious that the object being viewed is three-dimensional. This Clues can be generated on a flat print again by using the viewed printed surface appropriately was driven. The "obvious" magnitude of the change the shadows seen by a moving viewer on the floating surface, too

emphasize, it is desirable to reduce or eliminate the "non-wandering" shadows that may be present. In other situations, the surfaces of real objects have texture and a coating (i.e. dull, glossy), which, combined with suitable color effects, create an "aesthetic impression" that does not get through Color effects alone can be reproduced. In each of these cases the moving eye of a beholder sees alternately miserable contrasts when looking at the real object. When he looks at a picture, the nonexistence destroys these changing contrasts create the illusion of reality. The combination of a pictorial reproduction of an object in connection with bustle, with a coating that is transparent and preferably colorless and the one high Has surface gloss, with point coating of various Types of gloss, can cause the "changing" contrasts in the perception of a moving viewer, to give the perception clues for reality. The effect of limited depth of a driven Reliefs can be enlarged using color contrasts, precisely arranged shadows, shimmering reflections, etc. Farther Many real objects have metallic parts with their own mirror-like or metallic luster. Fluid-

opportunities also show special metal-like reflections in addition to their basic high gloss ^M moisture. "None of these metal or liquid effects can be reproduced in a way by. Wood is printed on a flat, white vehicle shows different characteristics approaching reality, which have to be reproduced exactly in order to evoke the impression of reality.In addition to the color, the surface gloss or the dullness, the rise and fall of the grain and the feeling of the surface are necessary to give the impression of reality.

Realism, reality, metallic mirror-like qualities are interdependent and the key point for that Memory of the viewer. The impression of connecting the key points to give the impression of reality create, work together in the combination of the clues that are supplied to the faculty of perception to determine the To assume the presence of other indications, and in this way an overall effect greater than that is achieved Effect of the individual clues.

1 shows a plate 1, which consists of a base plate of a sulfur-bleached paper 2, over which an aluminum foil 3 is coated with glue or another adhesive 4. The film 3 is extremely thin, for example in the order of magnitude of 50.8 / dd. The paper 2 is much thicker than the film, for example of a thickness of 152.4 U,. The laminate 1 is sufficiently thin and flexible to run through the roles of a conventional printing machine. The paper base 2 is provided in order to facilitate the handling of the very thin aluminum foil 3 and to avoid its kinking. The entire outward-facing surface of the aluminum foil has a mirror-like surface with a high metallic luster. It is coated with a protective varnish or the like, which after drying or the like leaves a color-absorbing, clear, colorless, completely covering film 6. The outwardly directed surface of the film 3 has a silvery color. If a different color is desired, the surface is provided with a transparent coating 8 of lacquer or the like. In the desired color. A yellow coating 8 changes the appearance of the outwardly directed surface of the film 3 to a gold sheen.

The desired printing technique is then applied to the surface of the coated film 1 in order to achieve the desired color

409834/03 7 8

to create the permeability of a product, a copy or a design. For example, four-color screens are used positive color separations of a transparency produced in full size by conventional methods of lithography. Of these, a positive is made for white, leaving white ink on those areas of the translucent coating 6 is printed, which should not be metallic. While most of the white positive is full of white is covered, certain areas may not be fully covered. These white areas are for special finishing treatments the forms and desired effects determined.

A baseline drawing of Io is made of the positives, which form the guide for engraving a depressed shape made to be exactly matches the printed image. A blown up shape is also made. It will be an artistic one Delimitation in terms of the depth of the various drifted areas and the surface treatment of the various Areas of shape made i.e. polished, rough, engraved, etc.

The shape Io is lithographed on the outward one Surface of the prepared sheet 1 printed. The printing is done in successive steps by a lithographic Printing press, whereby the white color is first printed twice, while the remaining colors are printed in a predetermined one Sequence to be printed. The white color contains a special, very high white pigment content. The colors are either opaque or translucent depending on how the final pattern is desired. Since the lithographic System requires oil-based paints as opposed to solvent-based paints, the transparent paints must be made out Pigments in contrast to dyeable colors,

409834/03 7 8

and as a result of the hiding power of the pigment particles, the transparent colors are actually translucent. The patterns printed one after the other are different from each other regarding the transparency, the opacity, the color, the appearance of the texture, the type of color used or the thickness of the paint applied. In some areas, all of the superimposed patterns are translucent; in other A covered final appearance is desired in areas. It is desirable that the transparent imprints first, the covering imprints will be made later.

Some of the successive steps through the lithographic Printing presses can create a patch-like effect on the shape Io to create different surface textures, which are represented by the image to emphasize. For example, the printing method 12 can have special applications may be necessary if the texture of human hair 22 is to be represented, or if the required effect should be produced by the texture of fabric 25, or to create a special skin color effect 25, or the glitter of a gemstone 24 or the effect the cold of a glass 25 'to achieve in the picture. The patch-like effect is one of the final uses the pattern of the prepared sheet 1 or one of the last printing operations.

The special shine that metal typically exudes is achieved through the previous use of translucent colors decreased. In many cases it is desired to have something - often a maximum - of the lost characteristic metallic luster regain · Its restoration is through successive Application of a translucent final coating 13 achieved after the final printing operation. This coating is so arranged to the adjacent, underlying translucent or semi-translucent print that the daiaifffallende Light through the interlayers between him and

409834/03 7 8

the adjacent underlying printing patterns and that in the areas where all underlying patterns are translucent or semi-translucent occurs; in this way the light is reflected by the mirror-like surface. The fully covered surfaces can be produced before or after the final coating 12 described below.

After all printing operations have been completed, the sheet is provided with the final coating 13. This final coating will

/ Sieve applied by means of a roller or with a silk one with a thickness that is a multiple of the thickness, sometimes up to 50 times or more, of the colors applied. The final coating is clear polyethylene, methacrylate or a polyester varnish. This produces a luminous force which increases the appearance of the surface of the coated sheet 1 printed in this way. The special gloss that metal typically exudes is reduced by the use of translucent lithographic inks. This gloss is restored to a large extent by the translucent final layer, so that the surfaces that are intended to reproduce the metallic effects of the actual object produce an increased effect in this way. The end coating also protects the sheet from abrasion. Subsequent layers B _e with a blunting agent may be applied to specific areas to produce a final glossy, dull or translucent appearance of the surface. These coatings are usually applied using a silk screen . The sheet can then be cured in an oven.

The printed sheet 1 is then applied to a fiber board 16 by means of an adhesive 17. The board 16 has a thickness of the order of magnitude of 0.18 em. It mainly consists

409834/0378

made of Kraft fibers with a resin binder. The fibers can be what are known as "long" fibers, with a predominant one Fiber length greater than 2.5 cm. The binder is a water-resistant resin to prevent atmospheric moisture from being absorbed by the Kraft fibers. One Unperforated aluminum foil 18 is applied to the back of the fiberboard 16. The adhesive that makes the connection of the foils 1 and 18 used on the board 16 is of the type which allows relative sliding that of the intermediate surfaces takes place during the subsequent drift.

The foils on the opposite sides of the board 16 seal the board against the escape of moisture thus preventing the drying out that could cause warping. The aluminum foils on the opposite one Sides of the board 16 can be of the same thickness so that they can warp in the same way withstand one direction or another in which there might be a tendency to warp.

The layered, printed, and coated board is then made into the shape of the final outline of the finished part or the finished parts are cut and the individual parts are then positive on a mechanical driving press and negative molds pressed in accordance with the illustrated printed shape. The goings-on in some or all of them Surfaces can be a micro-drift, as shown at 19 *, where only a very shallow depth is driven, but at a sufficient angle for clear distinction or can be a deep drift, taking down to a deep Extent of 0.35 cm is driven as shown at 19

If the final product is to have shapes on both sides of the fiberboard, the aluminum foil 18 can be omitted and a slide 1 'can be used instead. The slide 1 * will subjected to the printing operation described above in connection with the printing of slide 1. Those on the two slides printed things can be identical, but one must be reversed or mirror image of the other, except of course, with printed words or the like. The foils 1 and 1 * are then attached to the fiberboard 16 in a manner stacked so that the shapes on foils 1 and 1 * match in those examples where there is a match it is asked for.

When an object, such as a display, has matching shapes on both sides, as described above, and was driven so that on one side the driven shape is concave as at 19 in Fig. 5, and that on the other Side is convex and such a display is mounted so that it can be seen first from one side and then from the other sees, for example, when the display is mounted so that it rotates, becomes a particularly remarkable impression generated. For example, assume that the image represents a cylindrical object such as a gas of water. On the one hand, the convex image, together with the printed image, forms an idea of a glass that extends outward from the film in the full radius of the curves of the glass, even if the actual outward extension is only a small fraction of an inch. From the other side, the image is actually concave, always

/ when there is still an idea of a thickness, whether the glass is

would actually extend outward from the plane of the film. Constantly viewed such ideas attract attention on yourself, which is a highly desirable job in advertising. Similar if the matching images are directional on two sides of an ad, such as left to right when looking from one side If you look at the slide, it will be oriented from right to left if you look at the slide from the other side. this can also be used in advertising to attract attention.
