PROCESS FOR THE REALIZATION OF TRANSFERABLE IMAGES SPECIALLY FOR WALLS

Abstract: The invention is a new process for obtaining transferable images specially for walls in which the image is first processed by computer, printed (upturned) on supports or on transfer paper, then an adhesive binder is laid off the chosen wall, the support or the transfer paper leant against the wall is plugged back to front. Original images perfectly transferred on the pre-treated wall are obtained. This process has the advantage that neither stencils nor standard production are required but each application is original since it is created by the user himself by means of a computer.

Description: TITLE PROCESS FOR THE REALIZATION OF TRANSFERABLE IMAGES SPECIALLY FOR WALLS DESCRIPTION This patent relates to the field of decorations and particularly regards wall decorations. Generally, the walls of houses, gardens or buildings are usually painted with one or more continuos colours for each wall. In some valuable houses or premises the walls are decorated with simple, complex, monochrome or polychrome drawings. The simple decorations such as hems, lines, strips or simple figures are firstly drawn with a fine pencil stroke which can be erased (or are drawn with the same colour of the figure) and then are filled with the colour by means of a brush or a spray gun. In case of decorations with brush and always in case of decorations with spray gun the outlines of the figure to be drawn are circumscribed by stencils so as to prevent the colour from smudging and to avoid haloes. As for the more complex decorations, such as strips with geometric or curvilinear patterns some stencils are being used, they are laid on the wall and coloured. The paint goes through the shaped holes of the stencil colouring the wall with the exact shape of the stencil. In order to realize drawings with two or more colours it is necessary to use one stencil for each colour shortly after that the previous one is dried. This kind of decorations is to be carried out by professional painters with the help of several stencils owing to the considerable exactness and ability required. In any case, even using the stencils it is impossible to carry out small decorations or to soften the colours. Said softened or small decorations have to be carried out manually by an expert painter or decorator. Transfers are well known, that is, drawings painted on a sheet of transfer paper. These drawings can be heat-transferred on various kind of materials by means of presses or calenders, but they can neither be transferred on rough surface or have wide dimensions. In order to overcome to the above cited drawbacks a new process for decorations has been studied and carried out, said process allows to perform decorations with drawings, photographic images and processing-images realized by computers completely personalized. The process for carrying out decorations or images transferred on a wall consists of the following phases. Firstly, the image or the decoration to transfer on the wall is drawn by means of a computer. This phase can be performed scanning an existing image or modifying an existing image or realizing the image required by computer. The digital image obtained is then processed, that is, its colours are corrected to balance the various chromatic differences between the monitor and the inks used, then the image is overturned in a specular way and if its dimensions are wide it can be divided into parts. The image" processed or divided is printed by means of proper electrostatic printer on transfer-paper roll using four colour inks (black, blue, red, yellow). The images is not colour printed on supports or on separated sheet but all the colours are printed on the same support or transfer sheet. An adhesive, preferably with polyvinyl alcohol, is laid off the toner spread on the transfer, whereas, on the surface in which the image is to be painted, a thin adhesive binder layer having suitable chemical physical specifications - preferably equal or similar to the which ones of the inks used for the print of the image - is laid off. Each support or transfer paper is placed on the wall in the right position so that the side with the image is turned towards the wall. A pressure (plugging) is performed on the back to front, that is, on the support or on the transfer paper in order to get the ink of the image to adhere perfectly to the configuration of the wall and to transfer at the same time all the ink on the wall. When the plugging is complete the support or the transfer paper is removed leaving the image, or the ink composing the image, on the adhesive binder spread on the wall, that is, on the wall itself. If the image consists of many parts the process to be used for the other parts is the same as described until now. Once that all the parts of the image are applied on the wall, a transparent varnish is laid off the whole image so as to protect the ink and the image from dust and scratches and make the image more luminous. The process above described offers many advantages as far as time, costs, resolution and dimensions are concerned. The necessary time is limited to process the image by computer, to print it on a roll or on a transfer support, and to apply it on the chosen wall. The costs for the image are moderate as it is not necessary to have expensive stencils or expensive printing systems. The resolution obtained is very high as the digital printers can print continuos shading and single-coloured dots in the order of some split millimetres, this cannot be obtained by means of a normal typographic process and not even by a manual execution of the wall painting. The actual dimensions of the image can be huge as the images with huge dimensions are being split up in several parts with smaller dimensions easier to handle. The new process allows even a person who is not familiar with colours to obtain images with a simple application. The new process allows to obtain complex decorations in a quick, simple and easy way, as well as photographic copies, and any simple and/or polychrome image, even with minute details, processed by computer; all these decorations and images can be perform on rough masonry surface. If the decoration has to be removed, it can be easily covered with the same paint used for the wall or with a different one according to the user's preferences. The above are the basic outlines of the invention, on the basis of which the technician will be able to provide for implementation; therefore any change which may be necessary upon implementation is to be regarded as completely protected by the present invention. With reference to the above description the following claims are put forth.

Claims: CLAIMS \__ Process for the realization of transferable images specially for walls characterized in that it includes firstly the processing of the image by computer, the print (upturned) of the image on rolls or supports of transfer paper, the laying of adhesive binder on the wall and the plugging of the support or the transfer paper leant against the wall. _2__ Process for the realization of transferable images specially for wall according to claim 1, characterized in that the adhesive binder for the wall has the same chemical physical specifications of the inks used for printing the image. 3_, Process for the ralization of transferable images specially for walls according to claim 1, characterized in that the print on transfer paper is performed by means of electrostatic printer. _ Process for the realization of transferable images specially for walls according to claims 1, 2, characterized in that a thin layer of varnish is laid off the image transferred on the wall.
