The invention relates to technologieshave in the printing industry, in the manufacture decorative materials, while creating a protective and decorative coatings of ceramic products, glass and metal; decorative fact, memorial plaques and monuments, stained-glass Windows.

Known raster methods of non-contact recording of images and information on a surface of the carrier by dispensing costs colourful structures in the direction toward the surface through the use of inkjet printers (see patent UK 2220892, class B 41 J 3/04, 1998). In decorative fact, to create theatrical scenery, colored stained using the photolithography method, consisting in contact with an emulsion exhibiting photomasks. To protect the image from the harmful effects of the environment of the use of film protective coatings based on drying oils, varnishes, synthetic resins, high polymer materials (see patent RU 2012917, 1994). A known method of transfer of image to different surface using spray extraction principle of transfer (see U.S. patent 4839666, 1989 ). The method consists in the progressive scan readout optical image in the plane of its focus and the synthesis of a copy of this image on the surface.

To tenderness use on different substrates, such as ceramics, various fabrics;

- inability image transfer on contoured surfaces;

- low strength characteristics of the surface;

- low resistance (burnout).

The closest analogue of the proposed method of transfer of image to different surface is the method lies in the fact that you are doing a scan or pershimco image, display the image on the monitor associated with the computer, kadriruju, retouch the image and adjust the color on the monitor, remove or reverse image using a printer or copier on the transfer material and transfer the displayed image on a substrate by combining the transfer material with the image to the substrate (see Log for printers and publishers "Computer" Ed. Computer press, N 7, 1998, page 48).

The disadvantages closest analogue include low functionality due to the lack of specific modes of technological process, designed for different materials of the substrate; for various transfer materials. The known method does not take into account the conditions of use of the product on notoriety characteristics of the transferred image.

The objective of the proposed method of transfer of image to different surface is to develop technology transfer image with the use of modern computer hardware that provides increased durability, resistance and increased durability of the transferred image in terms of damaging effects, temperature and moisture.

This problem is solved due to the fact that the method of transfer of image to different surface, which consists in the fact that carry out the scanning of the image, display the image on the monitor associated with the computer, kadriruju, retouch the image, adjust the color on the monitor, remove or reverse image using a printer or copier on the transfer material and transfer the displayed image on a substrate by combining the transfer material with the image to the substrate, after the alignment transfer material, the substrate carry out their heat treatment for 10 seconds at a temperature of 50oC required for substrates made of fusible material, and for 30 min at 350oC for the substrate of refractory material, and then separating trasti by applying a polymer coating and heat treatment.

In Fig. 1 is a flow diagram of image transfer; Fig. 2 depicts the operation of the image transfer to the substrate of Fig. 3 depicts the operation of the image transfer to the substrate, made of glass, in this case, the image is protected by a glass surface, and the opposite image side is covered with a polymer coating. The essence of the proposed method consists in the following. The proposed method is based on application of modern computational technologies associated with the use of digital devices input and output images, computer-controlled.

The proposed method allows to carry out the process of image transfer on porcelain, earthenware, leather, textile, clay, glass, metal, plastic and other derivative materials.

A full description of the process image transfer is as follows:

scan pictures or input into the computer using optical systems that are compatible with your computer;

- processing program, a pixel graphics;

output through the printer or copier to transfer materials;

- the combination of the transfer material with the image of the product (the transfer of material from the workpiece (substrate), the image remains on the substrate;

- protection from external influences;

- heat treatment for 5 to 120 minutes at a temperature of 50-350oC.

The proposed method can be applied to various existing tools for input and output images.

To input graphical information can be used by existing scanners are three types of devices: drum, flatbed and specialized slide scanners. Scanning or digital retaking image is the input image into the computer using the equipment, to convert the optical image into digital. They use various types of scanners, digital cameras, video cameras, slide scanners. The image is displayed on the computer monitor. Using pixel graphics produce a crop, retouch, image and adjust its color. Remove the forward or reverse image using a printer or copier on the transfer material. Best image quality is obtained when using printers that use the principle of dry color printing MICRO DRY. The print head of the printer consists of 240 cell battery (included) heating the points size of 40 microns. Paint does not impregnate the paper, as it sticks to it, so the colors on the prints look brighter and cleaner. The image is not blurred and not smeared, does not tarnish over time and does not fade in the sun.

This technology allows you to print a color photo-realistic image on paper of any quality: on a postcard, on cardboard of a thickness of 0.23 mm, transparencies, self-adhesive tapes, plastic and foil. Photographic quality can be achieved when printing on photo paper. In addition, you can apply the transfer material in the form of transfer paper and film, in which images are transferred on different surfaces - book covers, boxes, posters, wood, plastic, fabric, and various items. Printers can print metallic paints (gold, silver). The strength characteristics of the transfer material are in the range 80-150 g/cm2. The resulting image on the transfer material is transferred onto a substrate (product) by combining the transfer material to the substrate. The transfer material may be combined with the product (substrate) of any shape, including cylindrical. After combining carry out heat treatment for 10 seconds to 30 minutes when the temperature is s (substrate). The heat treatment is characterized by a processing time of 10 sec at a temperature of 50oWith necessary for articles (substrates) made of fusible material, for example, from polyepoxide resin with wax additives, fusible transfer materials. The heat treatment up to 30 minutes and the temperature to 350oWith sets for articles (substrates) made of marble, granite, metal, glazed, tradeplace materials.

Intermediate regimes apply to products made from wood, thermoplastics.

Given the range of heat treatment is a violation of communication between the ink and the transfer material due to its softening. Is the adhesion of the image to the product (substrate) due to forces of adhesion. The strength of adhesion between the paint and the substrate is higher than the force between the ink and the transfer material, the surface of which is coated with a thin film. Then separate the transfer material from the substrate, which is easily separated from the layer of paint without damaging it. The force of adhesion between the paint and the substrate becomes higher if the product (substrate) coated with a glaze, which is usually in faience ware, decorative-art isdel is further transferred to the protection obtained on the substrate image from external destructive impacts by applying polymeric coatings and heat treatment during the 5-120mm min at a temperature of 50-350oC. as the material of the polymer coating is used polyepoxide resin, polyester resin powder type, as well as liquid varnishes, which do not interact chemically with the transfer image.

Then carry out the heat treatment within a 5-120mm min at a temperature of 50-350oWith substrates made of any material other than containing waxy components. The method essentially comprises thermal regimes for most existing transfer of materials and substrates. As a result of implementation of the proposed method of image transfer the image to the desired product with high quality, characterized by improved color gamut, high art and decorative level and protected from harmful environmental influences.

To ensure high reliability save transferred images as a protective material can be used screen is made of glass. In this case, output a live image on the transfer material. Carry out the heat treatment at the location of the glass screen on the image. After removal of the transfer material provide protection reverse Godara high functionality used equipment: scanners, computer printer. The use of the computer allows you to perform operations cropping, retouching, image and adjust its color.

Retouching, correction, installation images allow you to create (draw) any of their image or processing introduction image.

In the image processing includes:

- crop - change the image format, deletion or insertion in the original additional image elements;

- retouching - removing image defects with the use of computer drafting programs, pixel and vector graphics;

- coloring, color correction is the application of colors in any image.

This may be a different program that is widely used in printing and computer artists.

When the image output using output devices, use of organic and inorganic pigments for paper and film, to convert these images on any surface.

The heat treatment is carried out using electric heating chambers or by imposing on product rubber electrodes to create a local who aqueous radiation or hot air.

The method of transfer of image to different surface, which consists in the fact that carry out the scanning of the image, display the image on the monitor associated with the computer, remove the forward or reverse image using a printer on the transfer material and transfer the displayed image on a substrate by combining the transfer material with the image to the substrate, characterized in that after the alignment transfer material, the substrate carry out their heat treatment for 10 s at a temperature of 50oC required for substrates made of fusible material, and for 30 min at 350oC for the substrate of refractory material, and then separating the transfer material from the substrate and protect the resulting image from the external destructive impacts by applying a polymer coating and heat treatment.
