Surface decoration having a 3-dimensional effect, and method of producing a surface decoration having a 3-dimensional effect, as well as utilization of a decoration having a 3-demensional effect

Abstract: A surface decoration having a 3-dimensional effect, for placement on a surface, comprising a transparent base sheet of film (1), a printed design (6) on at least a portion of the base sheet (1) and at least one object illustration (4) formed by the printed design (6). The decoration also has a shaded depiction (5a) of the object illustration (4) formed by the printed design (6), in which shaded depiction (5a) the printed design (6) is transparent.

Description: The present invention relates to a surface decoration having a 3-dimensional effect, for placement on a surface, comprising a transparent base sheet of film, a transparent printed design on at least a portion of the base sheet and at least one object illustration formed by the printed design and a non-transparent body color print or cover sheet. The invention further relates to a method of producing a surface decoration having a 3-dimensional effect, comprising an object illustration formed by a monochrome or multicolored transparent printed design, where a body color print (opaque pigment) or a non-transparent film sheet is applied to a transparent base sheet of film over a portion of the base sheet surface, wherein the printed design is applied over at least a portion of the base sheet of film. The invention also relates to a utilization of a surface decoration. It is known to apply decorations, for example in the form of a company emblem or an advertisement, to various kinds of surfaces. Accordingly, it is also known to apply such decorations to the floor. However, these decorations have hitherto been executed in such a way as to give only a 2-dimensional effect or, at best, to produce a poor 3-dimensional effect. An example of this is shown in European Patent Application 656.265, which shows a decoration where a printed picture, consisting of transparent colors, is printed on the back side of a transparent sheet of film. Over a large part of this printed picture it is printed a print of non-transparent color, which is placed in a screen consisting of larger or smaller dots. The aim of this is to give an impression to the viewer that different parts of the decoration is in different distances from the viewer. By introducing a screen of larger dots, the part of the decoration being within this screen is said to give the impression of being at a greater distance from the viewer than other parts of the decoration being within a screen of smaller dots of no screen at all. If at all, this way of building a decoration will give a bad impression of 3-dimensional effect. US-A-4 505 968 describes a flooring sheet with a non-transparent bottom layer, a transparent intermediate layer and a transparent top layer. Between the top layer and the intermediate layer an opaque pattern is provided. The opaque pattern is supposed to throw a shadow on the bottom layer when light is projected from above the top layer. To get the 3-dimensional effect, a certain distance between the pattern and the bottom layer must exist. US-A-5 458 931 describes a medallion, which utilises a similar technique as above, in which a pattern is throwing a shadow on the surface of a bottom. US-A-5 032 711 shows a display for motor vehicles in which the object is to achieve different colors in day light and in darkness when ultraviolet light is projected on the display. The dial pattern may cast a shadow, but here also the shadow will be dependent on distance between the pattern and the surface on which the shadow falls and the light setting. The aim of the present invention is to improve the 3-dimensional effect of such a surface decoration. This is achieved by a shaded depiction of the object illustration formed by a part of the printed design talling outside of the body color print, in which shaded depiction the printed design is transparent, as well as in a method of producing a surface decoration, in that the surface of that part of the printed design forming the object illustration is arranged to coincide with the surface area of the body color print or the non-transparent film, and the surface area of another part of the transparent printed design is arranged to fall outside the surface area of the body color print or the non-transparent film, whereby this part of the design is formed as a shaded depiction of the object illustration. By utilizing a transparent base sheet -- as opposed to the conventional opaque base sheet -- as the background supporting the printed design, it is possible by the additional use of transparent decorating colors to achieve the effect that, for example, the floor's surface is shining through the decoration. Over a portion of the decoration there may be applied a non-transparent body color (opaque pigment) and/or an opaque cover sheet of film, rendering the decoration opaque over portions of its decorative surface. On parts of the decorative surface such as, for example, where it is desired to create a shadow effect of the opaque portion of the decoration, no body color is used, and the "shadow" thereby becomes transparent. The result is that it is possible to depict an object that is casting a "shadow" across, for example, a floor. The invention will now be described in more detail with reference to the accompanying figures, where: Figures 1 - 5 show the production of the decoration in stages, and Figure 6 shows a finished decoration placed on a floor. In producing the decoration, one first provides a transparent base sheet of film, which is designated by reference number 1 in Figure 1. The transparent base sheet 1 may be precoated with a layer of glue 2, or said glue layer may be applied at a later stage. To the top side of the transparent base sheet 1, over at least a portion of the surface thereof, is applied a body color (opaque pigment ) 3, or a cover sheet of film. The body color or the cover sheet is non-transparent, and is employed as a base for the decorating colors that will be applied later. The body color 3 should be light, and preferably white. This is to avoid giving an undesirable color cast to the decorating colors. In Figure 2 the body color 3 is shown applied to a section 4 of base sheet 1, whereupon later a print 6, which is to form an object illustration later is to be applied, while on another section 5 of base sheet 1, no body color has been applied. As shown in Figure 3, one or more transparent decorating colors 6 are then applied. The decorating colors may be placed on both section 4, to which the body color (opaque pigment) 3 has been applied beforehand, and part 5a, also denoted the shaded depiction 5a, of section 5, to which no body color has been applied. In the part 5a the print forms a shaded depiction 5a, which is to give the impression of a "shadow" from the object in the object illustration. Now the decoration can already be applied to a surface that is to be decorated, such as a wall, for example. However, for use on surfaces exposed to heavy wear, such as a floor, for example, it is practical to lay a protective film sheet 7 over the decoration, as shown in Figure 4. The protective film sheet is provided with a glue layer 8, which adheres to the decorating colors and/or to the base sheet. Alternatively, the glue layer may be applied to the top surface of the decoration before the protective film sheet is laid on. As can be seen from Figure 4, a section 5b of base sheet 1 has not been coated with either a body color or a decorating color. On this section 5b the protective film 7 with its glue layer 8 will lie in direct contact with base sheet 1, although this is not clearly apparent from the schematic illustration in Figures 4 and 5. Protective film sheet 7 may be corrugated on the surface thereof opposite the glue layer. In Figure 5 the finished surface decoration 10 is shown placed on a floor 9. Here, in section 4, the decorating colors will be able to be seen without floor 9 showing through them, and produce an illustration of an object with a complete coverage of saturated colors. In section 5a the decorating colors 6 will again be visible, but in this case the floor 9 will also show through the transparent decorating colors 6, and a dark print in this part will give the impression that the object in the object illustration is casting a shodow on the floor. In section 5b only the floor 9 will be visible through the transparent film sheets 1 and 7. In Figure 6 the finished result is presented. Here, the decoration 10 is laid on a floor 9. As is seen from Figure 6, sections 4 are completely covered by a color, i.e., a body color (opaque pigment) and a decorating color. Sections 5a are provided only with decorating color, and appear here as a "shadow" of the objects depicted in sections 4. The floor 9 is visible through the shadow. Base sheet 1 and/or protective film sheet 10 may extend outside sections 4 and 5a, which are coated with a color, but they may also be cut or trimmed so as to cover only the area that is coated with color. To obtain a partial translucent visibility of the floor, the body color (opaque pigment) over portions of the decoration may be thinned or toned down with a saturation in the range of from 0 to 100%. This can be accomplished by, for example, using a screen in printing the body color. In this manner, by printing the decorating colors in a screen corresponding to the screen used for the body color, it is possible to create an illusion of, for example, sand being strewn over a floor. The glue in glue layer 2 is preferably of a non-permanent type, permitting removal of the decoration. This is particularly important when the decoration is an advertisement, which is likely to be changed frequently. The glue in glue layer 8 may be permanent or non-permanent. The protective film should be thick and wear-resistant and is preferably corrugated on the surface in order to improve friction so as to avoid the risk of a slippery surface. The protective film sheet could be omitted in, for example, the decorating of a wall, but it would nevertheless be an advantage here, too. The body color or opaque pigment, and/or the decorating colors, is (are) preferably applied by means of electrostatic printing, but may also be produced by silk screening. The decorating colors preferably comprise 4-color prints, but if desired the decoration may also be printed in fewer colors, or even in shades of gray.
