METHOD FOR PRODUCING DECORATED SURFACES BY USING PRINTED

WALLPAPER

The subject of the invention is a method for producing decorated surfaces by using printed wallpaper, so decorated wall surfaces of large size can be produced, and fully perfectly integral picture surfaces can be ensured if the single wallpaper strips are accurately fitted even in case of using quite strong tone of colors.

Nowadays there is an ever-increasing demand for creating aesthetic and unique interiors surrounding us. Hanging wallpaper is an old method for decorating the walls bordering the interiors. People with sophisticated taste for their milieu, respectively those ones who find important to create a unique surrounding around them are less and less satisfied with the mass-produced wallpapers which can be bought in the commerce, made generally in matte, pastel colors. There is also great demand from public institutions, restaurants, hotels, offices, office buildings to provide certain rooms, respectively their certain walls with unique, specially decorated wall surfaces. The soft, indistincted pattern of the traditional, mass-produced, matte, pastel color wallpapers are not very sensitive if the fitting of the wallpaper strips put on the wall is not quite accurate, and it is slightly visible. However in case of wallpapers containing colors of strong hue and outlines, it can be quite disturbing if the fitting of the wallpaper strips can be noticed, it is very seldom that wallpapers of such pattern are available in the commerce.

Pictures that can be compiled from wallpaper elements of paper base wallpaper have been long available in the commerce. They are fitted to the wall in such a way, that the wallpaper strips getting next to each other are fixed to the wall with an overlap of one- two centimeters. Up to now the same method is used when posters of large size are formed.

In the state of the art the KR 2004 0067 721 Korean patent application published on 30 July 2004 makes known such a wallpaper, the edges of which are formed in such a way, that after their fitting to each other, the wallpapered surface is of spotless, beautiful appearance. The edges of the wallpaper are formed with a cogwheel in a way that they protrude and embed. The forming of the edges takes place in accordance with the pattern of the given wallpaper.

The US 4041 605 patent published on 16 August 1977 describes a manual wallpaper cutting tool, making possible the accurate cutting of the wallpaper along such a gap, which is situated between the wallpapered wall and a structural element placed next to it. A guiding part is provided with a conic unit, which leans the structural element next to it against the wall, and gradually feed the wallpaper into the gap. A projection joining the conic unit tangentially at one edge is pressed onto the wall to be wallpapered, and it presses the wallpaper evenly onto the wall. A cutting blade which can be extended selectively, that is a razor blade with one end is placed in the input part of the tip of the conic unit, and it is fixed there by a releasable fastener. The cutting edge of the blade is placed in a certain angle compared to the projection, opposite the buckling plane of the projection. An extending handle is fixed to the base of the conic unit, so the wallpaper- cutting tool can be used with the help of it.

The WO 2004 111 367 international patent application published on 23 December 2004 makes known an edge-material used during hanging wallpaper, which makes possible uniform, sophisticated wallpapering irrespective to the quality of the wall to be papered. The material of the edge is made of such a base part, which is situated on the corner of the vertical wall and the ceiling, or at the comer of the vertical wall and the floor. The edge-material has a wing part running parallel with the wall, and another wing part, running parallel with the ceiling or the floor. The wallpaper is stuck onto these wing parts. The material of the edge covers the uneven surface of the wing part, so no filling in is needed. The edge-material has a cutting line, so a part of the wallpaper can be carefully stripped off. The advantage of the edge-material is, that it hides the fastenings of the wing parts with the glued wallpaper. In such a way a sophisticated, accurate wallpapering is made possible.

The US 5744 217 patent published on 28 April 1998 describes such a wallpaper provided with a decorative picture, which has a raw material suitable to be fitted to the wall, and a covering part which can be fastened to the raw material. The covering layer consists of several plaited metal foil parts. Each metal foil part has a front and a back part. There is a thin, flexible material joined at the back of each metal foil part. The decorative picture is fixed to the front of the metal foil parts. To provide decorative wallpapers, several thin, flexible materials provided with metal foil part are needed. The thin, flexible material of each metal foil part is fastened to a second thin, flexible material.The decorative picture of the metal foil parts is created by painting. The painted metal foil parts and the second thin, flexible materials are treated in such a way, that a plaited decorative picture is created. The second thin, flexible material is fixed onto a raw material. To provide wallpaper-containing parts of the decorative picture, several thin, flexible material with metal foil parts are needed. Each parts of the decorative picture are placed one after the other on the wall. Then the second thin, flexible material of each part of the picture is fixed to the appropriate part of the wall.

The US 6024 821 patent published on 15 Febr 2000 makes known a method of continuous positioning of two adjacent wallpaper strips on the surface. During the process one edge of the first wallpaper strip is fitted to the appropriate part of the adjacent wallpaper strip. During the process the wallpaper strips are in an angle determined in advance and wallpapers of dominant, emphatic patterns are used. The steps of the method are as follows: First a transparent plastic plate is placed above the first wallpaper strip, then a line outlining the pattern on the wallpaper is marked on the transparent plastic plate. Then the transparent plastic plate is placed in an angle determined in advance above the second wallpaper strip in such a way, that the contour outlines the pattern on the second wallpaper strip. Following this the transparent plastic plate and the edge of the second wallpaper is positioned anew in such a way, that it is adjusted to the appropriate edge of the first wallpaper strip, then the first wallpaper strip, the second wallpaper strip and the transparent plastic plate are cut along the line at the same time.

The drawbacks of the above mentioned methods and those used in practice are, that it is not possible to create decoration surfaces covering large surfaces with their help in such a way, that the decorated surface create an perfectly integral surface, respectively the fitting of single parts of the picture can take place easily, accurately and with great safety.

When working out the solution according to the invention we aimed to elaborate a method, with the help of which wall surfaces of large size can be provided with unique decoration surfaces, pictures, in such a way, that even in case of strong, dominant colors and outlines requiring especially accurate fitting, the decoration, the picture put up on the wall surface can appear as a perfectly integral picture surface, on the whole surface.

When creating the solution according to the invention we realized, that in case a wallpaper of vlies carrying material as raw material is used to form the decorative surface and the appropriate picture detail of the decorative surface is put on the wallpaper of vlies carrying material with the help of a digital printer, in given case with ultra-violet printing, and the wallpaper strips created this way are cut with proper accuracy, then fixed on the carrying surface in such a way, that only the carrying surface is provided with the adhesive and not the back of the wallpaper, and the wallpaper strips are arrayed next to each other on a vertical reference line in such a way, that the first one is put on the vertical reference line, the next one always next to the previous one, then the set aim can be achieved.

The invention is a method for producing decorated surfaces preferably by using printed wallpaper, and during said method a picture divided into several units conforming with wallpaper strips that can be fitted next to each other on a common wallpaper raw material, and these wallpaper strips are put on in conformity with the picture and are fixed on the surface, in given case on the wall to be covered by adhesive, furthermore during putting up, the wallpaper strips are fitted to each other and cut if needed. The method according to the invention is characterized by that, a vlies carrying material, consisting of the mixture of textile, cellulose and binding material is used as the raw material of the wallpaper strips serving for forming the decorative surface, the picture elements appropriate for the decoration surface are printed on the vlies carrying material divided on wallpaper strips by digital printer, in given case a UV-head ink-jet industrial printer emitting paint of synthetic base, and the printed wallpaper strips created this way are fixed on the carrying surface with adhesive in such a way, that only the carrying surface where the wallpaper strip will be placed is smeared with the applied adhesive, the back side of the wallpaper strip is not smeared, furthermore the wallpaper strips are arrayed next to each other along a vertical reference line according to a calibrated layout plan, in such a way, that the first one is fitted on the vertical reference line, and the next one in turn is fitted adjacent to the previous one, and resulting from this the wallpaper strips are placed on the carrying surface, in given case on the wall in such a way, that the greatest distance of the adjacent wallpaper strips along the fitting lines is: Δl < 0.3mm. In one preferred application of the method according to the invention, the material of the vlies carrying material is preferably a flexible, white material with smooth surface, or with structured surface layered with plastic foam pattern.

In another preferred application of the method according to the invention, the adhesive applied is a wallpaper adhesive, in given case a wallpaper adhesive of methyl-celluloze base with synthetic resin reinforcement, or a lacquer, in given case a wood-protecting polyurethane lacquer.

In a further preferred application of the method according to the invention, the whole surface of the picture formed by the wallpaper strips is provided with adhesive.

In a further preferred application of the method according to the invention, the superfluous adhesive leaking out at the fittings of the placed wallpaper strips are removed from the surface of the picture.

In a further preferred application of the method according to the invention, the whole surface of the picture put up is provided with colorless matte protecting lacquer, preferably with wood-protecting polyurethane lacquer.

In a further preferred application of the method according to the invention, the positioning of the wallpaper strip into the input of the printer takes place in such a way, that the wallpaper strip run perpendicular on the down and up reeler of the printer.

In a further preferred application of the method according to the invention, the paint sent to the wallpaper strip by the UV-head industrial printer is a thermosetting plastic base paint setting at the effect of UV-light.

In a possible preferable concrete realization of the method according to the invention a vlies raw material of smooth surface is applied.

As a first step the picture to be put on the wall is created by photographing it or by scanning it in digital form, in given case in 65 dpi resolution, taking into consideration, that the wallpaper placed on the wall is typically viewed close by. A calibrated layout plan is made as well about the picture to be depicted.

As a second step certain elements of the picture - which picture can be chosen from the available portfolio, or it can be an own picture brought by the client - is printed on a flexible, preferably of white color vlies raw material of smooth surface composing of the mixture of textile fibre, cellulose and binding material, with an industrial printer - which can be baren, or flexo printing - preferably with an industrial UV-head inkjet printer. The material of the wallpaper is positioned in the input of the printer so that the wallpaper material runs in perpendicular way to the down and up reeler of the printer. The UV-head industrial printer sends small drops of a paint of thermosetting plastic base setting at the effect of UV-light on the wallpaper material. Then the UV-light head moves above the material. The paint sets 90-95% under the influence of the UV-light emitted by the UV-head, preventing so the paint to be absorbed into the capillaries of the wallpaper material of structured surface and to deteriorate the quality of the picture.

As a third step of the method, the wallpaper material including the picture elements are cut into wallpaper strips that can be well fitted in the following way. The flexible wallpaper strip provided with cutting marks at both ends is placed on a cutting machine in such a way, that the edge of the printed pattern is set parallel with millimeter accuracy with the plane of the cutting, then the set wallpaper material is cut with a very sharp knife, resulting in the production of the fittable wallpaper strips, the first, then the other wallpaper strips including the other picture elements.

As step four of the method the wall, serving as the receiving, carrying surface is prepared by the usual traditional way of glossing, filling in, light painting, and if needed, by polishing. The light color of the receiving surface is important not to let the possibly darker shade of the receiving surface through the wallpaper material containing the picture. The receiving, carrying surface should be completely homogeneous color this case, because the material to be placed on it is strongly translucent, and after placing it the color change of the wall behind the installed picture will show as well. Afterwards a vertical reference line is marked on the surface suitably prepared for wallpapering. This line is at the same time the fitting line of the wallpaper strip to be put first on the receiving, carrying surface.

As step five of the method a wallpaper adhesive usually applied with vlies wallpapers, preferably, a methyl-cellulose base wallpaper adhesive reinforced with synthetic resin is put on the surface to be covered by the decorating wallpaper in the size of the wallpaper strip to be put first. The wallpaper material itself should not be smeared with the adhesive, so the wallpaper material remains dry until it is put on the wall. In that case, if the wallpaper is put on in a wet place, then a wallpaper adhesive conforming to it should be applied. Instead of the wallpaper adhesive a matte lacquer can be used for fixing the wallpaper.

Afterwards the first wallpaper strip is placed on the reference line on the surface smeared with the adhesive. Following this the further wallpaper strips are placed in such a way, that in the course of placing, the next wallpaper strip is placed at eye level (150- 170 cm), preferably at 160 cm next to the wallpaper strip already placed there. Resulting from it the possible fitting faults will occur on the lower, respectively the upper part of the wallpaper, respectively correction might be needed mostly there.

Then the wallpaper adhesive is smeared next to the wallpaper strip already placed in the size of the surface to be covered next, and the appropriate wallpaper strip is placed on it so, that it fits vertically and horizontally to the adjacent wallpaper strip put on previously. Following this the superfluous adhesive as well as the adhesive smeared on the surface of the wallpaper should be removed from the whole surface of the wallpaper by wiping it with a wet sponge. During the fitting the wallpaper strip placed there earlier should be considered as reference line, onto which the edge of the next wallpaper strip is fitted in the following way.

Resulting from the connection with the wall smeared with the adhesive or the lacquer, the material of the vlies wallpaper gets slightly wet and becomes so slightly elastic. Due to this the wallpaper strip to be placed can be positioned by hand, that is the pattern can be accurately fitted at the edges. Resulting from the positioning the biggest fitting gap, the distance between the two, wallpaper strips containing the adjacent picture element along the full length of the fitting line is Δl < 0.3mm.

Following this on any side of the wallpaper strips already placed - on the right or on the left side -, according to the layout plan, additional wallpaper strips are placed as described before. The procedure should go on according to the layout plan along the full length of the surface to be covered until it is fully covered. Then - after having placed all the wallpaper strips containing the picture elements - the picture required shows on the wall.

As step six of the procedure the possible overextensions of the wallpaper strips, the superfluous surface parts are removed by cutting and preferably a protecting layer against mechanical effects is applied on the finished picture surface on the wall by using preferably matte lacquer on the wallpaper material forming the picture surface. After having applied the lacquer layer, if need be, at the fittings of the edges of the wallpaper strips corrections can be made with felt pens in conformity with the pattern. In given case preferably the edge of the wallpaper strips is printed right after cutting according to the color of the given surface.

In another possible preferable concrete realization of the method according to the invention structured vlies raw material with foamed surface is applied.

In the course of this, as a first step, the picture to be placed on the wall is produced in digital form by photographing or scanning, in given case in 65 dpi resolution, and a calibrated layout plan is made.

As a second step, certain elements of the picture - the picture can be chosen from the available portfolio, or it can be an own picture brought by the client - is printed on a flexible, preferably of white color vlies raw material of structured surface layered with plastic-faced foam pattern, composing of the mixture of textile fibre, cellulose and binding material, with an industrial printer - which can be baren, or flexo printing — preferably with an industrial UV-head inkjet printer. The material of the wallpaper is positioned in the input of the printer so that the wallpaper material run in perpendicular way to the down and up reeler of the printer.

The UV-head industrial printer sends small drops of a paint of thermosetting plastic base setting at the effect of UV-Iight on the wallpaper material. Then the UV-light head moves above the material. The paint sets 90-95% under the influence of the UV-light emitted by the UV-head, preventing so the paint to be absorbed into the capillaries of the wallpaper material of structured surface and to deteriorate the quality of the picture.

As a third step of the method the wallpaper material including the picture elements are cut into wallpaper strips that can be well fitted in the following way. The flexible wallpaper strip provided with cutting marks at both ends is placed on a cutting machine in such a way, that the edge of the printed pattern is set parallel with millimeter accuracy with the plane of the cutting, then the set wallpaper material is cut with a very sharp knife, resulting in the production of the fittable wallpaper strips, the first, then the other wallpaper strips including the other picture elements.

As a fourth step of the method the wall, serving as the receiving, carrying surface is prepared by the usual traditional way with glossing, levelling, light painting, and if needed, by polishing. The light color of the receiving surface is important not to let the possibly darker shade of the receiving surface through the wallpaper material containing the picture.

In case of using a structured vlies raw material the receiving, carrying surface does not have to be entirely homogeneous color. If the receiving, carrying surface under the wallpaper is white, or of quite light color, then only the color of the picture appearing on the wallpaper will be visible. In case the receiving, carrying surface under the wallpaper is of dark tone, then the color of the picture appearing on the wallpaper can be seen on the protrusions of the foam layer, and the dark color of the wall will show at the indenture of the foam layer. This solution can bring very interesting color effects and ambience effects. Afterwards a vertical reference line is marked on the surface suitably prepared for wallpapering. This line is at the same time the fitting line of the wallpaper strip to be put first on the receiving, carrying surface.

As step five of the method a wallpaper adhesive usually applied with vlies wallpaper, preferably, a methyl-cellulose base wallpaper adhesive reinforced with synthetic resin is put on the surface to be covered by the decorating wallpaper in the size of the wallpaper strip to be put first. The wallpaper material itself should not be smeared with the adhesive, so the wallpaper material remains dry until it is put on the wall. In that case, if the wallpaper is put on in a wet place, then a wallpaper adhesive conforming to it should be applied.

Afterwards the first wallpaper strip is placed on the reference line on the surface smeared with the adhesive. Following this the further wallpaper strips are put on in such a way, that in the course of placing, the next wallpaper strip is placed at eye level (150- 170 cm) preferably at 160 cm next to the wallpaper strip already placed there. Resulting from it the possible fitting faults will occur on the lower, respectively the upper part of the wallpaper, respectively correction might be needed mostly there.

Then the wallpaper adhesive is smeared next to the wallpaper strip already placed in the size of the surface to be covered next, and the appropriate wallpaper strip is placed on it so, that it fits vertically and horizontally to the adjacent wallpaper strip put on previously. Following this the superfluous adhesive as well as the adhesive smeared on the surface of the wallpaper should be removed by wiping it with a wet sponge from the wallpaper. During the fitting the wallpaper strip placed there earlier should be considered as reference line, onto which the edge of the next wallpaper strip is fitted in the following way.

Resulting from the connection with the wall smeared with the adhesive, the material of the vlies wallpaper gets slightly wet and becomes so slightly elastic. Due to this the wallpaper strip to be placed can be positioned by hand, that is the pattern can be accurately fitted at the edges. Resulting from the positioning the biggest fitting gap, the distance between the two wallpaper strips containing the adjacent picture element along the full length of the fitting line is Δl < 0.3mm.

Following this on any side of the wallpaper strips already placed - on the right or on the left side -, according to the layout plan, additional wallpaper strips are placed as described before. The procedure should go on according to the layout plan along the full length of the surface to be covered until it is fully covered. Then - after having placed all the wallpaper strips containing the picture elements — the picture originally required appears on the wall.

As step six of the procedure the possible overextensions of the wallpaper strips, the superfluous surface parts are removed by cutting and preferably a protecting layer against mechanical effects is applied on the finished picture surface on the wall by using preferably matte lacquer on the wallpaper material forming the picture surface. After having applied the lacquer layer if need be, at the fittings of the edges of the wallpaper strips corrections can be made with felt pens in conformity with the pattern. In given case preferably the edge of the wallpaper strips is printed right after cutting according to the color of the given surface.

The method according to the invention is set forth by the following Figures:

The Fig 1 shows the first step of a possible, preferable realization of the method according to the invention, by marking the reference line and putting on the first wallpaper strip.

The Fig 2 shows the second step of a possible, preferable realization of the method according to the invention, by putting on the second wallpaper strip to the right next to the first wallpaper strip.

The Fig 3 shows the third step of a possible, preferable realization of the method according to the invention, by putting on the third wallpaper strip to the right next to the second wallpaper strip.

The Fig 4 shows the further steps of a possible, preferable realization of the method according to the invention, by putting on the further wallpaper strips right to the reference line.

The Fig 5 shows the further step of a possible, preferable realization of the method according to the invention, by putting on the wallpaper strip to the left next to the first wallpaper strip. The Fig 6 shows the interpretation of the fitting and tolerance of adjacent wallpaper strips during the realization of the method according to the invention in the A detail of the Fig 5.

The Fig 1 shows the first step of a possible, preferable realization of the method according to the invention, by marking the reference line and putting on the first wallpaper strip. It can be seen in the Figure, as the first wallpaper strip 4 is stuck to the right of the reference line 2 marked on the carrying surface 1. It is stuck in such a way, that the carrying surface 1 is provided with the adhesive 3 in the full width of the first wallpaper strip 4 and the first wallpaper strip 4 is stuck onto the part of the carrying surface 1 provided with adhesive 3.

The Fig 2 shows the second step of a possible, preferable realization of the method according to the invention, by putting on the second wallpaper strip to the right next to the first wallpaper strip. It can be seen in the Figure, that the second wallpaper strip 4 is stuck to the right of the first wallpaper strip 4 stuck earlier, fitted to the right edge of the first wallpaper strip 4, in such a way, that the carrying surface 1 is smeared with the adhesive 3 to the right of the first wallpaper strip 4 in the width of the second wallpaper strip 4, then the second wallpaper strip 4 is stuck and fitted onto the part of the carrying surface 1 provided with adhesive 3.

The Fig 3 shows the third step of a possible, preferable realization of the method according to the invention, by putting on the third wallpaper strip to the right next to the second wallpaper strip. It can be seen in the Figure, that the third wallpaper strip 4 is stuck to the right of the second wallpaper strip 4, fitted to the right edge of the second wallpaper strip 4, in such a way, that the carrying surface 1 is smeared with the adhesive 3 to the right of the second wallpaper strip 4 in the width of the third wallpaper strip 4, then the third wallpaper strip 4 is stuck and fitted onto the part of the carrying surface 1 provided with adhesive 3.

The Fig 4 shows the further steps of a possible, preferable realization of the method according to the invention, by putting on the further wallpaper strips right to the reference line. It can be seen in the Figure, that while going on with the procedure, the next wallpaper strips 4 are stuck in turn to the right, fitted to the right edge of the previous wallpaper strip 4, in the way described above, until all the wallpaper strips 4 forming the picture to be shown on the right side of reference line 2 are fixed onto the carrying surface 1.

The Fig 5 shows the further step of a possible, preferable realization of the method according to the invention, by putting on the wallpaper strip to the left next to the first wallpaper strip. It can be seen in the Figure, as the next wallpaper strip 4 is stuck to the left of the first wallpaper strip 4, fitted to the left edge of the first wallpaper strip 4 stuck earlier, in such a way, that the carrying surface 1 is smeared with the adhesive 3 to the left of the first wallpaper strip 4 in the width of the next wallpaper strip 4, then the next wallpaper strip 4 is stuck and fitted onto the part of the carrying surface 1 provided with adhesive 3. This process is being repeated until all wallpaper strips 4 forming the picture to be shown are fixed onto the carrying surface 1.

The Fig 6 shows the interpretation of the fitting and tolerance of adjacent wallpaper strips during the realization of the method according to the invention in the A detail of the Fig 5. It can be seen in the Figure, that the biggest distance between the two, adjacent wallpaper strips 4 along any of the fitting line is Δl. The distance Δl is determined according to the visual sharpness of the human eye. Visual sharpness is the angle limit, under which two points are percepted as separate by the human eye, An average human eye can make a difference between two points from one meter distance, if the distance of the points from each other is bigger, than 0.3mm. With the help of the technology worked out by us, in case of careful preparation it can be ensured a fitting accuracy below 0.3mm, i.e. Δl < 0.3mm, so the fitting can not be noticed from the typical perception distance of one meter.

The application of the method according to the invention can take place also in furter preferable ways, apart from those described in the Fig 3-5. In one of the further cases it is possible to place the wallpaper strips 4 first into one direction, in given case to the right- then to the left in turn - arrayed on the vertical middle reference line 2 marked in the middle of the carrying surface 1. In case of certain applications it is possible to mark the reference line 2 and start on one of the sides, either the left, or the right side. Then instead of placing in turn, placing going from one side towards the other side technique is used. It is important in every case that the new wallpaper strip 40 comes next to the previous one in order to enable proper fitting, so the decoration surface is continuously formed.

During a possible application of the method according to the invention, after having placed the wallpaper strips 4, the adhesive 3 running out from the fitting lines of the wallpaper strips 4 is smeared on the whole surface of the picture, if need be, supply additional adhesive quantity, so the whole surface of the picture is evenly smeared with adhesive 3. It makes possible, that the whole surface of the picture is free of spots, so a homogeneous appearance can be ensured. After the setting of the adhesive the whole surface of the picture is provided with colorless matte protecting lacquer, preferably with wood protecting polyurethane lacquer.

The advantages of the method according to the invention are the following:

Resulting from the especially aesthetic outcome of the wallpapering process according to the invention it is very well suited especially to cover the interior of any room in a flat, penthouses, offices, shops, restaurants, hotels. In case a structured wallpapering material is used during the process, a picture of 65 dpi resolution is sufficient for aesthetic decoration.

The wallpaper material used during the process according to the invention alloys the advantages of glass-fibre and foam-insert wallpapers. The wallpaper applied during the method according to the invention, due to its material is dimensionally more stable to a greater extent and makes possible the deformation necessary only for the positioning of the wallpaper strips forming the picture elements. The material of the wallpaper used is of great tensile strength, therefore it is well suited for eliminating smaller cracks in the wall. The applied material of the wallpaper is difficult to burn, so a flameproof to a greater extent material making possible safe use. Resulting from the material of the wallpaper there is no need for maculature, base wallpapering, therefore it is much easier to work with, than with glass-fibre or paper wallpaper.

A further advantage of the method according to the invention is, that the wallpaper to be used should not be soaked before sticking it, respectively the adhesive must be smeared on the wall only, and not on the back of the wallpaper, therefore it is also easy to work with, respectively the wallpaper strip gets slightly wet and so a slightly extendable during putting up, so it can be positioned by hand on the wall, that is the pattern can be precisely fitted at the edges. The applied wallpaper material does not shrink during setting, so the fitting lines do not come apart at all, that is, the result of the wallpapering is a strip-free, homogenous surface. The formation of the foam-insert of the wallpaper material can be varied, so patterns of different kind can be imitated through them, for example the pattern of a sack, a fibre, fish-bone etc.

A further advantage of the method according to the invention is, that due to the foam- insert of the wallpaper material used, in case the wall under the wallpaper is of dark tone, then the color of the picture on the wallpaper can be seen on the protrusions of the foam-insert, and at the indentures the dark color of the wall shows through. Resulting from this, very interesting color effects and ambience effects can be reached. The UV- light emitted by the UV-head of the industrial printer used during the procedure sets the applied thermosetting plastic base paint in 90-95% preventing the paint to be absorbed into the capillaries of the wallpaper material and so to deteriorate the quality of the picture.

Another advantage of the method according to the invention is, that due to the wallpaper material used, and the paint of synthetic base - at sticking the wallpaper strips including the picture elements, the superfluous adhesive at the edges of the wallpaper strips can be simply wiped out with a wet sponge. The quality of the strong, dominant paint color does not fade for a long time even under the effect of UV-light. The matte lacquer applied provides the wallpaper material forming the picture surface vulnerable to a greater extent due to the foam-layer protrusions, with a protective layer, so the matte lacquer protects it. Due to the matte lacquer used, during correction with felt-pen the material of the wallpaper does not absorb the paint from the felt-pen, so it does not deteriorate the quality of the picture. During redecorating the decoration wallpaper can be removed very easily from the wall, in a dry way, without soaking.

A further advantage of the method according to the invention is, that it can be ensured even in case of applying picture details of strong, dominant color and outlines, requiring especially precise fitting, that the decoration on the wall shows a perfectly integral picture surface. Resulting from positioning, the largest distance between two, adjacent wallpaper strips containing the adjacent picture elements is: Δl < 0.3mm. The calibrated layout plan makes possible the placing of the picture on the carrying surface exactly on the determined spot.
